Pontiac 2008 grand prix Automobile User Manual


 
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 might 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’s engine ever stops while you are
driving, brake normally but do not pump the brakes.
If you do, the pedal could get harder to push down.
If the 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 can take longer
to stop and the brake pedal will be harder to push.
Adding non-dealer/non-retailer accessories can
affect your vehicle’s performance. See Accessories
and Modifications on page 5-3.
Antilock Brake System (ABS)
Your vehicle might have the Antilock Brake
System (ABS), an advanced electronic braking
system that will help prevent a braking skid.
If your vehicle has ABS,
this warning light on
the instrument panel will
come on briefly when
you start your vehicle.
When you start the engine, or when you begin to
drive away, ABS will check itself. You might hear a
momentary motor or clicking noise while this test
is going on, and you might even notice that the brake
pedal moves or pulses a little. This is normal.
Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you.
You slam on the brakes and continue braking.
Here is 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 wheel.
