FORD 2014 Flex v.2 - Manual (Page 208)

Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder or luggage racks).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
off-highway usage.
