  • In certain cold conditions, ice may prevent the fuel door from opening. If this occurs, lightly push on the fuel door to break the ice buildup and re-release the fuel door using the inside release button. Do not pry on the door.
  • When the fuel nozzle "clicks" or shuts off, the fuel tank is full.
  • Tighten the gas cap about one quarter turn until you hear one click. This is an indication that the cap is properly tightened.

  • Damage to the fuel system or emission control system could result from using an improper fuel filler cap. A poorly fitting cap could let impurities into the fuel system. Also, a poorly fitting aftermarket cap can cause the "Malfunction Indicator Light (MIL)" to illuminate, due to fuel vapors escaping from the system.
  • A poorly fitting fuel filler cap may cause the MIL to turn on.
  • To avoid fuel spillage and overfilling, do not "top off" the fuel tank after filling.


  • Never have any smoking materials lit in or near the vehicle when the gas cap is removed or the tank is being filled.
  • 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.
