STARTING AND DRIVING VEHICLE DYNAMICS INTEGRATED MANAGEMENT (GS430 only) Vehicle Dynamics Integrated Management (VDIM) helps manage control for vehicle stability control system, anti−lock brake system, brake assist system, traction control system, engine output control, hill−start assist control system and also manages variable gear ratio steering system and electric power steering system. In order to control sudden steering wheel operation and the sideslip on slippery road surfaces, this system provides excellent vehicle stability by automatically controlling the brake, engine output and front wheel angle. The state of the tires will affect the performance of the vehicle dynamics integrated management system. Be sure to check the following: D Are tires of specified size installed? D Are tires of identical type installed? D Do the tires have stipulated tire pressure? D Are the tires worn? A problem with the tires or modified suspension systems will have an adverse effect on the system and may cause a malfunction, so be careful. When the slip indicator light comes on, and the message "CHECK ECB" appears on the multi−information display, the vehicle dynamics integrated management does not operate. Have your vehicle checked by your Lexus dealer as soon as possible. In addition, when the master warning light comes on, and the message "CHECK VGRS" or "CHECK P/S" appears on the multi−information display, the system will not be temporarily functioning. Although it is no problem in driving as usual, have your vehicle checked by your Lexus dealer as soon as possible. CAUTION Do not overestimate the vehicle dynamics integrated management. Even when this management is functional, there is a limit to vehicle stability, and irresponsible driving may lead to an accident. When driving, you should always pay attention to your speed and keep a safe distance between your vehicle and the vehicle in front. 426
