Rear Window Defogger
The rear window defogger uses a warming
grid to remove fog from the rear window.
: 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 0 24.
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 0 112.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Afterblow Feature
If equipped, under certain conditions, the
fan may stay on or may turn on and off
several times after you turn off and lock the
vehicle. This is normal.
Climate Controls
Air Vents
Use the louvers located on the air vents to
change the direction of the airflow.
To open or close off the airflow:
On the center air vents, move the slider
knobs up or down.
On the outer and rear air vents, move the
slider knobs right or left.
Operation Tips
Clear away any ice, snow, or leaves from
air inlets at the base of the windshield
that could block the flow of air into the
vehicle.
Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle, which may
improve long term system performance.
Keep the path under the front seats clear
of objects to help circulate the air inside
of the vehicle more effectively.
Use of non-GM approved hood deflectors
can adversely affect the performance of
the system. Check with your dealer
before adding equipment to the outside
of the vehicle.
