ENGINE OIL CHECK
To check the engine oil level consistentlyand accurately, do the following:
1.Make sure the parking brake is on. Makesure the transmission is in park (P) orneutral (N).
2. Run the engine until it reaches normaloperating temperature.
3. Make sure that your vehicle is on levelground.
4.Switch the engine off and wait 15 minutesfor the oil to drain into the oil pan. Checking the engine oil level too soonafter you switch the engine off may resultin an inaccurate reading.
5. Open the hood. See Opening andClosing the Hood (page 361).
6. Remove the dipstick and wipe it with aclean, lint-free cloth. See Under HoodOverview (page 362).
7.Replace the dipstick and remove it againto check the oil level. See Engine OilDipstick (page 364).
8. Make sure that the oil level is betweenthe maximum and minimum marks. If theoil level is at the minimum mark, add oilimmediately. See Capacities andSpecifications (page 426).

If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of the coolantand may cause engine damage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.
Coolant Change
At specific mileage intervals, as listed in thescheduled maintenance information, thecoolant should be changed. Add predilutedcoolant approved to the correct specification.See Capacities and Specifications (page422).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambient temperature,vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates and amessage may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternating cylinderoperation. Each disabled cylinder acts as anair pump and cools the engine.
When this occurs, your vehicle still operates,however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, you canre-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is for useduring emergencies only. Operate yourvehicle in fail-safe mode only as long asnecessary to bring your vehicle to rest ina safe location and seek immediate repairs.When in fail-safe mode, your vehicle willhave limited power, will not be able tomaintain high-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the coolingsystem is hot. Wait 10 minutes for thecooling system to cool down. Cover thecoolant reservoir cap with a thick cloth toprevent the possibility of scalding andslowly remove the cap. Failure to followthis instruction could result in personalinjury.

Maintenance

Your vehicle has limited engine power whenin the fail-safe mode, drive your vehicle withcaution. Your vehicle does not maintainhigh-speed operation and the engine mayoperate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.
2. If you are a member of a roadsideassistance program, we recommend thatyou contact your roadside assistanceservice provider.
3.If this is not possible, wait a short periodfor the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and the vehiclemay not be able to accelerate with fullpower until the coolant temperaturereduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a long orsteep grade in high ambient temperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehicle speedcaused by reduced engine power in orderto manage the engine coolant temperature. Your vehicle may enter this mode if certainhigh-temperature and high-load conditionstake place. The amount of speed reductiondepends on vehicle loading, grade andambient temperature. If this occurs, there isno need to stop your vehicle. You cancontinue to drive.
The air conditioning may automatically turnon and off during severe operatingconditions to protect the engine fromoverheating. When the coolant temperaturedecreases to the normal operatingtemperature, the air conditioning turns on.
If the coolant temperature gauge moves fullyinto the red zone, or if the coolanttemperature warning or service engine soonmessages appear in your information display,do the following:
1.Stop your vehicle as soon as it is safe todo so. Fully apply the parking brake, shiftinto park (P) or neutral (N).

1. Clean the area around the filler plug.
2. Remove the filler plug.
3. Inspect the fluid level. The fluid levelshould be within 0.20 in (5 mm) from thebottom of the hole.
4. Add fluid through the filler opening. Fillto the bottom of the opening.
Use only fluid that meets our specifications.See Capacities and Specifications (page422).
BRAKE FLUID CHECK
WARNING: Do not use any fluid otherthan the recommended brake fluid as thiswill reduce brake efficiency. Use ofincorrect fluid could result in the loss ofvehicle control, serious personal injury ordeath.
WARNING: Only use brake fluid froma sealed container. Contamination with dirt,water, petroleum products or othermaterials may result in brake systemdamage or failure. Failure to adhere to thiswarning could result in the loss of vehiclecontrol, serious personal injury or death.
WARNING: Do not allow the fluid totouch your skin or eyes. If this happens,rinse the affected areas immediately withplenty of water and contact your physician.
WARNING: A fluid level between theMAX and MIN lines is within the normaloperating range and there is no need toadd fluid. A fluid level not in the normaloperating range could compromise theperformance of the system. Have yourvehicle checked immediately.
To avoid fluid contamination, the reservoircap must remain in place and fully tight,unless you are adding fluid.
Only use fluid that meets Ford specifications.See Capacities and Specifications (page422).
