 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 temperature falls to nearly 32°F (0°C)

.

The dehumidification function may not operate even when

is selected.

417

 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.

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

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.

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.

6

 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.
