DESCRIPTION AND OPERATION 75-3
Description - SRS
General
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:
lDiagnostic and control unit (DCU).
lSRS warning lamp.
lRotary coupler.
lDriver airbag module.
lDriver seat belt pretensioner.
lPassenger airbag module.
lPassenger 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.
