Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
approximately 20 minutes after the button is pressed. If
turned on again, the defogger will run for the same
amount of time. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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 knob located
below or to the side of the
outlet, to change the
direction of the air ¯ow.

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 de¯ectors may
adversely affect the performance of the system.
·Keep the path under the front seats clear of objects
to help circulate the air inside your vehicle more
effectively.
·If the air¯ow seems low when the fan is at the
highest setting, the passenger compartment
air ®lter, if equipped, may need to replaced. For
more information, see
Passenger Compartment Air
Filter on page 3-26andPart A: Scheduled
Maintenance Services on page 6-4.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air ®lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle, underneath
the air inlet grille.
The ®lter traps most of the pollen from air entering the
Climate Control System. Like your engine's air
cleaner/®lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
®lter, see
Scheduled Maintenance on page 6-5.

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 brie¯y 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.
Your vehicle may also have a Driver Information Center
(DIC) that works along with the warning lights and
gages. See
Driver Information Center (DIC) on
page 3-49.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how
fast you're going, about how much fuel is in your tank and many other things you need to drive safely and
economically.

Tachometer
Your vehicle may have a
tachometer that displays
the engine speed in
thousands of revolutions
per minute (rpm).
Notice:Do not operate the engine with the
tachometer in the shaded warning area, or engine
damage may occur.
Safety Belt Reminder Light
When the key is turned to ON, a chime will come on for
about several seconds to remind people to fasten
their safety belts, unless the driver's safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will ¯ash for
several more.

Anti-Lock Brake System
Warning Light
If your vehicle is equipped
with anti-lock brakes, the
anti-lock brake system
warning light should come
on for a few seconds
when you turn the ignition
key to ON.
If the anti-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays 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, the anti-lock brake system needs
service and you don't have anti-lock brakes.
The anti-lock brake system warning light should come
on brie¯y when you turn the ignition key to ON. This
is normal. If the light doesn't come on then, have it ®xed
so it will be ready to warn you if there is a problem.
Traction Control System (TCS)
Warning Light
Your vehicle may have the
traction control system. If it
does, this warning light
may come on for the
following reasons:
·If you turn the system off by pressing the TRAC
OFF button located on the instrument panel, a
chime will sound and the warning light will come on
and stay on. To turn the system back on, press
the button again. The warning light should go off.
·If there's a brake system problem that is speci®cally
related to traction control, the traction control
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn off and the warning light will
come on until your brakes cool down.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.

Engine Coolant Temperature GageThis gage shows the engine coolant temperature.
It also provides an indicator of how hard your vehicle is
working. During the majority of the operation, the
gage will read 210ÉF (100ÉC) or less.
If you are pulling a load or going up hills, it is normal for
the temperature to ¯uctuate and approach the 250ÉF
(122ÉC) mark. When the gage reads greater than 250ÉF
(122ÉC), the HOT COOLANT TEMP light will be
illuminated in the message center and a chime will
sound continuously. If the gage reaches the 260ÉF
(125ÉC) mark, it indicates that the cooling system is
working beyond its capacity.

Engine Overheating on page 5-30.
