Tires, Wheels and Loading • Under extreme conditions with large frontal trailers, high outside temperatures and highway speeds, the coolant gauge may indicate higher than normal coolant temperatures. If this occurs, reduce speed until the coolant temperature returns to the normal range. Refer to Gauges in the Instrument Cluster chapter. • Allow more distance for stopping with a trailer attached; anticipate stops and brake gradually. 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. • To aid in engine/transmission cooling and A/C efficiency during hot weather while stopped in traffic, place the gearshift lever in P (Park) (automatic transmission) or neutral (manual transmissions). • After you have traveled 50 miles (80 km), thoroughly check your hitch, electrical connections and trailer wheel lug nuts. • 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 lube if not already so equipped. Refer to the Maintenance and Specifications chapter for the lubricant specification. Remember that regardless of the rear axle lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a new vehicle, and that the first 500 miles (800 km) of towing be done at no faster than 70 mph (113 km/h) with no full throttle starts. • 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. When backing down a ramp during boat launching or retrieval: • Do not allow the static water level to rise above the bottom edge of the rear bumper. • Do not allow waves to break higher than 6 in (15 cm) above the bottom edge of the rear bumper. 148 2011 Ranger (ran) Owners Guide, 2nd Printing USA (fus)
