Brake System Warning; Light - GMC Savana 2011 Owner's Manual

The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
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
could be a brake problem. Have the
brake system inspected right away.

This light should come on briefly
when ignition key is turned to
ON/RUN. If it does not come on,
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. See
Parking Brake on page 9 34 for
more information. 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.
