Operating Tips
The following tips will help you to get the most
satisfaction from your heater system.
In humid weather, select V before starting
your engine. This will help to prevent
windshield fogging. After a few minutes, you
may select another airflow position.
To prevent humidity buildup inside your
vehicle, always drive with the heater system
turned on.
Do not put objects under the front seats that
interfere with the flow of air to the back seat
area.
Remove any snow, ice, or leaves from the air
intake area at the bottom of the windshield.
For maximum heating, rotate the function
selector knob to FLR, the temperature control
knob to the red (warm) range, and the fan
blower knob to HI.
Auxiliary Heater and Air
Conditioner (If equipped)
If your vehicle is equipped with a factory
installed auxiliary unit (heater or heater/air
conditioner), the front control assembly will
include separate switches for FRONT and REAR
fan control. Fan speed for front and rear systems
can be set as desired by adjusting these switches.
