Brake System Warning Light
(a)(!)
BRAKE
Your Buick’s hydraulic
brake system is divided into
two parts. If one part isn’t
working, the other part can
still work and stop you. For
good braking, though, you
need both parts working well.
If the warning light goes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on as you start the vehicle.
If it
doesn’t come on then, have it fixed
so it will be ready to
warn you if there’s a problem. This
light will also come on when you set your parking
brake, and will stay on if your parking brake doesn’t
release fully. If it stays
on after your parking brake is
fully released, it means you have a brake problem. If the
light comes on while driving, pull off the road and stop
carefully. You may notice that the pedal is 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”
in the Index.)
A CAUTION:
Your brake system may not be working properly
if the brake warning light is on. Driving with the
brake warning light on can lead to an accident.
If
the light is still on after you’ve pulled off the road
and stopped carefully, have the vehicle towed fo
service.
