The liftgate door and window should be closed before driving. If not,
possible damage may occur to your vehicle.
Always close liftgate window before opening liftgate. Liftgate
glass and liftgate should never be open at the same time. Failure
to observe this warning may result in personal injury or damage to
your vehicle.
Make sure the liftgate door and/or window are closed to prevent
exhaust fumes from being drawn into the vehicle. This will also
reduce the risk of passengers and cargo falling out.
CARGO COVER (IF EQUIPPED)
Your vehicle may be equipped with a cargo area cover that covers the
luggage compartment of your vehicle.
To install the cover:
Push both ends of the cover into the
depressions (right side first) in the
trim panels behind the second row
seat.
To reduce the risk of
injuries, the cargo area
cover must be properly installed
on the rear trim panels.
Do not place any objects on the cargo area cover. They may
obstruct your vision or strike occupants of the vehicle in the
case of a sudden stop or collision.
Cargo management system
The cargo management system consists of storage compartments located
in the floor of the rear cargo area.

Before returning the seatback to its original position, make sure
that cargo or any objects are not trapped underneath the
seatback. After returning the seatback to its original position, pull on
the seatback to ensure that it has fully latched. An unlatched seat may
become dangerous in the event of a sudden stop or collision.
SAFETY RESTRAINTS
Personal Safety System
The Personal Safety Systemprovides 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 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 Systemconsists of:
•Driver and passenger dual-stage airbag supplemental restraints.
•Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
•Driver’s seat position sensor.
•Front crash severity sensor.
•Restraints Control Module (RCM).
•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 Systemwork?
The Personal Safety Systemcan 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 activates 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 Systemdetermined

Front safety belt energy management retractors
The front 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 toSafety restraintssection in
this chapter.
Determining if the Personal Safety Systemis operational
The Personal Safety Systemuses 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 Systemis 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:
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after the 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 Systemserviced at your dealership or by a qualified technician
immediately. Unless serviced, the system may not function properly in
the event of a collision.
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit in the back
seat where they can be properly restrained.

Safety belt height adjustment
Your vehicle has safety belt height
adjustments for the front and
second row outboard seating
positions.
Adjust the height of the shoulder
belt so the belt rests across the
middle of your shoulder.
To adjust the shoulder belt height,
squeeze the button and slide the
height adjuster up or down. Release
the button and pull down on the
height adjuster to make sure it is locked in place.
Position the safety belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the safety belt and
increase the risk of injury in a collision.
Safety belt extension assembly
If the safety belt is too short when fully extended, there isa8inch(20
cm) safety belt extension assembly that can be added (part number
611C22). This assembly can be obtained from your dealer at no cost.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.
