All models are equipped by auxiliary system of safety (SRS — Supplemental Restrain System) more known, as safety pillows. The system consists of the gauges of blow established from the forward party of the car, pillows of safety and the block of management and diagnostics, located about the central console.
During collision pyrotechnic газогенератор inflates a safety pillow emergency explosive process, providing full filling before contact to the driver or the forward passenger. Then the safety pillow reacts to contact to the driver or the forward passenger partial reduction of pressure of the operation calculated according to physiologically comprehensible pressure and braking forces, operating on the driver or the forward passenger. It is as a result warned or considerably the probability and weight of wounds of a head and a thorax decreases.
The pillow of safety of the driver is established in the steering wheel centre. For a signal transmission from the management block to a safety pillow the spiral wire established on a steering column is used. The spiral wire transmits a signal irrespective of steering wheel position. Pyrotechnic газогенератор will transform an operating electric signal to an arson signal therefore the powder decays, inflating a bag of a pillow of safety.

The pillow of safety of the forward passenger is established over a ware box and closed by a decorative cover (fig. 15.64
). Volume of a pillow of safety it is considerable больший
, than volume of a pillow of safety of the driver. The decorative cover is painted in colour of the panel of devices and has a seam which is broken off at operation of a pillow of safety.
The block of indication and diagnostics submits operating pressure to safety pillows at collision even if the storage battery is disconnected as a result of blow. Diagnostics block supervises system of safety each time at engine start-up, thus in a combination of devices the signalling device which in some seconds dies away if the system is serviceable is lighted. If in system there are malfunctions, the signalling device will blink and the sound signal will be distributed. In this case it is necessary to address as soon as possible on servicing deport.
Before work about gauges of blow, the panel of devices and a steering column establish forward wheels for movement directly forward, switch off ignition, disconnect at first negative, and then positive the plug from the storage battery and wait 2 minutes It will exclude unapproved disclosing of pillows of safety and operation натяжителей seat belts which can put physical injuries.
