■ Defogging the rear window

and outside rear view mir-

rors

Defoggers are used to defog the

rear window and to remove rain-

drops, dew and frost from the

outside rear view mirrors.

■Fogging up of the windows

●The windows will easily fog up

when the humidity in the vehicle is

high. Turning “A/C” switch on will

dehumidify the air from the outlets

and defog the windshield effec-

tively.

equipped)

Close all windows. If dust thrown up

by the vehicle is still drawn into the

vehicle after closing the windows, it

is recommended that the air intake

mode be set to outside air mode and

the fan speed to any setting except

off.

This feature is used to prevent

ice from building up on the wind-

shield and wiper blades.

Press the windshield wiper de-

icer switch.

■Outside/recirculated air mode

●Setting to the recirculated air

mode temporarily is recom-

mended in preventing dirty air

from entering the vehicle interior

and helping to cool the vehicle

when the outside air temperature

is high.

The indicator

comes on when

the windshield wiper de-icer is

on.

The windshield wiper de-icer will

automatically turn off after a

period of time.

●Outside/recirculated air mode may

automatically switch depending on

the temperature setting or the

inside temperature.

●To reduce potential odors from

occurring:

• It is recommended that the air

conditioning system be set to out-

vehicle off.

• The start timing of the blower may

be delayed for a short period of

time immediately after the air con-

ditioning system is started in auto-

matic mode.

tem

Approximately 90 seconds after the

power switch turned to OFF, you

may hear sound coming from air

malfunction.

●When parking, the system auto-

culation throughout the vehicle,

helping to reduce odors that occur

when starting the vehicle.
