'03 4Runner_U (L/O 0211) Rear height control air suspension "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 "ON". 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 hill-start 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 hill-start assist control system stops operating temporarily in order to protect the brake actuator. (Although the hill-start 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: D The warning light does not come on after the ignition key is turned to "ON".
