Mercedes S-Class W-220

1. Periodically check liquid level in system of hydrostrengthening of a wheel in order to avoid emergence of problems with management of the car, such as damage of the steering pump. Act as follows.

Do not hold a steering wheel turned against the stop in this or that party more than five seconds. It can put the steering pump out of action.

2. The tank of system of hydrostrengthening of a wheel is located in a motive compartment and has the unscrewing cover with the measuring probe which is built in in it.

3. Park the car on the flat platform and cock the parking brake.
Level of oil can be checked in a cold or heated-up state (since +50 °C). Here check in a cold state is described. Pay attention to the remarks provided in the end of the Section if the level of oil has to be checked in a heated-up state.
4. The car should not be heated-up, the engine should not work. Forward wheels have to stand directly.
5. Turn off a tank stopper by means of the screw-driver. For this purpose insert a screw-driver core into a stopper groove.
6. Wipe with a pure rag the index of level under a cover.
7. Manually screw and again turn off a stopper. Liquid level in the compensation tank depending on its temperature has to coincide with the corresponding zone of the index.
8 Liquid cold (at ambient temperature): level has to be in area - And - (cool).
Liquid at a working temperature (about +50 °C): level has to be in the hot area.
9. If necessary liquid level in the tank should be added. For addition of level use only new liquid as even the most insignificant impurity can lead to violation of work of hydraulic system.

Attention! If liquid level in the tank fell below a zone, the corresponding temperature of liquid, steering with the hydraulic amplifier of the steering mechanism needs to be checked in a specialized workshop as liquid loss takes place. In this case it is not enough to be limited only to addition of level of liquid.
