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. 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.

Safety belt energy management retractors

The front and rear 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 Energy
management feature 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 airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and front passenger sensing system. 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.
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.

Safety restraints precautions

WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
