The mirror can be calibrated in one of two ways:
Drive the vehicle in circles at 5 mph (8 km/h) or
less until the display reads a direction, or
drive the vehicle on your everyday routine.
Mirrors equipped with OnStar controls can be placed in
calibration mode by pressing and holding the on off
button until a ªCº is shown in the compass display.
Compass Variance
The mirror is set in zone eight upon leaving the factory.
It will be necessary to adjust the compass to compensate
for compass variance if you live outside zone eight.
Under certain circumstances, as during a long distance
cross
-country trip, it will be necessary to adjust for
compass variance. Compass variance is the difference
between earth's magnetic north and true geographic
north. If not adjusted to account for compass variance,
your compass could give false readings.
To adjust for compass variance:
1. Find your current location and variance zone number
on the following zone map.
2. Press and hold COMPASS (or the on/off button for
mirrors equipped with OnStar controls) until a zone
number appears in the display.
3. Once the zone number appears in the display, press
the COMPASS (or the on/off button for mirrors
equipped with OnStar controls) button quickly until
the correct zone number appears in the display.
Stop pressing the button and the mirror will
return to normal operation. If ªCº appears in the
compass window, the compass may need calibration.
See ªCompass Calibrationº explained previously.

2-65 Speedometer and Odometer
Your speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). Your
odometer shows how far your vehicle has been driven,
in either miles (used in the United States) or kilometers
(used in Canada).
The speedometer shows a top speed of 140 mph
(220 km/h). This is not intended to be the vehicle's
top speed.
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
Your trip odometer tells you how far you have driven
since you last reset it. Your vehicle is equipped with two
trip odometers, ªAº and ªBº.
Press the TRIP A/B button to change which trip odometer
is displayed.
Press the TRIP RESET button to reset the trip odometer
that is currently being displayed.

2-66 Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
If your engine speed equals or exceeds the safe limit for
operation, the message HOT...REDUCE ENG RPM is
displayed on the Driver Information Center (DIC).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or when the message HOT...REDUCE
ENG RPM is displayed. Engine damage may occur.
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 briefly 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.

2-68 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, 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, see ªAir Bagº in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
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 inflate in a crash, or they
could even inflate 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 flash for a few seconds
when you turn the ignition key to RUN. If the light
doesn't come on then, have it fixed so it will be ready
to warn you if there is a problem.
On the DIC an AIR BAG PROBLEM message will
be displayed when there is a problem with the air bag
system. See ªDIC Warnings and Messagesº in the
Index for more information.

2-69 Battery Warning Light
This light will come on
briefly when you start the
vehicle, as a check to show
you it is working; then it
should go out.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a generator problem or
another electrical system problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and climate control system.
On the DIC a CHECK CHARGE SYSTEM message
will be displayed and a warning chime will sound.
See ªDIC Warnings and Messagesº in the Index
for more information.
Brake System Warning Light
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't 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 is a brake problem.
Have your brake system inspected right away.
United States Canada
This light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then, have it
fixed so it will be ready to warn you if there's a 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 floor.
It may take longer to stop. If the light is still on, have the
vehicle towed for service. See ªTowing Your Vehicleº
in the Index.

CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake doesn't release
fully. If you try to drive off with the parking brake set,
a chime will also come on until you release the parking
brake. If the light stays on after your parking brake is
fully released, it means you have a brake problem.
A PARK BRAKE SET message will be displayed on
the Driver Information Center (DIC) while the park
brake is set and the vehicle is moving. The message
will not come on if the transaxle is in PARK (P).
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, the light(s) will
come on when you start
your engine 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 ªBrake System
Warning Lightº earlier in this section.
The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

2-77 Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
This light will come on for a few seconds when you turn
the ignition key to RUN to let you know it is working.
Fuel Gage
United States CanadaWhen the ignition is on, your fuel gage tells you about
how much fuel you have left.
When you have less than 3.0 gallons (11.3 L) of
fuel remaining, the DIC message LOW FUEL will
be displayed and a chime will sound. You need to get
more fuel right away.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank's capacity to
fill the tank.
The gage moves a little when you turn a corner
or speed up.
The tank is not necessarily empty when the gage
reads empty. There is a reserve of about 1.5 gallons
(5.6 L) in the tank. You should still get more fuel
as soon as possible.
