UNDERSTANDING THE FEATURES OF YOUR VEHICLE 157 ROOF LUGGAGE RACK - IF EQUIPPED 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 luggage rack, do not exceed the rated vehicle capacity. This vehicle is not equipped with roof rack cross rails as built, unless ordered as optional equipment. Cross rails must be installed prior to carrying loads on the roof rack. If not equipped, your authorized dealer can order and install Mopar௡ cross rails built specifically for this roof rack system or a number of after market rails that are tailored to your life-style or activities. NOTE: The optional cross rails have seven specific locations identified by a feature on both the side rail and the cross rail. Cross rails must be secured in one of the seven detent locations on the side rail to prevent movement with a sudden stop. For improved windnoise performance when cross rails are not in use, place them in detent positions #2 (second detent from the front of the vehicle) and #7 (detent closest to the rear of the vehicle) as indicated with a unique feature on the side rails. 3
