2007 CHEVROLET CORVETTE brake

Let us say the road is wet and you are driving
safely. Suddenly, an animal jumps out in front of
you. You slam on the brakes and continue braking.
Here is what happens with ABS:
A computer senses that wheels are slowing down.
If one of the wheels is about to stop rolling, the
computer will separately work the brakes at
each wheel.ABS can change the brake pressure faster than
any driver could. The computer is programmed
to make the most of available tire and road
conditions. This can help you steer around the
obstacle while braking hard.
As you brake, the computer keeps receiving
updates on wheel speed and controls braking
pressure accordingly.

Remember: ABS 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 the brakes if that vehicle
suddenly slows or stops. Always leave enough
room up ahead to stop, even though you
have ABS.
Using ABS
Do not pump the brakes. Just hold the brake
pedal down rmly and let anti-lock work for you.
You might 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 ABS, 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
displays on the Driver Information Center (DIC)
when the TCS system is limiting wheel spin.
SeeDIC Warnings and Messages on page 214.
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. See
Turn Signal/Multifunction Lever on page 160.

Adding non-dealer accessories can affect your
vehicle’s performance. SeeAccessories and
Modications on page 319for more information.
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 rst start your vehicle during cold winter
weather and begin to drive away, the message
ACTIVE HANDLING WARMING UP may be
displayed in the DIC. This is normal. You can
acknowledge this message by pressing the RESET
button. The Active Handling System performance
is affected until the message, ACTIVE HANDLING
READY, is displayed in the DIC.
The ACTIVE HANDLING CALIBRATING message
may be displayed in the DIC and the instrument
panel cluster light will be on after exceeding
18 mph (30 km/h) for 10 seconds. The Active
Handling System is off until the ACTIVE
HANDLING READY message is displayed.
This could take up to 15 minutes.The ACTIVE HANDLING message will come on
when the system is operating. SeeDIC Warnings
and Messages on page 214for more information.
You may also feel or hear the system working.
This is normal.
The SERVICE ACTIVE
HANDLING 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.
SeeDIC Warnings and Messages on page 214for
more information.
When this light and the SERVICE ACTIVE
HANDLING SYSTEM message are on, the system
is not operational. Adjust your driving accordingly.
283

Competitive Driving Mode
The driver can select this optional handling mode
by pressing the ACTIVE HANDLING button on
the console two times within a ve second
time period. COMPETITIVE DRIVING MODE will
be displayed in the DIC. Competitive Driving
Mode allows the driver to have full control of the
rear wheels while the Active Handling System
helps maintain directional control of the vehicle by
selective brake application. This involves less
intervention than with both the Active Handling
System and Traction Control Systems on.
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 TRACTION SYSTEM AND ACTIVE
HANDLING-ON message will be displayed
temporarily in the DIC and a chime will be heard.Notice:When traction control is turned off,
or Competitive Driving Mode is active, it
is possible to lose traction. If you attempt to
shift with the rear wheels spinning with a loss
of traction, it is possible to cause damage
to the transmission. Do not attempt to shift
when the rear wheels do not have traction.
Damage caused by misuse of the vehicle
is not covered. See your warranty book for
additional information.
Limited-Slip Rear Axle
Your limited-slip rear axle can give you additional
traction on snow, mud, ice, sand or gravel.
It works like a standard axle most of the time,
but when one of the rear wheels has no traction
and the other does, this feature will allow the
wheel with traction to move the vehicle.
285

Steering in Emergencies
There are times when steering can be more
effective than braking. For example, you come
over a hill and nd a truck stopped in your lane,
or a car suddenly pulls out from nowhere, or
a child darts out from between parked cars
and stops right in front of you. You can avoid
these problems by braking — if you can stop in
time. But sometimes you cannot; there is not room.
That is the time for evasive action — steering
around the problem.
Your vehicle can perform very well in emergencies
like these. First apply the brakes. SeeBraking
on page 278. It is better to remove as much speed
as you can from a possible collision. Then steer
around the problem, to the left or right depending
on the space available.An emergency like this requires close attention and
a quick decision. If you are holding the steering
wheel at the recommended 9 and 3 o’clock
positions, you can turn it a full 180 degrees very
quickly without removing either hand. But you
have to act fast, steer quickly, and just as quickly
straighten the wheel once you have avoided
the object.
The fact that such emergency situations are always
possible is a good reason to practice defensive
driving at all times and wear safety belts properly.
288

Try not to pass more than one vehicle at a time
on two-lane roads. Reconsider before passing
the next vehicle.
Do not overtake a slowly moving vehicle too
rapidly. Even though the brake lamps are not
ashing, it might be slowing down or starting
to turn.
If you are being passed, make it easy for the
following driver to get ahead of you. Perhaps
you can ease a little to the right.
Loss of Control
Let us review what driving experts say about what
happens when the three control systems — brakes,
steering, and acceleration — do not have enough
friction where the tires meet the road to do what the
driver has asked.
In any emergency, do not give up. Keep trying to
steer and constantly seek an escape route or
area of less danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions, and
by not overdriving those conditions. But skids
are always possible.
The three types of skids correspond to your
vehicle’s three control systems. In the braking
skid, the wheels are not rolling. In the steering or
cornering skid, too much speed or steering in
a curve causes tires to slip and lose cornering
force. And in the acceleration skid, too much
throttle causes the driving wheels to spin.
A cornering skid is best handled by easing your
foot off the accelerator pedal.
Remember: Any traction control system helps
avoid only the acceleration skid. If your traction
control system is off, then an acceleration
skid is also best handled by easing your foot off
the accelerator pedal.
291

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you
want the vehicle to go. If you start steering quickly
enough, your vehicle may straighten out. Always
be ready for a second skid if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle
control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road
to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice:If you use your 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 333.
Z06 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: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
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.

Driving in Rain and on Wet Roads
Rain and wet roads can mean driving trouble. On a
wet road, you cannot stop, accelerate, or turn as
well because your tire-to-road traction is not as
good as on dry roads. And, if your tires do not have
much tread left, you will get even less traction. It is
always wise to go slower and be cautious if rain
starts to fall while you are driving. The surface may
get wet suddenly when your reexes are tuned for
driving on dry pavement.The heavier the rain, the harder it is to see.
Even if your windshield wiper blades are in good
shape, a heavy rain can make it harder to see
road signs and traffic signals, pavement markings,
the edge of the road, and even people walking.
It is wise to keep your windshield wiping equipment
in good shape and keep your windshield washer
uid reservoir lled with washer uid. Replace
your windshield wiper inserts when they show
signs of streaking or missing areas on the
windshield, or when strips of rubber start to
separate from the inserts.
{CAUTION:
Wet brakes can cause accidents. They
may not work as well in a quick stop and
may cause pulling to one side. You could
lose control of the vehicle.
After driving through a large puddle of
water or a car wash, apply the brake pedal
lightly until the brakes work normally.
