2005 CHEVROLET CORVETTE warning

SERVICE TIRE MONITOR: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 about 60 minutes. A sensor
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 GM dealer.

indicates that the pressure in one of your tires is
lower than 10 psi (68 kPa). Next to the TIRE FLAT
message, you can see either LEFT FRONT, RIGHT
FRONT, LEFT REAR or RIGHT REAR to indicate to you
which tire is at. 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
the RESET button. 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. SeeExtended Mobility
Tires on page 5-56andInation - Tire Pressure on
page 5-58.
{CAUTION:
When the LOW TIRE PRESSURE or TIRE FLAT
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 TIRE FLAT message is
displayed. Drive cautiously and check your tire
pressures as soon as you can.

If the transmission uid 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 uid temperature. Driving
aggressively or driving on long hills can cause the
transmission uid 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 uid temperature and allow it to cool to at
least 230°F (110°C). The transmission uid temperature
can be monitored with the gages button on the DIC.SeeAutomatic Transmission Fluid on page 5-20. You
should also check the engine coolant temperature. If it is
also hot, seeEngine Overheating on page 5-24.
If the TRANSMISSION HOT IDLE ENGINE message is
displayed during normal vehicle operation on at
roads, your vehicle may need service. See your
GM dealer for an inspection.
TURN SIGNAL ON:If a turn signal is left on for
three-quarters of a mile (1.2 km), this message will
appear on the display and you will hear a chime. Move
the turn signal/multifunction lever to the off position.
To acknowledge this message, press the RESET button.
UNLATCH HEADER TO MOVE TOP:This message
will display and a chime will sound if you try to lower the
convertible top without rst unlocking the top. Move
the latch handle to unlock the convertible top. See
Convertible Top (Manual) on page 2-57orConvertible
Top (Power) on page 2-64.
3-67

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-39.
4-6

Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may hear
a motor or clicking noise and feel the brake pedal
move a little during a stop, but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
Traction Control System (TCS)
Your vehicle has a traction control system called TCS
that limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin.
The TRACTION SYSTEM ACTIVE message will come
on when the TCS system is limiting wheel spin. See
DIC Warnings and Messages on page 3-54. You
may feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the TCS
system begins to limit wheel spin, the cruise control will
automatically disengage. When road conditions allow
you to safely use it again, you may re-engage the cruise
control. SeeTurn Signal/Multifunction Lever on
page 3-8.
4-8

The SERVICE TRACTION
SYSTEM message and
the TCS warning light will
come on to let you
know if there is a problem
with your TCS system.
SeeDIC Warnings
and Messages on
page 3-54.
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 ACTIVE
HANDLING button. The
DIC will display the
appropriate message when
you push the button.
