restrain children in the rear seat. The sensor also turns off the airbag
when the passenger seat is empty to prevent unnecessary replacement of
the airbag(s) after a collision.
When the front passenger seat is occupied and the sensing system has
turned off the passenger’s frontal airbag, the “pass airbag off” indicator
will light and stay lit to remind you that the front passenger frontal
airbag is off. See
Front passenger sensing system
in the airbags section
of this chapter.
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
娂
to tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer to
Safety Belt
section in this chapter.
Front outboard safety belt pretensioners
The safety belt pretensioners are designed to tighten the safety belts
firmly against the occupant’s body during a collision. This maximizes the
effectiveness of the safety belts and helps properly position the occupant
relative to the airbag to improve protection. The safety belt
pretensioners can be either activated alone or, if the collision is of
sufficient severity, together with the 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. Refer to
Safety Belt
section in this chapter.
Determining if the Personal Safety System
姟
is operational
The Personal Safety System
娂
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
娂
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, 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.
