{CAUTION: If you spill fuel and then something ignites it, you could be badly burned. Fuel can spray out on you if you open the fuel cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any "hiss" noise to stop. Then unscrew the cap all the way. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle on page 5-98 Cleaning the Outside of Your Vehicle. When filling the tank do not overfill by squeezing in much more fuel after the pump shuts off. When you put the fuel cap back on, turn it to the right (clockwise) until you hear a clicking sound. 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. If the fuel cap is not properly installed, FUEL CAP will appear on the DIC and the check engine light will be lit on instrument panel cluster. See DIC Warnings and Messages on page 3-39 and Malfunction Indicator Lamp on page 3-30 for more information. 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 on page 3-30. {CAUTION: If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately. Be careful not to spill fuel. Do not top off or overfill your tank and wait a few seconds after you have finished pumping before you remove the nozzle. 5-9
