Driving trailer rental agency for proper instructions and equipment for hooking up trailer lamps. Driving while you tow Do not drive faster than 88 km/h (55 mph) when towing a trailer. Speed control may shut off if you are towing on long, steep grades. When 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. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to the Severe Duty Schedule in your "Service Guide" for more information. Towing behind another vehicle Do not tow your vehicle behind another vehicle, such as an RV, unless front wheel dollies are used. Your vehicle cannot be flat towed with all wheels on the ground. Trailer towing tips • Practice turning, stopping and backing up in an area before starting on a trip to get the feel of the vehicle trailer combination. When turning, make wider turns so the trailer wheels will clear curbs and other obstacles. • Allow more distance for stopping with a trailer attached. • The trailer tongue weight should be 10-15% of the loaded trailer weight. • After you have traveled 80 km (50 miles), thoroughly check your hitch, electrical connections and trailer wheel lug nuts. • When stopped in traffic for long periods of time in hot weather, place the gearshift in P (Park) and increase idle speed. This aids engine cooling and air conditioner efficiency. • Vehicles with trailers should not be parked on a grade. If you must park on a grade, place wheel chocks under the trailer's wheels. 110
