That’s’normal.
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake warning light on can lead to an accident.
If
the light is still on after you’ve pulled off the road
and stopped carefully, have the vehicle towed
for service.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon as
possible and turn the ignition
off. Then start the engine
again to reset the system.
If the light still stays on, or
comes
on again while you’re driving, your vehicle needs
service. If the regular brake system warning light isn’t
on, you still have brakes, but you don’t have anti-lock
brakes. If the regular brake system warning light
is also
on, you don’t have anti-lock brakes and there’s a
problem with your regular brakes. See “Brake System
Warning Light” earlier in this section.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
ON. If the
light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.

Downloaded from www.Manualslib.com manuals search engine Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLN to indicate
that you have used your tape player for
50 hours without
resetting the tape clean timer. If this message appears on
the display, your cassette tape player needs to be
cleaned. It will still play tapes, but you should clean it as
soon as possible to prevent damage to your tapes and
player.
If you notice a reduction in sound quality, try a
known good cassette to see
if it is the tape or the tape
player at fault.
If this other cassette has no improvement
in sound quality, clean the tape player. Cleaning may be done with a scrubbing action,
non-abrasive cleaning cassette with pads which scrub
the tape head as the hubs
of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning. Insert
the cassette at least three times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your dealership.
You may also choose a non-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head.
This type of cleaning cassette will not
eject and, it may not clean as thoroughly as the
scrubbing type cleaner.
After you clean the player, press and hold
EJECT for
five seconds to reset the CLN indicator. The radio will
display --- to show the indicator was reset.
Cassettes are subject to wear and the sound quality
may degrade over time. Always make sure the cassette tape
is in good condition before you have your tape
player serviced.

Downloaded from www.Manualslib.com manuals search engine 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 Corvette engine is filled at the factory with a
Mobil
l@ 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
0 OF (- 18 O C),
you may substitute
SAE low-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. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
Your Corvette has an Engine Oil Life Monitor. This
feature will let you know when to change your oil and
filter
-- 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 (16
000 km) or 12 months
(whichever occurs first) without an oil change. Use
engine oil meeting the GM Standard GM47 18M.
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 lun) or sooner if the CHANGE OIL
light comes on. Remember to reset the Engine Oil Life
Monitor when the oil has been changed. For more
.information, see “Engine Oil Life Monitor” in the Index.
When Changing the Engine Oil
There is a special procedure for changing engine oil,
contact your dealer for additional information or the
procedure can be found in a Corvette Service Manual.
To purchase a service manual, see “Service and Owner
Publications” in the Index.
How to Reset the Engine Oil Life Monitor
Press RESET to acknowledge the CHANGE OIL SOON
warning. The oil page will then show a message such as
OIL LIFE
0%. To reset the monitor, press and hold
RESET for two seconds. You will then receive a
message such as OIL LIFE
99%.
