Maintenance and care WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS Important safety precautions Do not overfill the fuel tank. The pressure in an overfilled tank may cause leakage and lead to fuel spray and fire. The fuel system may be under pressure. If the fuel filler cap is venting vapor or if you hear a hissing sound, wait until it stops before completely removing the fuel filler cap. Otherwise, fuel may spray out and injure you or others. If you do not use the proper fuel filler cap, excessive pressure or vacuum in the fuel tank may damage the fuel system or cause the fuel cap to disengage in a collision, which may result in possible personal injury. Automotive fuels can cause serious injury or death if misused or mishandled. Gasoline may contain benzene, which is a cancer-causing agent. 199
