On a closed course with professional drivers, Lexus engineers demonstrate the effect of the 2010 GX 460's Vehicle Stability Control (VSC) system update. Vehicle Stability Control (VSC) is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether VSC will be effective in preventing a loss of control. Please see your Owner's Manual for further details and do not attempt this demonstration.
