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.

The filter should be replaced as part of

routine scheduled maintenance. See

Maintenance Schedule 0 417. To find out

what type of filter to use, see Maintenance

Replacement Parts 0 422.

3. Press the sides of the glove box door

inward and rotate the door downward to

remove.

2. Push the dampener arm to the left until

it releases the glove box.

4. Pull lever on left side of the filter door

and slide left, then remove the door.

Remove the old filter.

1. Open the lower glove box door

completely.

5. Install the new air filter.

6. Reinstall the filter door.

7. Reverse the steps to reinstall the

glove box.

See your dealer if additional assistance is

needed.

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.
