Maintenance and Specifications BRAKE FLUID 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 your brake system could be compromised; seek service from your dealer immediately. TRANSAXLE FLUID Checking 6-speed automatic transmission fluid at operating temperature (158°F-176°F [70°C-80°C]) Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transaxle does not consume fluid. However, the fluid level should be checked if the transaxle is not working properly, i.e., if the transaxle slips or shifts slowly or if you notice some sign of fluid leakage. 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]). 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 it reaches normal operating temperature. 2. Park the vehicle on a level surface and engage the parking brake. 239 2005 Montego (mgo) Owners Guide (post-2002-fmt) USA_English (fus)
