'01 4Runner_U (L/O 0008) Leave the system on during ordinary driving so that it can operate when needed. When 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 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 traction control system will help operate to prevent the wheels from spinning. If your wheels get stuck in a ditch or when you are driving on a slippery or bumpy surface, turn off the traction control system because its function that controls engine performance interferes with the process of freeing your wheels. You can turn off the traction control system by pushing the "TRAC OFF" switch. The "TRAC OFF" indicator light will come on. Pushing the "TRAC OFF" switch a second time turns on the traction control system again and the "TRAC OFF" indicator light will go off. The traction control system will automatically go on, and the "TRAC OFF" indicator light will go off when you drive over 30 km/h (19 mph) even if the "TRAC OFF" switch is pushed to cancel the traction control system. 118 2001 4RUNNER (OM35768U)
