The fuel door release button is located on the left side of the instrument panel. The button only works when the vehicle is in PARK (P) or NEUTRAL (N) and the valet lockout button is in OFF. To remove the fuel cap, turn it slowly counterclockwise. The fuel cap has a spring in it; if the cap is released too soon, it will spring back to the right. While refueling, hang the tethered fuel cap from the hook on 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. An alternate fuel door release is located inside the trunk behind a panel on the driver's side of the vehicle. Pull the handle to release the fuel door. 6-8
