Climate Controls  
Remote Start Climate Control Operation :  
If equipped with remote start, the climate  
control system may run when the vehicle is  
started remotely. If equipped with heated or  
ventilated seats or a heated steering wheel,  
these features may come on during a  
remote start. See Remote Vehicle Start 0 18,  
Heated and Ventilated Front Seats 0 49, and  
Heated Steering Wheel 0 100.  
The climate control system uses the sensor  
information to adjust the temperature, fan  
speed, recirculation, and air delivery mode  
for best comfort.  
To close the rear A/C vents, move the  
sliding knobs to the full inboard position.  
Operation Tips  
.
.
.
.
Clear away any ice, snow, or leaves from  
air inlets at the base of the windshield  
that could block airflow.  
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 system performance.  
Check with your dealer before adding  
equipment to the outside of the vehicle.  
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.  
Sensors  
Air Vents  
Use the sliding knobs on the center and side  
air vents to change the direction of the  
airflow.  
.
Do not attach any devices to the air vent  
slats. Doing so restricts airflow and may  
cause damage to the air vents.  
Air vents blow warm air on the side  
windows in cold weather. If Floor, Defog,  
or Defrost modes are selected, a small  
amount of air will come from the vents  
closest to the window.  
Maintenance  
Passenger Compartment Air Filter  
The filter reduces the dust, pollen, and other  
airborne irritants from outside air that is  
pulled into the vehicle.  
The solar sensor, on top of the instrument  
panel near the windshield, monitors the  
solar heat.  
To close the front A/C vents, move the  
sliding knobs to the full down position for  
vertical slats or away from you for  
horizontal slats.

Service  
All vehicles have a label underhood that  
identifies the refrigerant used in the vehicle.  
The refrigerant system should only be  
serviced by trained and certified technicians.  
The air conditioning evaporator should never  
be repaired or replaced by one from a  
salvage vehicle. It should only be replaced  
by a new evaporator to ensure proper and  
safe operation.  
During service, all refrigerants should be  
reclaimed with proper equipment. Venting  
refrigerants directly to the atmosphere is  
harmful to the environment and may also  
create unsafe conditions based on  
inhalation, combustion, frostbite, or other  
health-based concerns.  
The air conditioning system requires periodic  
maintenance. See Maintenance Schedule  
0 417.
