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 specifi-
cally 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.
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 inch (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.
