• To avoid fuel spillage and overfilling, do not “top off” the fuel tank after filling.

• Never add fuel when the engine is running. This is in violation of most state and federal fire regulations and may cause the MIL to turn on.

• A fire may result if gasoline is pumped into a portable container that is inside of a vehicle. You could be burned. Always place gas containers on the ground while filling.

• Tighten the gas cap about 1/4 turn until you hear one click. This is an indication that the cap is properly tightened.

• If the gas cap is not tightened properly, the MIL will come on. Be sure the gas cap is tightened every time the vehicle is refueled.
