Flexible rack system to facilitate roof carrying. Roof rails and cross bars are required for all Land Rover roof mounted accessories. Consideration should always be given to vehicle's maximum roof load capacity to ensure this is not exceeded. Objects placed above the roof mounted satellite antenna may reduce the quality of the signal received by the vehicle and could have a detrimental effect on the navigation and satellite radio systems, if fitted. Some roof carrying accessories may restrict the opening of the vehicle’s sliding sunroof when fitted. Care should be taken when opening the roof to avoid collision with any items fitted above the vehicle.
