Active Handling System
The 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 ACT HNDLG WARMING UP message may be
displayed in the DIC after exceeding 12 mph (20 km/h)
for 30 seconds. The Active Handling System is off until
the WARM UP COMPLETE message is displayed.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.
The SERVICE ACTIVE
HNDLG message will be
displayed, the instrument
cluster light will come on,
and a chime will sound to
let you know if there is a
problem with the system.
See ªDriver Information
Center Messagesº in the
Index for more information.
When this light and the SERVICE ACTIVE HNDLG
message are on, the system is not operational.
Adjust your driving accordingly.

4-12
The Active Handling System comes on automatically
whenever you start your vehicle. To help maintain
directional control of the vehicle, you should always
leave the system on. You can turn the system off if you
ever need to. If you turn the Active Handling System
off, the Traction Control System will also be turned off.
Adjust your driving accordingly.
To turn the system off, press
the ACTIVE HANDLING
button on the console. You
can turn the system on and
off at any time by pressing
the button. The DIC will
display the appropriate
message when you push
the button.
Competitive Driving Mode
The driver can select the optional handling mode by
pressing the ACTIVE HANDLING button on the
console for more than five seconds. Competitive
Driving mode allows the driver to have full control of
the rear wheels while the Active Handling System
helps steer the vehicle by selective brake application.
The instrument cluster light will not be on. The Traction
Control System will not be operating. Adjust your
driving accordingly.
When you press the ACTIVE HANDLING button
again, or turn the ignition to ACC, the Active
Handling and Traction Control Systems will be on.
The TRAC/ACT HNDLG
-ON message will be
displayed temporarily in the DIC and a chime will
be heard.

Engine Overheating
You will find an engine coolant temperature gage on the
instrument panel cluster and a COOLANT OVER
TEMP message on the Driver Information Center (DIC).
See ªEngine Coolant Temperature Gageº and ªCoolant
Over Temp DIC Messageº in the Index.
Overheated Engine Protection
Operating Mode
If an overheated engine condition exists 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).
NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life system. See ªEngine Oilº in the Index.

6-16
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.
How to Reset the Change Oil Soon Message
The GM Oil Life System
calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system so it can calculate
when the next oil change is required. If a situation
occurs where you change your oil prior to a CHANGE
OIL SOON message being turned on, reset the system.To reset the CHANGE OIL SOON message after an oil
change, do the following:
1. Turn the ignition to ON, with the engine off.
2. Press the TRIP button so the OIL LIFE percentage
is displayed.
3. Press RESET and hold for two seconds. OIL LIFE
REMAIN 100% will appear.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long.
Clean your skin and nails with soap and water, or a
good hand cleaner. Wash or throw away clothing or
rags containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it in
the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by taking it
to a place that collects used oil. If you have a problem
properly disposing of your used oil, ask your dealer,
a service station or a local recycling center for help.

How to Check
Use a good quality pocket
-type gage to check tire
pressure. You can't tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they're underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and moisture.
If your vehicle is equipped with the Tire Pressure
Monitor, you can check tire inflation pressures while
driving. After you've reached a speed of 15 mph
(24 kmh) 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.
For more information, see ªTire Pressure Monitorº and
ªDriver Information Center (DIC)º in the Index.

6-45
Changes or modifications to this system by other than
an authorized service facility could void authorization to
use this equipment.
If a tire's inflation pressure is between 5 psi (35 kPa)
and 25 psi (170 kPa), you will see a message on the
Driver Information Center. This message will show
which tire is underinflated and two chimes will sound.
An example would be LOW TIRE PRESSURE
-LR.
This would mean that the inflation pressure in your left
rear tire is between 5 psi (35 kPa) and 25 psi (170 kPa).
If the inflation pressure in the tire drops below 5 psi
(35 kPa), the message would read FLAT TIRE
-LR
and four chimes will sound. See ªDriver Information
Centerº in the Index.
The TPM will also alert you if a tire's pressure is higher
than 42 psi (290 kPa). The message will show which tire
is overinflated and two chimes will sound. An example
would be HIGH PRESSURE
-LR. This would mean
that the inflation pressure in your left rear tire is higher
than 42 psi (290 kPa). See ªDriver Information Centerº
in the Index.If a tire pressure message appears on the Driver
Information Center, stop as soon as you can. Have the
tire pressures checked and set to those shown on your
Tire Loading Information label. See ªInflation
-- Tire
Pressureº in the Index.
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.

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.
