'01 4Runner_U (L/O 0008) Brake pad wear limit indicators Either of the following conditions do not indicate the malfunction. For an explanation of this system's warning light, see "Service reminder indicators and warning buzzers" in Section 1−5. 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. 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). The brake pad wear limit indicators on your disc brakes give a warning noise when the brake pads are worn to where replacement is required. If you hear a squealing or scraping noise while driving, have the brake pads checked and replaced by your Toyota dealer as soon as possible. Expensive rotor damage can result if the pads are not replaced when necessary. 200 2001 4RUNNER (OM35768U)
