'05 4Runner_U (L/O 0409) The brake actuator temperature increases during continuous operation of the "AUTO LSD" system, the traction control system and the vehicle stability control system such as on 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 "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. 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 "AUTO LSD" system does not work. However, as the brakes operate normally when 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". "VSC TRAC" warning light This light warns that there is a problem somewhere in the following. D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving. D "AUTO LSD" system D Traction control system D Vehicle stability control 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. It is not a malfunction that the warning light may stay on for 60 seconds after the ignition key is turned to "ON". NOTICE Do not drive with the "AUTO LSD" switch continuously turned on. 174 2005 4RUNNER from Sep. '04 Prod. (OM35843U)
