SEATING
Adjusting the front manual seat (if equipped)WARNING: Never adjust the driver’s seat or seatback when the
vehicle is moving. The seat could slide too far leaving you
unable to operate vital controls just when you need them.
WARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips. Sitting in a
reclined position while the vehicle is moving is dangerous
because you cannot get the full protection from safety belts.
During sudden braking or a collision, you can slide under the
lap belt and suffer serious internal injuries. For maximum
protection, sit well back and upright. The lap portion of the
safety belt worn too high is dangerous. In a collision, this would
concentrate the impact force directly on the abdominal area,
causing serious injury. Wear the lap portion of the belt snugly
and as low as possible.
WARNING: The passenger 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 front passenger
sensing system, resulting in serious injury or death in a crash.
Always sit upright against your seatback, with your feet on the
floor.
Lift the release bar to move seat
forward or backward. Ensure that
the seat is locked into place.

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of
frontal crash protection to front seat occupants and is designed to help
further reduce the risk of airbag-related injuries. The system is able to
analyze different occupant classifications and conditions and crash
severity before activating the appropriate safety devices to help better
protect a range of occupants in a variety of frontal crash situations.
Your vehicle’s Personal Safety System consists of:
• Driver and passenger dual-stage airbag supplemental restraints.
• Front outboard safety belts with pretensioners, energy management
retractors, and safety belt usage sensors.
• Driver’s seat position sensor.
• Front crash severity sensor.

•Front passenger sensing system
• Passenger Airbag Off indicator light.
• Restraints Control Module (RCM) with impact and safing sensors.
• Restraint system warning light and back-up tone.
• The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights.
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
classification and conditions. A collection of crash and occupant sensors
provides information to the Restraints Control Module (RCM). During a
crash, the RCM activates the safety belt pretensioners and/or either
none, one, or both stages of the dual-stage airbag supplemental restraints
based on crash severity and occupant classification and 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 and
pretensioners 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.
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 to Airbag 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.
NEVER place 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: Always transport children 12 years old and under
in the back seat and always properly use appropriate child
restraints.
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 theAirbag
supplemental restraint system (SRS) 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 Systemto tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer to Safety belt usage sensors later in this chapter.
Front outboard 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 when the
vehicle is equipped with the Safety Canopy system. This maximizes 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.
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 Energy management retractors 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 lights and chimes section 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, front
passenger sensing system, 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.
• 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 precautionsWARNING: Always drive and ride with your seatback upright
and the lap belt snug and low across the hips.
WARNING: To reduce the risk of injury, make sure children sit
where they can be properly restrained.
WARNING: Never let a passenger hold a child on his or her lap
while the vehicle is moving. The passenger cannot protect the
child from injury in a collision.
WARNING: Never adjust the driver’s seat or seatback when the
vehicles is moving. Adjusting the driver’s seat while the vehicle
is moving is dangerous. The driver could lose control of the
vehicle and have an accident. Adjust the driver’s seat only when
the vehicle is stopped.
WARNING: It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or killed. Do
not allow people to ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure everyone in your
vehicle is in a seat and using a safety belt properly.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety
belt.
WARNING: Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one
tongue that are designed to be used as a pair. 1) Use the
shoulder belt on the outside shoulder only. Never wear the
shoulder belt under the arm. 2) Never swing the safety belt
around your neck over the inside shoulder. 3) Never use a
single belt for more than one person.
