AUTO position.
The current set temperature displays. When AUTO
is selected, the air conditioning operation and air
inlet is automatically controlled. The air conditioning
compressor runs while the outside temperature is
over about 40°F (4°C). The air inlet will normally be
set to outside air. If it is hot outside, the air inlet
may automatically switch to recirculate inside air to
help quickly cool down the vehicle.
2. Set the temperature.
An initial setting of 73°F (23°C) is recommended.
Allow about 20 minutes for the system to regulate.
Press
worxto adjust the temperature setting
as necessary. If the temperature is set at 60°F
(15°C) the system remains at the maximum cooling
setting. If the temperature is set at 90°F (32°C)
the system remains at the maximum heat setting.
Choosing either maximum setting does not
cause the vehicle to heat or cool any faster.Do not to cover the sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on the intensity
of the sun.
Also do not cover the sensor grille on the lower
right side of the climate control faceplate, as
this regulates the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan
until warm air is available. The length of delay
depends on the engine coolant temperature. Turning
the fan knob overrides this delay and changes
the fan to the selected speed.

Operation Tips
•Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that can
block the flow of air into the vehicle.
•Do not use non-GM approved hood deflectors as
they could adversely affect the performance of
the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle’s functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.
