Low 7ire Pressure Warning Light
(OPTION)
The LTPWS has a sensor 'on each road
wheel that transmits-to
a receiver on the
instrument panel.
The system operates
on a radio frequency subject
to Federal
Communications Cbmission
(FCC)
Ruks.
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following
two conditions: (1) This
device may not cause harmful
interhence,
and (2) This device.must
accept
any interhence received,
including interference that-may cause
undesired operation.
Changes or modifications to- this system
by other than an authorized service
facility could void authorization to use
this equipment.
The Low Tre Pressure Warning System
(LTPWS) monitors the
air pressure in
each road tire (except the spare tire)
while the car is being driven. The
LTFWS will not warn the driver if a tire
is
already flat before the vehicle is started.
This light comes on whenever a tire
pressure
goes below 25 psi (I 75 Ha) in
any road tire while your Corvette is being
driven.
You must drive the car faster than
25 mph (40 km/h) and for more than 2
miles (4 h) -for the system to work
properly.
The Low Tire Pressure Warming
Light also warns you if any of the
system's comp.onents-are not working
properly. The
LOW TIRE PRESSURE
light will remain on until the ignition is
turned
off. This will also reset the system.
When the LOW TIRE PRESSURE
fight comes on, check the tire -pressure
.in
all four road tires as soon as you can,
using the
tire pre:ssure gage.provided in
thesenter console. Adjust the tire
pressure as needed to those shown on
the Tire-Loading Information label
10-cated
on the driver's door, The LOW
TIRE PRESSURE light may come on
if your vehicle is close to aaother
vehicle that has
a Low Tire Pressure
Warning System
and has a tire-with low
pressure.
The LTPWS sensor is directly opposite
the valve stem on the tire. Take extreme
care when servicing or
having your tires
serviced. The sensors may not work
properly
if damaged.
If you need to take the tire off the wheel,
do it at a
90" angle from the valve stem.

This light c0me.s on when the-anti-lo-clr
brake system is engaged to prevent
wheel lock when
braking. You may hear

through a diagnostic test. This light will
also
come on as a test for .about two
seconds
when the engine is ‘started.
Service ABS Light
This light will come on as a test for
.about- two seconds when the engine is

If it stays on, - or comes an while you are
driving, carefully stop your vehicle as
.soon as you can and turn the ignition
off. Then start the engine to restart the
system.
If the SERVICE ABS light
stays
on, or it comes on again while you
are driving; the anti-lock system needs
service. Unless the BRAKE warning
light is also on,. you will still have
brakes, but not ABS.

You slam on the brakes. ,Here's what
happens with ABS .
A computer senses that wheels are

The anti-lock system can change the
brake pressure faster than
any driver
could. The computer
is programmed to

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

This is the ABS test-ing itself. You-
may also hear and feel this durihg a

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.

Corvette ASR System (CONT.)
The ASR system comes on when the
ignition is -turned
on and operates at all
speeds. When your ASR system is
operating, the
ASR ACTIVE indicator
on the Driver Information Center
(DIC)
will come on. It indicates the system
has detected excess wheel slip, like the
conditions found on slippery-roads.
Also, when ASR is active, the cruise
control
will be automaticaIly turned off
The SERVICE ASR warning light lets
you know
when there is a problem with
your ASR system. When this light is on,
you have no-automatic wheel spin
protection. Adjust your driving
accordingly, See the
Index under
Service ASR Light..
Turning the ASR System Off
To limit wheel spin, especially in
slippery road conditions, you should
always leave your ASR. system on. But
you can turn the ASR system off if you
ever need to. ASR OFF means the
controller is passive, but still

speed informauon.

automatically comes

start your vehicle.
NOTE: When ASR is active the cruise

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.

steering Tips-Dtiving on Curves
It's important to tale curves at a
reasonable
speed.
A lot of the "driver lost control"
accidents mentioned
on. the news
happen on .curves. .Here's why:
Experienced driver
or beginner, each of
us is subject to the same laws of physics
when
driving on'curves; The.;traction of
the tixes against the road surface makes
it possible
for the vehicle to change its
path when you turn the front wheels. If
there's no traction, inertia will keep the
vehicle going in the same direction. If
yuu"ve mer tried to steer a vehicle on
wet ice> you:U understand this.
The traction you can get in a curve
depends on the condition of your tizies
and
the road surface, the angle at which
the-curve
is banked, and your speed,
While you're in
a curve, speed is the one
factor you can control.
Suppose you're steering through. a. sharp
a.xve. Then you suddenly acwlerate. If
excess wheel spin is detected, ASR will
reduce erigine torque to the wheels. Lf
your ASR system is off, those two
control systems-steering and
acceleration-can ovGrwhelm those
i places where-the tires meet the road and
~ make you lose control.
1 What should you do if this ever
happens? Let
up on the accelerator
pedal, steer
the vehicle the way you
want it to go, and slow down.
