Brake System Warning; Light - Buick LaCrosse Owner's Manual

5-20 Instruments and Controls
The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.

Brake System Warning

Light

The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have your brake
system inspected right away.
Metric
If the vehicle has antilock brakes,
this light should come on when the
vehicle is placed in START. If it does
not, have the vehicle serviced by
your dealer.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal may be harder to push or
it can go closer to the floor. It may
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
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
English
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
