In response to the driving environment, AHC automatically adjusts the optimal vehicle height based on drive mode select, Multi terrain Select, and transfer selection status to one of four height positions-Normal, High 1, High 2, and Low, for getting into or out of the vehicle. AHC also responds to changes in vehicle posture such as the amount of pitch and roll, and optimizes the spring rate to stabilize vehicle posture during turning, acceleration, and deceleration when braking.
