190 Climate Controls
The climate control system uses the sensor
information to adjust the temperature, fan
speed, recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise the
automatic climate control system may not
work properly.
Afterblow Feature
If equipped, under certain conditions, the
fan may stay on or may turn on and off
several times after you turn off and lock the
vehicle. This is normal.
Air Vents
Use the sliding knobs on the center and side
air vents to change the direction of the
airflow.
Air vents blow warm air on the side
windows in cold weather. If Floor, Defog,
or Defrost modes are selected, a small
amount of air will come from the vents
closest to the window.
To close the front A/C vents, move the
sliding knobs to the full down position for
vertical slats or away from you for
horizontal slats.To close the rear A/C vents, move the
sliding knobs to the full inboard position.
Operation Tips
.Clear away any ice, snow, or leaves from
air inlets at the base of the windshield
that could block airflow.
.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 system performance.
Check with your dealer before adding
equipment to the outside of the vehicle.
.Do not attach any devices to the air vent
slats. Doing so restricts airflow and may
cause damage to the air vents.
Maintenance
Passenger Compartment Air Filter
The filter reduces the dust, pollen, and other
airborne irritants from outside air that is

The filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule
0388. To find out
what type of filter to use, see Maintenance
Replacement Parts 0393.

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
0 388.

Loading Points
1. Primary Load Points
2. Secondary Load Areas
3. GM Approved Accessory MountingPoints
Structural members (1) and (2) are included
in the pickup box design. Additional
accessories should use these load points.
Depending on the accessory design, use a
spacer under the accessory at the load
points to remove gap. The holes for GM
approved accessories (3) are not intended for
aftermarket equipment. See
www.gmupfitter.com for additional pickup
box load bearing structural information.
Truck-Camper Loading Information
A vehicle-specific Truck-Camper Loading
Information label is attached to the
inside of the vehicle's glove box. This
label indicates if a slide-in camper can
be carried, how much of a load the
vehicle can carry, and how to correctly
spread out the load. It will help to
match the right slide-in camper to the
vehicle.
Your dealer can help make a good
vehicle-camper match and help
determine the Cargo Weight
Rating (CWR).
When installing and loading a slide-in
camper, check the manufacturer's
instructions.
When carrying a slide-in camper, the
total cargo load of the vehicle is the
weight of the camper plus:
.Everything added to the camper after
it left the factory.
.Everything in the camper.
.All the people inside. The CWR is the maximum weight of the
load the vehicle can carry. It does not
include the weight of the people inside.
But, use about 68 kg (150 lb) for
each seat.
The total cargo load must not be more
than the vehicle's CWR.
Refer to the Truck-Camper Loading
Information label in the glove box for
dimensions A and B as shown in the
following illustration.
Use the rear edge of the load floor for
measurement purposes. The
recommended location for the cargo
center of gravity is in zone C for the
CWR. It is the point where the mass of
