Heating
The heater works best if you keep your windows closed
while using it. On cold days, use floor mode with the
temperature knob turned clockwise. Blend mode is
useful in cool weather when you have fog or ice on the
windshield or side windows.
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.
Defogging and Defrosting
On cool, humid days, use blend mode to keep the
windshield and side windows clear.
Use defrost mode to remove fog or ice from the
windshield quickly in extreme humid or cold conditions.
Turn the temperature knob clockwise and move the fan
knob toward high.
Rear Window Defogger (If Equipped)
If your vehicle has this
feature, the rear window
will have lines that warm
the glass.
For best results, clear the window of as much snow or
ice as possible before using the rear window defogger.
To turn on the rear window defogger, find the button
marked REAR with the defog symbol on the lower right
corner of your climate control system. Press the button
until the light in the button comes on, then release it. It
will only work if the ignition switch is turned to RUN.
Pressing the REAR button on your climate control
system will also activate your heated outside mirrors
(if equipped). This will help to keep ice and snow from
collecting on your mirror surfaces.
