Attaching a roof rack
WARNING Risk of injury if the maximum roof load is exceeded
When you load the roof, the centre of gravity of the vehicle rises and the usual driving characteristics as well as the steering and braking characteristics change. During cornering, the vehicle tilts more strongly and may react more sluggishly to steering movements.
If you exceed the maximum roof load, the driving characteristics, as well as the steering and braking characteristics, will be greatly impaired.
Always comply with the maximum roof load and adjust your driving style.
