Your vehicle is fitted with a Motorcraftmaintenance-free battery which normallydoes not require additional water.
When a battery replacement is required, youmust use a recommended replacementbattery that matches the electricalrequirements of the vehicle.
Note:After cleaning or replacing the battery,make sure you reinstall the battery cover orshield.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect the low voltage battery performanceand durability. This may also affect theperformance of other electrical systems inthe vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically controlled by a computer, somecontrol conditions are maintained by powerfrom the battery. When the battery isdisconnected or a new battery is installed,the engine must relearn its idle and fuel trimstrategy for optimum driveability andperformance. Flexible fuel vehicles (FFV)must also relearn the ethanol content of thefuel for optimum driveability andperformance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 104). Resetthe radio station presets. See AudioSystem (page 434).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim and fueltrim strategy.
Note:If you do not allow the engine torelearn the idle and fuel trim strategy, theidle quality of your vehicle may be adverselyaffected until the engine computereventually relearns the idle trim and fuel trimstrategy.
