Anti-Lock Brake System Warning Light - GMC 2007 Yukon Denali 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.
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.

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 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 234.
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.
