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 may beunder pressure. If you hear a hissing soundnear the fuel filler inlet, do not refuel untilthe sound stops. Otherwise, fuel may sprayout, which could cause serious personalinjury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Fuel may containbenzene, which is a cancer-causing agent.
WARNING: When refueling alwaysshut the engine off and never allow sparksor open flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
WARNING: Read and follow all theinstructions on the pump island.
Follow these guidelines when refueling:
•Extinguish all smoking materials and anyopen flames before refueling yourvehicle.
•Switch the engine off before refueling.
•Automotive fuels can be harmful or fatalif swallowed. Fuel is highly toxic and ifswallowed can cause death or permanentinjury. If fuel is swallowed immediatelycall a physician, even if no symptoms areimmediately apparent. The toxic effectsof fuel may not be apparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases, excessiveor prolonged breathing of fuel vapor cancause serious illness and permanentinjury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses, if worn, flush withwater for 15 minutes and seek medicalattention. Failure to seek proper medicalattention could lead to permanent injury.
•Fuels can be harmful if absorbed throughthe skin. If you splash fuel on your skin,clothing or both, promptly removecontaminated clothing and thoroughlywash your skin with soap and water.Repeated or prolonged skin contactcauses skin irritation.

FUEL QUALITY
SELECTING THE CORRECT FUEL
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87.
Some fuel stations, particularly those in highaltitude areas, offer fuels posted as regularunleaded gasoline with an octane ratingbelow 87. The use of these fuels could resultin engine damage that will not be coveredby 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 well asother conditions, for example when towinga trailer. See Towing a Trailer (page 349).
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.
We recommend Top Tier detergentgasolines, where available to help minimizeengine deposits and maintain optimal vehicleand 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.
•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, which is a manganese-based fueladditive, will impair engine performance andaffect the emission control system.
