Maintenance and Specifications Use of a non-approved automatic transmission fluid may cause internal transmission component damage. If necessary, add fluid in 1/2 pint (250 mL) increments through the filler tube until the level is correct. If an overfill occurs, excess fluid should be removed by an authorized dealer. An overfill condition of transmission fluid may cause shift and/or engagement concerns and/or possible damage. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components. AIR FILTER Refer to scheduled maintenance information for the appropriate intervals for changing the air filter element. When changing the air filter element, use only the air filter element listed. Refer to Motorcraft௡ part numbers in this chapter. WARNING: To reduce the risk of vehicle damage and/or personal burn injuries do not start your engine with the air cleaner removed and do not remove it while the engine is running. Changing the air filter element 1. Release the clamps that secure the air filter housing cover. 2. Carefully separate the two halves of the air filter housing. 3. Remove the air filter element from the air filter housing. 4. Wipe the air filter housing and cover clean to remove any dirt or debris and to ensure good sealing. 5. Install a new air filter element. Be careful not to crimp the filter element edges between the air filter housing and cover. This could cause filter damage and allow unfiltered air to enter the engine if not properly seated. 303 2011 MKZ (378) Owners Guide, 2nd Printing USA (fus)
