Driving Trailer lamps Trailer lamps are required on most towed vehicles. Make sure your trailer lamps conform to Federal and local regulations. See your dealer or trailer rental agency for the proper instructions and equipment for hooking up trailer lamps. Do not hook the trailer lamps directly into the vehicle's lighting system wiring. If the trailer lamps are not installed properly, the warning lights in the instrument cluster may not work properly. Driving while you tow Do not drive faster than 88km/h (55 mph) while towing a trailer. Do not drive faster than 72 km/h (45 mph) while towing in hilly country or on hot days. Speed control may shut off if you are towing on very long, steep grades. When towing a trailer: • Use D (3rd gear) rather than D (Overdrive) while 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. 114
