?(Recirculation):This mode keeps outside air from
coming into the vehicle. It can be used to prevent outside
air and odors from entering your vehicle or to help heat or
cool the air inside your vehicle more quickly.
If your vehicle has a recirculation button (uplevel model),
press the button to turn the recirculation mode on.
When the button is pressed, an indicator light in the
button will come on. Press the button again to return to
outside air mode.
If your vehicle has an air intake lever (base model), move
the lever to choose the recirculation mode.
Using the recirculation mode for extended periods may
cause your windows to fog. If this happens, select the
defrost mode.
:(Outside Air):This mode brings outside air into
the vehicle.
If your vehicle has a recirculation button (uplevel
model), press the button until the recirculation mode is
turned off. Your vehicle will then return to outside
air mode.If your vehicle has an air intake lever (base model),
move the lever to choose the outside air mode.
A/C (Air Conditioning):If your vehicle has air
conditioning, follow these steps to use the system. Start
the engine and set the fan control knob to the desired
speed. The air conditioning compressor does not
operate when the fan control knob is in the off position.
Press the A/C button to turn the air conditioning
compressor on and off. When the A/C button is pressed,
an indicator light in the button will come on to let you
know that air conditioning is activated.
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.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Press the A/C button.
4. Select the recirculation mode.
5. Select the coolest temperature.
3-15

Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you may sometimes notice a small amount
of water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
or moisture condensing on the cool window glass.
This can be minimized if the climate control system
is used properly. There are two modes to clear fog or
frost from your windshield. Use the defog mode to
clear the windows of fog or moisture and warm
the passengers. Use the defrost mode to remove
fog or frost from the windshield more quickly.
For best results, clear all snow and ice from the
windshield before defrosting.
Select one of these available modes from the
right knob.
0(Defog):This mode directs most of the air to the
windshield and the floor outlets. A small amount of air is
also directed to the outboard outlets for the side
windows.
To help clear the side windows quickly, do the following:
1. Select the bi-level mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the temperature.
1(Defrost):This mode directs the air to the
windshield and the outboard outlets for the side
windows.
To help clear the windshield quickly, do the following:
1. Select the defrost mode.
2. Select the highest temperature.
3. Select the highest fan speed.
Do not drive the vehicle until all windows are clear.

Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature will only work when the
ignition is turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before using
this feature, clear as much snow from the rear
window as possible.
<(Rear Window Defogger):Press this button to
turn the rear window and outside mirror defogger on or
off. An indicator light in the button will come on to let
you know that the feature is activated.
If your vehicle has air conditioning, the rear window
defogger will turn off about 10 minutes after the button
is pressed. The defogger can also be turned off by
pressing the button again or by turning the engine off.
Notice:Do not use anything sharp on the inside
of the rear window. If you do, you could cut or
damage the warming grid, 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 knob located in the center of each outlet to
change the direction of the airflow.
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 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.

When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit,
do not, under any circumstances, stop and back up.
Drive on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested. If you
must start when you are not fresh — such as after
a day’s work — do not plan to make too many miles
that first part of the journey. Wear comfortable clothing
and shoes you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it needs
service, have it done before starting out. Of course,
you will find experienced and able service experts in
GM dealerships all across North America. They will be
ready and willing to help if you need it.Here are some things you can check before a trip:
•Windshield Washer Fluid:Is the reservoir full?
Are all windows clean inside and outside?
•Wiper Blades:Are they in good shape?
•Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
•Lamps:Are they all working? Are the lenses clean?
•Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all inflated to
the recommended pressure?
•Weather Forecasts:What is the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
•Maps:Do you have up-to-date maps?

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
4-26

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This uses less fuel for the heat that you get and it keeps
the battery charged. You will need a well-charged battery
to restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window
almost all the way to preserve the heat. Start the
engine again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can.
To help keep warm, you can get out of the vehicle
and do some fairly vigorous exercises every half hour
or so until help comes.
If Your Vehicle is Stuck in Sand,
Mud, Ice or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as
rocking can help you get out when you are stuck,
but you must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transaxle or other parts of
the vehicle can overheat. That could cause an
engine compartment re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transaxle back
and forth, you can destroy your transaxle. See
Rocking Your Vehicle to Get It Out on page 4-28.
