Maintenance and care Use the following guidelines to avoid static build-up when filling an ungrounded fuel container: • Place approved fuel container on the ground. • DO NOT fill a fuel container while it is in the vehicle (including the cargo area). • Keep the fuel pump nozzle in contact with the fuel container while filling. • DO NOT use a device that would hold the fuel pump handle in the fill position. Choosing the right fuel Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law and could damage your vehicle. If your vehicle is a flexible fuel vehicle (FFV), use only UNLEADED FUEL and ETHANOL(E85). The use of leaded fuel is prohibited by law and could damage your vehicle. Do not use fuel containing methanol. It can damage critical fuel system components. Your vehicle was not designed to use fuel or fuel additives with metallic compounds, including manganese-based compounds containing MMT. Repairs to correct the effects of using a fuel for which your vehicle was not designed may not be covered by your warranty. Octane recommendations Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily under most driving conditions while you are (R+M)/2 METHOD using fuel with the recommended octane rating, see your dealer or a qualified service technician to prevent any engine damage. Unleaded Gasoline engines Your vehicle is designed to use "Regular" unleaded gasoline with an (R+M)/2 octane rating of 87. We do not recommend the use of gasolines labeled as "Regular" that are sold with octane ratings of 86 or lower in high altitude areas. 87 211
