Anti-Lock Brake System Warning Light - GMC Sierra Denali Classic 2007 Owner's Manual

Anti-Lock Brake System
Warning Light
That is normal. If the light does not come on then,
have it fixed so it will be ready to warn you if
there is a problem.
With the Anti-Lock Brake
System (ABS), this light
will come on when you
start your engine and
may stay on for
several seconds.
If the light stays on, or comes on when you are
driving, your vehicle needs service. A chime
will sound when the light stays on. If the regular
brake system warning light is not on, you still have
brakes, but you do not have ABS. If the regular
brake system warning light is also on you do
not have ABS and there is a problem with your
regular brakes. In addition to both lights, you
will also hear a chime sound on the first
occurrence of a problem and each time the
vehicle is shut off and then restarted. See Brake
System Warning Light on page 176.
The ABS warning light should come on briefly
when you turn the ignition key to RUN. If the light
does not come on then, have it fixed so it will
be ready to warn you if there is a problem.
