INSTRUMENTS AND CONTROLS 131
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.
MetricEnglish
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 you if there is a
problem.
If the light comes on and stays on,
there is a brake problem.
{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 the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed for
service.
Electric Parking Brake
Light
MetricEnglish
This light comes on when the parking
brake is applied. If the light continues
flashing after the parking brake is
released, or while driving, there is a
problem with the Electric Parking Brake system. A message may also
display in the Driver Information
Center (DIC).
If the light does not come on,
or remains flashing, see your dealer.
Service Electric Parking
Brake Light
On some vehicles the service electric
parking brake light should come on
briefly when the vehicle is started.

not come on when the vehicle is
started.

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.
If both the ABS and the brake system
warning light are on, the vehicle's
antilock brakes are not functioning
and there is a problem with the
regular brakes. See your dealer for

maintenance schedule for changing
engine oil.
This light should come on briefly as
