Brake System Warning
Light
Your vehicle’s hydraulic brake
system is divided into two parts. If
one part is not working, the
other part can still work and stop
you. For good braking, though, you
need both parts working well.
If the warning light comes on, there
is a brake problem. Have your
brake system inspected right away.If your vehicle has anti-lock brakes,
this light should come on when
you turn the key to START. If it does
not come on, have it xed so it
will be ready to warn you if there is
a problem.
When the ignition is on, the brake
system warning light will also
come on when you set your parking
brake. The light will stay on if
your parking brake does not release
fully. If it stays on after your
parking brake is fully released, it
means you have a brake problem.
If the light comes on and Brake
message comes on the Driver
Information Center (DIC), while you
are driving, pull off the road and
stop carefully. You may notice that
the pedal is harder to push or
the pedal may go closer to the oor.It may take longer to stop. If the
light is still on, have the vehicle
towed for service. SeeAntilock
Brake System (ABS) Warning Light
on page 4-17andTowing Your
Vehicle on page 9-84.
{CAUTION
Your brake system may not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to an
accident. If the light is still on
after you have pulled off the
road and stopped carefully,
have the vehicle towed for
service.
The Brake message will remain until
3(Trip/Fuel) or8(Enter) are
pressed, but the brake light will
remain until the problem is xed. See
