Rear Window Defogger

defogger, a warming grid is used to
remove fog or frost from the rear
window.
It only works when the ignition is
in ON/RUN.

Press to turn the rear window
defogger on or off.
The rear window defogger turns off
several minutes after the button is

defogger will run for several more
minutes before turning off. The
defogger can also be turned off by
turning off the engine.

windows are clear.

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.
