The suspension system also incorporates a new damping system know as Road Sensing Suspension. This system control the damping forces in the shock absorbers and struts, in response to various road and driving conditions. The systems are capable of making these damping changes extremely fast. A computer receives inputs from vertical acceleration sensors, wheelbody to position sensors, vehicle speed sensor, lift and dive signals. This computer evaluates the inputs from these sensors, control the damping of each of the to of struts and shocks independently to provide varied levels suspension control. The system also has the capability of providing Speed Sensitive Steering control. This system changes your steering effort on your vehicle speed. based Speed Sensitive Steering This system varies amount of steering effort the proportionate to your vehicle speed. Steeringis easier at a lower speed increased maneuverability and for parking ease. As your vehicle speed increases, the steering effort is also increased to provide a manual like steering feel for maximum control and enhanced vehicle stability. The power rack and pinion steering system has a rotary spool valve whi directs hydraulic fluid coming from power steering pump one side or the to attached to the the other side of the rack piston.The integral rack piston is 323
