Seating and Safety Restraints

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 restraints section in this chapter.

Front 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 and rollovers when the
vehicle is equipped with the Safety Canopy
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 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 restraints 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 air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, 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 the 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.
