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.
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 approxi-
mately 24 in (61 cm) apart. Optimal noise reduction
can then be achieved by adjusting the front crossbar
forward or aft using increments of 1 in (2.5 cm).
• If the rear crossbar (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, avoid placing the
rear crossbar over the satellite radio antenna.
• The grab handles on the back of the vehicle (if
equipped) are not to be used as a towing feature.
