3586-1. Using the air conditioning system
■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 is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
● If you turn 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 the out-
side/recirculated air mode button to the recirculated air mode. This is effec-
tive in preventing outside air from entering the vehicle interior. During
cooling operation, setting the recirculated 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.
■ 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 in the “ON” position.
● It is possible to switch to outside air mode at any time by pressing .
■ When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is selected.

■Ventilation and air conditioning odors
●To let fresh air in, set the air conditioning system to the outside air m\
ode.
● During use, various odors from inside and outside the vehicle may enter into
and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.
■ Air conditioning filter
→P. 440
CAUTION
■To prevent the windshield from fogging up
● Do not use
during cool air operation 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 (vehicles with rear view mirror defoggers and wind-
shield wiper de-icer)
● Do not touch the rear view mirror surfaces when the outside rear view mir-
ror 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.
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 to
defog.
