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 inlet, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Fuels can cause serious injury ordeath if misused or mishandled.
Fuel may contain benzene, which isa cancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Follow these guidelines when refueling:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Always switch the engine off beforerefueling.
•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 - GASOLINE
Choosing the Right Fuel
Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
1292018 Focus (CDH) Canada/United States of America, JM5J 19A321 AA enUSA, Edition date: 201706, Second PrintingFuel and RefuelingE161513
Page 133 of 473

Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. We do not recommendthese fuels.
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 182).
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.
Do not use any fuel other than thoserecommended because they could lead toengine damage that will not be covered bythe vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
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 (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
We recommend Top Tier detergentgasolines to help minimize engine depositsand maintain optimal vehicle and engineperformance. For additional information,refer to www.toptiergas.com.
FUEL FILLER FUNNEL
LOCATION
The fuel filler funnel is in the glovecompartment.
RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuelto restart the engine.
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal.
Note:If your vehicle is on a steep slope,more fuel may be required.
Filling a Portable Fuel Container
WARNING
Flow of fuel through a fuel pumpnozzle can produce static electricity.This can cause a fire if you are fillingan ungrounded fuel container.
