00 SIENNA(U) GASOLINES ADDITIVES CONTAINING DETERGENT GASOLINES CONTAINING MMT Some gasolines contain an octane−enhancing additive called MMT (methylcyclopentadienyl manganese tricarbonyl). Toyota does not recommend the use of gasolines that contain MMT. If fuels containing MMT are used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Toyota dealer for service. GASOLINES CONTAINING ALCOHOL If you use gasohol in your Toyota, be sure that it is unleaded, has an octane rating no lower than 87 and does not contain more than 10% ethanol. Gasohol is a mixture of gasoline and ethanol. Toyota does not recommend the use of gasolines containing methanol. If you use gasoline containing methanol, use only gasoline meeting the requirements above and also containing less than 5% methanol with cosolvents and corrosion inhibitors for methanol. GASOLINES QUALITY In a very few cases, you may experience driveability problems caused by the particular gasoline that you are using. If you continue to have unacceptable driveability, try changing gasoline brands. If that does not rectify your problem, then consult your Toyota dealer. Toyota recommends use of gasolines that contain detergent additives to avoid build−up of engine deposits. For further details, ask your Toyota dealer or a local gasoline retailer. IMPROVED GASOLINES The American Automobile Manufacturers Association (AAMA) has developed a specification of improved gasolines. The AAMA specification offers optimal fuel information for better vehicle performance and better protection of your engine. Toyota recommends the use of gasolines that meet the AAMA specification, if available, for improved driveability and emission control system. GASOLINES CONTAINING MTBE Gasolines that contain MTBE (Methyl Tertiary−Butyl Ether) are available in the market. If you use a gasoline mixed with MTBE, make certain that it does not contain more than 15% of MTBE. NOTICE z Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performance problems. z If driveability problems occur (poor hot starting, vaporizing, engine knock, etc.), discontinue the use. z Take care not to spill gasohol during refueling. Gasohol may cause paint damage. FUEL TANK CAPACITY 79 L (21 gal., 17.5 lmp. gal.) 185
