air outlet position or is selected, the system will be set to recirculated air mode. While “MAX A/C” is selected, it is not possible to turn off the air conditioning.

Fan speed setting

Pressing the on/off switch to turns off the fan.

When the fan is off, pressing the on/off switch or turning the fan speed control switch clockwise will turn on the fan.

Switching between outside air and recirculated air modes

To change to recirculated air mode, press the recirculated air mode switch.

The indicator illuminates on the recirculated air mode switch.

To change to outside air mode, press the outside air mode switch.

The indicator illuminates on the out- side air mode switch.

Set cooling and dehumidifi- cation function

When the function is on, the indica- tor illuminates on the “A/C” switch.

Defogging the windshield

Press the windshield defogger switch.

Set the outside/recirculated air mode switch to outside air mode if the recirculated air mode is used.

To defog the windshield and the side windows quickly, turn the air flow and temperature up.

To return to the previous mode, press the windshield defogger switch again when the windshield is defogged.

When the windshield defogger switch is on, the indicator illumi- nates on the windshield defogger

switch.

Defogging the rear window and outside rear view mir- rors

A defogger is used to defog the rear window.

Press the rear window defogger switch.

The defogger will automatically turn off after a while.

When the rear window defogger switch is on, the indicator illumi- nates on the rear window defogger switch.

Defoggers are used to defog the rear window, and to remove raindrops, dew and frost from the outside rear view mirrors.

Press the rear window and out- side rear view mirror defoggers switch.

The defoggers will automatically turn off after a while.

When the rear window and outside rear view mirror defoggers switch is on, the indicator illuminates on the rear window and outside rear view mirror defoggers switch.

Fogging up of the windows

The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C” switch is on will dehumidify the air from the outlets and defog the windshield effectively.

If you turn “A/C” switch is 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 outside/recirculated air mode switch 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 falls to nearly 32°F (0°C)

The dehumidification function may not operate even when “A/C” switch is pressed.

Ventilation and air conditioning odors

To let fresh air in, set the air condi- tioning 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.

It is recommended that the air conditioning system be set to out- side air mode prior to turning the vehicle off.

When parking, the system auto- matically switches to outside air mode to encourage better air cir- culation throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

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 outside/recirculated air mode switch to the recirculated air mode. This is effective in prevent- ing 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 conditioning system is on

In order to reduce the air condi- tioning power consumption, the air conditioning system may switch to recirculated air mode automati- cally. This may also reduce fuel consumption.

Recirculated air mode is selected as a default mode when the engine switch is turned to ON.

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

Fogging up of the windows

The windows will easily fog up when the humidity in the vehicle is high. Turning “A/C” on will dehu- midify the air from the outlets and

tioning 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 out- side 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 con- ditioning system is started in auto- matic mode.

When parking, the system auto- matically switches to outside air

mode to encourage better air cir- culation throughout the vehicle, helping to reduce odors that occur when starting the vehicle.
