2-70 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).
Your vehicle has a tamper
-resistant odometer. You may
wonder what happens if your vehicle needs a new
odometer installed. If possible, the new one has to be set
to the same reading the old one had. If it can't be, then
it's set at zero and a label must be put on the driver's
door to show the old mileage reading and when the new
odometer was installed.
Trip Odometer
A trip odometer can tell how far you've driven since
you last set it back to zero. To reset it, push the RESET
button. The trip odometer is reset through the DIC if
your vehicle is equipped with this feature.
Tachometer
The tachometer tells you
how fast the engine is
running. It displays engine
speed in thousands of
revolutions per
minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

DIC Controls and Displays
There are two lines in the DIC display. The bottom line
on the display area is left blank when the DIC displays
the driver number identified when entering the vehicle.
You can have your dealer program your name to
appear on this display line. See your dealer for
more information.When you turn the ignition on, the DIC will display
your DRIVER NUMBER. The system will then perform
a status check and display any messages if a problem
is detected.
If there are no problems detected, the display will return
to the mode selected by that driver the last time the
ignition was turned off.
If a problem is detected, a diagnostic message will
appear in the display. The following pages will show the
messages you may see on the DIC display.
The message center is continuously updated with the
vehicle's performance status.
ODO/TRIP
When this button is pressed, the display will show the
total mileage, and TRIP 1 or TRIP 2 miles. TRIP 1 and
TRIP 2 will display the miles traveled since the last
reset. To reset the trip odometer, press the ODO/TRIP
button until the trip miles are shown in the DIC display,
then press the RESET button. The trip odometer will
now accumulate miles until the next reset.

6-54 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.
