the remote start feature, the climate control
system may run when the vehicle is started
remotely. The system uses the driver’s
previous settings to heat or cool the inside
of the vehicle. The rear defog may come on

Sensors
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.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Air Vents
Use the louvers located on the air vents to
change the direction of the airflow.
To open or close off the airflow:
.Move slider knobs away from the
occupant for shut off closing.
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.
.Do not attach any devices to the air vent
slats. This restricts airflow and may cause
damage to the air vents.
Caution
Use of air fresheners may cause
permanent damage to plastics and
painted surfaces. If an air freshener
comes in contact with any plastic or
painted surface in the vehicle, blot
immediately and clean with a soft cloth
dampened with a mild soap solution.
Damage caused by air fresheners would
not be covered by the vehicle warranty.
