Toyota Sienna Window Fogging
Interior fogging on the windshield can be quickly removed
by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side window
fogging becomes a problem increase blower speed.
Toyota Sienna windows tend to fog on the inside in mild but
rainy or humid weather.
The Toyota Sienna electric Rear Window Defroster Control is
located on the climate control. Press this button to
turn on the rear window defroster. A light above the
button will illuminate when the rear window defroster is
ON. The defroster automatically turns off after approximately
15 minutes of operation for the first push of the
button, and will turn off after approximately 8 minutes
for the second push of the button.
Outside Air Intake
When operating the system, particularly during the winter
months, make sure the air intake, at the right side of
the hood, is free of ice, slush, snow, or other obstructions
such as leaves. Leaves collected in the air-intake plenum
may reduce airflow and plug the plenum water drains.
Toyota Sienna Control Setting Suggestions for Various Weather Conditions
Slight changes in your Toyota Sienna engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C condenser
for an accumulation of dirt or insects.
Recirculation Control
Air is recirculated inside the Toyota Sienna. You
may choose between Bi-Level and Panel air
outlets while in this mode. Use this mode to
temporarily block out any outside odors,
smoke, or dust and to cool the interior rapidly upon
initial start up in very hot or humid weather.
Toyota Sienna CLIMATE CONTROLS
