'03 4Runner_U (L/O 0305) Hill-start assist control system "VSC TRAC" warning light When the system is normal and the ignition key is turned to "ON", the warning light will come on and will go off after a few seconds. It is not a malfunction that the warning light may stay on for 60 seconds after the ignition key is turned to the "ON" position. Depressing the brake pedal repeatedly may turn on the light. It is normal if it goes out after a few seconds. The brake actuator temperature increases during continuous operation of the above mentioned system on such as slippery roads. If the brake actuator temperature becomes too high while any of the systems is operating, a buzzer will start to sound intermittently to indicate that the downhill assist control system can no longer operate. In this case, stop your vehicle immediately 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 this time, the "VSC TRAC" warning light will come on and the downhill assist control system stops operating temporarily in order to protect the brake actuator. (Although the downhill assist control system does not operate, it 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 warning light comes on while driving, the system does not work. However, as normal braking operates when being applied, it is no problem to continue your driving. In the following cases, contact your Toyota dealer: The hill-start assist control system assists you in starting to move up a steep or slippery hill. When you start to move up the hill slope, the system helps to prevent the vehicle from rolling backward in the interval while you move your foot from the brake pedal to the accelerator pedal. CAUTION D Do not rely excessively on the hill- start assist control system. The vehicle may not be able to start smoothly on road surfaces or off- road surfaces such as extremely steep slopes or icy roads, on which sliding can occur very easily. D The warning light does not come on after the ignition key is turned to "ON". D Do not use the hill-start assist control system to stop the vehicle. This system is not designed as a function for stopping the vehicle on a uphill slope. D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving. 155 2003 4RUNNER from Apr. '03 Prod. (OM35820U)
