Brake System Warning Light - Buick Lucerne 2010 Owner's Manual

Brake System Warning Light

The vehicle's hydraulic brake system is divided into two
parts. If one part is not working, the other part can still
work and stop the vehicle. For good braking both parts
need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
United States
This light should come on briefly when the engine is
started. If it does not come on then, have it fixed so it
will be ready to warn if there is a problem.
4-36
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.
Canada
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 5 24.

WARNING:
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.
