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).
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Press the reset button to toggle between the trip
odometer and the regular odometer. Holding the reset
button for two seconds while the trip odometer is
displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.
Engine Hour Meter Display
The odometer can also display the number of hours the
engine has run. To display the hour meter, turn the
ignition off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for up
to 30 seconds, or until the ignition is turned on.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
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.
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.

2-84 Fuel
Each press of the FUEL button will change the
display between the fuel remaining range, average
fuel economy, instantaneous fuel economy and a
blank display.
The average fuel economy can be reset using the
RESET button.
Trip
Each press of the TRIP button will change the
display between personal trip computer, business trip
computer, timer, vehicle history, annual mileage and a
blank display.
Personal Trip Computer and Business
Trip Computer
Each press of the arrow button will change the
display between turn on/off, trip odometer, fuel used,
average fuel economy and average speed.
The ON/OFF button will turn the trip computer on
and off. The information on the trip computer only
gets updated when it is turned on. The personal and
business computers are independent, i.e. turning one
of them on does not turn the other off.All information associated with the trip computer
will be reset when the RESET button is pressed.
If the RESET button is pressed and held for more
than two seconds, all of the trip computer settings
will reset starting from the last ignition cycle
(turning the ignition from OFF to RUN). This
feature is for someone who has forgotten to reset the
trip computer when pulling out of the driveway and
does not realize it until after driving for awhile.
Timer
Each press of the ON/OFF button will turn the timer
on or off.
The RESET button will reset the timer to 00:00:00.
If turned on, the timer will accumulate whenever
the SIC is powered (the engine does not have to
be running).
The timer will rollover after 99:59:59.

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
clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.Used Replacement Wheels
CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used or
how far it's been driven. It could fail suddenly
and cause an accident. If you have to replace a
wheel, use a new GM original equipment wheel.
