8-8 Climate Controls
@(Recirculation):Press to
alternate between recirculating air
inside the vehicle or pulling in
outside air. The indicator light on the
button is lit when recirculation mode
is active. This helps to quickly cool
the air inside the vehicle or reduce
the outside air and odors that may
enter.
Pressing this button cancels
automatic recirculation. Press AUTO
to return to automatic operation;
recirculation runs automatically as
needed.
Manual recirculation mode is not
available when in Defrost or Defog
modes.
Auto Defog: The climate control
system may have a sensor to
automatically detect high humidity
inside the vehicle. When high
humidity is detected, the climate
control system may adjust to
outside air supply and turn on the
air conditioner. If the climate control
system does not detect possible
window fogging, it returns to normal operation. To turn Auto Defog off or
on, see
“Climate and Air Quality”
under Vehicle Personalization on
page 5-44.
Rear Window Defogger
=REAR (Rear Window
Defogger): Press to turn the rear
window defogger on or off. An
indicator light on the button comes
on to show that the rear window
defogger is on.
The upper gridlines on the rear
window are antenna lines and are
not intended to heat when the
defogger is activated.
The heated outside mirrors turn on
when the rear window defogger
button is on. They help to clear fog
or frost from the surface of the
mirrors.
The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization on
page 5-44. When auto rear defog is
selected, the rear window defogger turns on automatically when the
interior temperature is cold and the
outside temperature is about 4°C
(40°F) and below. The auto rear
defogger turns off automatically.{Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.

Move the slats (2) to change the
direction of the airflow.
Additional air vents are beneath the
windshield and the driver side and
passenger side door windows.
These are fixed and cannot be
adjusted.Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside the
vehicle more effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
.Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See
Maintenance Schedule on
page 11-3.
See your dealer regarding
replacement of the filter.
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.
