The front passenger sensing system can automatically turn off the
passenger front airbag when a rear facing child seat, a forward-facing
child restraint, or a booster seat is detected. Even with this technology,
parents are
STRONGLY
encouraged to always properly 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
Airbag
supplemental restraint system (SRS)
section of this chapter.
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 Personal Safety System
威
to tailor the airbag deployment and seat
belt pretensioner activation depending upon seat belt usage.
Front outboard 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. 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.
Front outboard seat belt energy management retractors
The front seat 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
姞
is operational
The Personal Safety System
威
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
威
is not
required.
