STARTING AND DRIVING Traction control system failure warning VEHICLE STABILITY CONTROL SYSTEM The vehicle stability control system helps provide comprehensive 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 activates when the vehicle speed is about more than 15 km/h (9 mph). G31039 " 1 GS430 2 GS300 If the traction control system malfunctions, the slip indicator light (two−wheel drive models only) and brake system warning light (yellow) come on. At this time, the above message appears. (GS430 only-In some cases, the multi−information display shows either "CHECK VSC" or "CHECK ECB" only.) If the message appears, the traction control system, vehicle stability control system and hill−start assist control system do not work. Although it is no problem to continue driving, have your vehicle checked by your Lexus dealer as soon as possible. You may hear a sound in the engine compartment for a few seconds just after the vehicle begins to move. This means that the system is in the self−check mode, but does not indicate a malfunction. 420
