'01 HIGHLANDER_U (L/O 0106) While the "VSC" warning light and "TRAC OFF" indicator/warning light come on, the traction control system cannot be operated. 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. You can turn off the traction control system by pushing the "TRAC OFF" switch. The "TRAC OFF" indicator/warning light will come on. Pushing the "TRAC OFF" switch a second time turns on the traction control system again and the "TRAC OFF" indicator/ warning light will go off. At this time, the vehicle skid control also turns off and on simultaneously. TRACTION CONTROL SYSTEM FAILURE WARNING These lights warn that there is a problem somewhere in the vehicle skid control system or traction control system. The lights will come on when the ignition key is turned to "ON", and will go off after about a few seconds. If the "VSC" warning light and "TRAC OFF" indicator/warning light come on, the vehicle skid control system and traction control system do not work. However, as conventional braking operates when applied, there is no problem to continue your driving. 116 2001 MY HIGHLANDER_U (OM48432U)
