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 Safety System to tailor the airbag deployment and seat belt
pretensioner activation depending upon seat belt usage. Refer to
Seat
belt
section in this chapter.
Front 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, and in side collisions and rollovers when the
vehicle is equipped with the Safety Canopy
威
system. 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.
Seat belt energy management retractors
The front and rear outboard seat belt energy management retractors,
once initiated, 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
姞
is operational
The 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 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, 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 Safety
System serviced at an authorized dealer immediately. Unless serviced,
the system may not function properly in the event of a collision.
