Front seat belt usage sensors
The front seat belt usage sensors detect whether or not the driver and
front outboard passenger seat belts are fastened. This information allows
your Personal Safety System™ to tailor the airbag deployment and seat
belt pretensioner activation depending upon seat belt usage. Refer to
Seat belt usage sensors
later in this chapter.
Front outboard seat belt pretensioners
The seat belt pretensioners at the front outboard seating positions are
designed to tighten the seat belts firmly against the occupant’s body
during frontal collisions. This helps increase the effectiveness of the seat
belts. In frontal collisions, the seat belt pretensioners can be activated
alone or, if the collision is of sufficient severity, together with the front
airbags.
Front outboard seat belt energy management retractors
The front seat 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
Energy management retractors
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 lights and chimes
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 airbag supplemental restraints, crash sensor(s),
seat belt pretensioners, front seat belt buckle sensors, front passenger
sensing system, and the driver seat position sensor. 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 ignition is
turned on.
•
A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
