FORD 2007 Edge v.1 - Manual (Page 107)

When loading the luggage rack, it is recommended to evenly distribute
the load, as well as maintain a low center of gravity. Ensure that the load
is securely fastened. The maximum load for the roof rack is 100 lbs
(44 kg).
Your fuel economy will decrease when you drive with items on the
luggage rack. When the rack is loaded, check the tightness of the load
before driving and at each refueling stop.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
