Seating and Safety Restraints
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 air
bags and safety belt pretensioners.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer to Safety Belt section in this chapter.
Front safety belt pretensioners
The front outboard safety belt pretensioners are designed to tighten the
safety belts firmly against the occupant's body during a collision. This
maximizes the effectiveness of the safety belts and helps properly
position the occupant relative to the air bag to improve protection. The
safety belt pretensioners can be either activated alone or, if the collision
is of sufficient severity, together with the air bags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant's forward momentum. This helps
reduce the risk of force-related injuries to the occupant's chest by
limiting the load on the occupant. Refer to Safety Belt section in this
chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning Light section in the Instrument Cluster chapter.
Routine maintenance of the Personal Safety System is not required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, and front safety belt buckle sensors. In
addition, the RCM also monitors the restraints warning light in the
instrument cluster. A difficulty with the system is indicated by one or
more of the following:
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after the ignition is
turned on.
