Brake system warning
•Standard instrument cluster
•Optional instrument cluster
To confirm the brake system
warning light is functional, it will
momentarily illuminate when the
ignition is turned to the ON position (alternatively for some vehicles
when the ignition is moved from the ON position to START position, the
light will momentarily illuminate prior to reaching the START position).
It also illuminates if the parking brake is engaged. If the brake system
warning light does not illuminate as described, seek service immediately.
Illumination after the parking brake is released indicates low brake fluid
level or a brake system malfunction and the brake system should be
serviced immediately by a qualified technician. Refer toBrakesin the
Drivingchapter for more information.
Anti-lock brake system (ABS)
To confirm the anti-lock brake
system (ABS) warning light is
functional it will momentarily
illuminate when the ignition is
turned to the ON position
(alternatively for some vehicles when the ignition is moved from the ON
position to the START position, the light will momentarily illuminate just
prior to reaching the START position). If the light remains on, continues
to flash or fails to illuminate, have the ABS serviced immediately. If the
ABS light remains on, it means the anti-lock brake system has
malfunctioned and is disabled, however, the normal brake system will
still function unless the brake warning light also remains illuminated and
parking brake is off. Refer toBrakesin theDrivingchapter for more
information.
