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. This is normal.

If there's
a
problem with
the anti-lock brake system,
this warning light will stay
on. See "Anti-Lock Brake
System Warning Light" in
the Index.
Here's how 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. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.
