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 airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Front outboard safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions when the side air curtain
system activates. This helps increase the effectiveness of the safety belts.
In frontal collisions, the safety belt pretensioners can be activated alone
or, if the collision is of sufficient severity, together with the front airbags.
Front outboard safety belt energy management retractors
The front 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.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster, a warning message, or a backup tone to indicate the condition of
the system. Refer to the Warning lights and indicators 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),
safety belt pretensioners, front safety 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 warning message will appear until the problem and warning light are
repaired.
If any of these things happen, even intermittently, have the Personal Safety
System serviced at an authorized dealer immediately. Unless serviced, the
system may not function properly in the event of a collision.
