TRAILER TOWING
Your vehicle is classified as a light duty towing
vehicle. The amount of weight you can safely tow
depends on the type of engine you have in your
vehicle. Your vehicle does not come from the factory
fully equipped to tow. No towing packages are
available through Ford or Mercury/Lincoln dealers.
Do not tow a trailer until your vehicle has been
driven at least 800 km (500 miles). If towing with a
station wagon, inflate the rear tires to 35 psi.
Towing a trailer places an additional load on your
vehicle's engine, transaxle, brakes, tires and
suspension. Inspect these components carefully after
towing.
In order to identify your vehicle's engine, refer to
Identifying components in the engine
compartment in the Maintenance and Care chapter.
The amount of weight that you can tow depends on
the type of engine in your vehicle. See the following
