This light is located above the climate controls in the center of the instrument panel.

If your vehicle is connected to a trailer with anti-lock 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 anti-lock brake system. Have the system repaired immediately.

If an anti-lock brake system equipped trailer is not connected, this light is not functional.
