0 (Automatic Overdrive): This
position is. for normal driving. If you
need more power for passing, and
you're:
Going less than about 35 mph
(56,lUn/h), push your accelerator
pedal
about halfway down.
Going about 35 mph (56 ldh) or
more, push the accelerator all .the way
down.
You'll shift down to the next geai and
have more power.
D (Third Gear): This is like m, but
you never go into Overdrive.
Here-are
some times you might choose
D instead of a:
When driving on hilly, winding roads.
When going down a steep hill.
2 (Second Gear): This position gives
you more. power but lower -fuel
economy.
You can use 2 on hills. It can
help control your speed as yuu go down
steep mountain roads, but then you
would also want to use your brakes off
and on..
1 (First Gear): This position gives you
even more power (but lower fuel
economy)
than 2. You can use it on
very steep hills, 01 in deep snow or
mud. If
the selector lever is put in 1, the
transmission won't shift into first- gear
until the vehicle is going slowly enough.

Braking
Braking action involves perception
time .and reaction: time.
First, you have.to .decide to push on the
br&i pedal. That’s perception time.
Then you have to bring up your foot
and do it. That’s reaction time.
Average reaction time .is about 3/4 -of, a
second. But that’s only an average. It
might be less with one driver and- as
long as two or three seconds or mQre
with another. Age, physical condition,
alertness, coordination, and eyesight all
play a part. So do alcohol, drugs and
frustration. But even in 3/4 of a second, a
vehicle moving at
60 mph (100 Wh)
travels 66 feet (21) m). That could be a
lot
of distance in an emergency, so
keeping enough space between your
vehicle and others
is important.
And, of course, actual stopping
distances vary greatly with the surface
of the road (whether it’s pavement or
gravel) ; the conditian uf the road (wet,
dry, icy); tire tread; arid the. condition of
your brakes.
Most drivers;treat.their brakes with
care. Some, however, overwarlc the
braking system with poor driving habits.
. Avoid needless heavy braking. Some
people. drive in spurts-heavy
acceleration followed.
by heavy
braking-rather- than lreeping pace
with traffic, This.is a mistake. Your
brakes may
not have he to cool
between hard.stops. Your brakes will
wear out much faster if you do a lot of
heavy braking.
Don’t “ride” the brakes by letting
your left
foot rest lightly on the hake
pedal while driving.

You might not be able to-stop .your
vehicle in time -to avoid an accident.
If you “ride” your bides,. they w3’i

pedal force to slow you down.
Avoid “riding” the’brakes.
INoTIcE .
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’re
driving, brake normally but don’t
pump your brakes. If you do, the
pedal may get harder to push down. If
your engine stops, you wilI still have
some power brake assist. But you will
use it when you brake. Once the
power assist is used up, it may take
Homgez ta stop and the brake pedal will
be harder to push.
Anti-L~ck Brakes (ABS)
Your Corvette has an advanced
electronic braking system that will help
prevent skidding.
This light on the instrument panel will
go on when you start your vehicle.
See the Index under Anti-Lock Brake
System Light.

Anfi-Lock Brakes (CONT.)
Here's haw anti-lock works. Let's say
the road is wet. You're driving safely.
Suddenly an animal jumps out in front
of ,you.
You slam on the brakes. ,Here's what
happens with ABS .
A computer senses that wheels are
slowing down. The computer separately
works
the brakesat each front wheel
and at the .rear wheels.
e 74
The anti-lock system can change the
brake pressure faster than
any driver
could. The computer
is programmed to
make the most of available tire alid road
conditions.
You can steer around the obstacle while
braking hard.
As you brake, your computer keeps
receiving
updates on wheel speed ad
controls braking pressure accordingly.
CAUTION

Downloaded from www.Manualslib.com manuals search engine P TO Use Anti-L.ock:
Don't pump the brakes. Just hold the
brake pedal downand let anti-lock
work for you. You may feel the brake
pedal
vibrate, or you -may notice some
noise,
but thi.s is normal.
When the ABS is active, the ABS
ACTIVE light- conies on to-indicate luw
traction conditions.
Adjust your -driving
accordingly.
When
you start your vehicle and begin
to drive away, you may hear a
momentary motsr Qr .clicking, noise-and
you. my even notice that, yow bmke
pedd -moves a little while this is going
on.
This is the ABS test-ing itself. You-
may also hear and feel this durihg a
hard stop.
Corvette ASR (Acceleration SIip
R.egulati0.n) System
Yo& vehicle has an ASR system that
limits wheel
spin. This is especially
useful in slippery road conditions. The
ASR system works at all speeds. It
limits
wheel spin by reducing englne
torque
by cLusing the throttle and
managing
sp'ark and .applyiag the rear
brakes. You may €&el the system
working., .or
you may notice some noise,
but this is normal.

To turn the system off, press the button
located above the headlight switch. The
ASR OFFlight will come on and stay

OFF button, the ASR system will not
be turned off until the rear wheels
stabilize with the front wheels.
Any

on again. The ASR OFF light
should
go off. The ASR system
automatically comes
on whenever you
start your vehicle.
NOTE: When ASR is active the cruise
CQntrOl will go off.
Disc Brake Wear lndicators
Your Corvette has four-wheel disc
brakes. Disc brake pads have built-in
wear indicators that make
a high-
pitched warning sound when the brake
pads are worn and new pads are needed.
The sound may come and
go or be
heard
aIl the time your vehicle is moving
(except when you
are pushing on the
brake pedal firmly). Some
driving conditions or climates
may cause a brake squeal when
the
brakes are first applied or lightly
applied. This does not mean
something
is wrong with your brakes.
Brake linings should always be replaced
as complete axle sets.

Braking In Emergencies
Use your .anti-lock braking system when
you-need to. With,anti-lock, you can
steer and brake at the same time.. In
many.emagencies, steering can help
you more than even the very best
braking;.
