The interior temperature sensor
located on the instrument panel to
the right of the steering column,
measures the temperature of the
air inside the vehicle.
There is also an exterior
temperature sensor located
behind the front grille. This sensor
reads the outside air temperature
and helps maintain the temperature
inside the vehicle. Any cover on the
front of the vehicle could cause a
false reading in the displayed
temperature.The climate control system uses
the information from these sensors
to maintain comfort settings by
adjusting the temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle facing
the sun. The recirculation mode will
also be used as needed to maintain
cool outlet temperatures.
Outlet Adjustment
Use the slider switch in the center of
the outlet, to change the direction of
the air ow. Use the thumbwheel
near the outlet to control the amount
of air ow or to shut off the air ow.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips
Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the ow of air into
the vehicle.
Use of non-GM approved hood
de ectors can adversely affect
the performance of the system.
Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle
more effectively.
If fogging reoccurs while in
vent or bi-level modes with mild
temperature throughout the
vehicle, turn on the air conditioner
to reduce windshield fogging.
