Fan speed control: Adjusts the volume of air circulated in the vehicle.

Power: Press to switch the system on and off. When the system is off, it prevents outside air from entering the vehicle.

Air distribution control: Press to switch air flow from the windshield, instrument panel, or footwell vents on or off. You can distribute air through any combination of these vents.

Note: At least one of these buttons remain on while the system is on.

D Recirculated air: Press to switch between outside air and recirculated air. The air currently in the passenger compartment recirculates. This may reduce the time needed to cool the interior (when used with A/C) and reduce unwanted odors from entering your vehicle.

Note: Recirculated air may turn off (or prevent you from switching on) in all air flow modes except MAX A/C to reduce the risk of fogging.

Recirculation may also turn on and off in Panel or Panel/Floor air flow modes during hot weather in order to improve cooling efficiency.

146

Temperature control: Adjusts the temperature of the air circulated in your vehicle.

MAX Defrost: Turn to the right to switch on defrost. Air flows through the windshield vents and the fan adjusts to the highest speed. You can also use this setting to defog and clear the windshield of a thin covering of ice. The heated rear window also turns on when you select maximum defrost.

Note: To prevent window fogging, you cannot select recirculated air when maximum defrost is on.

MAX A/C: Turn to the left for maximum cooling. Recirculated air flows through the instrument panel vents, air conditioning turns on and the fan adjusts to the highest speed.

A/C: Press to switch the air conditioning on or off. Use A/C with recirculated air to improve cooling performance and efficiency.

Note: In certain conditions (for example, maximum defrost), the air conditioning compressor may continue to operate even though you switch off the air conditioning.

Heated seats: Press to switch the heated seats on and off. See Heated Seats (page 162).

Heated exterior mirrors: Press to switch the heated exterior mirrors on and off.

Note: Recirculated air may turn off (or prevent you from switching on) in all air flow modes except MAX A/C to reduce the risk of fogging.

Recirculation may also turn on and off in Panel or Panel/Floor air flow modes during hot weather in order to improve cooling efficiency.

MAX A/C: Press for maximum cooling. The driver and passenger settings set to LO, recirculated air flows through the instrument panel vents, air conditioning turns on and the fan adjusts to the highest speed.

DUAL: Press to switch on temperature control for the passenger side of the vehicle.

Climate controlled seats: Press to switch the climate controlled seats on and off. See Climate Controlled Seats (page 163).

Fan speed control: Adjusts the volume of air circulated in the vehicle.

Heated rear window: Press to switch the heated rear window on and off. See Heated Rear Window (page 152).

Driver temperature control: Adjusts the temperature setting on the driver side. This control also adjusts the passenger side temperature when you switch off dual zone mode.

When dual zone is off, passenger temperature settings remain the same as the driver settings.

Passenger temperature control: Adjusts the temperature setting on the passenger side.

A/C: Press to switch the air conditioning on or off. Use A/C with recirculated air to improve cooling performance and efficiency.

Note: In certain conditions (for example, maximum defrost), the air conditioning compressor may continue to operate even though you switch off the air conditioning.

Heated seats: Press to switch the heated seats on and off. See Heated Seats (page 162).

Note: Prolonged use of recirculated air may cause the windows to fog up.

Note: You may feel a small amount of air from the footwell air vents regardless of the air distribution setting.

Note: To reduce humidity build-up inside your vehicle, do not drive with the system switched off or with recirculated air always switched on.

Note: Do not place objects under the front seats as this may interfere with the airflow to the rear seats.

Note: Remove any snow, ice or leaves from the air intake area at the base of the windshield.

Note: To improve the time to reach a comfortable temperature in hot weather, drive with the windows open until you feel cold air through the air vents.

149

Note: To reduce fogging of the windshield during humid weather, adjust the air distribution control to the windshield air vents position.

Note: Adjusting the settings when your vehicle interior is extremely hot or cold is not necessary. The system automatically adjusts to heat or cool the interior to your selected temperature as quickly as possible. For the system to function efficiently, the instrument panel and side air vents should be fully open.

Note: If you select AUTO during cold temperatures, the system directs airflow to the windshield and side window vents. In addition, the fan may run at a slower speed until the engine warms up.

Note: If you select AUTO during hot temperatures and the inside of the vehicle is hot, the system automatically uses recirculated air to maximize interior cooling. Fan speed may also reduce until the air cools.

Equipped)

Press the button to clear the rear window of thin ice and fog. The heated rear window turns off

after a short period of time.

Note: Make sure the engine is on before operating the heated windows.

Note: Do not use razor blades or other sharp objects to clean or remove decals from the inside of the heated rear window. The vehicle Warranty may not cover damage caused to the heated rear window grid lines.

When you switch the heated rear window on, the heated exterior mirrors turn on.

Note: Do not remove ice from the mirrors with a scraper or adjust the mirror glass when it is frozen in place.

Note: Do not clean the mirror housing or glass with harsh abrasives, fuel or other petroleum-based cleaning products.

Your vehicle is equipped with a cabin air filter, which gives you and your passengers the following benefits:

It improves your driving comfort by reducing particle concentration.

It improves the interior compartment cleanliness.

It protects the climate control components from particle deposits.

You can locate the cabin air filter behind the glove box.

Note: Make sure you have a cabin air filter installed at all times. This prevents foreign objects from entering the system. Running the system without a filter in place could result in degradation or damage to the system.

Replace the filter at regular intervals. See

Scheduled Maintenance (page 581).

For additional cabin air filter information, or to replace the filter, see an authorized dealer.
