2-66 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 or kilometers. Press The ENG/MET
button which is located to the left of the speedometer to
change from mph to km/h.
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 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
A trip odometer can tell you how far you have driven
since you last set it to zero. To reset it, push the TRIP
RESET button. If your vehicle is equipped with a DIC,
see ªDICº in the Index for information on resetting the
trip odometer.
Tachometer (If Equipped)
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.

The following buttons are
on the DIC control panel
which is located to the left
of the steering column:
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
preferred trip number (1 or 2) is shown in the
DIC display, then press the RESET button.
The trip odometer will now accumulate miles until
the next reset.FUEL INFO: Press this button to display
fuel information.
Press the FUEL INFO button until the display shows
FUEL ECONOMY AVERAGE. Average fuel
economy is viewed as a long term approximation of
your overall driving conditions. To learn the average
fuel economy from a new starting point, press the
RESET button while the average fuel economy is
displayed in the DIC.
Press the FUEL INFO button until the display shows
FUEL ECONOMY INST. Instantaneous fuel
economy varies with your driving conditions, such
as acceleration, braking and the grade of the road
being traveled. The RESET button does not function
in this mode.
Press the FUEL INFO button until the display shows
FUEL RANGE. The fuel range will calculate the
remaining distance you can drive without refueling.
This calculation is based on the average fuel
economy for the last 25 miles (40.25 km) driven, and
the fuel remaining in the fuel tank. The RESET
button does not function in this mode.

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.

6-14 Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for good
performance and engine protection.
When to Change Engine Oil (Vehicles
Without the GM Oil Life System)
If any one of these is true for you, use the short trip/city
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop
-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every 3,000 miles (5 000 km) or 3 months
-- whichever
occurs first.If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months
-- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
When to Change Engine Oil (Vehicles With
the GM Oil Life System Option)
If so equipped, your vehicle has a computer that lets you
know when to change your engine oil. This is not based
on mileage, but on engine revolutions and engine
operating temperature. When the computer has calculated
that the oil needs changing, the GM Oil Life System
will indicate that a change is necessary. The mileage
between oil changes will vary depending on how you
drive your vehicle
-- usually between 3,000 miles
(5 000 km) and 7,500 miles (12 500 km) since your last
oil change. Under severe conditions, the system may come
on before 3,000 miles (5 000 km). Never drive your
vehicle more than 7,500 miles (12 500 km) or 12 months
(whichever occurs first) without an oil change.
The system won't detect dust in the oil. So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles (5 000 km) or sooner. Remember to reset
the Oil Life System whenever the oil is changed.
