GMC 15919282 Automobile User Manual


 
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 flow. Use the thumbwheel
near the outlet to control the amount
of air flow or to shut off the airflow.
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 flow of air into the
vehicle.
Use of non-GM approved hood
deflectors 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.
