'02 AVALON U (L/O 0107) Vehicle skid control system The brake actuator temperature increases during continuous operation of the traction control system or vehicle skid control system such as on slippery roads. If the brake actuator temperature becomes too high while the traction control system or vehicle skid control system is operating, a buzzer will start to sound intermittently to indicate that the traction control system can no longer operate. In this case, immediately stop your vehicle at a safe place. If the system continues to operate, the buzzer sound changes from intermittent to continuous. (The continuous buzzer sounds for about 3 seconds.) At the time the "VSC/TRAC" warning light will come on and the traction control system temporarily stops operating in order to protect the brake actuator. (Although the traction control system does not operate, there is no problem to continue your driving.) The system will be automatically restored after a short time and the "VSC/TRAC" warning light goes out. If the light comes on while driving, the system does not work. However, as conventional braking operates when applied, there is no problem to continue your driving. In the following cases, contact your Toyota dealer: The vehicle skid control system helps provide integrated control of the systems such as anti −lock brake system, traction control, engine control, etc. This system automatically controls the brakes and engine to help prevent the vehicle from skidding when cornering on a slippery road surface or operating steering wheel abruptly. The vehicle skid control activates when the vehicle speed is more than 15km/h (9 mph). You may hear a sound in the engine compartment for a few seconds when the engine is started or just after the vehicle is started. This means that the system is in the self −check mode but does not indicate a malfunction. D The warning light does not come on after the ignition key is turned to "ON". D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving. 138 2002 MY AVALON_U (OM22493U)
