HIGH TRANS TEMP (Automatic Transmission
Only): You will hear four chimes when this message
is displayed. To acknowledge this warning, press the
RESET button. After you press the RESET button,
the message will be displayed every 10 minutes until the
condition changes. If you do not press RESET,
the message remains on the display until the
condition changes.
If the transmission fluid temperature rises above
270
F (132
C) or rises rapidly, this message is
displayed. The transmission may shift gears or apply the
torque converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can cause
the transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.If the HIGH TRANS TEMP message is displayed
during normal vehicle operation on flat roads,
your vehicle may need service. See your dealer for
an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message is
displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
an optional computer controlled system to assist the
driver in controlling the vehicle in difficult driving
conditions. You may feel or hear the system working
and see the ACTIVE HANDLING message displayed in

RESET, a message will reappear and you will hear a
chime every 10 minutes until this condition changes.
This message indicates that the pressure in one of your
tires is higher than 42 psi (290 kPa). Next to the HIGH
TIRE PRESSURE message, you can see either LF
(left front), LR (left rear), RF (right front) or RR (right
rear) to indicate to you which tire is higher than 42 psi
(290 kPa). You can receive more than one tire pressure
message at a time. To read other messages that may
have been sent at the same time, press RESET. If a tire
pressure message appears on the DIC, stop as soon as
you can. Have the tire pressures checked and set to those
shown on your Tire Loading Information Label.
See ªExtended Mobility Tiresº and ªTire Inflationº
in the Index.SERVICE TIRE MON SYS: If this message comes on,
a part on the Tire Pressure Monitor (TPM) is not
working properly. If you drive your vehicle while any of
the four sensors are missing or inoperable, the warning
will come on in approximately 10 minutes. If all four
sensors are missing, the warning will come on in
approximately 15 to 20 minutes. (All the sensors would
be missing, for example, if you put different wheels on
your vehicle without transferring the sensors.) If the
warning comes on and stays on, there may be a problem
with the TPM. See your dealer.

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.
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.

When this light and the SERVICE TRACTION
SYSTEM message are on, the system will not limit
wheel spin. Adjust your driving accordingly.
The TCS system automatically comes on whenever you
start your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the TCS system off if you
ever need to.
To turn the system off, press
the button located on the
console. You can turn the
system ON or OFF at any
time by pressing the TCS
switch. The DIC will
display the appropriate
message when you push
the button.
Active Handling System (Option)
The optional Active Handling System is a computer
controlled system that helps the driver maintain
directional control of the vehicle in difficult driving
conditions. This is accomplished by selectively applying
any one of the vehicle's brakes.
When you first start your vehicle and begin to drive
away (6 mph (10 km/h)), the message ACT HNDLG
WARMING UP may be displayed in the DIC, the
instrument cluster light will be on, and a chime will
sound. This is normal. You can acknowledge this
message by pressing the RESET button. The Active
Handling System performance is affected until the
message, WARM UP COMPLETE, is displayed in
the DIC.
The ACTIVE HANDLING message will come on when
the system is operating. See ªDriver Information Center
Messagesº in the Index for more information. You may
also feel or hear the system working. This is normal.

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%.
