4186-1. Using the air conditioning system and defogger
SIENNA_OM_OM08007U_(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.

SIENNA_OM_OM08007U_(U)
WARNING
■To prevent the windshield from fogging up
●Do not use during cool air operat ion in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
●Do not touch the rear view mirror surfaces when the outside rear view mir-
ror defoggers (vehicles with outside rear view mirror defoggers) are on.
● Do not touch the glass at lower part of the windshield or to the side of the
front pillars when the windshield wiper de-icer is on. (vehicles with wind-
shield wiper de-icer)
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
●Do not place anything on the instrument
panel which may cover the air outlets.
Otherwise, air flow may be obstructed,
preventing the windshield defoggers
from defogging.
