Engine Oil Pressure Gauge
Indicates engine oil pressure. The needleshould stay in the normal operating range(between L and H). If the needle fallsbelow the normal range, stop the vehicle,turn off the engine and check the engineoil level. Add oil if needed. If the oil level iscorrect, have your vehicle checked by yourauthorized dealer.
Engine Coolant TemperatureGauge
WARNING
Never remove the coolant reservoircap while the engine is running or hot.
Indicates engine coolant temperature. Atnormal operating temperature, the levelindicator will be in the normal range. If theengine coolant temperature exceeds thenormal range, stop the vehicle as soon assafely possible, switch off the engine andlet the engine cool.
Transmission Fluid TemperatureGauge
Indicates transmission fluid temperature.At normal operating temperature, the levelindicator will be in the normal range. If thetransmission fluid temperature exceedsthe normal range, stop the vehicle as soonas safely possible and verify the airflow isnot restricted such as snow or debrisblocking airflow through the grill. Also,higher than normal operating temperaturecan be caused by special operationconditions (i.e. snowplowing, towing oroff-road use). Refer to Special operatingconditions in the scheduled maintenanceinformation for instructions. Operating the
transmission for extended periods of timewith the gauge in the higher than normalarea may cause internal transmissiondamage. Altering the severity of the drivingconditions is recommended to lower thetransmission temperature into the normalrange. If the gauge continues to show hightemperatures, see your authorized dealer.
Fuel Gauge
Note:The fuel gauge may vary slightlywhen your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge willindicate approximately how much fuel isleft in the fuel tank. The arrow adjacent tothe fuel pump symbol indicates on whichside of your vehicle the fuel filler door islocated.
The needle should move toward F whenyou refuel your vehicle. If the needle pointsto E after adding fuel, this indicates yourvehicle needs service soon.
After refueling some variability in needleposition is normal:
•It may take a short time for the needleto reach F after leaving the gas station.This is normal and depends upon theslope of pavement at the gas station.
•The fuel amount dispensed into thetank is a little less or more than thegauge indicated. This is normal anddepends upon the slope of pavementat the gas station.
•If the gas station nozzle shuts offbefore the tank is full, try a differentgas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the fuelgauge needle is at 1/16th.

Low Fuel Level
Illuminates when the fuel levelis low or the fuel tank is nearlyempty. Refuel as soon aspossible.
Low Tire Pressure Warning
Illuminates when your tirepressure is low. If the lampremains on with the enginerunning or when driving, checkyour tire pressure as soon as possible.
It will also illuminate momentarily whenyou switch the ignition on to confirm thelamp is functional. If it does not illuminatewhen you switch the ignition on, or beginsto flash at any time, have the systemchecked by your authorized dealer.
Powertrain Malfunction/ReducedPower/Electronic Throttle Control
Illuminates when a powertrainor an AWD fault has beendetected. Contact yourauthorized dealer as soon as possible.
Service Engine Soon
If the service engine soonindicator light stays illuminatedafter the engine is started, itindicates that the On-Board Diagnostics(OBD-II) system has detected amalfunction of the vehicle emissionscontrol system. Refer to On-BoardDiagnostics (OBD-II) in the Fuel andRefueling chapter for more informationabout having your vehicle serviced. SeeEmission Control System (page 141).
If the light is blinking, engine misfire isoccurring which could damage yourcatalytic converter. Drive in a moderatefashion (avoid heavy acceleration anddeceleration) and have your vehicleserviced immediately.
Note:Under engine misfire conditions,excessive exhaust temperatures coulddamage the catalytic converter or othervehicle components.
The service engine soon indicator lightilluminates when the ignition is first turnedon prior to engine start to check the bulband to indicate whether the vehicle is readyfor Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light willstay on until the engine is cranked, thenturn itself off if no malfunctions arepresent. However, if after 15 seconds theservice engine soon light blinks eight times,it means that the vehicle is not ready forI/M testing. See Emission ControlSystem (page 141).
Stability Control
Illuminates when the system isactive. If it remains illuminatedor does not illuminate when youswitch the ignition on, this indicates amalfunction. During a malfunction thesystem will switch off. Have the systemchecked by your authorized dealerimmediately. See Using StabilityControl (page 167).

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel sprayand fire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler door, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Automotive fuels can cause seriousinjury or death if you misuse ormishandle them.
Fuel ethanol and gasoline maycontain benzene, which is acancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the filler neck.Never smoke or use a cell phone whilerefueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
The flow of fuel through a fuel pumpnozzle can produce static electricity,which can cause a fire if you pumpfuel into an ungrounded fuel container.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If swallowed, call aphysician immediately, even if nosymptoms are immediately apparent.The toxic effects of fuel may not bevisible for hours.
•Avoid inhaling fuel vapors. Inhaling toomuch fuel vapor of any kind can leadto eye and respiratory tract irritation.In severe cases, excessive or prolongedbreathing of fuel vapor can causeserious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. Ifyou splash fuel in your eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.
•Fuels can also be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andwash your skin thoroughly with soapand water. Repeated or prolonged skincontact with fuel liquid or vapor causesskin irritation.
•Be particularly careful if you are taking“Antabuse” or other forms of disulfiramfor the treatment of alcoholism.Breathing gasoline vapors, or skincontact could cause an adversereaction. In sensitive individuals, seriouspersonal injury or sickness may result.If you splash fuel on your skin, promptlywash your skin thoroughly with soapand water. Consult a physicianimmediately if you experience anadverse reaction.
136Super Duty (), enUSAFuel and Refueling

We recommend regular unleaded gasolinewith a pump (R+M)/2 octane rating of 87.Some stations offer fuels posted as regularwith an octane rating below 87, particularlyin high altitude areas. We do notrecommend fuels with an octane ratingbelow 87.
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 77).
Refilling With a Portable FuelContainer
WARNINGS
The fuel system may be underpressure. If the fuel filler cap isventing vapor or if you hear a hissingsound, wait until it stops before completelyremoving the fuel filler cap. Otherwise, fuelmay spray out and cause personal injury.
Do not try to pry open or push openthe fuel system with foreign objects.This could damage the fuel systemand its seal and cause personal injury toyou or others.
Use the following directions when fillingfrom a portable fuel container:
1.Remove the fuel cap from the fuel fillerpipe by rotating it counter clockwise.
2.Slowly insert the portable fuelcontainer into the fuel filler opening.
3.Fill the vehicle with fuel from theportable fuel container.
4.4. When done, remove the portablefuel container nozzle and reinstall fuelcap. Insert fuel cap into fuel filleropening and turn clockwise until a clickis heard.

•Place approved fuel container on theground.
•Do not fill a fuel container while it is inthe vehicle (including the cargo area).
•Keep the fuel pump nozzle in contactwith the fuel container while filling.
•Do not use a device that would holdthe fuel pump handle in the fill position.
Fuel Filler Cap
WARNINGS
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler door, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
If you do not use the proper fuel fillercap, excessive pressure or vacuumin the fuel tank may damage the fuelsystem or cause the fuel cap to disengagein a collision, which may result in possiblepersonal injury.
Note:If you must replace the fuel filler cap,replace it with a fuel filler cap that isdesigned for your vehicle. The customerwarranty may be void for any damage to thefuel tank or fuel system if the correctgenuine Ford, Motorcraft® or other certifiedfuel filler cap is not used.
Your fuel tank filler cap has an indexeddesign with a 1/4th turn on and off feature.When fueling your vehicle:
