Seating and Safety Restraints
Driver and passenger dual-stage
air bag supplemental restraints
The dual stage air bags offer the
capability to tailor the level of air
bag 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 Air bag supplemental
restraints system (SRS) 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 Personal Safety System
to distinguish between different
levels of crash severity and modify
the deployment strategy of the
dual stage air bags and safety belt
pretensioners.
Driver's seat position sensor
The driver's seat position sensor
allows your Personal Safety System
to tailor the deployment level of the
driver dual stage air bag based on
seat position, modifing the level of
restraint as appropriate for smaller
drivers.
