Tires, Wheels and Loading 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 500 miles (800 km) of a new vehicle, and that the first 500 miles (800 km) of towing be done at no faster than 70 mph (112 km/h) with no full throttle starts. • 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. 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 inches (15 cm) above the bottom edge of the rear bumper. Exceeding these limits may allow water to enter vehicle components: • causing internal damage to the components. • affecting driveability, emissions and reliability. Replace the rear axle lubricant any time the axle has been submerged in water. Rear axle lubricant quantities are not to be checked or changed unless a leak is suspected or repair required. RECREATIONAL TOWING (ALL WHEELS ON THE GROUND) Follow these guidelines for your specific powertrain combination to tow your vehicle with all four wheels on the ground (such as behind a recreational vehicle). These guidelines are designed to ensure that your transmission is not damaged due to insufficient lubrication. 233 2007 Mountaineer (mnt) Owners Guide (post-2002-fmt) USA (fus)
