Note:Battery posts, terminals and relatedaccessories contain lead and leadcompounds. Wash hands after handling.
Note:Electrical or electronic accessoriesor components added to the vehicle by thedealer or the owner may adversely affectbattery performance and durability.
Your vehicle is equipped with a Motorcraftmaintenance-free battery which normallydoes not require additional water duringits life of service.
For longer, trouble-free operation, keep thetop of the battery clean and dry. Also,make certain the battery cables are alwaystightly fastened to the battery terminals.
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.
It is recommended that the negativebattery cable terminal be disconnectedfrom the battery if you plan to store yourvehicle for an extended period of time.
Because your vehicle’s engine iselectronically controlled by a computer,some control conditions are maintainedby power from the battery. When thebattery is disconnected or a new batteryis installed, the engine must relearn its idleand fuel trim strategy for optimumdriveability and performance. To begin thisprocess
1.With the vehicle at a complete stop,set the parking brake.
2.Put the gearshift in park (P) or neutral(N) and turn off all accessories.
3.Start the engine. Run the engine untilit reaches normal operatingtemperature.
4.Allow the engine to idle for at least oneminute.
5.Turn the air conditioning (if equipped)on and allow the engine to idle for atleast one minute.
6.Release the parking brake. With yourfoot on the brake pedal and with theair conditioning on, put the vehicle indrive (D) and allow the engine to idlefor at least one minute.
•If you do not allow the engine torelearn its idle trim, the idle qualityof your vehicle may be adverselyaffected until the idle trim iseventually relearned.
7.Drive the vehicle to complete therelearning process
•The vehicle may need to be driven10 mi (16 km) or more to relearn theidle and fuel trim strategy alongwith the ethanol content for flexiblefuel vehicles.
If the battery has been disconnected or anew battery has been installed, the clockand radio settings must be reset once thebattery is reconnected.
