07 12.25 When you push and hold the "VSC OFF" switch for 3 seconds or more with the vehicle stopped, turn off the vehicle stability control system. See "Vehicle stability control system" on page 183 in this Section. CY16076 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. 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 engine switch is turned to "ON". If the indicator lights does not come on when the engine switch is turned to "ON", contact your Toyota dealer. 181
