ROOF LUGGAGE RACK — IF EQUIPPED
Your vehicle may be equipped with a Roof Luggage Rack
for transporting accessories.
Crossbars should always be used whenever cargo is
placed on the Roof Luggage Rack. Check the straps
frequently to be sure that the load remains securely
NOTE: Crossbars can be purchased at a authorized
dealer through Mopar® parts. External racks do not
increase the total load carrying capacity of the vehicle. Be
sure that the total occupant and luggage load inside the
vehicle, plus the load on the Roof Luggage Rack, do not
exceed the maximum vehicle load capacity.
The load carried on the roof, when equipped with a
luggage rack, must not exceed 150 lbs (68 kg), and it
should be uniformly distributed over the cargo area.
