WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment. Do not tow with a slingbelt. Ford Motor Company has not
approved a slingbelt towing procedure. Also, wrecker towing the vehicle
by the frame-mounted tow hooks is not recommended or advised.
If your vehicle is equipped with air suspension, the air suspension
control and the ignition must be turned off before being towed.
Refer to Air suspension in the Driving chapter.
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.
On 4x4 vehicles, it is recommended that your vehicle be towed with a
wheel lift and dollies or flatbed equipment with all the wheels off the
ground.
