Brake System Warning; Light - Buick 2013 Regal Owner's Manual

5-18 Instruments and Controls
The DLC is under the instrument
panel to the next to the steering
wheel. See your dealer if assistance
is needed.
The vehicle may not pass
inspection if:
The malfunction indicator lamp is
on while the vehicle is running.
The vehicle is in ON/RUN for
key access, or Service Only
Mode for keyless access and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
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

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 the brake
system inspected right away.
Metric
The brake system warning light
should come on briefly as the
engine is started. If it does not come
on, have the vehicle serviced by
your dealer.
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
