If your vehicle has air conditioning, your heating/air
conditioning controls will look like this:
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
(Temperature Control):Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
A/C (Air Conditioning):This setting will begin to cool
and dehumidify the air inside of your vehicle.
MAX A/C (Maximum Air Conditioning):Turn the right
knob to MAX A/C for maximum cooling. This setting
cools the air the fastest, by recirculating the inside air.Rear Heating System
Your vehicle may have an optional rear heating system
that allows you to adjust the amount of airflowing into
the rear of the vehicle, from the front-seating area.
This feature works with the main climate-control system
in your vehicle.
AUX (Auxiliary Heating System):The thumbwheel for
this system is located to the right of the audio system.
9(Fan):Turn the thumbwheel up or down to increase
or decrease the amount of heated air sent to the
rear-seating area.

to change the direction of the airflow in the
rear-seating area.

outlets, with a little air directed to thefloor outlets.
2(Floor):Use this mode to direct most of the air to
thefloor outlets.
Selecting the Fan Speed
9
(Fan):Turn the left knob clockwise or
counterclockwise to HIGH, MED (Medium) or LOW to
increase or decrease the fan speed in the rear-seating
area. Turn the knob to OFF to turn off the fan.
Setting the Temperature
To increase or decrease the temperature for the rear
of the vehicle, use the right knob located on the
climate-control panel.
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 will remain at cabin temperature.
Be sure to keep the area under the front seats clear of
any objects so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system, seeClimate Control System on page 3-17
listed previously in this section. For information
on ventilation, see“Outlet Adjustment”listed later
in this section.

Rear Window Defogger
Press this button to turn the rear window defogger on or
off. Be sure to clear as much snow from the window
as possible.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window and will only
work when the ignition is RUN.
The rear window defogger will turn off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice:Don’t use a razor blade or something else
sharp on the inside of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.
Outlet Adjustment
Use the outlets located
near the center and on the
sides of the instrument
panel to change the
direction of airflow.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block theflow of air into your 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 your vehicle more
effectively.

system, this light will come
on when you start your
engine and may stay on
for several seconds.

have anti-lock brakes. If the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light”earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If
the light doesn’t come on then, have itfixed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area your engine is
too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
operating conditions, you should pull off the road,
stop your vehicle, and turn off the engine as soon
as possible.
