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.
The optional crossbars must be installed using the correct
orientation (the longer crossbar toward the front).
The optional crossbars must also be secured in one of the
seven detent positions marked with an arrow on the
siderails to prevent movement. To move the crossbars,
loosen the thumb screws, located at the upper edge of
each crossbar, approximately eight turns, then move the
crossbar to the desired position, keeping the crossbars
parallel to the rack frame. Once the crossbar is in one of
the seven detent positions, retighten the thumb screws to
lock the crossbar into position.
NOTE:
• To help control wind noise when the crossbars are not
in use, place the front crossbar in the second detent
from the front of the vehicle and the rear crossbar in
the last detent closest to the rear of the vehicle.
• 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, place the rear cross-
bar in the second detent from the rear of the vehicle
when not in use.
