WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.
If equipped with air suspension, the air suspension control must be
turned to the OFF position.
The Ford approved towing procedure is flatbed or wheel lift with
dollies.
On 4x2 vehicles, it is acceptable to tow the vehicle with the front wheels
on the ground (without dollies) and the rear wheels off the ground.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
Do not tow with slingbelt equipment. Ford Motor Company has not
developed or approved a slingbelt towing procedure.
