A vehicle suspension apparatus has suspension units each with a height control fluid spring chamber, fluid supply valves for supplying a fluid from a fluid source to the spring chambers through corresponding supply control valve means, and fluid exhaust valve means for exhausting the fluid from the fluid spring chambers through exhaust control valve means. The supply control valve means are opened only for a predetermined period of time to increase the height by a predetermined distance upon the operation of a high height selection switch, thereby increasing the height to the maximum height.
