brake is released, or while driving,
there is a problem with the Electric
Parking Brake system or another
system. A message may also
display in the Driver Information
Center (DIC). See Brake System
Messages on page 5-33. If the light does not come on,
or remains flashing, see your dealer.
Service Electric Parking
Brake Light
This light should come on briefly
when starting the vehicle. If it does
not come on, have it fixed so it will
be ready to warn if there is a
problem.
If this light stays on, there is a
problem with the Electric Parking

reduced level. The vehicle can still
be driven, but should be taken to a
dealer as soon as possible. See the

fixed so it will be ready to warn if
there is a problem. If the light comes on while driving,

and turn off the vehicle. Then start
the engine again to reset the
system. If the ABS light stays on,
or comes on again while driving, the
vehicle needs service. A chime may
also sound when the light comes on
steady.
If the ABS light is the only light on,
the vehicle has regular brakes, but
the antilock brakes are not
functioning.

functioning and there is a problem
with the regular brakes. See your
dealer for service.
