and safety warnings 
Loads can only be attached securely when the roof carrier system is fitted correctly  .
Maximum permissible roof load
The maximum permitted roof load is 75 kg. The roof load limit refers to the combined weight of the roof carrier and the load carried on the roof  .
Ensure that you know the weight of the roof rack and the items to be transported on the roof, and weigh them if necessary. Never exceed the maximum permissible roof load.
To secure the front mount, remove the plastic screws from the holes.
However, you will not be able to carry the maximum roof load if you are using a roof carrier with a lower weight rating. In this instance, do not exceed the maximum weight limit for the roof carrier. This weight limit is listed in the fitting instructions.
Distributing the load
Distribute the load evenly and secure it correctly  .
Checking the fittings
After the mounts and roof carrier have been attached, check the bolted connections and fastenings once you have travelled a short distance and then at regular intervals.
