2.If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3.If this is not possible, wait a shortperiod for 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,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine 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 thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
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 vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road, you can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. Afterseveral minutes, if the temperaturedoes not drop, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.

AUTOMATIC TRANSMISSION
FLUID CHECK
WARNING: The dipstick andsurrounding components are hot. Usegloves when moving components andchecking the transmission fluid level.Failure to follow this warning could resultin serious personal injury.
Note:Automatic transmission fluidexpands when warmed. To obtain anaccurate fluid check, drive the vehicle untilit is at normal operating temperature(approximately 20 mi (30 km)). If yourvehicle has been operated for an extendedperiod at high speeds, in city traffic duringhot weather or pulling a trailer, the vehicleshould be turned off for about 30 minutesto allow fluid to cool to normal operatingtemperature 196°F - 215°F (91°C - 102°C)before checking.
Refer to your scheduled maintenanceinformation for scheduled intervals for fluidchecks and changes.
Your transmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,(i.e., if the transmission slips or shiftsslowly) or if you notice some sign of fluidleakage. To check the fluid level:
1.Drive the vehicle 20 mi (30 km) or untilit reaches normal operatingtemperature
2.Park the vehicle on a level surface andengage the parking brake
3.With the engine running, parking brakeengaged and your foot on the brakepedal, move the gearshift lever throughall of the gear ranges. Allow sufficienttime for each gear to engage
4.Latch the gearshift lever in P (Park)and leave the engine running.
5.Remove the dipstick, wiping it cleanwith a clean, dry lint free rag. Ifnecessary, refer to Under HoodOverview in this chapter for thelocation of the dipstick.
6.Install the dipstick making sure it is fullyseated in the filler tube.
7.Remove the dipstick and inspect thefluid level. The fluid should be in thedesignated area for normal operatingtemperature or ambient temperature.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Low fluid level
Do not drive the vehicle if there is noindication of fluid on the dipstick and theambient temperature is above 50°F(10°C).
Correct fluid level

Add brake fluid from a clean unopenedcontainer until the level reaches MAX. Donot fill above this line. Use only DOT 3brake fluid that is certified to meet Fordspecifications.
Brake system fluid should be replaced ona regular basis to maintain optimumbraking performance, especially underheavy-duty driving conditions such asfrequent steep grades or heavy towingloads. See Scheduled Maintenance(page 145).
POWER STEERING FLUID
CHECK
Note:The power steering cap has both acold and hot indicator on the dipstick.
1.Start the engine and let it run until itreaches normal operating temperature(the engine coolant temperature gaugeindicator will be near the center of thenormal area between H and C).
2.While the engine idles, turn the steeringwheel left and right several times.
3.Turn the engine off.
4.Check the fluid level on the dipstick. Itshould be between the arrows in theFULL range on the side of the dipstickwith the words MAX. HOT at the top.Do not add fluid if the level is withinthis range.
5.If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it reaches the FULL range.Be sure to put the dipstick back in thereservoir.

•The transmission must relearn itsadaptive strategy. As a result of this,the transmission may shift firmly. Thisoperation is considered normal and willnot affect function or durability of thetransmission. Over time the adaptivelearning process will fully updatetransmission operation to its optimumshift feel.
•The clock and the preset radio stationsmust be reset once the battery isreconnected.
•Your vehicle’s engine is electronicallycontrolled by a computer, some controlconditions are maintained by powerfrom the battery, the engine mustrelearn its idle and fuel trim strategy.
When the battery is disconnected or a newbattery is installed, begin the batteryrelearn process:

Underbody
Regularly clean the underside of yourvehicle using water. Keep body and doordrain holes free of debris or foreignmaterial.
Under Hood
For removing black rubber marks fromunder the hood we recommend MotorcraftWheel and Tire Cleaner or Motorcraft Bugand Tar Remover.
CLEANING THE ENGINE
Engines are more efficient when they areclean because grease and dirt buildup keepthe engine warmer than normal.
When washing:
•Take care when using a power washerto clean the engine. The high-pressurefluid could penetrate the sealed partsand cause damage.
•Do not spray a hot engine with coldwater to avoid cracking the engineblock or other engine components.
•Spray Motorcraft Engine Shampoo andDegreaser on all parts that requirecleaning and pressure rinse clean. InCanada, use Motorcraft EngineShampoo.
Note:If your vehicle has an engine coverremove the cover before application ofMotorcraft Engine Shampoo and Degreaser.Immediately rinse away any over spray.
•Never wash or rinse the engine while itis hot or running; water in the runningengine may cause internal damage.
•Never wash or rinse any ignition coil,spark plug wire or spark plug well, orthe area in and around these locations.
•Cover the battery, power distributionbox, and air filter assembly to preventwater damage when cleaning theengine.
CLEANING THE WHEELS (IF
EQUIPPED)
1.Regularly clean them with a wheelcleaner. We recommend that you useFord approved wheel cleaner ifavailable.
2.Remove dirt and brake dust with asponge.
3.Remove tar and grease with a bug andtar remover. We recommend that youuse Ford approved bug and tar removerif available.
4.Thoroughly rinse the wheels with waterafter cleaning.
If you intend on parking your vehicle for anextended period after cleaning the wheelswith a wheel cleaner, drive your vehicle fora few minutes before doing so. Thisreduces the risk of corrosion of the brakediscs, brake pads and linings.
Do not clean the wheels when they are hot.
