Downloaded from www.Manualslib.com manuals search engine Average Speed
Press the
TRIP button until the average speed is
displayed, such as:
AVERAGE SPEED 62 MPH or
AVERAGE SPEED 100 km/h
Press reset in this mode to start calculating the average
speed. Press and hold RESET to clear.
Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as
OIL LIFE REMAIN 89%.
This is an estimate of the engine oil’s remaining useful
life. It will show 99% when the system is reset after an oil change.
It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will alert
you with the message CHANGE
OIL SOON.
When the oil life is down to zero, ‘you will receive the
message
CHANGE OIL NOW.
To reset the OIL LEE reminder after an oil change:
1. With the ignition on, press the TRIP button so the
OIL LIFE percentage is displayed.
2. Press RESET and hold for two seconds. The word
RESET
will appear, then OIL LIFE 99%.
Remember, you must reset the
OIL LIFE yourself after
each oil change. It will not reset itself. Also, be careful
not to reset the
OIL LIFE accidentally at any time other
than when the oil has just been changed. It can’t be reset
accurately until the next oil change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule in
this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil.
If you drive in dusty areas, change your oil
after every
3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do
so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine,
so be
sure to check your oil level often. See “Engine Oil” in
the Index.

Reduce your speed according to your speedometer, not
to your sense
of motion. After driving for any distance
at higher speeds, you may tend to think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip?
If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
GM
dealerships all across North America. They’ll be ready
and willing to help if you need it. Here are some things you can check before a
trip:

Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short’
time to avoid a major storm system?
Maps: Do you have up-to-date maps?

Downloaded from www.Manualslib.com manuals search engine Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant.
You can be burned
if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn
if the engine parts are hot
enough. Don’t spill coolant on a hot engine.

Downloaded from www.Manualslib.com manuals search engine vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or your
vehicle may fail a smog-check test. If
this occurs, return
to your authorized Corvette dealer for diagnosis to
determine the cause of failure. In the event it is
determined that the cause of the condition is the type of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not
his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If fuels containing MMT are used,
spark plug life may be reduced and your emission
control system performance may be affected. The
malfunction indicator lamp on your instrument panel
may turn on. If
this occurs, return to your authorized
Corvette dealer for service.
To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming
in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol,
and
reformulated gasolines may be available in your area to
help clean the air. General Motors recommends that you
use these gasolines if they comply with the
specifications described earlier.
NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask
an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.

Plan
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle.
To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties, See your
Warranty and Owner Assistance booklet, or your
GM
dealer for details.

Downloaded from www.Manualslib.com manuals search engine I Maintenance Schedule I
The services shown in this schedule up to 100,000 miles
(160
000 km) should be performed after 100,000 miles
(160
000 km) at the same intervals. The services shown
at
150,000 miles (240 000 km) should be performed at
the same interval after
150,000 miles (240 000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emissions warranty or limit recall liability prior to
the completion of the vehicle’s useful life. We, however,
urge that
all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
* Your Corvette has an Engine Oil Life Monitor. This
monitor will show you when to change the oil
-- usually
between
3,000 miles (5 000 km) and 10,000 miles
(16 000 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle more
than
10,000 miles (1 6 000 km) or 12 months without
an oil change. Use engine oil meeting the GM
Standard
GM47 18M.
The Engine Oil Life Monitor 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 if the
CHANGE
OIL light comes on. Remember to reset the
Oil Life Monitor when the oil has been changed. For
more information, see “Engine Oil Life Monitor” in
the Index.
