Jump Starting a Toyota Sienna

If your Toyota Sienna will not start First do Simple checks Before JUMP Starting making these checks, make sure you have followed the correct starting procedure and that you have sufficient fuel. If your Toyota Sienna  is equipped with the engine immobiliser system, also check whether the other keys will start the engine. If they work, your key may be broken. Have the key checked at your Toyota dealer. If none of your keys work, the system is possibly broken. Call your Toyota Sienna dealer. If the Toyota Sienna engine is not turning over or is turning over too slowly Check that the Toyota Sienna  battery terminals are tight and clean. If the battery terminals are O.K., switch on the interior light. If the Toyota Sienna light is out, dim or goes out when the Toyota Sienna starter is cranked, the battery is discharged. You may try jump starting.   If the light is O.K., but the engine still will not start, it needs adjustment or repair. Call a Toyota Sienna  dealer or qualified Toyota Sienna repair shop. Do not pull-or push-start the Toyota Sienna. It may damage the vehicle or cause a collision when the engine starts. Also the three-way catalytic converter may overheat and become a fire hazard.
If the Toyota Sienna engine turns over at its normal speed but will not start— Check that all the push-on connectors are tight. (For example, connectors at the Toyota Sienna spark plugs, ignition coil and/or distributor) If the connectors are O.K., the Toyota Sienna engine may be flooded because of repeated cranking.  Starting a flooded engine” for further instructions.  Starting a flooded Toyota Sienna engine If the engine will not start, your engine may be flooded because of repeated cranking. If this happens, turn the Toyota Sienna key to “START” with the accelerator pedal held down. Keep the key and accelerator pedal so for 15 seconds and release them. Then try starting the engine with your foot off the accelerator pedal. If the Toyota Sienna engine does not start after 15 seconds of cranking, release the key, wait a few minutes and try again. If the engine still will not start, it needs adjustment or repair. Call a Toyota dealer or qualified repair shop for assistance. Do not crank for more than 30 seconds at a time. This may overheat the Toyota Sienna starter and Toyota Sienna wiring systems. Toyota Sienna Jump starting Jump starting can be dangerous if done incorrectly. Therefore, to avoid harm to yourself or damage to your Toyota Sienna or battery, follow the Toyota Sienna jump starting procedures. If in doubt, we strongly recommend that you have a competent technician or towing service jump start your Toyota Sienna. Toyota Sienna EMERGENCY STARTING CAUTION Use only a 12-volt jumper system. You can damage a 12-volt starting motor, Toyota Sienna ignition system, and other electrical parts beyond repair by use of a 24-volt power supply (either two 12-volt batteries in series or a 24-volt motor generator set).WARNING - Battery Keep all flames or sparks away from the battery. The battery produces hydrogen gas which may explode if exposed to flame or sparks. Do not attempt to jump start the Toyota Sienna if the discharged battery frozen or if the electrolyte level low; the battery may rupture or explode. WARNING - Battery Never attempt to check the electrolyte level of he battery as this cause the battery to rupture or explode causing serious injury. Jump starting procedure1. Make sure the Toyota Sienna booster battery is 12-volt and that its negative terminal is grounded. 2. If the booster battery is in another Toyota Sienna, do not allow the Toyota Sienna's to touch.3. Turn off all unnecessary electrical loads.

4. Connect the Toyota Sienna jumper cables in the exact sequence shown in the previous illustration. First connect one end of a jumper cable to the positive terminal of the discharged Toyota Sienna battery (1), then connect the other end to the positive terminal on the booster battery (2). Proceed to connect one end of the other jumper cable to the negative terminal of the booster battery (3), then the other end to a solid, stationary, metallic point (for example, the Toyota Sienna engine lifting bracket)away from the battery (4). Do not connect it to or near any part that moves when the Toyota Sienna engine is cranked. CAUTION - Battery cables Do not connect the jumper cable from the negative terminal of the booster battery to the negative terminal of the discharged battery. This can cause the discharged battery to overheat and crack, releasing battery acid. Do not allow the jumper cables to contact anything except the correct battery terminals or the correct ground. Do not lean over the Toyota Sienna battery when making connections. Start the engine of the Toyota Sienna with the booster battery and let it run at 2,000rpm, then start the engine of the Toyota Sienna with the discharged battery. the cause of your battery discharging is not apparent, you should have your Toyota Sienna checked by an Authorized Toyota Sienna Dealer .Push-starting Toyota Sienna's equipped with automatic transaxle cannot be push-started. jump-starting. CAUTION Never tow a Toyota Sienna to start it because the sudden surge forward when the engine starts could cause a collision with the tow Toyota Sienna.
2. Turn on your Toyota Sienna emergency flashers. 3. Try to start the Toyota Sienna engine again. If your Toyota Sienna will not start, contact an authorized Toyota Sienna dealer or seek other qualified assistance.

Toyota Sienna Tire Selection and Maintenance

Toyota Sienna Tire care For proper Toyota Sienna maintenance, safety, and maximum fuel economy, you must always maintain recommended tire inflation pressures and stay within the load limits and weight distribution recommended for your Toyota Sienna. Recommended cold tire inflation pressures All Toyota Sienna tire pressures (including the spare) should be checked every day when the tires are cold. “Cold Tires” means the Toyota Sienna has not been driven for at least three hours or driven less than 1.6 km (one mile). Recommended pressures must be maintained for the best Toyota Sienna ride, top Toyota Sienna handling, and minimum tire wear. All Toyota Sienna specifications (sizes and pressures) can be found on a label attached to the Toyota Sienna. WARNING - Tire underinflation Severe underinflation (70 kPa (10 psi) or more) can lead to severe heat build-up, causing blowouts, tread separation and other tire failures that can result in the loss of Toyota Sienna control leading to severe injury or death. This risk is much higher on hot days and when driving for protracted periods at high speeds. Underinflation also results in excessive wear, poor Toyota Sienna handling and reduced fuel economy. Wheel deformation also is possible. Keep your tire pressures at the proper levels. If a tire frequently needs refilling, have it checked by an Authorized Toyota Dealer Overinflation produces a harsh Toyota Sienna ride, excessive wear at the center of the tire tread, and a greater possibility of damage from road hazards. Warm tires normally exceed recommended cold tire pressures by 28 to 41 kPa (4 to 6 psi). Do not release air fromwarm tires to adjust the pressure or the tires will be underinflated. Be sure to reinstall the tire inflation valve caps. Without the valve cap, dirt or moisture could get into the valve core and cause air leakage. If a valve cap is missing, install a new one as soon as possible. WARNING - Tire Inflation Overinflation or underinflation can reduce tire life, adversely affect Toyota Sienna handling, and lead to sudden tire failure.This could result in loss of Toyota Sienna control and potential injury CAUTION - Tire pressure Always observe the following: Check Toyota Sienna tire pressure when the tires are cold. (After Toyota Sienna has been parked for at least three hours or hasn't been driven more than 1.6 km (one mile) since startup.) Check the pressure of your spare tire each time you check the pressure of other tires. Never overload your Toyota Sienna. Be careful not to overload a Toyota Sienna luggage rack if your Toyota Sienna is equipped with one. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them Checking tire inflation pressure Check your Toyota Sienna tires once a month or more.Also, check the tire pressure of the spare tire. How to check Use a good quality gage to check tire pressure.You can not tell if your Toyota Sienna tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they're underinflated. Check the tire's inflation pressure when the tires are cold. - "Cold" means your Toyota Sienna has been sitting for at least three hours or driven no more than 1.6 km (1 mile). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the tire and loading Toyota Sienna information label, no further adjustment is necessary. If the pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Recheck the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. Tire rotation To equalize tread wear, it is recommended that the tires be rotated every 12,000 km (7,500 miles) or sooner if irregular wear develops.

During rotation, check the tires for correct balance. When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, outof- balance Toyota Sienna wheels, severe braking or severe cornering. Look for bumps or bulges in the tread or side of tire. Replace the tire if you find either of these conditions. Replace the tire if fabric or cord is visible. After rotation, be sure to bring the front and rear tire pressures to specification and check Toyota Sienna lug nut tightness. Disc brake pads should be inspected for wear whenever tires are rotated. Rotate radial tires that have anasymmetric tread pattern only from front to rear and not from right to left. WARNING Do not use the compact spare tire for tire rotation Do not mix bias ply and radial ply tires under any circumstances. This may cause unusual handling characteristics that could result in death, severe injury, or property damage. Toyota Sienna Tire replacement If the tire is worn evenly, a tread wear indicator will appear as a solid band across the tread. This shows there is less than 1.6 mm (1/16 inch) of tread left on the tire. Replace the tire when this happens. Do not wait for the band to appear across the entire tread before replacing the Toyota Sienna tire WARNING The Toyota Sienna ABS works by comparing the speed of the wheels.Tire size can affect wheel speed. When replacing tires, all 4 tires must use the same size originally supplied with the Toyota Sienna. Using tires of a different size can cause the Toyota Sienna ABS (Anti-lock Brake System) and ESC (Electronic Stability Control) to work irregularly. Compact spare tire replacement A compact spare tire has a shorter tread life than a regular size tire. Replace it when you can see the tread wear indicator bars on the tire. The replacement compact spare tire should be the same size and design tire as the one provided with your new Toyota and should be mounted on the same compact spare tire wheel. The compact spare tire is not designed to be mounted on a regular size wheel, and the Toyota Sienna compact spare tire wheel is not designed for mounting a regular size tire. Toyota Sienna Wheel replacement When replacing the Toyota Sienna metal wheels for any reason, make sure the new wheels are equivalent to the original Toyota Sienna factory units in diameter, rim width and offset. WARNING A wheel that is not the correct size may adversely affect Toyota Sienna wheel and bearing life, braking and stopping abilities, handling characteristics, ground clearance, body-to-tire clearance, snow chain clearance, speedometer calibration, headlight aim and bumper height. Wheel alignment and tire balance The wheels on your Toyota Sienna were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance. In most cases, you will not need to have your Toyota Sienna wheels aligned again. However, if you notice unusual tire wear or your Toyota Sienna pulling one way or the other, the alignment may need to be reset. If you notice your Toyota Sienna vibrating when driving on a smooth road, your wheels may need to be rebalanced. CAUTION Improper wheel weights can damage your Toyota Sienna's aluminum wheels. Use only approved wheel weights. WARNING - Replacing tires Driving on worn-out tires is very hazardous and will reduce braking effectiveness, steering accuracy, and traction. Your Toyota Sienna is equipped with tires designed to provide for safe ride and handling capability. tire and wheel that is different from the one that is originally installed on your Toyota Sienna. It can affect the safety and performance of your Toyota Sienna, which could lead to handling failure or rollover and serious injury. When replacing the tires, be sure to equip all four tires with the tire and wheel of the same size, type, tread, brand and load-carrying capacity. The use of any other tire size or type may seriously affect ride, handling, ground clearance, stopping distance, body to tire clearance, snow tire clearance, and speedometer reliability. It is best to replace all four Toyota Sienna tires at the same time. If that is not possible, or necessary, then replace the two front or two rear tires as a pair. Replacing just one tire can seriously affect your Toyota Sienna’s handling. Toyota Sienna Tire traction Tire traction can be reduced if you drive on worn tires, tires that are improperly inflated or on slippery road surfaces. Tires should be replaced when tread wear indicators appear. To reduce the possibility of losing control, slow down whenever there is rain, snow or ice on the road. Toyota Sienna Tire maintenance In addition to proper inflation, correct wheel alignment helps to decrease tire wear. If you find a tire is worn unevenly, have your dealer check the wheel alignement. When you have new tires installed, make sure they are balanced. This will increase Toyota Sienna ride comfort and tire life. Additionally, a tire should always be rebalanced if it is removed from the wheel. Tire sidewall labeling Federal law requires tire manufacturers to place standardized information on the sidewall of all tires. This information identifies and describes the fundamental characteristics of the tire and also provides the tire identification number (TIN) for safety standard certification. The TIN can be used to identify the tire in case of a recall.

1. Manufacturer or brand name Manufacturer or Brand name is shown. A tire’s sidewall is marked with a tire size designation. You will need this information when selecting replacement tires for your car. The following explains what the letters and numbers in the tire size designation mean. Example tire size designation: (These numbers are provided as an example only; your tire size designator could vary depending on your Toyota Sienna.) P185/65R14 86H P - Applicable Toyota Sienna type (tires marked with the prefix “P’’ are intended for use on passenger cars or light trucks; however, not all tires have this marking). 185 - Tire width in millimeters. 65 - Aspect ratio. The tire’s section height as a percentage of its width. R - Tire construction code (Radial). 14 - Rim diameter in inches. 86 - Load Index, a numerical code associated with the maximum load the tire can carry. H - Speed Rating Symbol. See the speed rating chart in this section for additional information. Wheel size designation Wheels are also marked with important information that you need if you ever have to replace one. The following explains what the letters and numbers in the wheel size designation mean. Example Toyota Sienna wheel size designation: 5.5JX14 5.5 - Rim width in inches. J - Rim contour designation. 14 - Rim diameter in inches Tire speed ratings The chart below lists many of the different speed ratings currently being used for passenger cars. The speed rating is part of the tire size designation on the sidewall of the tire. This symbol corresponds to that tire's designed maximum safe operating speed.S 180 km/h (112 mph) T 190 km/h (118 mph) H 210 km/h (130 mph) V 240 km/h (149 mph) Z Above 240 km/h (149 mph) 3. Checking tire life (TIN : Tire Identification Number) Any tires that are over 6 years, based on the manufacturing date, tire strength and performance, decline with age naturally (even unused spare tires). Therefore, the tires (including the spare tire) should be replaced by new ones. You can find the manufacturing date on the tire sidewall (possibly on the inside of the wheel), displaying the DOT Code. The DOT Code is a series of numbers on a tire consisting of numbers and English letters. The manufacturing date is designated by the last four digits (characters) of the DOT code. DOT : XXXX XXXX OOOO The front part of the DOT means a plant code number, tire size and tread pattern and the last four numbers indicate week and year manufactured. For example: DOT XXXX XXXX 1611 represents that the tire was produced in the 16th week of 2011. WARNING - Tire age Tires degrade over time, even when they are not being used. Regardless of the remaining tread, it is recommended that tires generally be replaced after six (6) years of normal service. Heat caused by hot climates or frequent high loading conditions can accelerate the aging process. Failure to follow this warning can result in sudden tire failure, which could lead to a loss of control and an accident involving serious injury or death. 4. Tire ply composition and material The number of layers or plies of rubber- coated fabric in the tire. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others. The letter "R" means radial ply construction; the letter "D" means diagonal or bias ply construction; and the letter "B" means belted-bias ply construction. 5. Maximum permissible inflation pressure This number is the greatest amount of air pressure that should be put in the tire. Do not exceed the maximum permissible inflation pressure. Refer to the Tire and Loading Information label for recommended inflation pressure. 6. Toyota Sienna Maximum load rating This number indicates the maximum load in kilograms and pounds that can be carried by the tire. When replacing the tires on the Toyota Sienna, always use a tire that has the same load rating as the factory installed tire. 7. Uniform tire quality grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: TREADWEAR 200 TRACTION AA TEMPERATURE A Tread wear The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one-and-ahalf times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use. However, performance may differ from the norm because of variations in driving habits, service practices and differences in road characteristics and climate. These grades are molded on the side-walls of passenger Toyota Sienna tires. The tires available as standard or optional equipment on Toyota Toyota Siennas may vary with respect to grade. Traction - AA, A, B & C The traction grades, from highest to lowest, are AA, A, B and C. The grades represent the tires ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Temperature -A, B & C The temperature grades are A (the highest), B and C. The grades represent the tire’s resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tires to degenerate and reduce tires life, and excessive temperature can lead to sudden tires failure. Grades A and B represent higher levels of performance on the laboratory test wheel than the minimum required by the law.Tire temperature The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat build-up and possible sudden tire failure. This can cause loss of Toyota Sienna control and serious injury or death. Tire terminology and definitions Air Pressure: The amount of air inside the tire pressing outward on the tire. Air pressure is expressed in kilopascal (kPa) or pounds per square inch (psi). Accessory Weight: This means the combined weight of optional accessories. Some examples of optional accessories are, automatic transmission, power seats, and air conditioning. Aspect Ratio: The relationship of a tire's height to its width. Belt: A rubber coated layer of cords that is located between the plies and the tread. Cords may be made from steel or other reinforcing materials. Bead: The tire bead contains steel wires wrapped by steel cords that hold the tire onto the rim. Bias Ply Tire: A pneumatic tire in which the plies are laid at alternate angles less than 90 degrees to the centerline of the tread. Cold Tire Pressure: The amount of air pressure in a tire, measured in kilopascals (kPa) or pounds per square inch (psi) before a tire has built up heat from driving. Curb Weight: This means the weight of a Toyota Sienna with standard and optional equipment including the maximum capacity of fuel, oil and coolant, but without passengers and cargo. DOT Markings: The DOT code includes the Tire Identification Number (TIN), an alphanumeric designator which can also identify the tire manufacturer, production plant, brand and date of production. GVWR: Gross Toyota Sienna Weight Rating GAWR FRT: Gross Axle Weight Rating for the front Axle. GAWR RR: Gross Axle Weight Rating for the rear axle. Intended Outboard Sidewall: The side of an asymmetrical tire, that must always face outward when mounted on a Toyota Sienna. Kilopascal (kPa): The metric unit for air pressure. Load Index: An assigned number ranging from 1 to 279 that corresponds to the load carrying capacity of a tire. Maximum Inflation Pressure: The maximum air pressure to which a cold tire may be inflated. The maximum air pressure is molded onto the sidewall. Maximum Load Rating: The load rating for a tire at the maximum permissible inflation pressure for that tire. Maximum Loaded Toyota Sienna Weight: The sum of curb weight; accessory weight; Toyota Sienna capacity weight; and production options weight. Normal Occupant Weight: The number of occupants a Toyota Sienna is designed to seat multiplied by 68 kg (150 pounds). Occupant Distribution: Designated seating positions. Outward Facing Sidewall: The side of a asymmetrical tire that has a particular side that faces outward when mounted on a Toyota Sienna. The outward facing sidewall bears white lettering or bears manufacturer, brand, and/or model name molding that is higher or deeper than the same moldings on the inner facing sidewall. Passenger (P-Metric) Tire: A tire used on passenger cars and some light duty trucks and multipurpose Toyota Siennas. Recommended Inflation Pressure: Toyota Sienna manufacturer's recommended tire inflation pressure and shown on the tire placard. Radial Ply tire: A pneumatic tire in which the ply cords that extend to the beads are laid at 90 degrees to the centerline of the tread. Rim: A metal support for a tire and upon which the tire beads are seated. Sidewall: The portion of a tire between the tread and the bead. Speed Rating: An alphanumeric code assigned to a tire indicating the maximum speed at which a tire can operate. Traction: The friction between the tire and the road surface. The amount of grip provided. Tread: The portion of a tire that comes into contact with the road. Treadwear Indicators: Narrow bands, sometimes called "wear bars," that show across the tread of a tire when only 2/32 inch of tread remains. UTQGS: Uniform Tire Quality Grading Standards, a tire information system that provides consumers with ratings for a tire's traction, temperature and treadwear. Ratings are determined by tire manufacturers using government testing procedures. The ratings are molded into the sidewall of the tire. Toyota Sienna Capacity Weight: The number of designated seating positions multiplied by 68 kg (150 lbs.) plus the rated cargo and luggage load. Toyota Sienna Maximum Load on the Tire: Load on an individual tire due to curb and accessory weight plus maximum occupant and cargo weight. Toyota Sienna Normal Load on the Tire: That load on an individual tire that is determined by distributing to each axle its share of the curb weight, accessory weight, and normal occupant weight and driving by 2. Toyota Sienna Placard: A label permanently attached to a Toyota Sienna showing the original equipment tire size and recommended inflation pressure. All season tires Toyota specifies all season tires on some models to provide good performance for use all year round, including snowy and icy road conditions. All season tires are identified by ALL SEASON and/or M+S (Mud and Snow) on the tire sidewall. Snow tires have better snow traction than all season tires and may be more appropriate in some areas. Summer tires Toyota specifies summer tires on some models to provide superior performance on dry roads. Summer tire performance is substantially reduced in snow and ice. Summer tires do not have the tire traction rating M+S (Mud and Snow) on the tire side wall. if you plan to operate your Toyota Sienna in snowy or icy conditions. Toyota recommends the use of Toyota Sienna snow tires or all season tires on all four wheels. Snow tires If you equip your Toyota Sienna with snow tires, they should be the same size and have the same load capacity as the original tires. Snow tires should be installed on all four Toyota Sienna wheels; otherwise, poor handling may result. Snow tires should carry 28 kPa (4 psi) more air pressure than the pressure recommended for the standard tires on the tire label on the driver's side of the center pillar, or up to the maximum pressure shown on the tire sidewall, whichever is less. Do not drive faster than 120 km/h (75 mph) when your Toyota Sienna is equipped with snow tires.

My Toyota Sienna Overheating

Toyota Sienna engine Cooling System. The Cooling System allows the Toyota Sienna engine to maintain the correct working temperature.

Toyota Sienna Heater and radiator hoses, and other Toyota Sienna engine parts, can be very hot. Do not touch them. If you do, you can be burned.
Do not run the Toyota Sienna engine if there is a leak. If you run the Toyota Sienna engine, it could lose all coolant. That could
cause an Toyota Sienna engine fire, and you could be burned. Get any leak fixed before you drive the Toyota Sienna.

The Toyota Sienna has an indicator to warn of Toyota Sienna engine overheating.
There is an Toyota Sienna engine coolant temperature warning light on your Toyota Sienna’s instrument panel. If an Toyota Sienna engine overheat warning is displayed but no steam
can be seen or heard, the problem may not be too serious. Sometimes the Toyota Sienna engine can get a little too hot
when the Toyota Sienna:
Climbs a long hill on a hot day. Stops after high-speed driving.
Idles for long periods in traffic.
If the overheat warning is displayed with no sign of steam:
Turn the air conditioning off.
Turn the heater on to the highest temperature and to the highest fan speed. Open the windows as necessary.
In heavy traffic, let the Toyota Sienna engine idle in N (Neutral)
while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the Toyota Sienna engine idle.
If the temperature overheat gage is no longer in the overheat zone or an overheat warning no longer
displays, the Toyota Sienna can be driven. Continue to drive the Toyota Sienna slow for about 10 minutes. Keep a safe
Toyota Sienna distance from the car in front of you. If the warning does not come back on, continue to drive normally.
If the warning continues, pull over, stop, and park the Toyota Sienna right away. If there is no sign of steam, idle the Toyota Sienna engine for three
minutes while parked. If the warning is still displayed, turn off the Toyota Sienna engine until it cools down.
You may decide not to lift the hood when this warning appears, but instead get service help right away.

If you do decide to lift the hood, make sure the Toyota Sienna is parked on a level surface.
Then check to see if the Toyota Sienna engine cooling fan is running. If the Toyota Sienna engine is overheating, the fan should be running.
If not, do not continue to run the Toyota Sienna engine and have the Toyota Sienna serviced.

When working near the Toyota sienna radiator cooling fan,  disconnect the fan motor lead or turn the ignition switch to the LOCK position. The fan is temperature controlled and can start at any time the
ignition switch is in the ON position. An electric Toyota Sienna engine cooling fan under the hood can start up even when the Toyota Sienna engine is not running and can cause injury. Keep hands, clothing, and tools
away from any underhood electric fan. You or others can be badly burned by hot coolant or steam from your radiator. If you see or hear steam coming from under the hood, don’t open the
hood until the radiator has had time to cool. Never try to open a cooling system pressure cap when the Toyota Sienna radiator is hot.


Adding only plain water to the cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. The Toyota Sienna’s coolant warning system
is set for the proper coolant mixture. With plain water or the wrong mixture, the Toyota Sienna engine could get too hot but you would not get the overheat warning. The Toyota Sienna engine could catch fire and you or
others could be burned. Check Toyota Sienna engine coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If coolant is dirty or rusty in appearance, the system should be drained, flushed, and refilled with fresh coolant. Check the front of the A/C condenser for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the condenser. Check the coolant recovery bottle tubing for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the bottle and radiator. Inspect the entire system for leaks. With the Toyota Sienna engine at normal operating temperature (but not running), check the cooling system pressure cap for proper vacuum sealing by draining a small amount of
coolant from the radiator drain cock. If the cap is sealing properly, the Toyota Sienna engine coolant (antifreeze) will begin todrain from the coolant recovery bottle. DO NOT REMOVE
THE Toyota Sienna COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush, and Refill
The system should be drained, flushed, and refilled at the intervals If the solution is dirty or contains a considerable amount of sediment, clean and flush with a reliable cooling
system cleaner. Follow with a thorough rinsing to remove all deposits and chemicals. Properly dispose of old antifreeze solution. Coolant and Fluids, Lubricants, and Genuine Toyota Sienna Parts”



Mixing of coolants other than specified Toyota Sienna engine coolants, may result in Toyota Sienna engine damage and
may decrease corrosion protection. Do not use plain water alone or alcohol-based
Toyota Sienna engine coolant (antifreeze) products. Do not use additional rust inhibitors or antirust products, as
they may not be compatible with the radiator Toyota Sienna engine coolant and may plug the radiator.
This Toyota Sienna has not been designed for use with Toyota Sienna coolants.
Adding Toyota Sienna Coolant
Your Toyota Sienna has been built with an improved Toyota Sienna engine coolant Toyota Sienna Antifreeze/Coolant 5 Year/100,000 Mile Formula
Use only high purity water such as distilled or deionized water when mixing the water/Toyota Sienna engine coolant solution. The use of lower quality water will reduce the amount of corrosion protection in the Toyota Sienna engine
cooling system.
it is the owner’s responsibility to maintain the proper level of protection against freezing according
to the temperatures occurring in the area where the Toyota Sienna is operated. Mixing coolant types will decrease the life of the Toyota Sienna engine coolant and will require more frequent coolant changes.
Toyota Sienna Cooling System Pressure Cap The cap must be fully tightened to prevent loss of coolant and to ensure that coolant will return to the radiator from the coolant recovery bottle.

The cap should be inspected and cleaned if there is any accumulation of foreign material on the sealing surfaces.
The warning words “DO NOT OPEN HOT” on the Toyota Sienna cooling system pressure cap are a safety precaution.
Never add coolant when the Toyota Sienna engine is overheated. Do not loosen or remove the cap to
cool an overheated Toyota Sienna engine. Heat causes pressure to build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the system is hot or under pressure. Do not use a pressure cap other than the one
specified for your Toyota Sienna. Personal injury or Toyota Sienna engine damage may result.
Disposal of Used Coolant
Used Toyota Sienna engine coolant requiring proper disposal. Check with your local authorities to determine the disposal rules for your
community. To prevent ingestion by animals or children, do not store Toyota Sienna engine coolant in open containers or allow it to remain in puddles on the ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for determining that the coolant level is adequate. With the
Toyota Sienna engine OFF and cold, the level of the coolant in the bottle should be between the ranges indicated on the bottle.


The radiator normally remains completely full, so there is no need to remove the radiator cap unless checking for
Toyota Sienna coolant freeze point or replacing coolant. Advise your service attendant of this. As long as the Toyota Sienna engine operating
temperature is satisfactory, the coolant bottle need only be checked once a month. When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do not overfill. When the Toyota Sienna is stopped after a few miles of operation, you may observe vapor coming
from the front of the Toyota Sienna engine compartment. This is normally a result of moisture from rain, snow, or high humidity accumulating on the radiator and being vaporized when the thermostat opens, allowing hot coolant to
enter the Toyota Sienna radiator. if your Toyota Sienna engine compartment shows no evidence of radiator or hose leaks, the Toyota Sienna may be
safely driven. The vapor will soon dissipate. Do not overfill the coolant recovery bottle. Check coolant freeze point in the radiator and in the coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be protected against freezing. If frequent coolant additions are required, or if the level in the coolant recovery bottle does not drop when
the Toyota Sienna engine cools, the cooling system should be pressure tested for leaks. Maintain coolant concentration at 50% Toyota Sienna engine coolant (minimum) and distilled water for proper
corrosion protection of your Toyota Sienna engine, which contains aluminum components.


Make sure that the radiator and coolant recovery bottle overflow hoses are not kinked or obstructed. Keep the front of the radiator clean. If your Toyota Sienna is equipped with air conditioning, keep the front of the
condenser clean, also. Do not change the Toyota Sienna thermostat for Summer or Winter operation. If replacement is ever necessary, install ONLY the correct type Toyota Sienna thermostat. Other designs may
result in unsatisfactory coolant performance, poor Toyota Sienna gas mileage, and increased emissions.

Toyota Sienna Cold Weather Starting

Toyota Sienna Cold Weather Starting
Extremely Cold Weather (Below 19°F) To ensure reliable starting at these temperatures, use of
an externally powered electric Toyota Sienna engine block heater (available from your authorized Toyota Sienna dealer) is recommended.

Toyota Sienna engine Toyota Sienna coolant Heater
The Toyota Sienna engine Toyota Sienna coolant heater, if available, can help in cold weather
conditions at or below 0°F for easier starting and better fuel
economy during Toyota Sienna engine warm-up. Plug in the Toyota Sienna coolant heater at least
four hours before starting your Toyota Sienna. An internal thermostat in the
plug-end of the cord will prevent Toyota Sienna engine Toyota Sienna coolant heater operation at
temperatures above 0°F .
To Use The Toyota Sienna engine Toyota Sienna coolant
Heater
1. Turn off the Toyota Sienna engine.
2. Open the hood and unwrap the
