Operation Tips
• Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that may
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.
• When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when driving
through a long tunnel with poor ventilation. However,
extended usage of this mode in cold or cool weather
can cause window fogging.
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 may be or 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 may be or 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 may
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.
