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.
Care of Your Compact Discs
Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust. If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Care of Your Compact Disc Player
The use of CD lens cleaner discs is not advised, due to
the risk of contaminating the lens of the CD optics with
lubricants internal to the CD mechanism.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged. If the mast should ever become
slightly bent, you can straighten it out by hand. If the
mast is badly bent, as it might be by vandals, you should
replace it.
Check every once in a while to be sure the mast is still
tightened to the rear quarter panel.
Power Antenna Mast Care (If Equipped)
Your power antenna will look its best and work well
if it's cleaned from time to time. To clean the
antenna mast:
1. Turn on the ignition and radio to raise the antenna.
2. Dampen a clean cloth with mineral spirits or
equivalent solvent.
3. Wipe the cloth over the mast sections, removing
any dirt.
4. Wipe dry with a clean cloth.
5. Make the antenna go up and down by turning the
radio or ignition off and on.
6. Repeat if necessary.

Towing Your Vehicle
CAUTION:
To help avoid serious personal injury to you
or others:

Never let passengers ride in a vehicle that is
being towed.

Never tow faster than safe or posted speeds.

Never tow with damaged parts not
fully secured.

Never get under your vehicle after it has
been lifted by the tow truck.

Always secure the vehicle on each side with
separate safety chains when towing it.

Use only the correct hooks.
NOTICE:
Use the proper towing equipment to avoid
damage to the bumper, fascia or fog lamp areas
of the vehicle.
With current trends in automotive styles and design, it is
essential that the correct towing equipment is used to
tow a vehicle. Your vehicle can be towed with wheel
-lift
or car
-carrier equipment.
Consult your dealer or a professional towing service if
you need to have your vehicle towed. See ªRoadside
Assistanceº in the Index.
Engine Overheating
You will find an engine coolant temperature gage on the
instrument cluster and a COOLANT OVER TEMP
message on the Driver Information Center (DIC).
Overheated Engine Protection
Operating Mode
Should an overheated engine condition exist and the
messages COOLANT OVER TEMP and REDUCED
ENGINE POWER are displayed, along with the Check
Engine light, an overheat protection mode which
alternates firing groups of cylinders helps prevent
engine damage. In this mode, you will notice a loss in
power and engine performance. This operating mode
allows your vehicle to be driven to a safe place in an
emergency; you may drive up to 50 miles (80 km).

Your Corvette 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 ªStarburstº symbol at
all temperatures. If temperatures are above 0F (
-18C),
you may substitute SAE 10W
-30 with the ªStarburstº
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 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 Oil Life Monitor 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
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 GM4718M.
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 km) or sooner if the CHANGE OIL
SOON message comes on. Remember to reset the
Engine Oil Life Monitor whenever the oil is changed.
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 ªService and Owner
Publicationsº in the Index.
How to Reset the Engine Oil Life Monitor
To reset the monitor 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%.

CAUTION:
When the LOW TIRE PRESSURE or FLAT
TIRE message is displayed on the Driver
Information Center, your vehicle's handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of your vehicle. You or others could be
injured. Don't drive over 55 mph (90 km/h) when
the LOW TIRE PRESSURE or FLAT TIRE
message is displayed. Drive cautiously, and check
your tire pressures as soon as you can.
If a tire goes flat, you won't need to stop on the side of
the road to change the tire. You can just keep on driving.
The shorter the distance you drive and the slower the
speed, the greater the chance that the tire will not have
to be replaced. If you drive on a deflated EMT for
50 miles (80 km) or less and at speeds of 55 mph
(90 km/h) or less, there is a good chance that the tire can
be repaired. The tire can operate effectively with no air
pressure for up to 200 miles (320 km) at speeds up to
55 mph (90 km/h), but the tire would then have to be
replaced. When a tire is filled with air, it provides acushion between the road and the wheel. Because you
won't have this cushion when driving on a deflated tire,
try to avoid potholes that could damage your wheel and
require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you've driven on
the tire in a deflated condition. When a tire has been
damaged, or if you've driven any distance on a deflated
EMT, check with an authorized Goodyear EMT Service
Center to determine whether the tire can be repaired or
should be replaced. To maintain your vehicle's extended
mobility feature, all replacement tires must be Extended
Mobility Tires. As soon as possible, contact the nearest
authorized Chevrolet or Goodyear EMT servicing
facility for inspection and repair or replacement. Call
Chevrolet at 1
-800-CHEV-USA (1-800-243-8872)
or Goodyear at 1
-800-789-9878 24-hours a day for
information on the location of the nearest EMT
servicing facility. In Canada, contact the Customer
Communication Center at 1
-800-263-3777, or Canadian
Roadside Assistance at 1
-800-268-6800. You can also
use the Goodyear number listed above to locate an
authorized EMT servicing facility.

6-45 Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
rear edge of the driver's door, shows the correct
inflation pressures for your tires when they're cold.
ªColdº means your vehicle has been sitting for at least
three hours or driven no more than 1 mile (1.6 km).
NOTICE:
Don't let anyone tell you that underinflation or
overinflation is all right. It's not. If your tires
don't have enough air (underinflation), you can
get the following:

Too much flexing

Too much heat

Tire overloading

Bad wear

Bad handling

Bad fuel economy.
NOTICE: (Continued)
NOTICE: (Continued)
If your tires have too much air (overinflation),
you can get the following:

Unusual wear

Bad handling

Rough ride

Needless damage from road hazards.
When to Check
Check your tires once a month or more.
How to Check
With the Tire Pressure Monitor, you can check tire
inflation pressures while driving. After you've reached a
speed of 15 mph (24 km/h) or more, press and release
the GAGES button on the Driver Information Center
(DIC) until the front tire pressures are displayed. Then,
press and release the GAGES button for the rear tire
pressures. If the display doesn't show tire pressure, or if
the SERVICE TIRE MON SYS message appears, see
your dealer for service.

CAUTION:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack, you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
CAUTION:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure to place the jack in the
proper location before raising the vehicle.
If you ever use a jack to lift your Corvette, such as to
display it at a show, follow the instructions that came
with the jack, and be sure to use the correct lifting points
to avoid damaging your vehicle.
NOTICE:
Lifting your vehicle improperly can damage your
vehicle and result in costly repairs not covered by
your warranty. To lift your vehicle properly,
follow the advice in this part.
To help prevent vehicle damage:

Be sure to place a block or pad between the
jack and the vehicle.

Make sure the jack you're using spans at
least two crossmember ribs.

Lift only in the areas shown in the
following pictures.
For additional information, see your dealer and
the Chevrolet Corvette service manual.
