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 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.

Driver Information Center (DIC)
(If Equipped)
Your vehicle may be equipped with a Driver
Information Center (DIC). The DIC will display
information about how your vehicle is functioning,
as well as warning messages if a system problem is
detected. This feature also allows two different drivers
to store and recall their own personal choice settings.
See ªDIC Personal Choice Programmingº later in
this section.
DIC Displays and Controls
There are two lines in the DIC display. 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.
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.

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.

6-15 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 and filter changes will vary
depending on how you drive your vehicle
-- usually
between 3,000 miles (5 000 km) and 10,000 miles
(16 000 km) since your last oil and filter change.
Under severe conditions, the system may come on
before 3,000 miles (5 000 km). Never drive your vehicle
more than 10,000 miles (16 000 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 and filter
every 3,000 miles (5 000 km) or sooner. Remember
to reset the Oil Life System whenever the oil is changed.How to Reset the Oil Life System (If Equipped)
After changing the engine oil, the Oil Life System
should be reset. It will not reset itself. To reset the Oil
Life System, press and hold the RESET button on the
DIC for more than five seconds while OIL LIFE INDEX
is being displayed. The oil life will change to 100%.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
See the manufacturer's warnings about the use and
disposal of oil products.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing
oil from the filter before disposal. Don't ever dispose of
oil by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.
