General
The purpose of the Supplementary Restraint System (SRS) is to reduce the impact of the driver and passenger

Driver airbag module.
l
Driver 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.
