{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. Be careful not to spill fuel. Don't top off or overfill your tank, and wait a few seconds after you've 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 5-81. While refueling, hang the tethered cap inside the fuel door. To remove the fuel cap, turn it slowly to the left (counterclockwise). The fuel cap has a spring in it; if you let go of the cap too soon, it will spring back to the right. 5-9
