vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your
dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow
the proper installation instructions included with

Mode Buttons
@
(Recirculation):If your vehicle has air
conditioning, you will have the recirculation feature. This
mode recirculates air inside the cabin, and prevents
outside air from coming in the vehicle. It can be used to
prevent outside odors from entering your vehicle and
cool the air inside your vehicle more quickly. Press this
button to turn the recirculation mode on or off. An
indicator light on the button will come on to let you know
the recirculation mode is activated.
Recirculation is only available in the bi-level and vent
modes. If you push the recirculation button while
the system is in any other mode, the light on the button
will ash to indicate that recirculation is not available.
#(Air Conditioning):Your vehicle may have air
conditioning. Press this button to turn the air-conditioning
system on or off. An indicator light on the button will
come on to let you know the air conditioning is activated.
When the system is on, this setting cools and
dehumidies the air entering your vehicle.
The air conditioning will not function if the fan is
turned off.You may notice a slight change in engine performance
when the air conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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
(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 and side windows. 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.
Turn the mode knob on the climate control panel
clockwise to select the defog or defrost modes.

Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors 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.
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly — and even
dangerous. So please get to know your warning lights
and gages. They are a big help.
Your vehicle may also have a DIC that works along with
the warning lights and gages. SeeDriver Information
Center (DIC) on page 3-30for more information.

with the tachometer in the shaded warning area.
Safety Belt Reminder Light

checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
systems, seeAir Bag Systems on page 1-62.

vehicle serviced right away if the air bag
readiness light stays on after you start
your vehicle.

bag could inate even though the switch is off.
If this ever happens, do not let anyone whom
the national government has identied as a
member of a passenger air bag risk group sit

Transmission)
This light appears when
you need to shift to the
next higher gear on
a manual transmission
vehicle.

more information.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.This light should come on briey when you turn the
ignition key to ON. If it does not come on then, have
it xed so it will be ready to warn you if there is
a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake.
SeeParking Brake on page 2-31for more information.
The light will stay on if your parking brake does not
release fully. If it stays on after your parking brake is
fully released, it means you have a brake problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push, or the pedal may go closer to the
