Anti-Lock Brake System Warning Light; Stabilitrak Service Light - GMC 2006 Envoy Owner's Manual

Anti-Lock Brake System
Warning Light
If the light stays on, or comes on when you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes, but
you do not have anti-lock brakes. If the regular brake
system warning light is also on, you do not have
anti-lock brakes and there is a problem with your regular
brakes. See Brake System Warning Light on page 3-39
earlier in this section.
The anti-lock brake system 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.

With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds, that is
normal. A chime may also
sound when the light
comes on.
