SERVICE AND APPEARANCE CARE Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. SUZUKI recommends that you buy gasolines that are advertised to help keep fuel injectors and intake valves clean. If your vehicle experiences problems due to dirty injectors or valves, try a different brand of gasoline. Gasoline containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to contribute to clean air. SUZUKI recommends that you use these gasolines. tadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. SUZUKI does not recommend the use of such gasolines. Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The malfunction indicator lamp may turn on. If this occurs, return to your SUZUKI dealer for service. Filling Your Tank WARNING Fuel vapor burns violently and a fuel fire can cause severe injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off your engine when you are refueling. Don't smoke if you're near fuel or are refueling your vehicle. Keep sparks, flames and smoking materials away from fuel. Don't leave the fuel pump unattended when refueling your vehicle - this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel. Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn't be covered by your warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you'll be driving. CAUTION Your vehicle was not designed for fuel that contains methanol. Don't use fuel containing methanol. It can corrode metal parts in your fuel system and also damage the plastic and rubber parts. That damage wouldn't be covered under your warranty. Some gasolines that are not reformulated for low emissions may contain an octaneenhancing additive called methylcyclopen- 5-2
