06 06.12 If either of the following conditions occurs, this indicates a malfunction somewhere in the components monitored by the warning light system. Contact your Toyota dealer as soon as possible to service the vehicle. 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 Toyota dealer perform the bedding−down. BRAKE ASSIST SYSTEM When you slam the brakes on, the brake assist system judges as an emergency stop and provides more powerful braking for a driver who cannot hold down the brake pedal firmly. When you slam the brakes on, more powerful braking will be applied. At this time, you may hear a sound in the engine compartment and feel the vibrations of the brake pedal. This does not indicate a malfunction. The brake assist system becomes operative after the vehicle has accelerated to a speed in excess of approximately 10 km/h (6 mph). It stops operating when the vehicle decelerates to a speed below approximately 5 km/h (3 mph). For an explanation of this system's warning light, see "Service reminder indicators and warning buzzers" on page 164 in Section 1−6. 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. 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 Toyota dealer. In this case, not only the anti−lock brake system will fail but also the vehicle will become extremely unstable during braking. 348 2007 SEQUOIA from Sep. '06 Prod. (OM34457U)
