Climate Controls 8-3
Manual Operation
O (Power): Press to turn the
climate control system on or off.
When the climate control system is
turned off the air inlet defaults to
outside air.
D C (Fan Control): Press the
buttons to increase or decrease the
fan speed. Pressing either button
cancels automatic fan control.
Press AUTO to return to automatic
operation. The blower may reduce
during an Onstar
®
session to limit
background noise.
If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air
filter might need to be replaced. For
more information, see Passenger
Compartment Air Filter on page 8‑7
and Scheduled Maintenance on
page 11‑2.
H G (Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y (Vent): Air is directed to the
instrument panel outlets.
\ (Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In
automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[ (Floor): Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
- (Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor,
and side window outlets. When
this mode is selected, the system
turns off recirculation and runs the
air-conditioning compressor unless
the outside temperature is at or
below freezing. If recirculation is
selected while in defog mode, it is
cancelled after 10 minutes.
0 (Defrost): This mode clears
the windshield of fog or frost
more quickly. Air is directed to the
windshield, with some air directed
to the side windows. In this mode,
the system automatically turns
off recirculation and runs the
air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
