FORD 2002 Expedition - Manual (Page 183)

Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper has a 1 814
kg (4 000 lb.) trailer weight and 181 kg (400 lb.) tongue weight
capability.
Use a frame-mounted weight distributing hitch for trailers over 1 814 kg
(4 000 lb).
Driving while you tow
When towing a trailer:
• Ensure that you turn off your speed control. The speed control may
shut off automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
• Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.
