2. Insert the fuel pump nozzle up to thefirst notch on the nozzle A. Keep itresting on the cover of the fuel tankfiller pipe opening.
3.Hold the fuel pump nozzle in the lowerposition B when refueling. Holding thefuel pump nozzle in the higher positionA may affect the flow of fuel and shutoff the fuel pump nozzle before the fueltank is full.
4.Slightly raise the fuel pump nozzle andthen slowly remove it.
5. Replace the fuel tank filler cap andclose the fuel tank filler door.
Note: Do not attempt to start the engineif you have filled the fuel tank with incorrectfuel. Incorrect fuel use can cause damagenot covered by the vehicle Warranty. Haveyour vehicle checked immediately.
Dual Fuel Tanks (If Equipped)
Your vehicle may have a dual fuel tankdelivery system which operatesindependently and automatically. The fuelpump in the front fuel tank delivers fuel tothe engine. When the fuel level in the frontfuel tank drops below three quarter full,fuel automatically transfers from the rearfuel tank to the front fuel tank. Wheneverthere is fuel in the rear fuel tank, the frontfuel tank level remains between half andthree quarter full.
Note:If your vehicle runs out of fuel, youmust add fuel to the front fuel tank torestart the engine.
FUEL CONSUMPTION
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included inthe advertised capacity is an emptyreserve. The empty reserve is anunspecified amount of fuel that remainsin the fuel tank when the fuel gaugeindicates empty.

Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
Filling the Fuel Tank
For consistent results when refueling:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate(low-medium-high) each time the tankis filled.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1,000 mi (1,600 km) of driving (this isyour engine’s break-in period). A moreaccurate measurement is obtained after2,000 mi (3,200 km) to 3,000 mi(4,800 km). Also, fuel expense, frequencyof fill ups or fuel gauge readings are notaccurate ways to measure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2. Each time you fill the fuel tank, recordthe amount of fuel added.
3. After at least three fill ups, fill the fueltank and record the current odometerreading.
4. Subtract your initial odometer readingfrom the current odometer reading.
To calculate L/100 km (liters per 100kilometers) fuel consumption, multiply theliters used by 100, then divide by kilometerstraveled. To calculate MPG (miles pergallon) fuel consumption, divide milestraveled by gallons used.
Keep a record for at least one month andrecord the type of driving (city or highway).This provides an accurate estimate of yourvehicle's fuel economy under currentdriving conditions. Keeping records duringsummer and winter will show howtemperature impacts fuel economy.
Conditions
•Heavily loading your vehicle reducesfuel economy.
•Carrying unnecessary weight in yourvehicle may reduce fuel economy.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You will get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.
EMISSION CONTROL SYSTEM
- GASOLINE
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.

Resonator and Tailpipe AssemblyMaintenance
Aftermarket devices or modifications tothe exhaust system may reduce theeffectiveness of the exhaust system aswell as cause damage to the exhaustsystem or engine. This may also degradevehicle performance and could lead toengine damage that may not be coveredby the vehicle Warranty.
Emission Control System Laws
WARNING
Do not remove or alter the originalequipment floor covering orinsulation between it and the metalfloor of the vehicle. The floor covering andinsulation protect occupants of the vehiclefrom the engine and exhaust system heatand noise. On vehicles with no originalequipment floor covering insulation, do notcarry passengers in a manner that permitsprolonged skin contact with the metalfloor. Failure to follow these instructionsmay result in fire or personal injury.
In the United States, federal law andcertain state laws prohibit removing orrendering the emission control systeminoperative. Similar federal or provinciallaws may apply in Canada. We do notrecommend any vehicle modificationwithout determining applicable law.
Tampering with emissionscontrol system, including relatedsensors or the diesel exhaustfluid injection system can result in reducedengine power and the service engine soonwarning lamp illuminating in theinformation display.
Tampering with a Noise ControlSystem
Federal law prohibits the following acts orthe causing thereof:
•The removal or rendering inoperativeby any person other than for purposesof maintenance, repair or replacementof any device or element of designincorporated into any new vehicle forthe purpose of noise control prior to itssale or delivery to the ultimatepurchaser or while it is in use.
•The use of the vehicle after such deviceor element of design has been removedor rendered inoperative by any person.
Among those acts, which the United StatesEnvironmental Protection Agency maypresume to constitute tampering are theacts listed below:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturer’sspecifications.
The complexity of the diesel engine makesit so the owner is discouraged fromattempting to perform maintenance otherthan the services described in this Owner'sManual.
If you experience difficulty starting theengine, rough idling, excessive exhaustsmoke, a decrease in engine performanceor excess fuel consumption, perform thefollowing checks:
•A plugged or disconnected air inletsystem or engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.

9. If the oil level is correct, replace thedipstick and make sure it is fully seated.
Note:Do not remove the dipstick when theengine is running.
Note:If the oil level is between themaximum and minimum marks, the oil levelis acceptable. Do not add oil.
Note:The oil consumption of new enginesreaches its normal level after approximately3,000 mi (5,000 km).
Adding Engine Oil
WARNING
Do not remove the filler cap whenthe engine is running.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that maynot be covered by the vehicle Warranty.
Only use oils certified for diesel engines bythe American Petroleum Institute (API).An oil with this trademark symbolconforms to the current engine andemission system protection standards andfuel economy requirements of theInternational Lubricants SpecificationAdvisory Committee (ILSAC), comprisedof U.S. and Japanese automobilemanufacturers.
To top up the engine oil level do thefollowing:
1. Clean the area surrounding the engineoil filler cap before you remove it.
2. Remove the engine oil filler cap. SeeUnder Hood Overview (page 323).Turn it counterclockwise and removeit.
3. Add engine oil that meets Fordspecifications. See Capacities andSpecifications (page 427). You mayhave to use a funnel to pour the engineoil into the opening.
4. Recheck the oil level.
5. If the oil level is correct, replace thedipstick and make sure it is fully seated.
6. Replace the engine oil filler cap. Turnit clockwise until you feel a strongresistance.
Note:Do not add oil further than themaximum mark. Oil levels above themaximum mark may cause engine damage.
Note:Make sure you install the oil filler capcorrectly.
Note:Soak up any spillage with anabsorbent cloth immediately.

Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Theinformation display may display a messageto change coolant at this time. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 415).
Engine-driven Cooling Fan (FanClutch)
Your vehicle may have an engine drivencooling fan drive (also called a fan clutch).This fan drive changes the fan speed tomatch the vehicle’s changing cooling airflow requirements. Fan speed, fan noiselevel and fuel consumption all will increasebased on the driving conditions thatinclude trailer towing, hill climbing, heavyloads, high speed and high ambienttemperature, individually or in combination.
The fan drive is designed to provide theminimum fan speed (and resultingminimum fan noise and fuel consumption)required to meet the ever changing vehiclecooling air flow requirements. You will hearthe amount of fan noise increasing anddecreasing as the engine powerrequirements and vehicle driving conditionschange as you drive. This is to be expectedas being normal to the operation of yourvehicle. High levels of fan noise might alsobe heard when your engine is first started,and should normally decrease after drivingfor a short time.
AUTOMATIC TRANSMISSION
FLUID CHECK
Have an authorized dealer check andchange the transmission fluid and filter atthe correct service interval. SeeScheduled Maintenance (page 573).
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
Checking Automatic TransmissionFluid
For scheduled intervals of the fluid checksand changes, See ScheduledMaintenance (page 573). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,i.e., if the transmission slips or shifts slowlyor if you notice some sign of fluid leakage.
Automatic transmission fluid expandswhen warmed. To obtain an accurate fluidcheck, drive the vehicle until it is at normaloperating temperature (approximately19 mi (30 km)). Verify that thetransmission fluid temperature gauge,located on the instrument cluster, is withinnormal range.
1. Drive the vehicle 19 mi (30 km)until itreaches normal operating temperature.
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 and leavethe engine running.
5. Remove the dipstick, wiping it cleanwith a clean, dry lint free rag. Ifnecessary, refer to the Under HoodOverview in this chapter for thelocation of the dipstick.
