Begin with the vehicle’s roof type and approved mounting locations. Crossbars for a gutter, rail, or another mounting arrangement are not interchangeable simply because the vehicles share a brand.
Check the instructions and ratings for the vehicle, roof, bars, mounts, and load carrier. Use the lowest applicable limit and include the weight of the equipment itself. Do not substitute a parked-load figure for a driving limit.
Confirm whether locks are included in the selected version. A lock can deter removal of a component; it does not automatically secure every item carried above it.
Allow clearance for doors, roof panels, and the tailgate. Recheck fixings and load restraint as specified before and during travel.
