The airflow direction and temperature can be adjusted.
Temperature Control: Turn clockwise or
counterclockwise to increase or decrease the
temperature.
9(Fan Control): Turn clockwise or counterclockwise
to increase or decrease the fan speed. The fan speed
is temporarily reduced between the transition to a new
mode. The fan will resume when the new mode is
complete.
If the airflow seems low when the fan speed is at the
highest setting, the passenger compartment air filter
may need to be replaced. For more information, see
Passenger Compartment Air Filter
on page 4‑25and
Scheduled Maintenance on page 7‑3.
Air Delivery Mode Control: Turn clockwise or
counterclockwise to change the direction of the airflow
in the vehicle.
To change the current mode, select one of the following:
H(Vent): Air is directed to the instrument panel
outlets.

Outlet Adjustment
Use the levers, located in the middle of the front
outlets, to change the direction of the airflow. Use the
thumbwheel located between the outlets to turn them on
and off.
If the vehicle has rear seat outlets, adjust the direction
of the airflow using the lever in the center of each outlet.
Operation Tips
.Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could 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 the front seats clear of
objects to help circulate the air inside the vehicle
better.
Passenger Compartment Air Filter
Outside air is routed through a passenger compartment
air filter before entering the vehicle. This filter removes
certain particles from the air, including pollen and dust
particles. The filter should be replaced as part of routine
scheduled maintenance. SeeScheduled Maintenance
on page 7‑3for when to replace the filter. The access panel for the passenger compartment air
filter is located under the hood near the windshield, on
the passenger's side of the vehicle.
To access the passenger compartment air filter, do the
following:
1. Press the tabs back and left to remove the cover.
2. Insert a tool behind the push pin located on the inboard side of the air filter compartment to
carefully pry the pin out.
