Be careful not to spill fuel. Don't top off or overfill your tank, and wait a few seconds after you have finished pumping before you remove the nozzle. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle on page 5-93. When you put the fuel cap back on, turn it to the right (clockwise) until you hear three "clicks." Make sure you fully install the cap. The diagnostic system can determine if the fuel cap has been left off or improperly installed. This would allow fuel to evaporate into the atmosphere. See Malfunction Indicator Lamp on page 3-40. {CAUTION: If a fire starts while you're refueling, don't remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. Notice: If you need a new fuel cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit properly. This may cause your malfunction indicator lamp to light and may damage your fuel tank and emissions system. See "Malfunction Indicator Lamp" in the Index. 5-9
