6-1. Using the air conditioning system and defogger

■

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 wind-

shield 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 turned to “ON” position.

●

It is possible to switch to outside air mode at any time by pressing

.

■

Ventilation and air conditioning odors

●

To let fresh air in, set the air conditioning system to the outside air mode.

●

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 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

●

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
from defogging.
