GMC 1999 Jimmy Owner's Manual page 203

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'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.
-
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.
