Mirrors036.
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.

Heated and Ventilated Front
Seats 053, and Heated
Steering Wheel 0110.Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar
intensity.
The climate control system
uses the sensor information to
adjust the temperature, fan
speed, recirculation, and air
delivery mode for best
comfort. If the sensor is covered, the
automatic climate control
system may not work properly.
Afterblow Feature

conditions, the fan may stay

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.
.Clear snow off the hood to
improve visibility and help
decrease moisture drawn
into the vehicle.
.Keep the path under the
front seats clear of objects
to help circulate the air
inside of 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
0425.
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.
During service, all refrigerants
should be reclaimed with
proper equipment. Venting
refrigerants directly to the
atmosphere is harmful to the
environment and may also
create unsafe conditions
based on inhalation,
combustion, frostbite, or other
health-based concerns.
The air conditioning system
requires periodic maintenance.
See Maintenance Schedule
0 425.

and seating positions. The
combined weight of the
driver, passengers, and
cargo should never exceed
the vehicle's capacity
weight.
Certification/Tire Label
Label Example
A vehicle-specific
Certification/Tire label is
attached to the center
pillar (B-pillar).
The label may show the
size of the vehicle's original
tires and the inflationpressures needed to obtain
the gross weight capacity
of the vehicle. The label
shows the gross weight
capacity of the vehicle. This
is called the Gross Vehicle
Weight Rating (GVWR). The
GVWR includes the weight
of the vehicle, all
occupants, fuel, and cargo.
The Certification/Tire label
may also show the
maximum weights for the
front and rear axles, called
the Gross Axle Weight
Rating (GAWR). To find out
the actual loads on the
front and rear axles, weigh
the vehicle at a weigh
station. Your dealer can
help with this. Be sure to
spread the load equally on
both sides of the
centerline.
Caution
Overloading the vehicle may
cause damage. Repairs
would not be covered by the
vehicle warranty. Do not
overload the vehicle.
{Warning
Things inside the vehicle
can strike and injure
people in a sudden stop
or turn, or in a crash.
.Put things in the cargo
area of the vehicle. In
the cargo area, put
them as far forward as
possible. Try to spread
the weight evenly.
.Never stack heavier
things, like suitcases,
inside the vehicle so
that some of them are
above the tops of the
seats.
