(a) Simple checks
Before 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. See “(c) Jump starting” for further instructions.
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. See “(b) Starting a flooded engine” for further instructions.
(b) 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.
(c) Toyota Sienna Jump starting
To avoid serious personal injury and damage to your Toyota Sienna which might result from battery explosion, acid burns, electrical burns, or damaged electronic components, these instructions must be followed precisely.
If you are unsure about how to follow this procedure, it is strongly recommend that you seek the help of a competent mechanic or towing service.
The battery used for boosting must be 12 V. Do not jump start unless you are sure that the booster battery is correct.
Toyota Sienna JUMP STARTING PROCEDURE
If the booster battery is installed in another Toyota Sienna , make sure the vehicles are not touching. Turn off all unnecessary lights and accessories.
If required, remove all the vent plugs from the booster and discharged batteries. Lay a cloth over the open vents on the batteries. (This helps reduce the explosion hazard, personal injuries and burns.)
If the engine in the vehicle with the booster battery is not running, start it and let it run for a few minutes. During jump starting, run the Toyota Sienna engine at about 2000 rpm with the accelerator pedal lightly depressed.
4. Make the cable connections in the order a, b, c, d.
.
.
a. Connect the clamp of the positive (red) jumper cable to the positive ( ) terminal on the discharged Toyota Sienna battery.
b. Connect the clamp at the other end of the positive (red) Toyota Sienna jumper cable to the positive ( ) terminal on the booster battery.

c. Connect the clamp of the negative (black) Toyota Sienna jumper cable to the negative (-) terminal on the booster battery.
d. Connect the clamp at the other end of the negative (black) jumper cable to a solid, stationary, unpainted, metallic point of the Toyota Sienna with the discharged battery.
The recommended connecting point is shown in the following illustration:

If you have a flat tire in your Toyota Sienna
Reduce your Toyota Sienna speed gradually, keeping a straight line. Move cautiously off the road to a safe place well away from the traffic. Avoid stopping on the center divider of a highway. Park on a level spot with firm ground.
Stop the Toyota Sienna engine and turn on your Toyota Sienna emergency flashers.
Firmly set the Toyota Sienna parking brake and put the transmission in “P”.
Have everyone get out of the Toyota Sienna on the side away from traffic. And get far away from the roadway.
Read the following instructions thoroughly.
Do not continue driving with a deflated tire. Driving even a short distance can damage a Toyota Sienna tire beyond repair.
Compact spare tire
The compact spare tire is designed for temporary emergency use only.
The compact spare tire is identified by the distinctive wheel design and color and special wording “TEMPORARY USE ONLY” molded into the side wall of the tire.
The standard tire should be repaired and replaced as soon as possible.
To keep the compact Toyota Sienna spare tire noticeable, do not hide the wheel by a wheel cover or such.
The Toyota Sienna compact spare tire saves space in your luggage compartment, and its lighter weight helps to improve fuel economy and permits easier installation in case of a flat tire.
The compact spare tire can be used many times, if necessary. It has tread life of up to 4800 km (3000 miles) depending on road conditions and your driving habits. When tread wear indicators appear on the tire, replace the tire.
Your ground clearance is reduced when the compact Toyota Sienna spare tire is installed so avoid driving over obstacles and drive slowly on rough, unpaved roads and speed bumps. Also, do not attempt to go through an automatic car wash as the Toyota Sienna may get caught, resulting in damage.
1. Get the required tools and spare tire from your Toyota Sienna.
Toyota Sienna Jack
Jack handle
Wheel nut wrench
Toyota Sienna Spare tire
To prepare yourself for an emergency, you should familiarize yourself with the use of the jack, each of the tools and their storage locations.
Turn the jack joint by hand.
To remove: Turn the joint in direction 1 until the jack is free. To store: Turn the joint in direction 2 until the jack is firmly secured to prevent it flying forward during a collision or sudden braking.
To remove the spare tire;Open the back door and you will find the spare tire clamp bolt near the back door latch. Loosen the spare tire clamp bolt by turning it counterclockwise with the wheel nut wrench. After the tire is lowered completely to the ground, remove the holding bracket.
Compact spare tire— When storing the spare tire, put it in place with the inner side of the wheel facing up.
Except compact spare tire— When storing the spare tire, put it in place with the outer side of the wheel facing up.
Then secure the Toyota Sienna tire by repeating the above removal steps in reverse order to prevent it from flying forward during a collision or sudden braking.
Make sure to pull the tire straight up without catching on any other part.
Do not overtighten the bolt. Stop turning it when you begin to feel resistance on your hand.
After storing the Toyota Sienna tire, make sure it is securely locked by pushing it forward and rearward.

2. Block the wheel diagonally opposite the flat tire to keep the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block from the front for the front wheels or from the rear for the rear wheels.
3. Remove the Toyota Siennas wheel ornament.
Pry off the wheel ornament, using the beveled end of the wheel nut wrench as shown.

4. Loosen all the wheel nuts.
Always loosen the Toyota Sienna wheel nuts before raising the vehicle.
The nuts turn counterclockwise to loosen. To get maximum leverage, fit the wrench to the nut so that the handle is on the right side, as shown above. Grab the wrench near the end of the handle and pull up on the handle. Be careful that the wrench does not slip off the nut.
Do not remove the nuts yet—just unscrew them about one-half turn.
5. Position the Toyota Sienna jack at the correct jack point as shown.
Make sure the Toyota Sienna jack is positioned on a level and solid place.
6. After making sure that no one is in the Toyota Sienna, raise it high enough so that the spare tire can be installed.
Remember you will need more ground clearance when putting on the Toyota Sienna spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is a loose fit) and turn it clockwise. As the jack touches the vehicle and begins to lift, double-check that it is properly positioned.

7. Remove Toyota Siennas tires.
Roll the spare wheel into position and align the holes in the wheel with the bolts. Then lift up the wheel and get at least the top bolt started through its hole. Wiggle the tire and press it back over the other bolts.
Before putting on wheels, remove any corrosion on the mounting surfaces with a wire brush or such. Installation of wheels without good metal-to-metal contact at the mounting surface can cause wheel nuts to loosen and eventually cause a wheel to come off while driving. Therefore after the first 1600 km (1000 miles), check to see that the wheel nuts are tight.

8. Reinstall all the Toyota Sienna wheel nuts finger tight.
Reinstall the wheel nuts (tapered end inward) and tighten them as much as you can by hand. Press back on the tire and see if you can tighten them more.
9. Lower the Toyota Sienna completely and tighten the wheel nuts.
Turn the jack handle counterclockwise to lower the vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not use other tools or any additional leverage other than your hands, such as a hammer, pipe or your foot. Make sure the wrench is securely engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat the process until all the nuts are tight.

Steel wheel models, align the cutout of the wheel ornament with the valve stem as shown.
2. Then tap it firmly with the side or heel of your hand to snap it into place.
11. Check the Toyota Sienna air pressure of the replaced tire.
Do not forget to reinstall the tire inflation valve cap as dirt and moisture could get into the valve core and possibly cause air leakage. If the cap is missing, have a new one put on as soon as possible.
12. Restow all the tools, Toyota Sienna jack and flat tire securely.
As soon after changing wheels as possible, tighten the wheel nuts
