Maintenance and Specifications sure to put the cap back on the reservoir. Refer to Maintenance product specifications and capacities in this chapter for the proper fluid type. BRAKE FLUID The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced. Fluid levels between the "MIN" and "MAX" lines are within the normal operating range; there is no need to add fluid. If the fluid levels are outside of the normal operating range the performance of the system could be compromised; seek service from your authorized dealer immediately. TRANSMISSION FLUID Checking automatic transmission fluid The automatic transmission does not have a transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, (i.e., if the transmission slips or shifts slowly) or if you notice some sign of fluid leakage. Transmission fluid should be checked by an authorized dealer. If required, fluid should be added by an authorized dealer. 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 Motorcraft air filter element listed. Refer to Motorcraft part numbers in this chapter. 372 2008 Expedition (exd) Owners Guide (post-2002-fmt) USA (fus)
