mileage CHEVROLET CORVETTE 2002 5.G Owners Manual

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.

SAE 5W-30
As shown in the viscosity chart, SAE 5W
-30 is
best for your vehicle. However, you can use SAE
10W
-30 if it's going to be 0F (-18C) or above.
These numbers on an oil container show its viscosity,
or thickness. Do not use other viscosity oils such as
SAE 20W
-50.
Oils meeting these
requirements should
also have the starburst
symbol on the container.
This symbol indicates
that the oil has been
certified by the American
Petroleum Institute (API).
You should look for this on the oil container, and use
only those oils that are identified as meeting GM
Standard 4718M and have the starburst symbol on the
front of the oil container.
Your vehicle's engine is filled at the factory with a
Mobil 1
 synthetic oil, which meets all requirements
for your vehicle.Substitute Engine Oil: When adding oil to maintain
engine oil level, oil meeting GM Standard GM4718M
may not be available. You can add substitute oil
designated SAE 5W
-30 with the starburst symbol at
all temperatures. If temperatures are above 0F (
-18C),
you may substitute SAE 10W
-30 with the starburst
symbol. Substitute oil not meeting GM Standard
GM4718M should not be used for an oil change.
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
(GM Oil Life System)
Your vehicle has a computer that lets you know when
to change your 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.

Scheduled Maintenance
7-6Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the
Engine Oil Life System
(or every 12 months,
whichever occurs first). Reset the 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 OIL SOON 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. See ªOil Life Systemº in the Index
for information on resetting the system.
Use engine oil meeting the GM Standard GM4718M.
