The recirculation mode is cancelled when the
system enters the defog mode. If recirculation is
selected while in the defog mode, it is cancelled
after 10 minutes.
If there is fogging on the side windows, remain in
defog or defrost mode until they clear.
0(Defrost): Press this button to direct most of
the air to the windshield, with some air directed
to the side windows and outboard panel outlets. In
this mode, the system automatically turns off
recirculation and runs the air-conditioning
compressor, unless the outside temperature is at
or below freezing. Recirculation cannot be
selected while in the defrost mode.
This mode can also cause the fan speed and air
temperature to increase.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger only works when the
ignition is on or during remote start, if
programmed. See “Personal Settings Menu” under
Vehicle Personalization on page 148 for additional
information.
=(Rear Window Defogger): Press this button
to turn the rear window defogger on or off. Be
sure to clear as much snow from the rear window
as possible.
The rear window defogger turns off about
10 minutes after the button is pressed. If the
vehicle’s speed is above 30 mph (48 km/h), the
rear defogger stays on continuously. If turned
on again, the defogger only runs for about
five minutes before turning off. The defogger can
also be turned off by pressing the button again
or by turning off the engine.
The heated outside rearview mirrors also heat to
help clear fog or frost from the surface of the
mirror when the rear window defogger is on. See
Outside Power Heated Mirrors on page 130.
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.
