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 Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and 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 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.

yellowblue
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 hear a
motor or clicking noise and feel the brake pedal move a
little during a stop, but this is normal.
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 will
come on when the TCS system is limiting wheel spin.
See ªTRACTION SYSTEM 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 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 ªCruise Controlº in the Index.)
The SERVICE TRACTION
SYSTEM message and the
TCS warning light will
come on to let you know if
there's a problem with your
TCS system. See
ªSERVICE TRACTION
SYSTEM Messageº in
the Index.
