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 right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets. When you select this mode, the system
runs the air-conditioning compressor unless the outside
temperature is at or below freezing. The air-conditioning
indicator light will also be on in this setting. To defog
the windows faster, turn the temperature control
knob clockwise to the warmest setting.
0(Defrost):This mode directs most of the air to the
windshield, with some air directed to the side window
outlets and the oor outlets. When you select this mode,
the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The air-conditioning indicator light will also be on in
this setting.
To defog the side windows, set the right knob to oor
and the fan knob to the highest setting. You can use the
air conditioning while in this setting by pressing the air
conditioning button. In both cases, aim the side
outlets toward the side windows. For increased airow
to the side outlets, close the center outlets. Do not drive
the vehicle until all the windows are clear.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear):Press the button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible. An indicator light above
the button will come on to let you know that the
rear window defogger is activated.
The rear window defogger will turn off about 10 minutes
after the button is pressed. If turned on again, the
defogger will only run for about ve 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 anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t 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 louvers located on the air outlets to change the
direction of the airow.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the vehicle 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’re 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’s 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’re a big help.

road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-29.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is

service.
Anti-Lock Brake System
Warning Light
If your vehicle is equipped
with the anti-lock brake
system, the light will come
on when your engine is
started and may stay on for
several seconds. That’s
normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon
as possible and turn the ignition off. Then start the
engine again to reset the system. If the light still stays
on, or comes on again while you’re driving, your vehicle
needs service. If the regular brake system warning
light isn’t on, you still have brakes, but you don’t 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 on page 3-25.

System (ETS), this warning light should come on
briey as you start the engine. If the warning light
doesn’t come on, then have it xed so it will be ready to
warn you if there’s a problem.
If the warning light stays on, or comes on when you’re
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System warning light may come
on for the following reasons:
If you turn the system off by moving the shift lever
to FIRST (1) or SECOND (2), the warning light will
come on and stay on. To turn the system backon, move the shift lever back to a position other

stay on if your parking brake doesn’t release fully. If
the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the warning
light stays on after your parking brake is fully
released, it means there’s a problem with the
system.
If the traction control system is affected by an
engine-related problem, the system will turn off and
the warning light will come on.
If the vehicle is driven on an extremely rough road,
the warning light may come on momentarily but will
go off again when the vehicle leaves the rough
surface.
