  "textContent": "A vehicle height adjustment system operable to start vehicle height adjustment control even when an air suspension air tank (4) is empty or sufficient air is not left therein includes a compressor (21) which produces compressed air, a control valve (8) which controls air supply and discharge to/from air springs (15,16,17,18), a control unit (30) which controls a valve opening/closing operation of the control valve (8), an air passage (51) which connects between the compressor (21) and the control valve (8) through a main air tank (1) bypassing the air suspension air tank (4), and pressure detection means (12) which detects an internal pressure value of the air passage (51). The control unit (30) controls start and stop of air supply, namely, start and stop of vehicle height adjustment control at the magnetic valve (8), based on the internal pressure value detected by the pressure detection means (12).",
