Tires, Wheels and Loading • Turn off the speed control. The speed control may shut off automatically when you are towing on long, steep grades. • To eliminate excessive transmission shifting, activate the Tow/Haul feature. This will also assist in transmission cooling. For additional information, refer to Automatic transmission operation in the Driving chapter. • Anticipate stops and brake gradually. • Do not exceed the GCWR rating or transmission damage may occur. • Your vehicle may be equipped with a temporary or conventional spare tire. If the spare tire is different in size (diameter and/or width), tread type (All-Season or All-Terrain) or is from a different manufacturer other than the road tires on your vehicle, your spare tire is considered "temporary". Consult information on the spare Tire Label or Safety Compliance Certification Label for limitations when using. 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 safety tips General • Ensure that the trailer, safety chains and 7-pin electrical connectors are securely fastened. • Make sure the truck receiver, draw bar, and coupler are properly connected and adjusted. • Check rear view and side mirrors for proper visibility especially when towing trailer wider than the truck. • When turning make wide turns to allow trailer tires to properly clear any obstacles. • When towing, operate the vehicle at lower speeds than you would when not towing a trailer. The likelihood of trailer sway is greater at higher speeds. • Be prepared for trailer sway due to buffeting when larger vehicles pass in either direction. • If you will be towing a trailer frequently in hot weather, hilly conditions, at GCWR, or any combination of these factors, consider refilling your rear axle with synthetic gear lubricant if not already so 260 2010 F-250/350/450/550 (f23) Owners Guide, 2nd Printing USA (fus)
