If this warning light stays on after
the engine is started, the parking
brake may still be set or there could
be a brake problem. Refer to
Parking Brake on page 9‑33to see
if it is set. If the parking brake is not
set, have the brake system
inspected right away.
If the light comes on while driving
and a CHECK BRAKE FLUID
message shows on the DIC, pull off
the road and stop carefully. The
pedal may be harder to push or the
pedal may go closer to the floor.
It may take longer to stop. If the
light is still on, have the vehicle
towed for service. See Towing the
Vehicle on page 10‑79 andBrake
System Messages on page 5‑35 for
more information.Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light on
page 5‑20.
One-to-Four Shift Light
(Manual Transmission)
When this light comes on, the
vehicle can only be shifted from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into
4 (Fourth) to turn off this feature.
This helps the vehicle get the best
possible fuel economy.
After shifting to 4 (Fourth), the
vehicle can be downshifted to a
lower gear.

9-6 Driving and Operating
Remember: Antilock brakes help
avoid only the braking skid.
Racing or Other
Competitive Driving
Racing or competitive driving may
affect the vehicle warranty. See the
warranty book before using the
vehicle for racing or other
competitive driving.
Notice:If you use the vehicle for
racing or other competitive
driving, the engine may use more
oil than it would with normal use.
Low oil levels can damage the
engine. For information on how to
add oil, see Engine Oil on
page 10‑13.
Z06, ZR1, manual transmission
Grand Sport Coupe and 427
Convertible only: Be sure to
check the oil level often during
racing or other competitive
driving and keep the level at or
near the upper mark that shows
the proper operating range on the
engine oil dipstick. Except Z06, ZR1, manual
transmission Grand Sport Coupe
and 427 Convertible : Be sure to
check the oil level often during
racing or other competitive
driving and keep the level at or
near 1 L (1 qt) above the upper
mark that shows the proper
operating range on the engine oil
dipstick. After the competitive
driving, remove excess oil so that
the level on the dipstick is not
above the upper mark that shows
the proper operating range.
Z06, ZR1, manual transmission
Grand Sport Coupe and 427
Convertible Only: For racing or
competitive driving, it is
recommended that the brake fluid
be replaced with a high performance
brake fluid that has a dry boiling
point greater than 279°C (534°F).
After conversion to the high
performance brake fluid, follow the
brake fluid service
recommendations outlined by the
fluid manufacturer. Do not use
silicone or DOT-5 brake fluids.
Z06, ZR1, and manual transmission
Grand Sport Coupe Only: For racing
or competitive driving, it is
recommended that the loading of
the vehicle be limited to the driver
only, with no other cargo, and that
tires be inflated to 180 kPa (26 psi)
for a maximum speed of 230 km/h
(143 mph).
If the vehicle is a Z06, ZR1,
or manual transmission Grand Sport
Coupe and 427 Convertible model,
it has greaseable outer ends on
both of the rear toe-links. Under
normal use, lubrication should be
performed as described in the
maintenance schedule. See
Maintenance Schedule on
page 11‑3
andRecommended
Fluids and Lubricants on
page 11‑12. If using the vehicle for
racing, lubrication should be
performed at the end of each racing
day. See your dealer for lubrication
and make sure any needed repairs
are made at once. Proper
procedures for performing these

Hydroplaning
Hydroplaning is dangerous. Water
can build up under the vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When the vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑52.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving —scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
