AnswerQuestion
The engine is required to turn on above thisspeed to protect the transmission hard-ware.
Why does my engine never shut downabove 85 mph (137 km/h)
In order to make sure that the climatecontrol system can begin heating the cabinor defrosting the windshield as soon as adriver requests it, the engine coolanttemperature has to be kept sufficiently hot.Keeping the engine on is required to main-tain the correct coolant temperature.
Why does my engine stay on when it isextremely cold outside?
Your vehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. This maybe higher than expected during heavyaccelerations, and may fluctuate whendriving at a steady speed. These are charac-teristics of the Atkinson engine cycle andthe transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high some-times when I accelerate?
The fan noise comes from a fan locatednext to the high voltage battery pack. Thisfan turns on when the battery requirescooling air. The fan speed, and associatednoise level, will change according to theamount of cooling required to maintaingood performance. Maintaining the batterytemperature at optimal conditions alsoprolongs the useful life of the battery andhelps to achieve better fuel economy.
What is the fan noise I hear from the rearof my hybrid?
Change the engine oil every 10,000 mi(16,000 km) or once per year under normaloperating conditions.
What is the engine oil change serviceinterval?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but you maynotice slightly reduced fuel economybecause ethanol contains less energy pergallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and howwill it affect my fuel economy?

Unique Driving Characteristics

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.

Engine 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 160).
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.
