There is no maintenance to perform on the SRS yourself. The only periodi\
c maintenance recommended
on the SRS is that the air bag module and the sensor unit should be repl\
aced every ten years and that the
other components in the system (wiring, connectors, etc.) should also \
be inspected at this time. This
service must be performed by an authorized Volvo dealer.
