The steering consists of a steering wheel, a steering shaft, the steering mechanism, steering draught, the steering shock-absorber and the wheel hydraulic booster. The steering wheel is screwed on a steering shaft which transfers wheel rotation to the steering mechanism.

Depending on wheel position transfer to the steering mechanism changes. It means that than turn of a wheel more, especially indirect there is a transfer. The steering wheel thus, for example, at a parking, turns easier. Direct transfer on the average position provides the raised accuracy of management, in particular on high speeds.

The hydraulic booster provides small effort to a steering wheel. It consists of the pump, the tank and tubes. The pump soaks up oil for hydraulics from the tank and submits it under pressure to the steering mechanism where the regulating device and the working cylinder provide corresponding strengthening.

As the additional equipment the mechanical regulator of length of a steering column for steering wheel installation can be put.

While the inflatable pillow of safety for the driver is built in a steering wheel, the pillow for the passenger is on the right on the forward panel. At strong front blow works пиропатрон, and pillows are inflated for thousand fractions of a second. It is enough this time to soften front blow for people. For few seconds after operation the pillow is blown off, as gases leave through apertures in it. The inflatable pillow for the passenger is put as the additional equipment.

The firm recommends to replace an inflatable pillow after ten years' operation of the car to guarantee its work.
