2002 CHEVROLET VENTURE brake light

2-124 How the System Works
If the rear park aid disable switch is not on, the rear
parking assist turns on automatically when the shift
lever is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When the system
turns on, the three lights on the display will illuminate
for 1.5 seconds to let you know that the system is
working. Rear parking assist senses how close your
vehicle is to an object. The distance is determined by the
four ultrasonic sensors located on the rear bumper.
When shifting into REVERSE (R) and an object is
detected, one of the following will occur:

Amber/amber/red lights flashing and
continuous chime 1 ft. (0.3 m). . . . . . . . . . . . . . . . .

Amber/amber/red lights and
continuous chime 20 in. (0.5 m). . . . . . . . . . . . . . . .

Amber/amber lights 40 in. (1.0 m). . . . . . . . . . . . . .

Amber light 5 ft. (1.5 m). . . . . . . . . . . . . . . . . . . . .
A chime will sound the first time an object is detected,
if the object is between 20 inches (0.5 cm) and
5 feet (1.5 m) away.
Rear parking assist can detect objects 3 inches (7.6 cm)
and wider, and at least 10 inches (25.4 cm) tall, but it
cannot detect objects that are above liftgate level. In
order for the rear sensors to recognize an object, it must
be within operating range.If the rear parking assist system is not functioning
properly, the display will flash red, indicating that there is
a problem, unless the disable switch is on. The light will
also flash red when the vehicle is shifting into
REVERSE (R), if a trailer was attached to your vehicle,
or if a bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle. The light
will continue to flash whenever in REVERSE (R) until
your vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
It will also flash red if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush or the system may not work
properly. If after cleaning the rear bumper and driving
forward at least 15 mph (25 km/h), the display continues
to flash red, see your dealer.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.

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'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 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, or when you 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 or pulses a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.

4-9
Remember: Anti-lock doesn't 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 won't 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
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may feel a
slight brake pedal pulsation or notice some noise, but
this is normal.
Braking in Emergencies
With anti-lock, 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 (Option)
Your vehicle may have a traction control system that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine power
to limit wheel spin.
The TRACTION ACTIVE message will come on when
the traction control system is limiting wheel spin. See
ªTRACTION ACTIVE Messageº in the Index. You may
feel or hear the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. See ªCruise Controlº in
the Index.

4-19
Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can't, try to slow down before you hit them.
CAUTION:
Wet brakes can cause accidents. They won't 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 your brake pedal lightly until
your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you're
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.

NOTICE:
If the other system isn't a 12-volt system with a
negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic transaxle
in PARK (P) or a manual transaxle in NEUTRAL
before setting the parking brake.
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn off the
radio and all lamps that aren't needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (
-) terminal locations on
each vehicle.
You will not need to access your battery for jump
starting. Your vehicle has a remote positive (+) jump
starting terminal for that purpose.

When your brake fluid falls to a low level, your brake
warning light will come on. See ªBrake System Warning
Lightº in the Index.
What to Add
When you do need brake fluid, use only DOT
-3 brake
fluid. Refer to ªRecommended Fluids and Lubricantsº
in the Index. Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral
-based oil, such as engine
oil, in your brake system can damage brake
system parts so badly that they'll have to be
replaced. Don't let someone put in the
wrong kind of fluid.

If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid on
your vehicle. If you do, wash it off immediately.
See ªAppearance Careº in the Index.

6-34 Brake Wear
Your vehicle has front disc brakes and rear drum 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 all the time your vehicle
is moving (except when you are pushing on the brake
pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in the
proper sequence to GM torque specifications.
Your rear drum brakes don't have wear indicators, but if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected immediately. Also, the rear
brake drums should be removed and inspected each time
the tires are removed for rotation or changing. When
you have the front brake pads replaced, have the rear
brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in Section 7 of this manual
under Part C ªPeriodic Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
