enough. For the best results, turn the temperature knob
to the middle position, and then adjust it for comfort.

temperature is 35 _ F (2 _ C) or colder. You may notice

until the engine is warmed up. This is a normal
condition designed to provide heat to the passenger
compartment and defrost the windows more quickly.

Defogging and Defrosting

To rapidly defrost the windshield, turn the temperature
knob all the way clockwise (to the red area) and turn
the mode knob to DEFROST. Adjust the fan to the
highest speed.
To keep the windshield clear and bring in heated air
through the heater ducts, turn the mode knob to DEFOG.
When the temperature outside is above freezing, the air
conditioner compressor will run in these settings to help
remove moisture from the air.
Your vehicle is equipped with side window defogger
vents located on the top of the instrument panel. For
additional side window defogging, turn the mode knob
-
to the BI LEVEL setting and adjust the fan to the
highest speed. Aim the side vents on the instrument
panel toward the side windows. For increased airflow
to the side vents, close the center vents.
Operating the HVAC system in the RECIRCULATION
mode may cause fogging of the vehicle's windows when
the weather is cold and damp. To clear the fog, switch
the HVAC system to either the DEFOG or DEFROST
mode and increase the fan speed. To avoid re
of the windows, operate the HVAC system in the
OUTSIDE AIR mode.
For additional information, refer to "RECIRCULATION"
earlier in this section.
