178 UNDERSTANDING THE FEATURES OF YOUR VEHICLE 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. The optional cross rails have five specific locations identified by a feature on both the side rail and the cross rail. Cross rails must be secured in one of the five detent locations on the side rail to prevent movement with a sudden stop. The cross rails must also be installed using the correct orientation (the longer rail toward the front) with the wind trip toward the front of the vehicle as shown below. For improved windnoise performance when cross rails are not in use, place them in detent positions #1 (first detent from the front of the vehicle) and #4 (second detent from the rear of the vehicle) as indicated with a unique feature on the side rails. The grab handles (A) on the back of the vehicle (if equipped) are not to be used as a towing feature. NOTE: If the rear cross rail (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 rail in detent position #4 when not in use. Cross Rail Positions
