The system is designed to work in a waythat complements other vehicle systems,allowing them to operate at optimumperformance.
The system does not stop the engine if:
•The driver door is open.
•Your vehicle is at high altitude.
•The heated windshield is on.
•The engine is warming up.
•The outside temperature is too low ortoo high.
•The battery charge is low.
•The battery temperature is outside theoptimal operating range.
•The engine is required to run tomaintain interior climate and reducefogging.
Why does the engine sometimesrestart when I do not expect it to?
The system is designed to work in a waythat complements other vehicle systems,allowing them to operate at optimumperformance.
The system restarts the engine if:
•You switch the heated windshield on.
•You switch maximum defrost on.
•Your vehicle starts to roll downhill inneutral.
•The engine is required to run tomaintain adequate brake systemassistance.
•The engine is required to run tomaintain interior climate and reducefogging.
Can I permanently switch thesystem off?
No. The system plays an important role inreducing the fuel consumption and the CO2emissions.
Will the frequent engine startscause parts to wear out?
Your vehicle has an enhanced battery andstarter motor that are designed for theincreased number of engine starts.

FUEL AND REFUELING
PRECAUTIONS
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Fuel may containbenzene, which is a cancer-causingagent.
WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: Read and follow all theinstructions on the pump island.
Follow these guidelines when refueling:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Switch the engine off before refueling.
•Automotive fuels can be harmful orfatal if swallowed. Fuel is highly toxicand if swallowed can cause death orpermanent injury. If fuel is swallowedimmediately call a physician, even if nosymptoms are immediately apparent.The toxic effects of fuel may not beapparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases,excessive or prolonged breathing offuel vapor can cause serious illness andpermanent injury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses, if worn, flushwith water for 15 minutes and seekmedical attention. Failure to seekproper medical attention could lead topermanent injury.
•Fuels can be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andthoroughly wash your skin with soapand water. Repeated or prolonged skincontact causes skin irritation.
•Be particularly careful if you are takingAntabuse or other forms of Disulfiramfor the treatment of alcoholism.Breathing fuel vapors could cause anadverse reaction, serious personalinjury or sickness. Immediately call aphysician if you experience any adversereactions.

FUEL QUALITY
SELECTING THE CORRECT FUEL
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87.
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 a Trailer(page 307).
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.
For additional information, visitwww.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.
•Fuel containing more than 15% ethanolor E85 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, which is amanganese-based fuel additive, will impairengine performance and affect theemission control system.
LOCATING THE FUEL FILLER
FUNNEL
The fuel filler funnel is in the rear floorcompartment with the jack and tools.
180
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMFuel and RefuelingE161513

Note:If your vehicle runs out of fuel add aminimum of 1.3 gal (5 L) of fuel to restartthe engine.
Note:You may need to switch the ignitionfrom off to on several times after refuelingto allow the fuel system to pump the fuelfrom the tank to the engine. Whenrestarting, cranking time takes a fewseconds longer than normal.
Note:Extra funnels can be purchased froman authorized dealer if you choose todispose of the funnel.

WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
WARNING: Do not pry open thefuel tank filler valve. This could damagethe fuel system. Failure to follow thisinstruction could result in fire, personalinjury or death.
WARNING: Do not remove the fuelpump nozzle from its fully insertedposition when refueling.
WARNING: Stop refueling whenthe fuel pump nozzle automaticallyshuts off for the first time. Failure tofollow this will fill the expansion spacein the fuel tank and could lead to fueloverflowing.
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: Wait at least fiveseconds before removing the fuel pumpnozzle to allow any residual fuel to draininto the fuel tank.
1.Fully open the fuel filler door.
2.Select the correct fuel pump nozzle foryour vehicle.

3.Insert the fuel pump nozzle up to thefirst notch. Keep the fuel pump nozzleresting on the fuel tank filler pipe.
4.Hold the fuel pump nozzle in positionA when refueling. Holding the fuelpump nozzle in position B can affectthe flow of fuel and shut off the fuelpump nozzle before the fuel tank is full.
5.Operate the fuel pump nozzle withinthe area shown. Refer to A for left handdrive or B for right hand drive.
6.When the pump shuts off, wait fiveseconds, then raise the fuel pumpnozzle and slowly remove it.
7.Fully close the fuel filler door.
Note: Do not attempt to start the engineif you have filled the fuel tank with incorrectfuel. Incorrect fuel use could cause damagenot covered by the vehicle Warranty. Haveyour vehicle immediately checked.
