|
|
Latest models are equipped with auxiliary system of the safety (SRS) including a pneumosafety cushion. This system is developed to protect the driver from serious traumas in case of a head-on collision. The system consists of the pneumopillow module in the center of the steering wheel, two sensors of blow mounted on panels of forward wings from the inside, and the sensor of safety which is in a passenger compartment. Sensors of blow of SRS system (it is specified by an arrow) are located in an impellent compartment - regularly check, whether there are no conducting damages. |
The module of a pneumosafety cushion includes a casing for a pillow and pump blocks for pillow inflating. Assembly of the pump is mounted in a back part of a casing over an opening through which gas arrives, inflating a pillow almost instantly after the system sends an electric signal. This signal is transferred on a wire which is specially braided several times that the signal was transferred irrespective of the provision of a steering wheel.
The SRS system has three sensors: two in front, established on panels of wings from the inside, and the sensor of safety located in a passenger compartment. Blow sensors usually react to pressure, closing an electric chain during blow of sufficient force. The electric signal from sensors of blow is sent to the third sensor which then closes a chain and inflates a pneumopillow.
The module containing the sensor of safety, watches system work. It checks system work each time at ignition inclusion, forcing to be lit by an alarm lamp AIRBAG (pneumopillow), and then being switched off, if the system works normally. If the system is faulty, the alarm lamp remains included. If the lamp of AIRBAG remains included or if it is lit in car operating time, immediately send your car in dealer office of service.
