Checking the Inverter SystemController Coolant
When the engine is cold, check theconcentration and level of the invertersystem controller coolant at the intervalslisted in the scheduled maintenanceinformation. See ScheduledMaintenance (page 348).
Note:Make sure that the level is betweenthe MIN and MAX marks on the invertersystem controller coolant reservoir.
Note:Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Note:If the level is at the MIN mark, belowthe MIN mark, or empty, add coolantimmediately. See Adding Inverter SystemController Coolant in this chapter.
The coolant concentration should bemaintained within 48% to 50%, whichequates to a freeze point between -30°F(-34°C) and -34°F (-37°C).
Note:For best results, coolantconcentration should be tested with arefractometer such as Robinair® Coolantand Battery Refractometer 75240. We donot recommend the use of hydrometers orcoolant test strips for measuring coolantconcentrations.
Note:Automotive fluids are notinterchangeable. Do not use engine coolantor antifreeze or windshield washer fluidoutside of its specified function and vehiclelocation.
Adding Coolant
Note:Do not use stop leak pellets, coolingsystem sealants, or additives as they cancause damage to the cooling or heatingsystems. This damage would not be coveredunder your vehicle’s warranty.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
Note:It is very important to use coolantmeeting the Ford specification in order toavoid plugging the small coolantpassageways. Use of concentrated coolantand water may cause coolant passagewayplugging and void the warranty. SeeCapacities and Specifications (page 276).
•Do not mix different colors or types ofcoolant in your vehicle. Make sure thecorrect coolant is used. Mixing ofcoolants may harm your coolingsystem. The use of an improper coolantmay harm the engine, inverter systemcontroller, and cooling systemcomponents and may void thewarranty.
•In case of emergency, a large amountof water without engine coolant maybe added to the engine cooling systemin order to reach a vehicle servicelocation. In this instance, the enginecooling system must be drained,chemically cleaned with MotorcraftPremium Cooling System Flush, andrefilled with engine coolant as soon aspossible. Water alone (without enginecoolant) can cause engine damagefrom corrosion, overheating, or freezing.DO NOT use this method for theinverter system controller coolingsystem. The inverter system controllercooling system operates close toambient temperature, and issusceptible to freezing in anysubfreezing environment in theabsence of coolant.

CHANGING THE 12V BATTERY
WARNINGS
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.
Battery posts, terminals and relatedaccessories contain lead and leadcompounds. Wash hands afterhandling.
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 station

presets, 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 283). Reset the powerwindows bounce-back feature. SeeWindows and Mirrors (page 80).Reset the radio station presets. SeeAudio System (page 283).
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.

General Information
WARNING
Failure to follow these guidelinescould result in an increased risk ofloss of vehicle control, injury or death.
Note:Do not use the kit if you have severelydamaged a tire. Only seal punctures locatedwithin the tire tread with the kit.
Do not attempt to repair punctures largerthan ¼ inch (6 millimeters) or damage tothe tire's sidewall. The tire may notcompletely seal.
Loss of air pressure may adversely affecttire performance. For this reason:
Note:Do not drive the vehicle above50 mph (80 km/h).
Note:Do not drive further than 120 mi(200 km). Drive only to the closestauthorized Ford dealer or tire repair shop tohave your tire inspected.
•Drive carefully and avoid abruptsteering maneuvers.
•Periodically monitor tire inflationpressure in the affected tire; if the tireis losing pressure, have the vehicletowed.
•Read the information in the Tips forUse of the Kit section to make sure safeoperation of the kit and your vehicle.
Tips for Use of the Kit
To ensure safe operation of the kit:
•Read all instructions and cautions fully.
•Before operating the kit, make sureyour vehicle is safely off the road andaway from moving traffic. Switch onthe hazard lights.
•Always set the parking brake to makesure the vehicle does not moveunexpectedly.
•Do not remove any foreign objects,such as nails or screws, from the tire.
•When using the kit, leave the enginerunning (only if the vehicle is outdoorsor in a well-ventilated area) so thecompressor does not drain thevehicle's battery.
•Do not allow the compressor tooperate continuously for more than 15minutes. This will help prevent thecompressor from overheating.
•Never leave the kit unattended duringoperation.
•Sealant compound contains latex.Those with latex sensitivities shoulduse appropriate precautions to avoidan allergic reaction.
•Keep the kit away from children.
•Only use the kit when the ambienttemperature is between -22°F (-30°C)and 158°F (70°C).
•Only use the sealing compound beforethe use-by date. The use-by date is ona label on the sealant canister, whichyou can see through the rectangularviewing window on the bottom of thecompressor. Check the use-by dateregularly and replace the canister afterfour years of non-use.
•Do not store the kit unsecured insidethe passenger compartment of thevehicle as it may cause injury during asudden stop or crash. Always store thekit in its original location.
•After sealant use, an authorized Forddealer must replace the tire pressuremonitoring system sensor and valvestem on the wheel.
•Operating the kit could cause anelectrical disturbance in radio, CD andDVD player operation.

5. Remove the warning sticker found onthe canister and place it on the top ofthe instrument panel or the center ofthe dash.
6. Start the vehicle and leave the enginerunning so the compressor does notdrain the vehicle’s battery.
7. Turn dial (A) clockwise to the sealantposition. Switch the kit on by pressingthe on/off button (B).
8.Inflate the tire to the pressure listed onthe tire label located on the driver dooror the door jamb area. The initial airpressure gauge reading may indicatea value higher than the label pressurewhile you pump the sealing compoundinto the tire. This is normal and shouldbe no reason for concern. The pressure
gauge reading will indicate the tireinflation pressure after about 30seconds of operation. You shouldcheck the final tire pressure with thecompressor turned OFF in order to getan accurate pressure reading.
9. When the tire reaches therecommended tire pressure, switch offthe kit, unplug the power cable, anddisconnect the hose from the tire valve.Re-install the valve cap on the tirevalve and return the kit to the stowagearea.
10.Immediately and cautiously, drive thevehicle 4 miles (6 kilometers) todistribute the sealant evenly insidethe tire. Do not exceed 50 mph (80km/h).
