'01 4Runner_U (L/O 0008) Active traction control system (four−wheel drive models) If the slip indicator light is left on after the ignition is turn on, have your vehicle checked by your Toyota dealer as soon as possible. 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. The active traction control system automatically helps control the spinning of 4 wheels (four−wheel drive mode) or rear wheels (two−wheel drive mode) which may occur when accelerating on slippery road surfaces, by controlling the output of the brake and engine. Thus, the system assists driver to control the driving power of 4 wheels (four−wheel drive mode) or rear wheels (two−wheel drive mode). When you turn the ignition switch on, the active traction control system always turns on automatically, and the slip indicator light will come on. The indicator lights will go off after about a few seconds.
