Maintenance 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: 1. 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 123). Reset the power windows bounce-back feature. See Windows and Mirrors (page 88). Reset the radio station presets. See Audio System (page 123). 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. Note: Always dispose of automotive batteries in a responsible manner. Follow your local authorized standards for disposal. Call your local authorized recycling center to find out more about recycling automotive batteries. 280 MKZ (CC9)
