2-79 Speedometer and Odometer
Your speedometer lets you see your speed in either
miles per hour (mph) or kilometers per hour (km/h).
There is only one scale for mph and km/h. When you
press the E/M (English/metric) button on the Driver
Information Center (DIC), the cluster will calculate the
proper speed and move the needle to the correct position.
Either the MPH or the km/h telltale will illuminate,
depending on which measurement you choose.
To read the odometer with the ignition off, turn on the
parking lamps.
You may wonder what happens if your vehicle needs a
new odometer installed. The mileage total of the new
odometer will be set to the original miles (kilometers) of
the old odometer. See your dealer if a new odometer
must be replaced in your vehicle.
Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
Fuel will shut off at about 6200 rpm (6500 rpm for Z06).
If you continue to drive your vehicle at the fuel shut off
rpm, you could damage your engine. Be sure to operate
your vehicle below the fuel shut off rpm or reduce your
rpm quickly when the fuel shuts off.

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
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
15,000 miles (25 000 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 15,000 miles (25 000 km)
or 12 months (whichever occurs first) without an
oil change. Use engine oil meeting the GM
Standard GM4718M.
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 if the CHANGE
OIL SOON message appears. Remember to reset the
Engine Oil Life Monitor whenever the oil is changed.
How to Reset the Change Oil Soon Message
To reset the CHANGE OIL SOON message after an oil
change, do the following:
1. Turn the ignition to ON, with the engine off.
2. Press the TRIP button so the OIL LIFE percentage
is displayed.
3. Press RESET and hold for two seconds. OIL LIFE
REMAIN 100% will appear.
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 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.
