1Ford recommends using Motorcraft (Ford) DOT 4 LV High Performance Brake Fluid or
equivalent meeting WSS-M6C65-A2. Use of any fluid other than the recommended fluid may
cause degraded brake performance and not meet the Ford performance standards. Keep brake
fluid clean and dry. Contamination with dirt, water, petroleum products or other materials may
result in brake system damage and possible failure.2Add the coolant type originally equipped in your vehicle.3Use of synthetic or synthetic blend motor oil is not mandatory. Your engine has been designed
to use Motorcraft engine oils or equivalent oils that meet Ford specifications. It is also acceptable
to use an engine oil of recommended viscosity grade that meets API SN requirements and
displays the API Certification Mark for gasoline engines.4Do not use supplemental engine oil additives in your engine. They are unnecessary and could
lead to engine damage that is not covered by your Ford warranty.5Do not use API S category oils labeled as SN, SM, SL or lower category unless the label also
display the API certification mark. These oils do not meet the requirements of the engine and
emission systems.6Automatic transmissions that require MERCON LV should only use MERCON LV fluid. Refer to
scheduled maintenance informationto determine the correct service interval. Use of any fluid
other than the recommended fluid may cause transmission damage.7See your authorized dealer for fluid level checking or filling.8Fill Dana rear axles to 1/4 inch to 9/16 inch (6 mm to 14 mm) below bottom of fill hole.9Optional fuel tank 55.0 gallons (208.0L).10
