Before Driving
Occupant Classification System
The Occupant Classification System (OCS) is part of Occupant
restraints Control (ORC) System and operates in addition to the
restraints system. OCS is designed to meet the regulatory
requirements of Federal Motor Vehicle Safety Standard (FMVSS)
208 to set the front passenger airbag to OFF under certain
conditions.
OCS uses capacitive measurement to differentiate between
adults, occupied small (1 year old or younger) child restraint
seats, and empty seats. Capacitive measurement is not weight
sensitive and depends on chemical and physical features to
determine if an object or a person is in the passenger seat. This
information is then sent to the ORC module.
If OCS determines an adult is in the passenger seat, the passenger
airbag will be active.
If OCS determines there is a child restraint seats (CRS) present, or
the seat is empty, the passenger airbag will be automatically
switched off.
If it is necessary to modify the advanced restraints system to
accommodate a person with disabilities, contact your Aston
Martin Dealer .
