'06 TUNDRA_U (L/O 0508) Make sure the "AUTO LSD" indicator light comes on under the above condition when you use the "AUTO LSD" system. The slip indicator light blinks when the system is controlling the spinning of the rear wheels. The "AUTO LSD" and slip indicator lights come on for a few seconds when the ignition key is turned to "ON". If the indicator lights does not come on when the ignition key is turned to "ON", contact your Toyota dealer. 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 "AUTO LSD" 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 "AUTO LSD" system temporarily stops operating in order to protect the brake actuator. (Although the "AUTO LSD" 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.
