WARNING: All pyrotechnic devices are dangerous. Before performing any action on a pyrotechnic device, read the section "Standard repair operations" this guide. For more information, see the chapter: Standard Techniques Used in a Service Station (100-00 General information, Description and principle of operation). (100-00, «Description and operation»).

Continuous improvement of the additional protection system for the driver and passengers (SRS) provides an increase in the overall level of protection for the driver and passengers in a collision. The system analyzes the passenger compartment load pattern and impact force, and then activates the appropriate passive safety devices to increase the protection of the driver and passengers in a variety of emergency situations. The advantages of the system include:

• Optimizing the performance of passive safety devices and reducing the risk of injury caused by airbags.
• A significant reduction in the number of passenger airbag deployments, especially if only the driver is in the passenger compartment.

The car is equipped with seven airbags, each of which performs a specific protection function:

• Driver and passenger airbags protect the head and chest of front seat occupants.
• Driver and passenger side airbags provide side impact protection.
• Side curtain airbags protect the heads of the driver, front and rear passengers, and also hold them when they roll over.
• The lower driver's airbag protects the driver's legs from injury from steering column structures.

To comply with SRS requirements, the passive safety system management architecture includes the following components:

• Electronic frontal and side impact sensors, a modern control system for protective devices.
• Driver's airbag with two-stage gas generator.
• Passenger airbag with two-stage gas generator.
• Depending on market, front passenger seat:
  • passenger classification system sensors, or
  • passenger presence sensors
• Seat belt pretensioners.
• Driver's seat position sensor.
• Depending on the market, a pyrotechnic actuator on the steering column to increase the level of energy absorption.
