Infants And Child Restraints
Safety experts recommend that children ride rearward-
facing in the vehicle until they are two years old or until
they reach either the height or weight limit of their rear
facing child safety seat. Two types of child restraints can
be used rearward-facing: infant carriers and convertible
child seats.
The infant carrier is only used rearward-facing in the
vehicle. It is recommended for children from birth until
they reach the weight or height limit of the infant carrier.
Convertible child seats can be used either rearward-
facing or forward-facing in the vehicle. Convertible child
seats often have a higher weight limit in the rearward-
facing direction than infant carriers do, so they can be
used rearward-facing by children who have outgrown
their infant carrier but are still less than at least two years
old. Children should remain rearward-facing until they
reach the highest weight or height allowed by their
convertible child seat. Both types of child restraints areheld in the vehicle by the lap/shoulder belt or the
LATCH child restraint anchor system. Refer to “Lower
Anchors and Tether for CHildren (LATCH)”.
WARNING!
•Rearward-facing child seats must never be used in
the front seat of a vehicle with the front passenger
air bag. An air bag deployment could cause severe
injury or death to infants in this position.
•Improper installation can lead to failure of an
infant or child restraint. It could come loose in a
collision. The child could be badly injured or
killed. Follow the manufacturer’s directions ex-
actly when installing an infant or child restraint.

WARNING! (Continued)
•A rearward-facing infant restraint should only be
used in a rear seat. A rearward-facing infant re-
straint in the front seat may be struck by a deploy-
ing passenger air bag which may cause severe or
fatal injury to the infant.
Here are some tips for getting the most out of your child
restraint:
•Before buying any restraint system, make sure that it
has a label certifying that it meets all applicable Safety
Standards. Chrysler Group LLC also recommends that
you try a child restraint in the vehicle seats where you
will use it before you buy it.
•The restraint must be appropriate for your child’s
weight and height. Check the label on the restraint for
weight and height limits.
•Carefully follow the instructions that come with the
restraint. If you install the restraint improperly, it may
not work when you need it.
•The second row seating positions are equipped with
Automatic Locking Retractors (ALR). To install child
restraint seats pull the belt from the retractor until
there is enough allowance to pass it through the child
restraint and slide the latch plate into the buckle. Then,
pull the shoulder belt until it is fully extended from the
retractor. Allow the belt to return into the retractor,
pulling on the excess webbing to tighten the lap
portion around the child restraint. For additional
information, refer to Automatic Locking Retractors
Mode earlier in the Occupant Restraints Section of the
owners’ manual.
•Buckle the child into the restraint exactly as the
manufacturer’s instructions tell you.

WARNING!
When your child restraint is not in use, secure it in
the vehicle with the seat belt or remove it from the
vehicle. Do not leave it loose in the vehicle. In a
sudden stop or accident, it could strike the occupants
or seatbacks and cause serious personal injury.
NOTE: For additional information, refer to
www.seatcheck.org or call 1–866–SEATCHECK. Cana-
dian residents should refer to Transport Canada’s web-
site for additional information: http://www.tc.gc.ca/

Older Children And Child Restraints
Children who are two years old or who have outgrown
their rear-facing convertible child seat can ride forward-
facing in the vehicle. Forward-facing child seats and
convertible child seats used in the forward-facing direc-
tion are for children who are over two years old or who have outgrown the rear-facing weight or height limit of
their rear-facing convertible child seat. Children should
remain in a forward-facing child seat with a harness for
as long as possible, up to the highest weight or height
allowed by the child seat. These child seats are also held
in the vehicle by the lap/shoulder belt or the LATCH
child restraint anchorage system. Refer to “Lower An-
chors and Tether for CHildren (LATCH)”.
All children whose weight or height is above the
forward-facing limit for the child seat should use a
belt-positioning booster seat until the vehicle’s seat belts
fit properly. If the child cannot sit with knees bent over
the vehicle’s seat cushion while the child’s back is against
the seatback, they should use a belt-positioning booster
seat. The child and belt-positioning booster seat are held
in the vehicle by the lap/shoulder belt.
84 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Service ACC Warning
If the system turns off, and the EVIC displays “ACC/
FCW Unavailable Service Radar Sensor”, it indicates
there is an internal system fault. Although the vehicle is
still drivable under normal conditions, have the system
checked by an authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Adding A Trailer Hitch
The weight of a trailer/hitch may affect the performance
of ACC. If there is a noticeable change in performance
following the installation of a trailer/hitch, or if the ACC
performance does not return to normal after removing
the trailer/hitch see your authorized dealer.

Cargo Tie-Down Hooks
The cargo tie-downs, located on the cargo area floor,
should be used to safely secure loads when the vehicle is
moving.WARNING!
•To help protect against personal injury, passengers
should not be seated in the rear cargo area. The
rear cargo space is intended for load carrying
purposes only, not for passengers, who should sit
in seats and use seat belts.
•Cargo tie-down hooks are not safe anchors for a
child seat tether strap. In a sudden stop or acci-
dent, a hook could pull loose and allow the child
seat to come loose. A child could be badly injured.
Use only the anchors provided for child seat
tethers.
The weight and position of cargo and passengers
can change the vehicle center of gravity and ve-
hicle handling. To avoid loss of control resulting
in personal injury, follow these guidelines for
loading your vehicle:(Continued)

WARNING! (Continued)
•Do not carry loads which exceed the load limits
described on the label attached to the left door or
left door center pillar.
•Always place cargo evenly on the cargo floor. Put
heavier objects as low and as far forward as
possible.
•Place as much cargo as possible in front of the rear
axle. Too much weight or improperly placed
weight over or behind the rear axle can cause the
rear of the vehicle to sway.
•Do not pile luggage or cargo higher than the top of
the seatback. This could impair visibility or be-
come a dangerous projectile in a sudden stop or
accident.
REAR WINDOW FEATURES
Rear Window Wiper/Washer

NOTE:To prevent excessive battery drain, use the rear
window defroster only when the engine is operating.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.
•Do not use scrapers, sharp instruments, or abra-
sive window cleaners on the interior surface of the
window.
•Keep all objects a safe distance from the window.
ROOF LUGGAGE RACK — IF EQUIPPED
The crossbars and siderails are designed to carry the
weight on vehicles equipped with a luggage rack. The
load must not exceed 150 lbs (68 kg), and should be
uniformly distributed over the luggage rack crossbars.
NOTE: If not equipped with crossbars, your authorized
dealer can order and install MOPAR crossbars built
specifically for this roof rack system.
Distribute cargo weight evenly on the roof rack crossbars.
The roof rack does not increase the total load carrying
capacity of the vehicle. Be sure the total load of cargo
inside the vehicle plus that on the external rack does not
exceed the maximum vehicle load capacity.

(MDS) (if equipped) allows the engine to operate on four
cylinders, or if you are driving in a fuel efficient manner.
This feature allows you to monitor when you are driving
in a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy.Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. DTE cannot be reset through the SELECT
button.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles (48 km)
estimated driving distance, the DTE display will change
to a “LOW FUEL” message. This display will continue
until the vehicle runs out of fuel. Adding a significant
amount of fuel to the vehicle will turn off the “LOW
FUEL” message and a new DTE value will display.

Off” mode is overcome, turn ESC back on by momen-
tarily pressing the “ESC OFF” switch. This may be done
while the vehicle is in motion.
4WD Low Range
Partial Off
This is the normal operating mode for ESC in 4WD LOW
range. Whenever the vehicle is started in 4WD LOW
range, or the transfer case (if equipped) is shifted from
4WD HIGH range or NEUTRAL to 4WD LOW range, the
ESC system will be in the “Partial Off” mode.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessivelyswaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
to “Trailer Towing” in “Starting and Operating” for
further information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash, the
engine power may be reduced and you may feel the
brakes being applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled when the
ESC system is in the “Partial Off” mode.WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
