WARNING: All pyrotechnic devices are dangerous. Before attempting to operate a pyrotechnic device, read the Standard Repair Procedures section of this manual. For additional information, refer to the chapter: Standard Service Station Procedures (100-00 General Information, Description and Operation). (100-00, Description and Operation).

Continuous improvement of the Supplemental Restraint System (SRS) improves the overall level of occupant protection in a collision. The system analyzes the passenger compartment load pattern and the force of the impact, and then activates the appropriate passive safety devices to improve occupant protection in a variety of accident situations. The system's benefits include:

• Optimizing the performance of passive safety devices and reducing the risk of injuries caused by airbags.
• Significant reduction in the number of passenger airbag deployments, especially when only the driver is in the vehicle.

The car is equipped with seven airbags, each of which performs a specific protective 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 restrain them in the event of a rollover.
• The driver's lower airbag protects the driver's legs from injury from the steering column structures.

To meet SRS requirements, the passive restraint system control architecture includes the following components:

• Electronic frontal and side impact sensors, modern control system for protective devices.
• Driver's airbag with two-stage gas generator.
• Passenger airbag with two-stage gas generator.
• Depending on the market, the front passenger seat:
  • occupant 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 energy absorption level.
