FUEL QUALITY
Note:Use of any fuel other than thoserecommended may cause powertraindamage, a loss of vehicle performance, andrepairs may not be covered under warranty.
Choosing the Right Fuel
Use only UNLEADED gasoline orUNLEADED gasoline blended with amaximum of 15% ethanol in your gasolinevehicle. If your vehicle is a Flex Fuel Vehicle(FFV), it will have a yellow bezel placedover the fuel fill inlet.
Do not use:
•fuels containing more than 15%ethanol or E-85 fuel
•fuels containing methanol
•fuels containing metallic basedadditives, including manganese-basedcompounds
•fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT)
•leaded-fuel (The use of leaded fuel isprohibited by law)
Note:Use of any fuel other than therecommended fuel can cause powertraindamage, impair the emission control systemor cause loss of vehicle performance. Anydamage to the vehicle that is caused by theuse of fuel not recommended will not becovered under warranty.
Octane Recommendations
Regular unleaded gasoline with a pump(R+M)/2 octane rating of 87 isrecommended. Some stations offer fuelsposted as Regular with an octane ratingbelow 87, particularly in high altitude areas.Fuels with octane levels below 87 are notrecommended.
Do not be concerned if your enginesometimes knocks lightly. However, if itknocks heavily under most drivingconditions while you are using fuel with therecommended octane rating, see yourauthorized dealer to prevent any enginedamage.
RUNNING OUT OF FUEL
Avoid running out of fuel because thissituation may have an adverse effect onpowertrain components.
If you have run out of fuel:
•You may need to cycle the ignition fromoff to on several times after refuelingto allow the fuel system to pump thefuel from the tank to the engine. Onrestarting, cranking time will take a fewseconds longer than normal. Withkeyless ignition, just start the engine.Crank time will be longer than usual.
•Normally, adding 1 gallon (3.8 liters) offuel is enough to restart the engine. Ifthe vehicle is out of fuel and on a steepgrade, more than 1 gallon (3.8 liters)may be required.
•The service engine soon indicator maycome on. For more information on theservice engine soon indicator, SeeWarning Lamps and Indicators(page 13).

5.To install the cap, align the tabs on thecap with the notches on the filler pipe.
6.Turn the filler cap clockwise 1/4 of aturn clockwise until it clicks at leastonce.
If the Check Fuel Cap light or a Check FuelCap message appears in the instrumentcluster and stays on after you start theengine, you may not have installed the fuelfiller properly.
If the fuel cap light remains on, at the nextopportunity, safely pull off of the road,remove the fuel filler cap, align the capproperly and reinstall it. The check fuel caplight or Check fuel cap message may notreset immediately. It may take severaldriving cycles for the indicators to turn off.A driving cycle consists of an enginestart-up (after four or more hours with theengine off) followed by normal city andhighway driving.
FUEL CONSUMPTION
Empty reserve is the amount of fuelremaining in the tank after the fuel gaugeindicates empty. The amount of usablefuel in the empty reserve varies and shouldnot be relied upon to increase driving range.
•The usable capacity of the fuel tank isthe amount of fuel that can be addedinto the tank after the gauge indicatesempty
•The advertised capacity is the total fueltank size. See Capacities andSpecifications (page 110). It is thecombined usable capacity plus theempty reserve.
•Due to the empty reserve, you may notbe able to refuel the full amount of theadvertised capacity of the fuel tankeven when the fuel gauge reads empty.
Filling the Tank
For consistent results when filling the fueltank:
•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 two automaticclick-offs when filling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1000 miles (1600 kilometers) ofdriving (this is your engine’s break-inperiod); a more accurate measurement isobtained after 2000 miles - 3000 miles(3200 kilometers - 4800 kilometers). Also,fuel expense, frequency of fill ups or fuelgauge readings are not accurate ways tomeasure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2.Each time you fill the tank, record theamount of fuel added.
3.After at least 3 to 5 tank fill ups, fill thefuel tank and record the currentodometer reading.
4.Subtract your initial odometer readingfrom the current odometer reading.
5.Calculate fuel economy by dividingmiles traveled by gallons used (ForMetric: Multiply liters used by 100, thendivide by kilometers traveled).
25Motorhome (), enUSAFuel and Refueling

Keep a record for at least 1 month andrecord the type of driving (city or highway).This provides an accurate estimate of thevehicle’s fuel economy under currentdriving conditions. Additionally, keepingrecords during summer and winter showhow temperature impacts fuel economy.In general, lower temperatures mean lowerfuel economy.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Carrying unnecessary weight mayreduce fuel economy (approximately1 mpg [0.4 km/L] is lost for every 400pounds [180 kilograms] of weightcarried).
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars/light bars, running boards, skiracks) may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Close windows for high speed driving.
EMISSION CONTROL SYSTEM
WARNINGS
Do not park, idle, or drive your vehiclein dry grass or other dry ground cover.The emission system heats up theengine compartment and exhaust system,which can start a fire.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your dealer inspect yourvehicle immediately. Do not drive if yousmell exhaust fumes.
Your vehicle is equipped with variousemission control components and acatalytic converter that will enable yourvehicle to comply with applicable exhaustemission standards. To make sure that thecatalytic converter and other emissioncontrol components continue to workproperly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while yourvehicle is moving, especially at highspeeds.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use parts other than Ford, Motorcraftor Ford-authorized parts for maintenancereplacements, or for service ofcomponents affecting emission control,such non-Ford parts should be theequivalent to genuine Ford Motor Companyparts in performance and durability.

If the service engine soonindicator is on or the bulb doesnot work, you may need to havethe vehicle serviced. See On-BoardDiagnostics (OBD-II).
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, your vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that the vehicle is ready forI/M testing.
The OBD-II system monitors the emissioncontrol system during normal driving. Acomplete check may take several days. Ifthe vehicle is not ready for I/M testing, youmay need to perform the following drivingcycle consisting of mixed city and highwaydriving:
Drive on an expressway or highway for asteady 15 minutes, followed by 20 minutesof stop-and-go driving with at least four30-second idle periods.
Allow the vehicle to sit for at least eighthours without starting the engine. Then,start the engine and complete the abovedriving cycle. The engine must warm up toits normal operating temperature. Oncestarted, do not turn off the engine until theabove driving cycle is complete. If thevehicle is still not ready for I/M testing, youwill have to repeat the above driving cycle.

AUTOMATIC TRANSMISSION
WARNINGS
Always set the parking brake fullyand make sure the gearshift islatched in P (Park). Turn the ignitionto the off position and remove the keywhenever you leave your vehicle.
Do not apply the brake pedal andaccelerator pedal simultaneously.Applying both pedals simultaneouslyfor more than three seconds will limitengine rpm, which may result in difficultymaintaining speed in traffic and could leadto serious injury.
Understanding the Positions ofYour Automatic Transmission
This vehicle is equipped with an adaptivetransmission shift strategy. Adaptivetransmission shift strategy offers theoptimal transmission operation and shiftquality. When the vehicle’s battery hasbeen disconnected for any type of serviceor repair, the transmission will need torelearn the normal shift strategyparameters, much like having to reset yourradio stations when your vehicle batteryhas been disconnected. The adaptivetransmission shift strategy allows thetransmission to relearn these operatingparameters.
This learning process could take severaltransmission upshifts and downshifts;during this learning process, slightly firmershifts may occur. After this learningprocess, normal shift feel and shiftscheduling will resume.
Putting your vehicle in or out of gear:
1.Fully press down the brake pedal.
2.Move the gearshift lever into thedesired gear.
3.Come to a complete stop.
4.Move the gearshift lever and securelylatch it in P (Park)
P (Park)
This position locks the transmission andprevents the rear wheels from turning.Come to a complete stop before puttingyour vehicle into and out of P (Park)
R (Reverse)
With the gearshift lever in R (Reverse), thevehicle will move backward. Always cometo a complete stop before shifting into andout of R (Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), thevehicle can be started and is free to roll.Hold the brake pedal down while in thisposition.
D (Overdrive) with tow/haul off
D (Overdrive) with tow/haul off is thenormal driving position for the best fueleconomy. The overdrive function allowsautomatic upshifts and downshifts throughgears one through five.
29Motorhome (), enUSATransmissionE161511PRND321

1 (First)
•Provides maximum engine braking
•Allows upshifts by moving gearshiftlever
•The transmission will not downshiftinto 1 (First) at high speeds; it willdownshift to a lower gear and thenshift into 1 (First) when the vehiclereaches slower speeds.
Forced downshifts
•Allowed in D (Overdrive) with thetow/haul feature on or off
•Press the accelerator to the floor
•Allows transmission to select anappropriate gear
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until youverify that the brake lamps areworking.
If your brake lamps are not workingproperly or if you have disconnectedthe vehicle battery cables, thevehicle brake lamps and hazard flashersmay not properly warn traffic of a vehiclebreakdown or approaching danger, whichcan increase the risk of serious injury ordeath. To minimize the risk of serious injuryor death, be aware of your surroundings,use other hazard signaling devices ifavailable, and move the vehicle to a safelocation away from traffic as soon aspossible.
When doing this procedure, you willbe taking the vehicle out of parkwhich means the vehicle can rollfreely. To avoid unwanted vehiclemovement, always fully set the parkingbrake prior to doing this procedure. Usewheel chocks if appropriate.
WARNINGS
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. See your authorizeddealer.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents thegearshift lever from being moved from P(Park) unless the brake pedal is pressed.
If you cannot move the gearshift lever outof P (Park) position with the ignition in the4 (on) position and the brake pedalpressed, a malfunction may have occurred.It is possible that a fuse has blown or thevehicle’s brake lamps are not operatingproperly. Refer to Fuses and relays in theRoadside Emergencies chapter. If the fusesand brake lamps are working properly, andthe vehicle still will not shift out of (P)Park, see your authorized dealer for service.
In an emergency, to disable themalfunctioning brake-shift interlockfeature in order to shift the vehicle from P(Park) follow these steps:
1.Apply the parking brake. Turn key tothe lock position, and then remove thekey.
2.Disconnect the negative (black)battery cable from the battery.
3.Insert the key and turn to the offposition. Shift to N (Neutral).
4.Reconnect the negative (black) batterycable to the battery.
5.Start the vehicle.
Note:See your authorized dealer as soonas possible if this procedure is used.

GENERAL INFORMATION
Note:Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and shouldbe inspected by an authorized dealer. If thevehicle has continuous vibration or shudderin the steering wheel while braking, thevehicle should be inspected by anauthorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the AlloyWheels (page 87).
See the Instrument Clusterchapter for information on thebrake system warning light.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Turn the engine off, shift to positionP and apply the parking brake, and theninspect the accelerator pedal for anyinterferences. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Hydraulic brake booster system(Hydroboost or Hydromax)
The Hydroboost and Hydromax systemsreceive fluid pressure from the powersteering pump to provide power assistduring braking.
The Hydromax booster receives backuppressure from the reserve system electricpump whenever the fluid in the powersteering system is not flowing. When theengine is off, the pump will turn on if thebrake pedal is applied, or if the ignition isturned to the on position.
The sound of the pump operating may beheard by the driver, but this is a normalcharacteristic of the system.
The reserve system provides reducedbraking power, so the vehicle should beoperated under these conditions withcaution, and only to seek service repair andremove the vehicle from the roadway.
Note:For Hydromax-equipped vehiclesoperating under normal conditions, the noiseof the fluid flowing through the booster maybe heard whenever the brake is applied. Thiscondition is normal. Vehicle service is notrequired.
If braking performance or pedal responsebecomes very poor, even when the pedalis strongly pressed, it may indicate thepresence of air in the hydraulic system orleakage of fluid. Stop the vehicle safely assoon as possible and seek serviceimmediately.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note:When the system is operating, thebrake pedal will pulse and may travelfurther. Maintain pressure on the brakepedal. You may also hear a noise from thesystem. This is normal.
The anti-lock braking system will noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
33Motorhome (), enUSABrakesE144522

•You take corners too fast.
•The road surface is poor.
PARKING BRAKE
WARNING
Always set the parking brake fullyand make sure the transmissionselector lever is placed in position P.Failure to set the parking brake and engagepark could result in vehicle roll-away,property damage or bodily injury. Turn theignition to the lock position and removethe key whenever you leave your vehicle.
Apply the parking brake whenever yourvehicle is parked. Press the pedaldownward to set the parking brake.
The brake warning lamp in theinstrument cluster illuminateswhen the ignition is turned onuntil the parking brake is released.
The parking brake is not recommended tostop a moving vehicle. However, if thenormal brakes fail, the parking brake canbe used to stop your vehicle in anemergency. Since the parking brake appliesonly the transmission mounted parkingbrake assembly, the vehicle's stoppingdistance will increase greatly and thehandling of your vehicle will be adverselyaffected.
To release the parking brake:
1.Press your foot brake pedal firmly.
2.Pull the parking brake release lever.
