GENERAL INFORMATION
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you startthe engine. Failure to follow thisinstruction could result in personal injuryor death.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 378).
If you disconnect the battery, your vehiclemay exhibit some unusual drivingcharacteristics for approximately 6 mi(10 km) after you reconnect it. This isbecause the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation. Only use the accelerator pedalwhen you have difficulty starting theengine.
IGNITION SWITCH
0 (off) - The ignition is off.
Note: When you switch the ignition off andleave your vehicle, do not leave your key inthe ignition. This could cause your vehiclebattery to lose charge.

2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingStarting and Stopping the EngineE304650

Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87 orregular unleaded gasoline blended with amaximum of 85% ethanol (E85).
Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by the vehicle warranty.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather as wellas other conditions, for example whentowing a trailer. See Towing (page 283).
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimalvehicle and engine performance. Foradditional information, refer towww.toptiergas.com.
Note:Use of any fuel for which the vehiclewas not designed can impair the emissioncontrol system, cause loss of vehicleperformance, and cause damage to theengine which may not be covered by thevehicle Warranty.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuels containing more than 85%ethanol or E100 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel, using leaded fuel isprohibited by law.
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Switching Between E85 andGasoline
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.

EMISSION LAW
WARNING: Do not remove or alterthe original equipment floor covering orinsulation between it and the metal floorof the vehicle. The floor covering andinsulation protect occupants of thevehicle from the engine and exhaustsystem heat and noise. On vehicles withno original equipment floor coveringinsulation, do not carry passengers in amanner that permits prolonged skincontact with the metal floor. Failure tofollow these instructions may result infire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components.Similar federal or provincial laws mayapply in Canada. We do not approve of anyvehicle modification without firstdetermining applicable laws.
Tampering with emissionscontrol systems includingrelated sensors or the DieselExhaust Fluid system can result in reducedengine power and the illumination of theservice engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative byany person other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery tothe ultimate purchaser or while it is inuse.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•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 manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessiveexhaust smoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.
•Water in the fuel filter and waterseparator.
•A clogged fuel filter.
•Contaminated fuel.
•Air in the fuel system, due to looseconnections.
•An open or pinched sensor hose.
•Incorrect engine oil level.

•Incorrect fuel for climatic conditions.
•Incorrect engine oil viscosity forclimactic conditions.
Note:Some vehicles have a lifetime fuelfilter that is integrated with the fuel tank.Regular maintenance or replacement is notneeded.
Note:If these checks do not help youcorrect the concern, have your vehiclechecked as soon as possible.
Noise Emissions Warranty,Prohibited Tampering Acts andMaintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb(4,536 kg) Gross Vehicle Weight Rating(GVWR). The preceding statementsconcerning prohibited tampering acts andmaintenance, and the noise warrantyfound in the Warranty Guide, areapplicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 293).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine Ford Motor Company parts inperformance and durability.

2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingEngine Emission Control

Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehiclesare not permitted to intentionally removean emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 185).
4.Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
