Steering with the hydraulic booster (servoupravleniye)Elements of a steering column and steering wheel
Rotation of a steering wheel is transmitted by the driver through a steering column and the steering mechanism, and also steering drafts on car wheels. The steering column can be regulated manually on height and in the longitudinal direction.
The effort necessary for turn of wheels, especially on the standing car, decreases thanks to existence of the hydraulic booster. The power steering consists of the oil pump, the tank of oil and oil pipelines. The oil pump is set in motion from the engine through maple a belt with edges. The pump we suck in oil from the tank and under a high pressure gives it to the valve case. The case of the valve is located in the steering mechanism. It has mechanical communication with a steering column and depending on the direction of a rearrangement of a wheel directs oil to the relevant party of the working cylinder. Here oil influences the piston with a gear lath, reducing, thus, effort which needs to be put for turn of a wheel.
In a steering wheel the safety cushion is located. The safety cushion represents the put bag which is inflated with air at frontal collision and thus protects a trunk and the driver's head from blow about a steering wheel. At frontal collision of a certain force in a safety cushion through a monitor the small charge ignites. As a result of explosion gases which during several milliseconds fill an air bag are formed. It is enough this time to damp the driver's trunk directing forward. Then the safety cushion within several seconds again develops as gases leave a pillow via outlets.
Security measures at the address with a safety cushion
Near a safety cushion of the driver in a steering wheel there is a safety cushion of the forward passenger located over a ware box, lateral safety cushions in the doorway and a safety cushion for the head over doors.

Besides, on a door rack, a solar peak or on the dashboard on the right side there has to be a plate "a children's seat ahead is not present". In the absence of the last the driver can be fined by police of Germany.
At removal and installation of the block of a safety cushion it is necessary to observe the following:
1 Disconnect a negative cable (-) of the battery at the switched-off ignition. The battery is in a luggage compartment behind a cover on the right side. At BMW 316i, 318i cars the battery settles down in a motive compartment.
2 Isolate a negative pole (-) of the battery to exclude casual contact.
3 Before installation of a safety cushion again check, whether the negative cable of the battery is disconnected.
General measures of safety

- The safety cushion is allowed to be checked only for HUNDRED. By no means it is impossible to apply a control lamp, the voltmeter or an ohmmeter to check of a pillow.
- When carrying out welding works the plug of the welding machine has to settle down in close proximity to a welding place. It is necessary a negative cable of the battery and to isolate a battery pole to exclude possibility of casual contact. It is necessary to rasstykovat shtekerny connections of a safety cushion to gas generators.
- It is not necessary to subject even to short-term influence of temperature above +75 °C the block of a pillow and a monitor.
- Observe instructions concerning a natyazhitel of a seat belt, address to the Section Natyazhitel of a seat belt. Main data and security measures.
