HYBRID ELECTRIC VEHICLEINFORMATION – FREQUENTLYASKED QUESTIONS
What should I do if the vehicle runs outof fuel and the high voltage battery isout of charge?
Refuel and start your vehicle normally.The engine will recharge the highvoltage battery.
Why does the engine sometimes startat key-on?
The vehicle's computer determines ifan engine start is required at key-on.It starts the engine when necessary forcabin heating, windshield defrost, or ifthe outside temperature is low.
Can I put E15 or E85 in my vehicle, andhow will it affect my fuel economy?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but youmay notice slightly reduced fueleconomy because ethanol containsless energy per gallon than gasoline.Your hybrid vehicle is not designed touse E85 (85% ethanol).
Why does it take a long time before theengine shuts down?
There are several reasons the enginestays on for an extended amount oftime when you first start it. Onecommon reason is to make sure thatthe emissions components are warmenough to minimize tailpipe emission.As the climate gets cooler, theengine-on time is extended.
Why does my engine stay on when it isextremely cold outside?
In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.

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.

FUEL QUALITY
SELECTING THE CORRECT FUEL -FLEX FUEL – ETHANOL
Flex fuel vehicles have one of the followingidentifiers:
•Yellow fuel filler cap.
•Yellow bezel around the fuel filler inlet.
•Yellow fuel filler housing.
•Yellow E85 label on the fuel tank fillerdoor.
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87 or regular unleadedgasoline blended with a maximum of 85%ethanol (E85).
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 418).
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.
•Fuels containing more than 85%ethanol or E100 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.

SWITCHING BETWEEN E85 ANDGASOLINE
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.
