To remove the fuel cap, turn it slowly to the left (counterclockwise). On some vehicles you may have to push in while turning the cap. While refueling, hang the fuel cap inside of the fuel door. {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. Do not top off or overfill the tank, and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Washing Your Vehicle on page 5-90. The tethered fuel cap is located behind a hinged fuel door on the driver's side of the vehicle. The fuel door release lever is located near the floor under the driver's seat on the outboard side. 5-8
