Rear Window Defogger
Manual System
Automatic System
Press the REAR button (the indicator light will glow) to
warm the defogger grid on the rear window. The engine
must be running for the defogger grid to warm up.
The system will turn off automatically after about
10 minutes of use. If you turn it on again, the defogger
will operate for about five minutes. You can also turn
the defogger off by turning the ignition to OFF or
by pressing the button again. The indicator light will
turn off.
If your vehicle has heated outside rearview mirrors,
the outside mirrors will also defrost when you press
this button.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or something else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn’t be covered by your warranty.
