²Be particularly careful if you are taking ªAntabuseº or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors
or skin contact could cause an adverse reaction. Consult a physician
immediately.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Vehicles certified to California emission standards (indicated on the
underhood Vehicle Emissions Control Information label) are designed to
operate on California reformulated gasolines. If California reformulated
gasoline is not available when you refuel, your vehicle can be operated
on non-California fuels. However, even though your engine will perform
adequately on other gasolines, the performance of the emission control
devices and systems may be adversely affected.
Repair of damage caused by using a fuel that your vehicle was not
designed for may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªPremiumº gasoline for optimum
performance with an (R+M)/
2 octane rating of 91 or higher.
Gasolines with lower octance ratings
can be used, but performance may
decrease. We do not recommend
gasolines labeled as ªPremiumº in
high altitude areas that are sold with octane ratings less than 91.
Do not be concerned if your vehicle sometimes knocks lightly. However,
if it knocks heavily under most driving conditions on fuel with the
recommended octane, see your dealer or a qualified service technician to
prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº gasoline.
ªPremiumº gasoline is not recommended (particularly in the United
