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 of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may not be ableto accelerate with 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 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).

WARNING
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials may affecttransmission operation and result in damageto internal transmission components.
The transmission does not consume fluid.However, if the transmission slips or shiftsslowly you should check the fluid level. If younotice a sign of leaking fluid, contact anauthorized dealer.
Checking the Transmission Fluid Level*
Only check the transmission fluid level whenthe engine is at normal operating temprature179°F (82°C)-199°F (93°C). Normal operatingtemprature is reached after drivingapproximately 20 mi (30 km).

MaximumB
Note:Check the fluid level with the enginerunning and the transmission in park (P).
1. Make sure that your vehicle is on levelground.
2. Rotate the automatic transmission fluidcap in a counterclockwise direction. SeeUnder Hood Overview (page 310).
3. Remove the cap and dipstick and wipeit with a clean, lint-free cloth. Replace thecap and dipstick and remove it again tocheck the fluid level.
4.Make sure that the fluid level is betweenthe MIN and the MAX marks. If the fluidlevel is at the MIN mark, add fluidimmediately. See Adding TransmissionFluid.
5.Replace the automatic transmission fluidcap and dipstick. Turn it clockwise untilyou feel a strong resistance.
Low Fluid Level
If the fluid level is within the minimum range(below point A) add the correct specificationfluid to be within the hash mark area. SeeCapacities and Specifications (page 381).

Note:If your vehicle has a battery cover,after cleaning or replacing the battery, makesure you reinstall it.
Note:See an authorized dealer for batteryaccess, testing, or replacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connection directlyto the battery negative post. This can causeinaccurate measurements of the batterycondition and potential incorrect systemoperation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect battery performance and durability.This may also affect the performance ofother electrical systems in the vehicle.
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.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings are maintainedby power from the battery. Some enginecomputer settings, like the idle trim and fueltrim strategy, optimize the driveability andperformance of the engine. The clock andradio station presets are also maintained inmemory by power from the low-voltagebattery. These settings are erased when atechnician disconnects and connects thelow-voltage battery.
To restore the settings, do the following:
Note:Until you switch the ignition to the onposition, you will receive a message in yourinformation display stating that your vehicleis not in park.
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While the engineis warming up, complete the following:Reset the clock. See Audio Unit (page402). Reset the power windowsbounce-back feature. See PowerWindows (page 104). Reset the radiostation presets. See Audio Unit (page402).
6. Allow the engine to idle for at least oneminute.
7.Drive the vehicle at least 10 mi (16 km) tocompletely relearn the idle trim 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 fuel trimstrategy.
Note:Certain features may not operate ifthe battery monitor system is not reset witha scan tool following a jump start or batteryreplacement. Normal electrical accessoryoperation should resume after your vehicleis left undisturbed for 8 hours.

2. Carefully lift the air filter housing cover.
3.Remove the air filter element from the airfilter housing.
4. Wipe any dirt or debris from the air filterhousing and cover to make sure no dirtgets in the engine and to make sure youhave a good seal.
5.Install a new air filter element. Be carefulnot to crimp the filter element edgesbetween the air filter housing and cover.This could cause filter damage and allowunfiltered air to enter the engine if notproperly seated.
6. Install the air filter housing cover.
7.Engage the clamps to secure the air filterhousing cover to the air filter housing.

Vehicle Care

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 cold waterto avoid cracking the engine block orother engine components.
•Spray Motorcraft Engine Shampoo andDegreaser on all parts that requirecleaning and pressure rinse clean. InCanada, use Motorcraft Engine Shampoo.

•Never wash or rinse any ignition coil,spark plug wire or spark plug well, or thearea in and around these locations.
•Cover the battery, power distribution box,and air filter assembly to prevent waterdamage when cleaning the engine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmentalfallout can result in windshield and wiperblade contamination. Dirty windshield andwipers will result in poor windshield wiperoperation. Keep the windshield and wiperblades clean to maintain windshield wiperperformance.
To clean the windshield and wiper blades:
•Clean the windshield with a non-abrasiveglass cleaner. When cleaning the interiorof the windshield, avoid getting any glasscleaner on the instrument panel or doorpanels. Wipe any glass cleaner off thesesurfaces immediately.
•For windshields contaminated with treesap, chemicals, wax or bugs, clean theentire windshield using steel wool (nogreater than 0000 grade) in a circularmotion and rinse with water.
•Clean the wiper blades with isopropylrubbing alcohol or windshield washerconcentrate.
Note: Do not use razor blades or othersharp objects to clean or remove decals fromthe inside of the heated rear window. Thevehicle warranty does not cover damagecaused to the heated rear window grid lines.
CLEANING THE INTERIOR
