Anti-lock Brake System (ABS)
Warning Light
This light will come on
briefly when you start the
engine, then it will turn
off. This is normal.
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 3-32
and Antilock Brake System (ABS) on page 4-5 for
more information.
Trailer Antilock Brake System
Warning Light
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.
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.
