Wind Buffeting
Wind buffeting can be described as the perception of
pressure on the ears or a helicopter-type sound in the ears.
Your vehicle may exhibit wind buffeting with the windows
down, or the sunroof (if equipped) in certain open or
partially open positions. This is a normal occurrence and
can be minimized. If the buffeting occurs with the rear
windows open, then open the front and rear windows
together to minimize the buffeting. If the buffeting occurs
with the sunroof open, adjust the sunroof opening to
minimize the buffeting or open any window.
Sunshade Operation
The sunshade can be opened manually. However, the
sunshade will open automatically as the sunroof opens.
NOTE:The sunshade cannot be closed if the sunroof is
open.
Pinch Protect Feature
This feature will detect an obstruction in the opening of the
sunroof during Express Close operation. If an obstruction
in the path of the sunroof is detected, the sunroof will
automatically retract. Remove the obstruction if this oc-
curs. NOTE:
If three consecutive sunroof close attempts result in
Pinch Protect reversals, Pinch Protect will disable and the
sunroof must be closed in Manual Mode.
Venting Sunroof — Express
Push and release the Vent button within one half second
and the sunroof will open to the vent position. This is
called “Express Vent” and it will occur regardless of
sunroof position. During Express Vent operation, any
movement of the switch will stop the sunroof.
Sunroof Maintenance
Use only a non-abrasive cleaner and a soft cloth to clean the
glass panel.
Ignition Off Operation
NOTE:
• The power sunroof switch can remain active in Acces-
sory Delay for up to approximately ten minutes after the
vehicle’s ignition is placed to the OFF position. Opening
either front door will cancel this feature.
• This feature is programmable using the Uconnect Sys-
tem. Refer to “Uconnect Settings” in “Multimedia” for
further information.

WARNING!
•Never leave children unattended in a vehicle, or with
access to an unlocked vehicle. Never leave the key
fob in or near the vehicle, or in a location accessible
to children. Do not leave the ignition of a vehicle
equipped with Keyless Enter-N-Go in the ACC or
ON/RUN mode. Occupants, particularly unattended
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.
Opening Sunroof
The sunroof has two programmed automatic stops for the
sunroof open position; a comfort stop position and a full
open position. The comfort stop position has been opti-
mized to minimize wind buffeting.
Express
Push the switch rearward and release it within one-half
second. The sunroof will open automatically to the comfort
stop position. Push the switch rearward and release it
again, the sunroof will open to the full open position and
automatically stop. This is called “Express Open”. During
Express Open operation, any movement of the sunroof
switch will stop the sunroof.
Manual Mode
To open the sunroof, push and hold the switch rearward.
The sunroof will stop automatically at the comfort stop
position. Push and hold the switch rearward again, the
sunroof will open to the full open position and automati-
cally stop. Any release of the switch will stop the move-
ment. The sunroof and sunshade will remain in a partially
opened condition until the switch is pushed and held
rearward again.

Retractable Cargo Area Cover — If Equipped
NOTE:The purpose of this cover is for privacy, not to
secure loads. It will not prevent cargo from shifting or
protect passengers from loose cargo.
To cover the cargo area:
1. Grasp the cover at the center handle. Pull it over the cargo area.
2. Insert the pins on the ends of the cover into the slots in the pillar trim cover. 3. The liftgate may be opened with the cargo cover in
place.
WARNING!
In a collision, a loose cargo cover in the vehicle could
cause injury. It could fly around in a sudden stop and
strike someone in the vehicle. Do not store the cargo
cover on the cargo floor or in the passenger compart-
ment. Remove the cover from the vehicle when taken
from its mounting. Do not store it in the vehicle.

Rear Cargo Tie-Downs
The rear 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

WARNING! (Continued)
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 accident, 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 vehicle han-
dling. To avoid loss of control resulting in personal
injury, follow these guidelines for loading your vehicle:
• 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 become
a dangerous projectile in a sudden stop or accident.

GARAGE DOOR OPENER — IF EQUIPPED
HomeLink replaces up to three hand-held transmitters that
operate devices such as garage door openers, motorized
gates, lighting or home security systems. The HomeLink
unit is powered by your vehicle’s 12 Volt battery.
The HomeLink buttons, located on the overhead console,
designate the three different HomeLink channels. The
HomeLink indicator is located above the center button.
NOTE:HomeLink is disabled when the Vehicle Security
Alarm is active.
Before You Begin Programming HomeLink
Be sure that your vehicle is parked outside of the garage
before you begin programming.
For more efficient programming and accurate transmission
of the radio-frequency signal it is recommended that a new
battery be placed in the hand-held transmitter of the device
that is being programmed to the HomeLink system.
To erase the channels place the ignition in the ON/RUN
position and push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds or until the orange
indicator flashes.
NOTE:
• Erasing all channels should only be performed when
programming HomeLink for the first time. Do not erase
channels when programming additional buttons.
• If you have any problems, or require assistance, please
call toll-free 1-800-355-3515 or, on the Internet at
HomeLink.com for information or assistance.

2. Push and hold the desired HomeLink button until the indicator light begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button proceed with “Canadian/ Gate Operator Programming” step 2 and follow all
remaining steps.Using HomeLink
To operate, push and release the programmed HomeLink
button. Activation will now occur for the programmed
device (i.e. garage door opener, gate operator, security
system, entry door lock, home/office lighting, etc.) The
hand-held transmitter of the device may also be used at
any time.
Security
It is advised to erase all channels before you sell or turn in
your vehicle.
To do this, push and hold the two outside buttons for 20
seconds until the orange indicator flashes. Note that all
channels will be erased. Individual channels cannot be
erased.
The HomeLink Universal Transceiver is disabled when the
Vehicle Security Alarm is active.

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.
To move the crossbars, loosen the attachments, located at
the upper edge of each crossbar, approximately eight turns
using the anti-theft wrench provided with the MOPAR
crossbars. Then, move the crossbar to the desired position,
keeping the crossbars parallel to the rack frame. Once the
crossbar is in the desired position, retighten the with the
wrench to lock the crossbar into position.
NOTE:
•To help control wind noise when the crossbars are not in
use, place the front and rear crossbars approximately 24
inches (61 cm) apart. Optimal noise reduction can then
be achieved by adjusting the front crossbar forward or
aft using increments of 1 inches (2.5 cm).
• If any cargo (or any metallic object) is placed over the
satellite radio antenna (if equipped), you may experi-
ence interruption of satellite radio reception. For im-
proved satellite radio reception, avoid placing the rear
crossbar over the satellite radio antenna.WARNING!
Cargo must be securely tied down before driving your
vehicle. Improperly secured loads can fly off the ve-
hicle, particularly at high speeds, resulting in personal
injury or property damage. Follow the roof rack cau-
tions when carrying cargo on your roof rack.
CAUTION!
• To prevent damage to the roof of your vehicle, do not
carry any loads on the roof rack without the crossbars
installed. The load should be secured and placed on
top of the crossbars, not directly on the roof. If it is
necessary to place the load on the roof, place a
blanket or some other protection between the load
and the roof surface.
• To avoid damage to the roof rack and vehicle, do not
exceed the maximum roof rack load capacity of 150 lb
(68 kg). Always distribute heavy loads as evenly as
possible and secure the load appropriately.
