Maintenance and Specifications 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 6-speed automatic transmission fluid 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. Checking automatic transmission fluid at normal operating temperature (140°F-158°F [60°C-70°C]) Automatic transmission fluid expands when warmed. To obtain an accurate fluid check, drive the vehicle until it is warmed up (approximately 20 miles [30 km]) until the engine coolant gauge indicates normal operating temperature. If your vehicle has been operated for an extended period at high speeds, in city traffic during hot weather or pulling a trailer, the vehicle should be turned off for about 30 minutes to allow fluid to cool before checking. 1. Drive the vehicle 20 miles (30 km) or until the coolant gauge indicates normal operating temperature. 2. Park the vehicle on a level surface and engage the parking brake. 3. With the parking brake engaged and your foot on the brake pedal, start the engine and move the gearshift lever through all of the gear ranges. Allow sufficient time for each gear to engage (approximately 10-15 seconds in each position). 4. Move the gearshift lever to P (Park) and leave the engine running. 296 2010 MKZ (378) Owners Guide, 3rd Printing USA (fus)
