Fuel Filler Cap (Gas Cap)

~2min read

The gas cap is located behind the fuel filler door, on the driver’s side of the vehicle. If the gas cap is lost or damaged, be sure the replacement cap has been designed for use with this vehicle.

• A poorly fitting gas cap may cause the MIL to turn on.

• 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 one quarter 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.
