Adjusting the front power seat (if equipped)
WARNING:Never adjust the driver’s seat or seatback when the
vehicle is moving.
WARNING:Do not pile cargo higher than the seatbacks to avoid
injuring people in a collision or sudden stop.
WARNING:Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING:Reclining the seatback can cause an occupant to
slide under the seat’s safety belt, resulting in severe personal
injuries in the event of a collision.
WARNING:Sitting improperly out of position or with the seat
back reclined too far can take off weight from the seat cushion
and affect the decision of the passenger sensing system, resulting in
serious injury or death in a crash. Always sit upright against your
seatback, with your feet on the floor.
WARNING:To reduce the risk of possible serious injury: Do not
hang objects off seat back or stow objects in the seatback map
pocket (if equipped) when a child is in the front passenger seat. Do
not place objects underneath the front passenger seat or between the
seat and the center console (if equipped). Check the “passenger airbag
off” or “pass airbag off” indicator lamp for proper airbag status. Refer
toFront passenger sensing systemin theAirbag supplemental
restraint system (SRS)section for additional details. Failure to follow
these instructions may interfere with the front passenger seat sensing

How does the Personal Safety System™ work?
The Personal Safety System can adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the Restraints control module (RCM). During a crash, the
RCM may activate the safety belt pretensioners and/or either one or both
stages of the dual-stage airbag supplemental restraints based on crash
severity and occupant conditions.
The fact that the pretensioners or airbags did not activate for both front
seat occupants in a collision does not mean that something is wrong with
the system. Rather, it means the Personal Safety System determined the
accident conditions (crash severity, belt usage, etc.) were not
appropriate to activate these safety devices. Front airbags are designed
to activate only in frontal and near-frontal collisions (not rollovers, side
impacts or rear impacts) unless the collision causes sufficient
longitudinal deceleration. The pretensioners are designed to activate in
frontal, and in side collisions and rollovers.
Driver and passenger dual-stage airbag supplemental restraints
The dual-stage airbags offer the capability to tailor the level of airbag
inflation energy. A lower, less forceful energy level is provided for more
common, moderate-severity impacts. A higher energy level is used for
the most severe impacts. Refer toAirbag supplemental restraints
section in this chapter.
Front crash severity sensor
The front crash severity sensor enhances the ability to detect the
severity of an impact. Positioned up front, it provides valuable
information early in the crash event on the severity of the impact. This
allows your Personal Safety System to distinguish between different
levels of crash severity and modify the deployment strategy of the
dual-stage airbags and safety belt pretensioners.

Driver’s seat position sensor
The driver’s seat position sensor allows your Personal Safety System to
tailor the deployment level of the driver dual-stage airbag based on seat
position. The system is designed to help protect smaller drivers sitting
close to the driver airbag by providing a lower airbag output level.
Front passenger sensing system
For airbags to do their job they must inflate with great force, and this
force can pose a potentially deadly risk to occupants that are very close
to the airbag when it begins to inflate. For some occupants, like infants
in rear-facing child seats, this occurs because they are initially sitting
very close to the airbag. For other occupants, this occurs when the
occupant is not properly restrained by safety belts or child safety seats
and they move forward during pre-crash braking. The most effective way
to reduce the risk of unnecessary injuries is to make sure all occupants
are properly restrained. Accident statistics suggest that children are
much safer when properly restrained in the rear seating positions than in
the front.
WARNING:Air bags can kill or injure a child in a child seat.
NEVERplace a rear-facing child seat in front of an active air
bag. If you must use a forward-facing child seat in the front seat, move
the seat all the way back.
WARNING:When possible, all children 12 years old and under
should be properly restrained in a rear seating position.
The front passenger sensing system can automatically turn off the
passenger front airbag. The system is designed to help protect small
(child size) occupants from airbag deployments when they are
improperly seated or restrained in the front passenger seat contrary to
proper child-seating or restraint usage recommendations. Even with this
technology, parents areSTRONGLYencouraged to always properly
restrain children in the rear seat. The sensor also turns off the passenger
front airbag and passenger seat-mounted side airbag when the passenger
seat is empty.
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. SeeFront passenger sensing systemin 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 to tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety restraintssection 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. 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 toEnergy
management featurein 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 theWarning lights and chimessection in theInstrument 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.
