Gasoline (cont'd) Fuel Filler Door and Cap Gasoline is extremely flammable and is explosive under certain conditions. Perform this operation in a well-ventilated area with the engine stopped. Do not smoke or allow open flames or sparks in the area or where gasoline is stored. The fuel filler door is opened by pulling up on the lever at the left side of the driver's seat. The door will lock automatically when closed; push it until it clicks. CAUTION: You may hear a hiss when you open the filler cap. This sound is residual pressure escaping from the fuel tank. Open the cap slowly and remove the cap after the hissing stops. Fuel spray may cause injury. Do not overfill the tank; fill only until the gas pump clicks off automatically and never top off. NOTE: The filter cap is a screw-in ratchetting type. Tighten the cap clockwise until ratchetting clicks are heard. Close Open The removed filler cap can be placed on the inside of the door. Fuel vapor is extremely hazardous under certain conditions. Always stop the engine before refueling, and never refuel near sparks or open flames. CAUTION: If you replace the cap, use only a genuine Honda replacement part or its equivalent. Failure to use the proper part could cause serious fuel system problems.
