Speedometer and Tamper
Resistant 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 the new one can be set to the
mileage total of the old odometer, then that will be done.
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.
Dual Trip Odometers
In addition to the standard odometer, the cluster can also
display two separate trip odometers (designated by the
letter A or B in the display window) as well as your
vehicle's Engine Oil Life (designated by the word OIL
in the display window). The display can be toggled
between the odometer, the trip odometers and engine
oil life by quickly pressing and releasing the trip/reset
button located to the right of the temperature gage.
The display toggles once each time the trip/reset button
is pressed for less than 1.5 seconds. The display toggles
in the following sequence: Odometer
- Trip
Odometer A
- Trip Odometer B - Engine Oil Life.
If the engine oil life is left on the display, it will
automatically toggle back to the odometer after
approximately 15 seconds. Each of the two trip
odometers can be used to keep track of different trip
distances (for example, the mileage of a long trip
and the mileage driven on the current tank of fuel).
The trip odometers will continue to keep track of miles
(kilometers) driven even if they are not currently
displayed. To reset the odometer to zero (0), press and
hold the trip/reset button for at least 1.5 seconds, but less
than three seconds. Only the trip odometer that is
showing in the display will be reset.

2-102
Retro-Active Reset
Each of the two trip odometers has a feature called
retro
-active reset. This feature can be used to set either
(or both) trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip
odometer at the beginning of a trip. To use the
retro
-active reset feature, press and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. (If you use the retro
-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
(kilometers) you drove during the last ignition cycle.)
Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have driven
5.0 miles (8.0 km) since you started your vehicle, and
then activate the retro
-active reset feature, the display
will show 5.0 miles (8.0 km). As you drive, the display
will then increase to 5.1 miles (8.2 km), 5.2 miles
(8.4 km), etc. Only the trip odometer that is displayed
will be affected by the retro
-active reset so that both trip
odometers can be used separately.
Warning Lights, Gages, Messages
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.

Service
Your dealer knows your vehicle best and wants you to
be happy with it. We hope you'll go to your dealer for
all your service needs. You'll get genuine GM parts and
GM
-trained and supported service people.
We hope you'll want to keep your GM vehicle all GM.
Genuine GM parts have one of these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you'll
want to use the proper service manual. It tells you much
more about how to service your vehicle than this manual
can. To order the proper service manual, see ªService
and Owner Publicationsº in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work, see ªServicing Your Air
Bag
-Equipped Vehicleº in the Index.
You should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See ªMaintenance Recordº in the Index.

6-16 When to Change Engine Oil
(GM Oil Life System
)
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A change engine oil message will come on.
Change your oil as soon as possible within the next
two times you stop for fuel. It is possible that, if you
are driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for
over a year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset. It is also important to check your oil
regularly and keep it at the proper level.
If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed.How to Reset the Change Engine Oil Message
The GM Oil Life System
calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to a change
engine oil message being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL is
displayed on the Driver Information Center.
2. When OIL is displayed, push and hold the
trip/reset button for five seconds. The number will
disappear and be replaced by 100 (indicating 100%
oil life remaining).
3. Turn the key to OFF.
If the change engine oil message comes back on,
the engine oil life monitor has not reset. Repeat
the procedure.
