STARTING AND DRIVING "ABS" warning light 31E068 The light comes on with the ignition key turned to "ON". If the anti-lock brake system and the brake assist system work properly, the light goes out after a few seconds. Thereafter, if either of the systems malfunctions, the light comes on. When the "ABS" warning light is on (and the brake system warning light is off), the anti-lock brake system, the brake assist system, the traction control system and/or the vehicle skid control system do/does not operate, but the brake system still operates conventionally. When the "ABS" warning light is on (and the brake system warning light is off), the anti-lock brake system does not operate so that the wheels could lock up during a sudden braking or braking on slippery road surfaces. If the following conditions occur, this indicates a malfunction somewhere in the parts monitored by the warning light system. Contact your Lexus dealer as soon as possible to service the vehicle.
