A/C :Press to turn the air
conditioning system on or off. An
indicator light comes on to show
that the air conditioning is enabled.

conditioner will not run. The A/C
light will stay on even if the outside
temperatures are below freezing
and the A/C compressor may be off.
@: Press to turn on recirculation.
An indicator light comes on. Air is
recirculated to quickly cool the
inside of the vehicle. It can also be
used to help reduce outside air and
odors that enter the vehicle.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
K: Press to turn the rear window
defogger on or off. An indicator light
on the button comes on to show that
the rear window defogger is on.
The rear window defogger only
works when the ignition is on. The
defogger turns off if the ignition is
turned off or to ACC/ACCESSORY.
Caution
Using a razor blade or sharp
object to clear the inside rear
window can damage the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.
Heated Mirror : If equipped with
heated outside mirrors, the mirrors
heat to help clear fog or frost from
the surface of the mirror when the
rear window defog button is
pressed. See Heated Mirrors 051.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort. The automatic
recirculation mode sensitivity can be adjusted. See
“Air Quality Sensor”
under Vehicle Personalization
0 152.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
