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 are driving, brake
normally but do not 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 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 is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-39.

The SERVICE TRACTION
SYSTEM message and
the TCS warning light will
come on to let you
know if there is a problem
with your TCS system.
SeeDIC Warnings
and Messages on
page 3-54.
When this light and the SERVICE TRACTION SYSTEM
message are on, the system will not limit wheel spin.
Adjust your driving accordingly.The TCS system automatically comes on whenever you
start your vehicle. To limit wheel spin, especially in
slippery road conditions, you should always leave the
system on. But you can turn the TCS system off if
you ever need to.
To turn the system off,
press the button located
on the console. You
can turn the system on or
off at any time by
pressing the ACTIVE
HANDLING button. The
DIC will display the
appropriate message when
you push the button.
