Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<
(Rear Window Defogger): Press this button
to turn on the rear window defogger. It will
automatically turn off several minutes after it has
been activated. The defogger can also be
turned off by pressing the button again or by
turning off the engine. Do not drive the vehicle until
all the windows are clear.
If your vehicle has heated outside rearview
mirrors, the mirrors will heat to help clear fog or
frost from the surface of the mirror when the
rear window defog button is pressed.
Notice: Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the air outlets located in the center and on the
side of your instrument panel to direct the airflow.
Operation Tips
•
Keep the hood and front air inlets free of ice,
snow, or any other obstruction (such as
leaves). The heater and defroster will work far
better, reducing the chance of fogging the
inside of your windows.
•
When you enter a vehicle in cold weather,
press the fan up button to the maximum
fan level before driving. This helps clear the
intake ducts of snow and moisture, and
reduces the chance of fogging the inside of
your window.
•
Keep the air path under the front seats clear
of objects. This helps air to circulate
throughout your vehicle.
•
Adding outside equipment to the front of your
vehicle, such as hood-air deflectors, may
affect the performance of the heating and air
conditioning system. Check with your
dealer before adding equipment to the outside
of your vehicle.
