05 02.25 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. Any of the following conditions may occur, but do not indicate a malfunction: D With rear differential lock: The light comes on with rear differential locked. At this time, the anti- lock brake system, the brake assist system, the vehicle stability control system, the traction control system, the downhill assist control system and the hill- start assist control system do not operate. 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. Vehicles with the vehicle stability control system- 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 147 in Section 1- 6. D The light may stay on for about 60 seconds after the ignition key is turned to the "ON" position. It is normal if it turns off after a while. D Depressing the brake pedal repeatedly may turn on the light. It is normal if it turns off after a few seconds. 264 2005 TACOMA from Mar. '05 Prod. (OM35862U)
