The steering has a hydraulic power. It helps to reduce the forces on the steering wheel when cornering. Power consists of an oil pump, a tank with hydraulic fluid and oil pipelines.
The oil pump is driven by a propeller shaft of the engine through a V-belt. The pump pumps the working fluid from the tank and delivers it under high pressure to the steering mechanism. The adjusting unit provides the necessary power steering assist. Depending on the model and configuration work is related to the power steering system speed (parameter control). On standing or slow-moving vehicle thanks to the electronic controller provides maximum support - effort on the steering wheel when turning small. With an increase in speed to 100 km / h respectively, support decreases over this limit, the steering acts just like a car without power steering. Reducing the power-steering function at higher speeds provides better contact with the road, and a high definition control. Electronic parametric control is in the control unit systems, traction control (ETS, ASR, ESO).
Rack and pinion steering gear must be free to move from one extreme to the other and have no backlash. The system requires no maintenance. Nevertheless, should regularly check the condition of protective sleeves and the fluid level in the power steering reservoir.
