DO NOT TOW WITH SLINGBELT EQUIPMENT.
Ford Motor Company has not developed or
approved a T-hook sling-type procedure. Use wheel
lift or flatbed equipment. When towing your Mark
VIII with wheel lift equipment, be sure dollies are
in place under the trailing wheels if the air
suspension is deflated to prevent damage to the air
deflector.

truck driver refer to this manual for the proper
hook-up and towing procedures for your vehicle.
