1Ford recommends using Motorcraft (Ford) DOT 4 Low Viscosity 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.2Approximate dry fill capacity. Actual amount may vary during fluid changes.3Automatic 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.4See your authorized dealer for fluid level checking or filling.5Your 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.6Do 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.
