STARTING AND DRIVING D The light does not come on as described above, or remains on. D The light comes on while driving with the rear differential unlocked. D The light does not come on with the rear differential locked. D The system comes into operation with the rear differential locked. Even if the anti-lock brake system should fail, the brake system will still operate conventionally. But when the "ABS" warning light is on (and the brake system warning light is off), anti-lock brake system is not assisting brake performance so that the wheels could lock up during a sudden brake or braking on slippery road surfaces. Have your vehicle checked by your Lexus dealer as soon as possible. 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 While the "ABS" warning light is on, if either of the following conditions occurs, immediately stop your vehicle at a safe place and contact your Lexus dealer. D The brake system warning light stays on even with the parking brake being released. D The brake system warning light and buzzer come on. In either case, the brakes may not work properly. If they do not work well, depress the brake pedal firmly. 205
