Defogging and Defrosting On cool, humid days, use defog to keep the windshield and side windows clear. Use FRONT defrost to remove fog or ice from the windshield quickly in extremely humid or cold conditions. If you have the standard system, select defog and adjust the temperature and fan speed to your comfort level. Turn the A/C on to help dehumidify the air. Use FRONT defrost with the temperature toward the red area and the fan speed toward high. If you have the electronic system and select FRONT defrost or defog from AUTO, the system will control the fan speed. After the windshield is clear, adjust the temperature to your normal setting and select the AUTO button and return to AUTO mode and fan control. For maximum FRONT defrost performance under extreme icing or frosting conditions, increase the temperature setting to 90_F (33_C) and increase the fan speed to high. Rear Window Defogger The lines you see on the rear window warm the glass. Press the button to start warming your window. A light will glow in the button while the defogger is working. If your vehicle is equipped with heated mirrors, this button will activate them. After 10 minutes the system will turn off by itself, or press the button during the heating cycle to turn it off. If you need additional warming time, push the button again. The system will then operate for five minutes before turning off by itself. If your speed is maintained over 30 mph (48 km/h), the rear defog will not turn off automatically to help keep the rear glass clear. 3-8

Defogging and Defrosting
On cool, humid days, use defog to keep the windshield
and side windows clear. Use FRONT defrost to remove
fog or ice from the windshield quickly in extremely
humid or cold conditions.
If you have the standard system, select defog and adjust
the temperature and fan speed to your comfort level.
Turn the A/C on to help dehumidify the air. Use FRONT
defrost with the temperature toward the red area and the
fan speed toward high.
If you have the electronic system and select FRONT
defrost or defog from AUTO, the system will control the
fan speed.
After the windshield is clear, adjust the temperature to
your normal setting and select the AUTO button and
return to AUTO mode and fan control.
For maximum FRONT defrost performance under
extreme icing or frosting conditions, increase the
temperature setting to 90
F (33
C) and increase
the fan speed to high.
Rear Window Defogger
The lines you see on the rear window warm the glass.
Press the button to start
warming your window.
A light will glow in the
button while the defogger
is working.
If your vehicle is equipped with heated mirrors, this
button will activate them.
After 10 minutes the system will turn off by itself, or
press the button during the heating cycle to turn it off.
If you need additional warming time, push the button
again. The system will then operate for five minutes
before turning off by itself. If your speed is maintained
over 30 mph (48 km/h), the rear defog will not turn off
automatically to help keep the rear glass clear.
