Antilock Brake System (Abs) Warning Light - Buick 2009 Lucerne Owner's Manual

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means there is a brake problem.
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.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or
the pedal could go closer to the floor. It could take
longer to stop. Try turning off and restarting the vehicle
one or two times, if the light is still on, have the
vehicle towed for service. See Towing Your Vehicle
on page 4-23.
Antilock Brake System (ABS)
Warning Light
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
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. 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 3-40.
For vehicles with a Driver Information Center (DIC),
see DIC Warnings and Messages on page 3-60 for all
brake related DIC messages.
For vehicles with the
Antilock Brake System
(ABS), this light comes on
briefly when the engine
is started.
