On cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best if you keep your
windows closed while using it.

If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.

If you see lines running across the rear windows, you
have a rear window defogger. The lines warm the glass.

For best results, clear the windows of as much snow or
ice as possible before using the rear window defogger.

To turn on the rear window
defogger, press this button
near the fan control. An
indicator light in the button
will come on when the 
rear window defogger 
is working.

The rear window defogger will only work when the
ignition is in RUN.

The rear window defogger will turn itself off after
several minutes. If you need additional warming time,
press the button again. Pressing the button when the
indicator light is illuminated will turn the defogger off.

If your vehicle is equipped with heated outside rearview
mirrors, the rear window defogger button will activate
both the rear window defogger and the heated outside
rearview mirrors. See “Heated Outside Rearview
Mirrors” in the Index.
