2006 BUICK LACROSSE warning

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on and the parking brake
is not applied, there is a brake problem. Have your
brake system inspected right away.
This light should come on
briey when you turn the
ignition key to RUN.
If it does not come on then, have it xed so it will be
ready to warn you if there is a problem.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on if your parking brake does not 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 you are driving, a chime will
sound and you should 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 oor. It may take longer to
stop. If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-36.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
