01_SEQUOIA_U (L/O 0009) If the slip indicator light does not come on when the ignition is turned on, contact your Toyota dealer. When the active traction control is applied, the slip indicator light blinks. You may hear a sound in the engine compartment for a few seconds when the engine is started or just after the vehicle is started. This means that the active traction control system is in the self − check mode, and does not indicate malfunction. When the traction control system is operating, you may feel vibration or noise of your vehicle, caused by operation of the brakes. This indicates the system is functioning properly. When getting the vehicle out of mud or new snow, etc. the active traction control system will help operate to prevent the wheels from spinning. Active traction control system failure warning These lights warn that when there is a problem somewhere in the active traction control system. If the "VSC/TRAC" warning light and "VSC OFF" indicator light come on, have your vehicle checked by Toyota dealer as soon as possible. The lights will come on when the ignition key is turned on, and will go off after a few seconds. The brake actuator temperature increases during continuous operation of the active traction control system or vehicle skid control system such as on slippery roads. If the brake actuator temperature becomes too high while the active traction control system or vehicle skid control system is operating, a buzzer will start to sound intermittently to indicate that the active 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 "VSC/TRAC" warning light will come on and the active traction control system temporarily stops operating in order to protect the brake actuator. (Although the active traction control system does not operate, there is no problem to continue your driving.) The system will be automatically restored after a short time and the "VSC/TRAC" warning light goes out. When the "VSC/TRAC" warning light and "VSC OFF" indicator light come on the active traction control system does not operate, but there is no problem to continue your driving. 2001 SEQUOIA (OM34414U) 143
