STARTING AND DRIVING When the "ABS" warning light is on (and the brake system warning light is off), the anti-lock brake system and/or the traction 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 and/or the traction control system do/does not operate so that the wheels could lock up during a sudden braking or braking on slippery road surfaces. If either of the following conditions occurs, 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. D The light does not come on when the ignition key is turned to the "ON" position, or remains on. D The light comes on while you are driving. A warning light turning on briefly during operation does not indicate a problem. Drum-in-disc type parking brake system Your vehicle has a drum-in-disc type parking brake system. This type of brake system needs bedding-down of the brake shoes periodically or whenever the parking brake shoes and/or drums are replaced. Have your Lexus dealer perform the bedding-down. CAUTION If the "ABS" warning light remains on together with the brake system warning light, immediately stop your vehicle at a safe place and contact your Lexus dealer. In this case, not only the anti-lock brake system will fail but also the vehicle will become extremely unstable during braking. 184
