A vehicle includes a suspension corner connecting the vehicle's road wheel to the vehicle's body and characterized by a ride height at the suspension corner. An actuator at the suspension corner is configured to selectively extend and contract in response to a volume of received pressurized fluid to selectively increase and reduce the ride height. The actuator includes a locking device configured to selectively restrain the piston in a predetermined position and release the piston, and includes an actuation mechanism for activating the device to restrain the piston in the predetermined position. A controller is configured to determine if a change in the ride height is required and to assess if the piston is restrained by the locking device. If the piston is restrained by the locking device and the change in ride height is required, the controller releases the piston via the device and then changes the ride height.
