A(Floor):This mode directs most of the air to the floor
outlets with some air directed to the side windows.
The right knob can also be used to select defog or defrost
modes. Information on defogging and defrosting can be
found later in this section.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
:(Outside Air):Press this button to turn the outside
air mode on or off. When this mode is on, outside air will
circulate throughout your vehicle. The outside air mode
can be used with all modes, but it cannot be used with the
recirculation mode.
?(Recirculation):This mode keeps outside air from
coming in the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or to help heat or
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or off. The
air-conditioning compressor will come on. The
recirculation mode cannot be used with the outside air
mode. Recirculation is not available when in the defog or
defrost modes or when the fan is off.When you switch to the defog or defrost modes the
system will automatically move from recirculation to
outside air. When you move the mode knob back to
another mode, the system will move back into
recirculation. When the car is turned off and back on the
system will default to outside air automatically.
Temperature Control:Turn the center knob clockwise
or counterclockwise to manually increase or decrease
the temperature inside your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-20.
A/C (Air Conditioning):Press this button to turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light in the button will come on to let you
know that air conditioning is activated.
The fan knob must be set to a speed for the air
conditioning to operate.

On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the recirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle is cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to choose from to
clear fog or frost from your windshield. Use thedefog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and most of the remaining air to the
floor outlets with a small amount directed at the side
windows. When you select this mode, the system turns
off recirculation and runs the air-conditioning
compressor unless the outside temperature is at or
below freezing. The recirculation mode cannot be
selected while in the defog mode. Do not drive the
vehicle until all the windows are clear.
1(Defrost):This mode directs most of the air to the
windshield with some air directed to the floor outlets. In
this mode, the system will automatically turn off
recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the
defrost mode.
