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.
/(Floor/Defog):This mode directs half of the air to
the windshield and the side window outlets and the other
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.
Recirculation is not available in this mode.
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.
Recirculation is not available in this mode.
1(Maximum Defrost):This mode directs most of
the air to the windshield, with some air directed to
the side window outlets and the oor outlets. The rear
window defogger and heated outside mirrors will turn on,
and the fan speed will be at the highest setting (5).
The temperature will be at the hottest setting also.
Recirculation is not available in this mode.
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 on.
=(Rear):Press this button on the right knob to turn
the rear window defogger on or off. An indicator light
on the button will come on to let you know that the rear
window defogger is activated.
When the rear defogger button is pressed, the outside
heated mirrors will warm to help clear any fog or
frost from the surface of the mirrors.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Outlet Adjustment
Use the levers located in
the center of each 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 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 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 also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-44for
more information.

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 you’ve used, and many other things you’ll need to know to drive safely
and economically.

Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Turn the ignition to RUN and press the
trip information button located on the steering wheel.
SeeDIC Controls and Displays on page 3-44for more
information.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it can’t, then it’s set at zero, and a label must
be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle
has been driven since you last set the trip odometer
to zero.
Your trip odometer is part of your Driver Information
Center (DIC). The trip information button toggles
to display your trip odometer, Trip A, and Trip B
functions. See “Trip Odometer” underDIC Controls and
Displays on page 3-44for more information.
Tachometer
Notice:If you operate the engine with the
tachometer in the shaded warning area, your vehicle
could be damaged, and the damages would not
be covered by your warranty. Do not operate
the engine with the tachometer in the shaded
warning area.
The tachometer displays the engine speed in revolutions
per minute (rpm).
Fuel will shut off at about 6500 rpm. It will turn back on
again once the vehicle rpm drops below 6500.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for 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.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel cluster, which shows the air bag symbol.
The system 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 system, seeAir Bag Systems on
page 1-42.
This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then
the light should go out.
This means the system is
ready.

Page 143 of 398
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in ate in a crash, or they
could even in ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.The air bag readiness light should ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.

Air Bag Off Light
When you turn the passenger’s frontal air bag off, the
air bag off light, located on the roof panel above
the rearview mirror, will come on and stay on to remind
you that the air bag has been turned off. This light
will go off when you turn the passenger’s frontal air bag
back on again. SeeAir Bag Off Switch on page 1-51
for more on this, including important safety information.{CAUTION:
If the passenger’s frontal air bag is turned off
for a person who is not in a risk group
identi ed by the national government, that
person will not have the extra protection of a
frontal air bag. In a crash, the air bag would
not be able to in ate and help protect the
person sitting there. Do not turn off the
passenger’s frontal air bag unless the person
sitting there is in a risk group. SeeAir Bag Off
Switch on page 1-51for more on this,
including important safety information.
