Antilock Brake System

Warning Light

If the light stays on, or comes on when you are
driving, your vehicle needs service. If the brake
or low air warning light is not on, you still
have brakes, but you do not have the antilock
brake feature. If the brake and/or low air warning
light is on, you do not have antilock brakes
and there is a problem with your regular brakes.
See Brake System Warning Light on page 124 and
Antilock Brake System (ABS) on page 154 for
more information.
This light will come on
briefly when you start
the engine, then it
will turn off. This
is normal.

Trailer Antilock Brake System

Warning Light
When this light comes on and stays on, it means
there is something wrong in the trailer Antilock
Brake System (ABS). Have the system repaired
immediately.
If an ABS equipped trailer is not connected, this
light is not functional.
If your vehicle is
connected to a trailer
with antilock brakes, this
light should come on
briefly, as a check, when
you turn on the ignition.
