Maintenance and Specifications BRAKE/CLUTCH FLUID Brake and clutch (if equipped) systems are supplied from the same reservoir. 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 an underhood 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 and, if required, 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. 298 2011 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)
