Maintenance and Specifications Adjusting automatic transmission fluid levels Before adding any fluid, make sure the correct type is used. The type of fluid used is normally indicated on the dipstick blade and also in the Maintenance product specifications and capacities section in this chapter. 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. 297 2009 Mariner (mrn) Owners Guide, 2nd Printing USA (fus)
