WARNING!
•For personal security and safety in the event of a
collision, lock the vehicle doors before you drive as
well as when you park and exit the vehicle.
• When exiting the vehicle, always remove the key fob
from the vehicle and lock your vehicle. If equipped
with Keyless Enter-N-Go — Ignition, always make
sure the keyless ignition node is in “OFF” mode,
remove the key fob from the vehicle and lock the
vehicle. Unsupervised use of vehicle equipment may
cause severe personal injuries or death.
•
Never leave children alone in a vehicle, or with access
to an unlocked vehicle. Allowing children to be in a
vehicle unattended is dangerous for a number of
reasons. A child or others could be seriously or fatally
injured. Children should be warned not to touch the
parking brake, brake pedal or the gear selector.
• Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go — Ignition the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.

door panel. Push the switch to lock or unlock the doors.
NOTE: The key fob may not be able to be detected by the
vehicle keyless-go system if it is located next to a mobile
phone, laptop or other electronic device; these devices may
block the key fob’s wireless signal and prevent the
keyless-go system from starting the vehicle.

WARNING!(Continued)
children, can become entrapped by the power sun-
roof while operating the power sunroof switch. Such
entrapment may result in serious injury or death.
• In a collision, there is a greater risk of being thrown
from a vehicle with an open sunroof. You could also
be seriously injured or killed. Always fasten your
seat belt properly and make sure all passengers are
also properly secured.
• Do not allow small children to operate the sunroof.
Never allow your fingers, other body parts, or any
object, to project through the sunroof opening. In-
jury may result.

Cargo Area Features
Cargo Load Floor
The cargo load floor system has a load capacity of 400 lbs
(181 kg). To provide additional storage area, each rear seat can be
folded flat. This allows for extended cargo space and still
maintains some rear seating room. Refer to “Seats” in this
section for further information.
Cargo Extension Panels
Cargo extension panels can be folded and unfolded. When
the rear seats are moved to the more forward positions and
the rear seat backs are folded down, the extension panels
(2) can be unfolded manually by hand. The extension
panels can be used to extend the load floor to the rear seats
and/or hide the gap between the load floor and rear seats
or to assist in loading large items into the cargo area.
Cargo Tie-Down Hooks And Loops
The tie-downs located on the cargo area floor should be
used to secure loads safely when the vehicle is moving.
Cargo tie-down loops are located on the trim panels.

ROOF LUGGAGE RACK — IF EQUIPPED
The load carried on the roof, when equipped with a
luggage rack, must not exceed 150 lbs (68 kg), and it should
be uniformly distributed over the cargo area.
Crossbars should always be used whenever cargo is placed
on the roof rack. Check the straps frequently to be sure that
the load remains securely attached.
NOTE:Crossbars can be purchased at your authorized
dealer through Mopar parts.
External racks do not increase the total load carrying
capacity of the vehicle. Be sure that the total occupant and
luggage load inside the vehicle, plus the load on the
luggage rack, do not exceed the maximum vehicle load
capacity.

•How far (if at all) the driver was depressing the accel-
erator and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are recorded by
the EDR under normal driving conditions and no personal
data (e.g., name, gender, age, and crash location) are
recorded. However, other parties, such as law enforcement,
could combine the EDR data with the type of personally
identifying data routinely acquired during a crash investi-
gation.
To read data recorded by an EDR, special equipment is
required, and access to the vehicle or the EDR is needed. In
addition to the vehicle manufacturer, other parties, such as
law enforcement, that have the special equipment, can read
the information if they have access to the vehicle or the
EDR.Child Restraints
Everyone in your vehicle needs to be buckled up at all
times, including babies and children. Every state in the
United States, and every Canadian province, requires that
small children ride in proper restraint systems. This is the
law, and you can be prosecuted for ignoring it.
Children 12 years or younger should ride properly buckled
up in a rear seat, if available. According to crash statistics,
children are safer when properly restrained in the rear
seats rather than in the front.

How To Stow An Unused Switchable-ALR (ALR)
Seat Belt:
When using the LATCH attaching system to install a child
restraint, stow all ALR seat belts that are not being used by
other occupants or being used to secure child restraints.
An unused belt could injure a child if they play with it and
accidentally lock the seat belt retractor. Before installing a
child restraint using the LATCH system, buckle the seat
belt behind the child restraint and out of the child’s reach.
If the buckled seat belt interferes with the child restraint
installation, instead of buckling it behind the child re-
straint, route the seat belt through the child restraint belt
path and then buckle it. Do not lock the seat belt. Remind
all children in the vehicle that the seat belts are not toys and
that they should not play with them.

Installing A Child Restraint With A Switchable
Automatic Locking Retractor (ALR):
Child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a
lap/shoulder belt.

WARNING!(Continued)
•If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, or brake fluid leaks are
suspected. The cause should be located and corrected
immediately.
