FUEL QUALITY
Note:Use of any fuel other than thoserecommended may cause powertraindamage, a loss of vehicle performance, andrepairs may not be covered under warranty.
Choosing the Right Fuel
Use only UNLEADED gasoline orUNLEADED gasoline blended with amaximum of 15% ethanol in your gasolinevehicle. If your vehicle is a Flex Fuel Vehicle(FFV), it will have a yellow bezel placedover the fuel fill inlet.
Do not use:
•fuels containing more than 15%ethanol or E-85 fuel
•fuels containing methanol
•fuels containing metallic basedadditives, including manganese-basedcompounds
•fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT)
•leaded-fuel (The use of leaded fuel isprohibited by law)
Note:Use of any fuel other than therecommended fuel can cause powertraindamage, impair the emission control systemor cause loss of vehicle performance. Anydamage to the vehicle that is caused by theuse of fuel not recommended will not becovered under warranty.
Octane Recommendations
Regular unleaded gasoline with a pump(R+M)/2 octane rating of 87 isrecommended. Some stations offer fuelsposted as Regular with an octane ratingbelow 87, particularly in high altitude areas.Fuels with octane levels below 87 are notrecommended.
Do not be concerned if your enginesometimes knocks lightly. However, if itknocks heavily under most drivingconditions while you are using fuel with therecommended octane rating, see yourauthorized dealer to prevent any enginedamage.
RUNNING OUT OF FUEL
Avoid running out of fuel because thissituation may have an adverse effect onpowertrain components.
If you have run out of fuel:
•You may need to cycle the ignition fromoff to on several times after refuelingto allow the fuel system to pump thefuel from the tank to the engine. Onrestarting, cranking time will take a fewseconds longer than normal. Withkeyless ignition, just start the engine.Crank time will be longer than usual.
•Normally, adding 1 gallon (3.8 liters) offuel is enough to restart the engine. Ifthe vehicle is out of fuel and on a steepgrade, more than 1 gallon (3.8 liters)may be required.
•The service engine soon indicator maycome on. For more information on theservice engine soon indicator, SeeWarning Lamps and Indicators(page 13).
