  • Never smoke or light smoking materials near the vehicle while the fuel fill door is open or the tank is being filled.
  • Never add fuel with the engine running. This is a violation of most state and federal fire safety regulations and may cause the "Check Engine" light to illuminate.
  • A fire may occur if fuel is dispensed into a portable container located inside the vehicle. You may be burned. Always place fuel containers on the ground while refueling.

NOTE:

  • When the fuel nozzle clicks or shuts off, the fuel tank is full.
  • Tighten the fuel cap about one-quarter turn until you hear one click. This indicates that the cap is properly tightened.
  • If the fuel filler cap is not tightened properly, the MIL will illuminate. Make sure the cap is tightened each time you refuel the vehicle.
