To ensure that the warning light is working, the symbol is displayed for a short time when the ignition is turned to ON.

If the light doesn't come on then, have it fixed so it will be ready to warn you if there is a problem.

If there is a malfunction of the anti-lock brake system, the symbol will illuminate and ABS Fault will appear on the trip computer display. See your dealer for service. The car's brake system will still operate conventionally, only the anti-lock operation is impaired.

The ABS Fault message will remain until the MODE button on the trip computer is pressed, but the symbol will remain until the problem is fixed.
