MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
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:Uses recirculated air to cool the vehicle. Air flows from the
instrument panel vents only. This mode will help prevent unpleasant
odors from entering the vehicle.
NORM A/C:Uses outside air to cool the vehicle. Air flows from the
instrument panel vents only.
VENT: Distributes outside air through the instrument panel vents.
OFF: Outside air is shut out and the fan will not operate.
FLOOR: Distributes outside air through the floor vents.
MIX: Distributes outside air through the windshield defroster vents, floor
vents and side window demisters.
:Distributes outside air through the windshield defroster vents and
the side window demisters.
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 OFF or MAX A/C position.
•Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to “breathe” using the outside air inlet vents.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
