07 04.26 The brake actuator temperature increases during continuous operation of the following systems under conditions such as on slippery roads. To turn on: Briefly push the "VSC OFF" switch once again. The "AUTO LSD" and slip indicator lights will go off. D Traction control system D "AUTO LSD" system 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. XS17010a If the engine is turned off while the "AUTO LSD" and slip indicator lights are on and then restarted, the indicator lights will turn off automatically. 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 248 in this Section. "AUTO LSD" and slip indicator lights come on for a few seconds when the ignition switch is turned to the "ON" position. If the indicator lights do not come on when the ignition switch is turned to the "ON" position, contact your Toyota dealer. TRACTION CONTROL OFF MODE (two−wheel drive mode only) When getting the vehicle out of mud or newly fallen snow, etc., it may be beneficial to turn off the traction control system. This system that controls engine performance interferes with the process of freeing rear wheels. To turn off: Briefly push the "VSC OFF" switch. The "AUTO LSD" and slip indicator lights will come on. The vehicle stability control system is always activated, even if the traction control system is turned off. CAUTION Do not drive with the traction control system continuously turned off. 2007 TUNDRA from Jul. '07 Prod. (OM34463U) 243
