Tires, Wheels and Loading Driving while you tow When towing a trailer: • Turn off the 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. • To eliminate excessive shifting, use a lower gear. This will also assist in transmission cooling. (For additional information, refer to Understanding the gearshift positions of the 4-speed automatic transmission in the Driving chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. Servicing after towing If you tow a trailer for long distances, your vehicle will require more frequent service intervals. Refer to your Scheduled Maintenance Information for more information. Trailer towing tips • Practice turning, stopping and backing up 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. • If you are driving down a long or steep hill, shift to a lower gear. Do not apply the brakes continuously, as they may overheat and become less effective. • The trailer tongue weight should be 10-15% of the loaded trailer weight. • After you have traveled 50 miles (80 km), thoroughly check your hitch, electrical connections and trailer wheel lug nuts. • To aid in engine/transmission cooling and A/C efficiency during hot weather while stopped in traffic, place the gearshift lever in P (Park). • 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. Launching or retrieving a boat Disconnect the wiring to the trailer before backing the trailer into the water. Reconnect the wiring to the trailer after the trailer is removed from the water. 254 2005 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
