AdvanceTrac with RSCTM (Roll Stability Control) works in conjunction with the Anti-lock Brake System (ABS), traction control and yaw control. The system automatically determines when and how to apply individual brakes and modify engine power to help keep all 4 wheels firmly planted. It’s the only stability control system with gyroscopic sensors measuring both vehicle roll and turning rates. When turning or swerving too quickly, the RSCTM applies brake pressure and reduces engine power to help keep you under control.
