Aston Martin DB11 Owner's Handbook Manual page 57

All of these systems are controlled by the Occupant Restraint
Controller (ORC). In a collision the ORC will analyse information
from various sensors, such as crash and seat occupancy
conditions. Based on this information the system will deploy the
appropriate safety devices. During a crash, the ORC may or may
not operate the safety belt pre-tensioner(s) and none, one, or
both stages of the dual-stage airbag supplemental restraints.
If the pre-tensioners or airbags do not operate in a collision it
does not mean that something is wrong with the system. Rather,
it means the system determined the accident conditions (crash
severity, belt usage, etc.) were not appropriate to operate these
safety devices.
Front airbags are designed to operate only in frontal and near-
frontal collisions, not rollovers, side-impacts, or rear-impacts
unless the collision causes sufficient longitudinal deceleration.
Determining if the System is Operational
The ORC warning symbol is shown in the instrument cluster
to give the condition of the system. A fault with the system is
shown by one or more of the following:
• The warning symbol will flash or stay ON.
• The warning symbol does not come ON immediately after the
ignition is set to ON.
• A message will show in the right side instrument cluster
window with a description of the fault.
If either of these conditions occur, even intermittently, have the
restraint system serviced at your Aston Martin Dealer
immediately. Unless serviced, the system may not operate
correctly in the event of a collision.
