Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed,
and after five minutes each additional time the button
is pressed. You can turn the defogger off by pressing
the button again or turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
NOTICE:
Don’t use a razor blade or anything 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.

cooling is needed, use UPPER to direct outside air
through your vehicle. Your vehicle also has the
flow
- through ventilation system.
Your vehicle’s flow - through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
