Safety cushions – the general information

General information

Some of the models considered in the present manual are equipped with system of additional safety (SRS) better known under the name of safety cushions. The system provides additional protection of the driver and forward passenger of the car at strong front blow. The module of a driver's pillow is placed under an overlay of a steering wheel. The module of a passenger safety cushion is located on the right under the car dashboard on which surface at the same time the warning inscription in the form of SRS abbreviation is applied.

The block of sensors / the diagnostic module is located also under the dashboard, in its central part (address an accompanying illustration).

Modules of safety cushions

Activation of a pillow(s) of safety happens on condition of operation of sensors of the directed SRS overloads. Short circuit of a chain of the module of a safety cushion leads to almost instant filling of the last with the nitrogen which is emitted as a result of combustion of powdery mix of azid of sodium with copper oxide. In case of failure of the onboard rechargeable battery the system switches to food from the reserve source which is built in in the SRS module. It is necessary to notice that the passenger safety cushion usually is more on volume, than driver's and it is equipped with the metal bearing case, at operation of the module which is divided into two half and a finishing cover.

Block of sensors / diagnostic module

The module of sensors and self-diagnostics of SRS provides giving of power supply to modules of safety cushions at the time of the collision causing rather strong directed overloads. Operation of system happens even in case of crash of the onboard rechargeable battery. A survey of a condition of the SRS components is carried out by the module at each start of the engine and is followed by short-term operation of the control lamp "AIR BAG" which is built in in the dashboard of the car. In case of what exit - beat out of operation shutdown of a control lamp does not come from knots. Also operation of a control lamp testifies to malfunction in system during the movement, the car should be driven away as soon as possible on car repair shop.
