damage the rear defogger.
Repairs would not be covered by
the vehicle warranty.
Rear Heating System
If equipped, the rear heating system
lets you adjust the amount of air
flowing into the rear of the vehicle,
from the front seating area. This
feature works with the main climate
control system in the vehicle.

For vehicles with a rear climate
control panel, it is located overhead
behind the driver and front
passenger, centered in front of the
second row. To adjust the rear
climate control panel settings by a
rear seat passenger, the front
climate control panel fan knob must
be in the AUX position. The fan
speed, air delivery mode, and
temperature can then be adjusted. AUX :
Turn the fan knob on the
front climate control panel to AUX to
let rear seat passengers use the
control panel in the rear seating
area. This disables the front control
panel. To return control to the front
panel, move the fan knob out
of AUX.
9: Turns the system off.
9:Turn clockwise or
counterclockwise to increase or
decrease the fan speed in the rear
seating area. Temperature Control :
Turn
clockwise or counterclockwise to
increase or decrease the
temperature in the rear
seating area.
The air conditioning system on the
main climate control panel must be
turned on to direct cooled air to the
rear of the vehicle. If it is not on,
then the temperature in the rear of
the vehicle remains at cabin
temperature.
Air Delivery Mode Control : Turn
clockwise or counterclockwise to
change the direction of the airflow in
the rear seating area.
To change the current mode, select
one of the following:
H: Air is directed to the upper
outlets, with some directed to the
floor outlets.
2: Air is directed to the floor
outlets.
Be sure to keep the area under the
front seats clear of any objects so
that the air inside of the vehicle can
circulate effectively.

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.
. Use of non-GM approved hood
deflectors may 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.
Maintenance
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.

172 Driving and Operating
.Antilock Brake System (ABS)
improves vehicle stability during
hard stops, but the brakes
should be applied sooner than
when on dry pavement. See
Antilock Brake System (ABS)
0190.
. Allow greater following distance
and watch for slippery spots. Icy
patches can occur on otherwise
clear roads in shaded areas.
The surface of a curve or an
overpass can remain icy when
the surrounding roads are clear.
Avoid sudden steering
maneuvers and braking while
on ice.
. Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place and
signal for help. Stay with the vehicle
unless there is help nearby.
If possible, use Roadside
Assistance. See Roadside
Assistance Program 0319. To get
help and keep everyone in the
vehicle safe: .
Turn on the hazard warning
flashers.
. Tie a red cloth to an outside
mirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
. Clear snow from the base of
the vehicle, especially any
blocking the exhaust pipe.
. Open a window about 5 cm
(2 in) on the vehicle side
that is away from the wind,
to bring in fresh air.
. Fully open the air outlets on
or under the instrument
panel.
(Continued)
Warning (Continued)
.Adjust the climate control
system to circulate the air
inside the vehicle and set
the fan speed to the highest
setting. See “Climate
Control Systems.”
For more information about CO,
see Engine Exhaust 0185.
To save fuel, run the engine for
short periods to warm the vehicle
and then shut the engine off and
partially close the window. Moving
about to keep warm also helps.
If it takes time for help to arrive,
when running the engine, push the
accelerator pedal slightly so the
engine runs faster than the idle
speed. This keeps the battery
charged to restart the vehicle and to
signal for help with the headlamps.
Do this as little as possible, to
save fuel.
