Batteries normally produce explosivegases which can cause personalinjury. Therefore, do not allowflames, sparks or lighted substances tocome near the battery. When working nearthe battery, always shield your face andprotect your eyes. Always provide correctventilation.
When lifting a plastic-cased battery,excessive pressure on the end wallscould cause acid to flow through thevent caps, resulting in personal injury anddamage to the vehicle or battery. Lift thebattery with a battery carrier or with yourhands on opposite corners.
Keep batteries out of reach ofchildren. Batteries contain sulfuricacid. Avoid contact with skin, eyes orclothing. Shield your eyes when workingnear the battery to protect against possiblesplashing of acid solution. In case of acidcontact with skin or eyes, flushimmediately with water for a minimum of15 minutes and get prompt medicalattention. If acid is swallowed, call aphysician immediately.

Your vehicle has a Motorcraft®maintenance-free battery which normallydoes not require additional water duringits life of service.
Note:If your vehicle's battery has a coveror shield, make sure it is reinstalled after thebattery has been cleaned or replaced.
Note:See an authorized dealer for lowvoltage battery access, testing, orreplacement.
When a low voltage battery replacementis necessary, see an authorized dealer toreplace the low voltage battery with a Fordrecommended replacement low voltagebattery that matches the electricalrequirements of the vehicle.
To ensure proper operation of the batterymanagement system (BMS), do not allowa technician to connect any electricaldevice ground connection directly to thelow voltage battery negative post. Aconnection at the low voltage batterynegative post can cause inaccuratemeasurements of the battery conditionand potential incorrect system operation.
Note:If a person adds electrical orelectronic accessories or components to thevehicle, the accessories or components mayadversely affect the low voltage batteryperformance and durability and may alsoaffect the performance of other electricalsystems in the vehicle.
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.

When a battery replacement is required,the battery should only be replaced witha Ford recommended replacement batterythat matches the electrical requirementsof the vehicle.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings aremaintained by power from the low voltagebattery. Some engine computer settings,like the idle trim and fuel trim strategy,optimize the driveability and performanceof the engine. Some other computersettings, like the clock and radio stationpresets, are also maintained in memory bypower from the low voltage battery. Whena technician disconnects and connects thelow voltage battery, these settings areerased. Complete the following procedurein order to restore the settings:
1.With the vehicle at a complete stop,set the parking brake.
2.Shift into park (P).
3.Switch off all accessories.
4.Fully press the brake pedal and startthe vehicle.
5.Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 281). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 82).Reset the radio station presets. SeeAudio System (page 281).
6.Allow the engine to idle for at least oneminute. If the engine turns off, pressthe accelerator pedal to start theengine.
7.While the engine is running, press thebrake pedal and shift into neutral (N).
8.Allow the engine to run for at least oneminute by pressing on the acceleratorpedal.
9.Drive the vehicle at least 12 mi (20 km)to completely relearn the idle 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 fueltrim strategy.
Make sure that you dispose of old batteriesin an environmentally friendly way. Seekadvice from your local authority aboutrecycling old batteries.
