In a vehicle-height control system, an actuator-side passage is connected to a fluid supply and discharge device. A vehicle-height control actuator is connected to the actuator-side passage via a vehicle-height control valve. At a start of vehicle height control, the vehicle-height control valve is switched from a closed state to an open state after the actuator-side passage is fluidically coupled with the air supply and discharge device. For example, at a start of up control, a tank of the fluid supply and discharge device is fluidically coupled with the actuator-side passage to increase a pressure of fluid in the actuator-side passage. This operation makes it difficult for fluid to be discharged from the vehicle-height control actuator to the actuator-side passage when the vehicle-height control valve is thereafter switched from the closed state to the open state. Accordingly, unintentional lowering of vehicle height can be prevented.
