To fill the fuel tank properly: NOTE: Extinguish all lit cigarettes, other smoking materials, and any open flames before fueling your vehicle. 1. Remove the fuel cap by following the instructions above under Removing the Fuel Cap in this chapter. Proceed to add fuel to the tank only if your vehicle is on level ground. Make sure that you pump unleaded fuel and put the nozzle all the way inside the fuel filler pipe. If you spill any fuel on the body of your vehicle, clean it off immediately. The fuel may dull or soften the paint if you do not wash it off. Replace the fuel cap completely when you are finished. Turn it clockwise until it is fully tight. It will click when it is fully tightened. 2. 3. 4. You may occasionally hear and/or feel a slight thump occurring one or two seconds after a gentle stop. This is normal and generally occurs with the fuel tank 3/4 full. It is caused by the wave action of the fuel within the tank. Running Out of Fuel If your vehicle runs out of fuel, try to stop on level ground away from traffic. Add at least two gallons (8 liters) of fuel to start your vehicle again. If your vehicle is not on level ground, you may need as much as five gallons (20 liters) of fuel to start it. NOTE: Avoid running out of fuel because this situation may have an adverse effect on modern powertrain components. 267
