The purpose of the Supplementary Restraint System (SRS) is to reduce the impact of the driver and passenger against the vehicle's interior in the event of a serious accident.

The SRS system is a stand-alone system. There are no remotely mounted crash sensors. The only external input to the DCU is power. The system only becomes live when the ignition is switched on.

The SRS consists of the following components:
^ Diagnostic and control unit (DCU).
^ SRS warning lamp. Rotary coupler.
^ Driver airbag module.
^ Driver seat belt pretensioner.
^ Passenger airbag module.
^ Passenger seat belt pretensioner.

The passenger airbag is optional in some markets. All other components are standard fit in all markets. The SRS functions the same in all markets.
