Your Driving and the Road
I f 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.
Antilock Brakes (ABS)
Your vehicle has an advanced electronic braking system that can help you
keep
it
under control.
When you start your vehicle and begin to drive away you may hear a
momentary motor or clicking noise. This
is the ABS system testing itself.
AM415003
Here's how antilock 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 the wheels are slowing down. The computer
separately works the brakes at each front wheel and at the rear wheels. The
antilock system can change the brake pressure faster than any driver could.
The computer
is
programmed
to
make the
most
of available tire
and
road
conditions. You can steer around the obstacle while braking hard.
