Abstract

A method of adjusting an air suspension system comprises detecting with a positioning system that the vehicle is approaching a park location and reporting the park location is approaching to an electronic control unit for the air suspension system. A vehicle speed is determined and compared to a predetermined speed threshold, with the electronic control unit. The electronic control unit selects a park mode for the suspensions system when the vehicle is approaching the park location and when the vehicle speed is below the predetermined threshold. Air supply for the air suspension system is controlled to adjust the corner assemblies for the air suspension system to lowered positions associated with the park mode.
