Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in highaltitude areas, offer fuels posted as regularunleaded gasoline with an octane ratingbelow 87. We do not recommend these 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.
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-based additives,including manganese-based compounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienyl manganesetricarbonyl (commonly known as MMT), whichis a manganese-based fuel additive, willimpair engine performance and affect theemission control system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contact anauthorized dealer to prevent any enginedamage.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functionaland the fuel fresh.
If you mainly use your vehicle in electricpower mode without refueling, the gasolinein the fuel tank may become stale due toaging. Stale gasoline can damage theengine and fuel system.
Your vehicle automatically switches to fuelfreshness mode if you do not refuel yourvehicle with fresh fuel within an 18-monthperiod. Fuel freshness mode protects yourvehicle from potential engine and fuel systemdamage caused by using stale fuel.
Note:If you do not add new fuel during an18-month period, fuel freshness mode willuse fuel until approximately 1.2 gal (4.5 L) offuel remains in the fuel tank.
During fuel freshness mode:
•The information display will indicate fuelfreshness mode is active.
•The vehicle will only run in hybrid mode.EV Now mode will not be available.
•Most of the plug-in power will be storeduntil fuel freshness mode is completed.
Note:EV Now mode resumes when less than1.2 gal (4.5 L) of fuel remains in the fuel tank.

Fuel and Refueling
If you use oil and fluids that do not meet thedefined specification and viscosity grade,this may lead to:
•Component damage which is notcovered by the vehicle warranty.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced engine performance.
•Reduced fuel economy.
•Degraded brake performance.
We recommend Motorcraft® motor oil foryour vehicle. If Motorcraft® oil is notavailable, use motor oils of therecommended viscosity grade that meet APISN requirements and display the APICertification Mark for gasoline engines. Donot use oil labeled with API SN servicecategory unless the label also displays theAPI certification mark.
An oil that displays this symbol conforms tocurrent engine, emission system and fueleconomy performance standards of ILSAC.
Do not use supplemental engine oil additivesbecause they are unnecessary and couldlead to engine damage that may not becovered by your vehicle warranty.
Note:Ford recommends using DOT 4 LowViscosity (LV) High Performance Brake Fluidor equivalent meeting WSS-M6C65-A2. Useof any fluid other than the recommendedfluid may cause degraded brakeperformance and not meet the Fordperformance standards. Keep brake fluidclean and dry. Contamination with dirt,water, petroleum products or other materialsmay result in brake system damage andpossible failure.
Note: Automatic transmissions that requireMERCON® LV transmission fluid should onlyuse MERCON® LV transmission fluid. Theuse of any other fluid may causetransmission damage.
Alternative Engine Oil for ExtremelyCold Climates
To improve engine cold start performance,we recommend that you use the followingalternative engine oil in extremely coldclimates, where the ambient temperaturereaches -22.0°F (-30°C) or below.
