How does the Safety System work?

The Safety System can adapt the deployment strategy of your vehicle’s
safety devices according to crash severity and occupant conditions. A
collection of crash and occupant sensors provides information to the
Restraints control module (RCM). During a crash, the RCM activates the
safety belt pretensioners, equipped with a pyrotechnic dual retractor
(driver’s side only) and/or either the single stage passenger airbag or
both stages of the dual-stage driver airbag supplemental restraints based
on crash severity and occupant conditions.

The fact that the pyrotechnic dual retractor (driver’s side only),
pretensioners or airbags did not activate for both front seat occupants in
a collision does not mean that something is wrong with the system.
Rather, it means the Safety System determined the accident conditions
(crash severity, belt usage, etc.) were not appropriate to activate these
safety devices. Front airbags, pretensioners, equipped with a pyrotechnic
dual retractor (driver’s side only) are designed to activate only in frontal
and near-frontal collisions, not rollovers, side-impacts, or rear-impacts
unless the collision causes sufficient longitudinal deceleration.

Driver dual-stage airbag supplemental restraints (driver seating
position only)

The dual-stage airbag offers the capability to tailor the level of airbag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer to Airbag supplemental restraints
section in this chapter.

Front crash severity sensor

The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Safety System to distinguish between different levels of crash
severity and modify the deployment strategy of the driver dual-stage
airbag and safety belt pretensioners equipped with pyrotechnic dual
retractor (driver’s side only).
