STARTING AND DRIVING This light warns that there is a problem somewhere in the traction control system or the vehicle stability 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. In the following cases, contact your Lexus dealer: D The warning light does not come on after the ignition key is turned to "ON". D The warning light remains on after the ignition key is turned to "ON". D The warning light comes on while driving. The "TRAC OFF" indicator light will come on when the "VSC" warning light comes on even if the "TRAC OFF" switch is not pushed. VEHICLE STABILITY CONTROL SYSTEM The vehicle stability control system helps provide integrated control of the systems such as anti−lock brake system, traction control, engine control, etc. This system automatically controls the brakes and engine to help prevent the vehicle from skidding when cornering on a slippery road surface or operating steering wheel abruptly. This system will activate when your vehicle speed reaches or exceeds 15 km/h (9 mph), and will deactivate when the vehicle speed reduces to below 15 km/h (9 mph). You may hear a sound in the engine compartment for a few seconds when the engine is started or just after the vehicle begins to move. This means that the system is in the self−check mode but does not indicate a malfunction. CAUTION D Do not rely excessively on the vehicle stability control system. Even if the vehicle skid control system is operating, you must always drive carefully and attentively to avoid serious injury. Reckless driving will result in an unexpected accident. If the slip indicator light blinks, sounding an alarm, special care should be taken while driving. 272
