This light should come on briefly when the
vehicle is turned on. 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 or comes on while
driving, there is a problem with the Electric
Parking Brake (EPB). Take the vehicle to a
dealer as soon as possible. In addition to the

ready to warn if there is a problem. If the light comes on while driving, safely
stop as soon as it is possible and turn off
the vehicle. Then turn on the vehicle again
to reset the system.
If the ABS warning light stays on, or comes
on again while driving, the vehicle needs
service. A chime may also sound when the
light stays on.
If the ABS warning light is the only light on,
the vehicle has regular brakes, but ABS is
not functioning.
If both the ABS warning light and the brake
system warning light are on, ABS is not
functioning and there is a problem with the
regular brakes. See your dealer for service.
See
