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. The brakes may not have time to
cool between hard stops. The 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 vehicle ever loses electrical power while you
are driving, brake normally but do not pump the
brakes. If you do, the pedal may get harder to push
down. If your vehicle loses electrical power, 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, the brake pedal will
be harder to push, and you may experience longer
pedal travel.

vehicle’s performance. See Accessories and

Anti-Lock Brake System (ABS)

Your vehicle has the Anti-Lock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.

When you start your engine and begin to drive
away, ABS will check itself. You may hear a
momentary motor or clicking noise while this
test is going on. This is normal.

If there is a problem
with ABS, this warning
light will stay on.
