4146-1. Using the air conditioning system and defogger
SIENNA_OM_OM08013U_(U)
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after the “AUTO” button is pressed.
■ When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on
●In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically.
This may also reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine switch
is turned to the “ON” position (vehicles without a smart key system) or
IGNITION ON mode (vehicles with a smart key system).
● It is possible to switch to outside air mode at any time by pressing .
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Pressing “A/C” button on will dehumidify the air from the outlets and defog
the windshield effectively.
● If you turn “A/C” off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set
to the recirculated air mode. This is effective in preventing outside air from
entering the vehicle interior. During cooling operation, setting the recircu-
lated air mode will also cool the vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside temperature.

body, wheel wells and underside of the vehicle to remove any dirt
and dust.

chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
● Wipe away any water.

If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■Automatic car washes
●Before washing the vehicle:
• Fold the mirrors.
• Turn off the power back door system. (if equipped)
• Turn off the power sliding door system. (if equipped)
Start washing from the front of the vehicle. Make sure to extend the mirrors
before driving.

●Do not allow the nozzles of the car wash to come within close proximity of
the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ When using a car wash (veh icles with a smart key system)
● If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 6 ft. (2 m) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
● If the electronic key is inside the vehicle and a door handle becomes wet
during a car wash, a message may be shown on the multi-information dis-
play and a buzzer will sound outside the vehicle. To turn off the alarm, lock

under the floor of the vehicle. Water may also cause the body to rust.
■ Cleaning the inside of the rear wi ndow and the rear quarter windows
● Do not use glass cleaner to clean the rear window and the rear quarter
windows, as this may cause damage to the rear window defogger heater
wires or antenna. Use a cloth dampened with lukewarm water to gently
wipe the windows clean. Wipe the windows in strokes running parallel to
the heater wires or antenna.
● Be careful not to scratch or damage the heater wires or antenna.
