1.Fan speed adjustment:Controls the volume of air circulated in the
vehicle.
2.Temperature selection:Controls the temperature of the airflow in
the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Distributes recirculated air through the instrument panel
vents only to cool the vehicle. This re-cooling of the interior air is more
economical and efficient. Recirculated air may also help reduce
undesirable odors from entering the vehicle.
:Distributes air through the instrument panel vents.
:Distributes air through the instrument panel vents and the floor
vents.
O (OFF):Outside air is shut out and the fan will not operate.

any other airflow selection except defrost. Recirculation may turn off
automatically in all airflow selections except MAX A/C.
5.A/C:Press to activate/deactivate air conditioning. Use with

Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle, do not drive with the
air flow selector in the O (OFF) position.
•Do not put objects under the front seats that will interfere with the
airflow to the rear seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2–3 minutes after start up or until the vehicle has been “aired out.”
For maximum cooling performance (MAX A/C) in MAX A/C mode:
•Move the temperature control to the coolest setting.
•Set the fan to the highest speed initially, then adjust in order to
maintain comfort.
To aid in side window defogging and demisting in cold weather:
1. Select
.
2. Select A/C.
3. Set the temperature control to maintain comfort.
4. Set the fan speed to highest setting.
5. Direct the outer instrument panel vents towards the side windows.
