Connecting the trailer's brakes Electric brakes and manual, automatic, or surge-type hydraulic brakes are safe if you install them properly and adjust them according to the manufacturer's instructions. Be sure that your trailer's brakes meet local and federal regulations. Separate trailer brakes of adequate size should be used for trailers weighing over 1,000 lbs. (454 kg) loaded weight. WARNING 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. Connecting the trailer's lights Do not connect a trailer's lighting system wiring directly to your vehicle's lighting system wiring. To get the proper equipment for hooking up your trailer's lights, see your local trailer dealer and your Ford dealer. Be sure to follow their instructions carefully. If you do not install trailer lights correctly, you may cause damage to the vehicle's lighting system. Driving While You Tow Be especially careful when driving while you tow a trailer. Never drive faster than 45 mph (70 km/h) when you tow in hilly country on hot days. Also, anticipate stops so that you can brake gradually. When you tow down steep grades, move the gearshift to 1 (Low). It gives more engine braking to slow your vehicle than Drive on the downgrades. 187
