GMC 2005 Savana - Manual (Page 145)

Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on for
several seconds. That’s
normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes. If the regular brake
system warning light is also on, you don’t have anti-lock
brakes and there’s a problem with your regular
brakes. See Brake System Warning Light on page 3-29
for more information.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If
the light doesn’t come on then, have it fixed so it will be
ready to warn you if there is a problem.
StabiliTrak Not Ready Light
If your vehicle has the
StabiliTrak
® system, this
light will come on
according to the
description table for the
StabiliTrak
® system.
For more information, see StabiliTrak ® System on
page 4-9.
You will hear three chimes if the light turns on and one
chime if the light turns off.
