Antilock Brake System (Abs) - Chevrolet Silverado 2007 Owner's Manual

If your vehicle's engine ever stops while you are
driving, brake normally but do not pump the
brakes. If you do, the pedal may 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 may take longer to stop and the brake pedal
will be harder to push.
Adding non-GM accessories can affect your
vehicle's performance. See Accessories and
Modifications on page 494.

Antilock Brake System (ABS)

Your vehicle has the Antilock Brake System
(ABS), an advanced electronic braking system that
will help prevent a braking skid.
When you start the engine and begin to drive
away, ABS will check itself. You might hear
a momentary motor or clicking noise while this test
is going on. This is normal.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there is a DRP
problem, both the brake and ABS warning lights
come on accompanied by a 10-second chime. The
lights and chime will come on each time the
ignition is turned on until the problem is repaired.
See your dealer/retailer for service.
If there is a problem
with ABS, this warning
light will stay on.

System Warning Light
