Antilock Brake System (Abs) Warning Light - GMC Acadia 15919282 Owner's Manual

This light may also come on due
to low brake fluid. See Brakes
on page 5-27 for more information.
When the ignition is on, the brake
system warning light will also come
on when the parking brake is set.
The light will stay on if the parking
brake does not release fully. If it
stays on after the parking brake is
fully released, it means there is a
brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
Make sure the parking brake is fully
released. The pedal may be harder
to push or, the pedal may go closer
to the floor. It may take longer to
stop. If the light is still on, have
the vehicle towed for service.
See Towing Your Vehicle on
page 4-20.

CAUTION
The brake system might not be
working properly if the brake
system warning light is on. Driving
with the brake system warning light
on can lead to a crash. If the light
is still on after the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed
for service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes
on briefly when the engine is started.
Instrument Panel
If the light does not come on, have
it fixed so it will be ready to warn
if there is a problem.
If the ABS light stays on, turn the
ignition off. If the light comes on while
driving, stop as soon as it is safely
possible and turn the ignition off.
A chime may also sound when the
light comes on steady. Then start
the engine again to reset the system.
If the ABS light stays on, or comes
on again while driving, the vehicle
needs service. If the regular brake
system warning light is not on, the
vehicle still has brakes, but not
antilock brakes. If the regular brake
system warning light is also on,
the vehicle does not have antilock
brakes and there is a problem with
the regular brakes. See Brake
System Warning Light on page 3-38.

Information Center (DIC), see
