Heating If you have the standard system, on cold days use FLOOR with the temperature knob in the red area. If you have the electronic system, press AUTO and adjust the temperature by turning the TEMP knob up or down. You may also adjust the electronic system manually by pressing the MODE button and selecting FLOOR. Again, adjust the temperature by turning the TEMP knob up or down. With either system, outside air will be heated and sent through the floor outlets. The heater works best if you keep your windows closed while using it. 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 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 control toward high. If you have the electronic system and select FRONT defrost or DEFOG from AUTO, the system will control the fan speed. Adjust the temperature and fan speed to your comfort level. 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. 3-9

Heating
If you have the standard system, on cold days use
FLOOR with the temperature knob in the red area. If
you have the electronic system, press AUTO and adjust
the temperature by turning the TEMP knob up or down.
You may also adjust the electronic system manually by
pressing the MODE button and selecting FLOOR.
Again, adjust the temperature by turning the TEMP
knob up or down.
With either system, outside air will be heated and sent
through the floor outlets. The heater works best if you
keep your windows closed while using it.
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 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 control
toward high.
If you have the electronic system and select FRONT
defrost or DEFOG from AUTO, the system will control
the fan speed. Adjust the temperature and fan speed to
your comfort level. 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.
