■For quick cooling (vehicles with an air conditioning system)
Turn the dial to the “MAX A/C” position and select the recirculated air
mode.
■ Fogging up of the windows
●Vehicles with the button: 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.
● Vehicles with the button: 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 effective
in preventing outside air from entering the vehicle interior. During cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.
■ When the outside temperature is low (vehicles with the button)
The air conditioning system may not operate even when
is pressed.
■ 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.

WARNING
■To prevent the windshield from fogging up
● Do not set the air outlet selector dial to 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, blocking your vision.
■ To prevent burns (vehicles with outs ide rear view mirror defoggers)
Do not touch the rear view mirror surf aces when the outside rear view mirror
defoggers are 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
from defogging.
