Operating Tips
The following tips help you get the most
satisfaction from your air conditioner and heater
system:
In humid weather, select V before starting
your engine. This helps prevent windshield
fogging. After a few minutes of operation,
you may select another airflow position.
To prevent humidity buildup inside your
vehicle, always drive with the air conditioner
and 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
knob to HI.
