Brake System Warning Light - Chevrolet 2011 Impala Owner's Manual

5-20 Instruments and Controls
The vehicle may not pass
inspection if:
The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
The critical emission control
systems have not been
completely diagnosed by
the system. This can happen
if the battery has recently
been replaced or if the battery
has run down. The diagnostic
system evaluates 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, 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 the brake
system inspected right away.
English
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.
When the ignition is on, the brake
system warning light also comes
on when the parking brake is set.
The light stays on if the parking
brake does not fully release. If it
stays on after the parking brake is
fully released, it means the vehicle
has a brake problem.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to
push, or the pedal can go closer
to the floor. It may take longer to
stop. If the light is still on, have
the vehicle towed for service.
