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.
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.
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.
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 fuelsystem damage 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)of fuel remains in the fuel tank.
During fuel freshness mode:
•The information display will indicatefuel freshness 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 bestored until fuel freshness mode iscompleted.
Note:EV Now mode resumes when lessthan 1.2 gal (4.5 L) of fuel remains in the fueltank.
Note:When the fuel level is less thanone-quarter full, refueling your vehicle willend fuel freshness mode.
Note:We recommend you use a fuelstabilizer if you use less than a full tank offuel during an 18-month period.

If you use oil and fluids that do not meetthe defined specification and viscositygrade, 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 meetAPI SN 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 conformsto current engine, emission system andfuel economy performance standards ofILSAC.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that maynot be covered by your vehicle warranty.
