system readiness, 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.
MetricEnglishThis light comes on briefly when the
vehicle is turned on. If it does not
come on then, have it fixed so it will
be ready to warn if there is a
problem.
If the light comes on and stays on,
there is a base 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.
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 or another
system. A message may also
display in the Driver Information
Center (DIC). See Brake System
Messages on page 5-36.
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
in ON/RUN. If it does not come on,
have it fixed so it will be ready to
warn if there is a problem. For
vehicles with the reconfigurable
cluster, this light may not come on
when the vehicle is in ON/RUN.
If this light stays on, there is a
problem with a system on the
vehicle that is causing the parking
brake system to work at a reduced
level. The vehicle can still be driven,
but should be taken to a dealer as
soon as possible. SeeElectric
Parking Brake on page 9-28. If a message displays in the Driver
Information Center (DIC), see
Brake
System Messages on page 5-36.
Antilock Brake System
(ABS) Warning Light
This light comes on briefly when the
engine is started.
If the light does not come on, have it
fixed so it will be ready to warn if
there is a problem.
If the light comes on while driving,
stop as soon as it is safely possible
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.
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 service.

Brake System Warning Light on
page 5-22 andBrake System
Messages on page 5-36.
Lane Keep Assist (LKA)
Light
For some vehicles, this light comes
on briefly while starting the vehicle.
If it does not come on, have the
vehicle serviced.
