'06 TUNDRA_U (L/O 0508) The brake actuator temperature increases during the traction control system, vehicle stability control system or "AUTO LSD" system operating. 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 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 slip indicator 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, it is no problem to continue driving.) The system will be automatically restored after a short time and the slip indicator light goes off. "VSC TRAC" warning light This light warns that there is a problem somewhere in the following. D Traction control system D Vehicle stability control system D "AUTO LSD" system When the system is normal and the ignition key is turned to "ON", the light will come on and will go off after a few seconds. Without tachometer 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. If the "VSC TRAC" warning light and slip indicator light comes on while driving, the traction control system does not work. However, as the brakes operate normally when applied, it is no problem to continue your driving. With tachometer 200 2006 TUNDRA from Oct. '06 Prod. (OM34458U)
