'03 HIGHLANDER_U (L/O 0208) When the traction control system is operating, the following conditions occur: D The system controls the spinning of the 4 wheels. At this time, the slip indicator light blinks. D You may feel vibration or noise in your vehicle, caused by operation of the brakes. This indicates the system is functioning properly. The slip indicator light comes on for a few seconds when the ignition key is turned to "ON". If the indicator light does not come on when the ignition is turned on, contact your Toyota dealer. NORMAL DRIVING MODE Leave the system on during the ordinary driving so that it can operate when needed. 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, but does not indicate a malfunction. "VSC" warning light This light warns that there is a problem somewhere in the traction control system or the vehicle skid control system. The light will come on when the ignition key is turned to "ON" and will go off after a few seconds. If the light comes on while driving, the system does not work. However, as conventional braking operates when applied, there is no problem to continue your driving. 122 2003 HIGHLANDER from Aug. '02 Prod. (OM48441U)
