Other functions

Switching between outside air and recirculated air mo

 

Press .

 

The mode switches between outside air mode (indicator off) and recirculated air mode (indicator on) each time 
is pressed.

 Defogging the windshield

 

Defoggers are used to defog the windshield and front side windows.

1. Press .

   
   If the recirculated air mode is used, it will automatically switch to the outside air mode.

2. Perform the following operations accordingly:

•  to adjust the fan speed, turn .


•  To adjust the temperature setting, turn .


•  If the dehumidification function is not operating, press  to
  operate the dehumidification function.

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

Defogging the rear window and outside rear view mirrors

 

• Vehicles without outside rear view mirror defoggers

A defogger is used to defog the rear window.

Press .

 

The defogger will automatically turn off after a period of time.

• Vehicles with outside rear view mirror defoggers

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

Press .

 

The defoggers will automatically turn off after a period of time.

 Windshield wiper de-icer (if equipped)

 

This feature is used to prevent ice from building up on the windshield and wiper blades.

Press the switch to turn the system on/off.

The indicator comes on when the windshield wiper de-icer is on.

The windshield de-icer will automatically turn off after a period of time.

Air outlets

Location of air outlets

 

The air outlets and air volume change according to the selected airflow mode.

 

Adjusting the position of and opening and closing the air outlets

 

• Front center outlets

Direct air flow to the left or right, up or down.

 

• Front side outlets

Direct air flow to the left or right, up or down.

 

1. Closes the vent slide the knob to the most outward position.
2. Opens the vent

 

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 outside/ 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.
• Outside/recirculated air mode may automatically switch depending on the temperature setting or the inside temperature.

When the outside temperature exceeds 75ƒ‹f (24ƒ‹c) and the air conditioning system is on

 

• In order to reduce the air conditioning power consumption, the air conditioning 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, blocking 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 from defogging   To prevent burns   Do not touch the rear view mirror surfaces when the outside rear view mirror 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.
