Sensors
The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor or
the system will not work properly.
There is also an exterior temperature
sensor 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 outlet temperature, fan
speed, and 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.
Air Vents
Adjustable air vents are in the center
and on the sides of the instrument
panel, and on the rear of the center
console storage.
Move the slider knobs to change the
direction of or to close off the airflow.
CLIMATE CONTROLS
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.
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.
