Maintenance axle assembly has been submerged in water. The axle lubricant should be changed any time the rear axle has been submerged in water. Ensure the correct automatic transmission fluid is used. Transmission fluid requirements are indicated on the dipstick or on the dipstick handle. Check the container to verify the fluid being added is of the correct type. Refer to your scheduled maintenance guide to determine the correct service interval. Some transmission fluids may be labeled as dual usage, such as MERCON௡ and MERCON௡ V. These dual usage fluids are not to be used in an automatic transmission that requires use of the MERCON௡ type fluid. However, these dual usage fluids may be used in transmissions that require the MERCON௡ V type fluid. MERCON௡ and MERCON௡ V type fluids are not interchangeable. DO NOT mix MERCON௡ and MERCON௡ V. Use of a transmission fluid that indicates dual usage (MERCON௡ and MERCON௡ V) in an automatic transmission application requiring MERCON௡ may cause transmission damage. Use of any fluid other than the recommended fluid may cause transmission damage. 4 Approximate dry fill capacity including transmission fluid cooling system, actual refill capacities will vary based on vehicle application and transmission fluid cooling system (i.e. coolers size, cooling lines. auxiliary cooler capacities). The amount of transmission fluid and fluid level should be set by the indication on the dipstick's normal operating range. 5 Use of synthetic or synthetic blend motor oil is not mandatory. Engine oil need only meet the requirements of Ford specification WSS-M2C153-H and the API Certification mark. OCTANE RECOMMENDATIONS Your vehicle is designed to use "Premium" unleaded gasoline with an (R+M)/2 octane rating of 91 or higher for optimum performance. (R+M)/2 METHOD The use of gasolines with lower octane ratings may degrade performance. We do not recommend the use of gasolines labeled as "Premium" in high altitude areas that are sold with octane ratings of less than 91. If your engine knocks under any driving conditions while you are using fuel with the recommended octane rating, see your dealer or a qualified service technician to prevent any engine damage. 3 91 16
