Maintenance and care 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 manganeseĆbased compounds containing (MMT). Vehicles certified to meet California emission standards (indicated on the underhood Vehicle Emission 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 nonĆCalifornia 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 for which your vehicle was not designed may not be covered by your warranty. 230
