Maintenance When a low voltage battery replacement is necessary, see an authorized dealer to replace the low voltage battery with a Ford recommended replacement low voltage battery that matches the electrical requirements of the vehicle To ensure proper operation of the battery management system (BMS), do not allow a technician to connect any electrical device ground connection directly to the low voltage battery negative post. A connection at the low voltage battery negative post can cause inaccurate measurements of the battery condition and potential incorrect system operation. Note: If a person adds electrical or electronic accessories or components to the vehicle, the accessories or components may adversely affect the low voltage battery performance and durability and may also affect the performance of other electrical systems in the vehicle. For longer, trouble-free operation, keep the top of the battery clean and dry. Also, make certain the battery cables are always tightly fastened to the battery terminals. If you see any corrosion on the battery or terminals, remove the cables from the terminals and clean with a wire brush. You can neutralize the acid with a solution of baking soda and water. When a battery replacement is required, the battery should only be replaced with a Ford recommended replacement battery that matches the electrical requirements of the vehicle. Because your vehicle's engine is electronically-controlled by a computer, some engine control settings are maintained by power from the low voltage battery. Some engine computer settings, like the idle trim and fuel trim strategy, optimize the driveability and performance of the engine. Some other computer settings, like the clock and radio station presets, are also maintained in memory by power from the low voltage battery. When a technician disconnects and connects the low voltage battery, these settings are erased. Complete the following procedure in order to restore the settings: With the vehicle at a complete stop, set the parking brake. 2. Shift the transmission into P. 3. Turn off all accessories. 4. Step on the brake pedal and start the vehicle. 5. Run the engine until it reaches normal operating temperature. While the engine is warming up, complete the following: Reset the clock. See Audio System (page 266). Reset the power windows bounce-back feature. See Windows and Mirrors (page 77). Reset the radio station presets. See Audio System (page 266). 6. Allow the engine to idle for at least one minute. If the engine turns off, step on the accelerator to start the engine. 7. While the engine is running, step on the brake pedal and shift the transmission to N. 8. Allow the engine to run for at least one minute by pressing on the accelerator pedal. 9. Drive the vehicle at least 10 miles (16 kilometers) to completely relearn the idle and fuel trim strategy. Note: If you do not allow the engine to relearn the idle and fuel trim strategy, the idle quality of your vehicle may be adversely affected until the engine computer eventually relearns the idle trim and fuel trim strategy. 1. 217 Escape/Kuga (TM2)
