Folding The Cargo Cover

ROOF LUGGAGE RACK — IF EQUIPPED
The crossbars and siderails are designed to carry
loads on vehicles equipped with a luggage rack.
The load must not exceed 150 lb (68 kg), and
should be uniformly distributed over the luggage
rack crossbars.
NOTE:See an authorized dealer to 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. Place one crossbar in the
forward position. Place the rear crossbar in one of
the two rear optional positions based on the load
being secured.1 — Remove Cover From Vehicle
2 — Twist Cover
3 — Push Twisted Cover Inward
4 — Place Folded Cover In Pouch
WARNING!
In a collision, a loose cargo cover in the vehicle
could cause injury. It could fly around in a

(Continued)
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 with the wrench to lock the crossbar into
position.
NOTE:If any cargo (or any metallic object) is placed over
the satellite radio antenna (if equipped), you may
experience interruption of satellite radio reception.
For improved satellite radio reception, place the
rear crossbar in the forward of the two rear
crossbar positions.
WARNING!
Cargo must be securely tied down before driving
your vehicle. Improperly secured loads can fly off
the vehicle, particularly at high speeds, resulting
in personal injury or property damage. Follow
the roof rack cautions 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.
Long loads which extend over the windshield,
such as wood panels or surfboards, or loads
with large frontal area should be secured to
both the front and rear of the vehicle.
Travel at reduced speeds and turn corners
carefully when carrying large or heavy loads
on the roof rack. Wind forces, due to natural
causes or nearby truck traffic, can add sudden
upward lift to a load. This is especially true on
large flat loads and may result in damage to
the cargo or your vehicle.
The use of vehicle systems that would adjust
the ride heights (such as Selec-Terrain modes
Rock or Sand/Mud) is not recommended
when using the Roof Luggage Rack to carry a
load.
CAUTION!

GETTING TO KNOW YOUR INSTRUMENT PANEL107
When load reduction is activated, the message
“Battery Saver On” or “Battery Saver Mode” will
appear in the instrument cluster.
These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.
NOTE:
The charging system is independent from load
reduction. The charging system performs a diag -
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 109.
The electrical loads that may be switched off (if
equipped), and vehicle functions which can be
affected by load reduction:
Heated Seat/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt AC Power Inverter System
Audio and Telematics System Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capability
of the charging system. The charging system is
still functioning properly.
Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior
lights, overloaded power outlets +12 Volt, 115
Volt AC, USB ports) during certain driving condi
-
tions (city driving, towing, frequent stopping,
etc.).
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appliances
like vacuum cleaners, game consoles and
similar devices. What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte
-
rior)
Check what may be plugged in to power
outlets +12 Volt, 115 Volt AC, USB ports
Check HVAC settings (blower, temperature)
Check the audio settings (volume)
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips, and if the evaluation and driving pattern of
the vehicle did not help to identify the cause.
