Trailer brakes Separate trailer brakes are required on most trailers weighing over 1,500 lbs. (680 kg). RWARNING 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. Trailer Lamps Make sure your trailer lamps conform to federal and local regulations. Class I Trailer Tow electrical wiring provides two circuits (right hand and left hand) to operate trailer stop/turn tail lamps. Each stop/turn circuit will operate one combination stop/turn light bulb (# 1157, 3157, 2357, or 3357) on the trailer. Never add more than one trailer light bulb to one circuit. RWARNING Always replace a fuse with one that has the specified amperage rating. Using a fuse with a higher amperage rating can cause severe wire damage and could start a fire. Driving While You Tow Be especially careful when driving while you tow a trailer. Never drive faster than 45 mph (72 km/h) when you tow in hilly country on hot days. Also, anticipate stops so that you can brake gradually. If you use the speed control while you are towing on very long, steep grades, the speed control may shut off automatically. 226
