Caution: Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the pump island. Turn off the engine when you are refueling. Do not smoke if you are near fuel or refueling the vehicle. Do not use cellular phones. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling the vehicle. This is against the law in some places. Do not re-enter the vehicle while pumping fuel. Keep children away from the fuel pump; never let children pump fuel.

The fuel filler cap is located behind a hinged door on the passenger's side of your vehicle. It is tethered to the door to prevent loss while refueling. Make sure that water, snow, and dirt are kept away from the filler cap and filler pipe nozzle.

To remove the fuel cap, turn it slowly to the left (counterclockwise). It will require about 1/2 of a turn to remove the cap. The fuel cap has a spring in it; if you let go of the cap too soon, it will spring back to the right (clockwise).

Caution: If you get fuel on yourself 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 the 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. Clean fuel from painted surfaces as soon as possible. See Cleaning the Outside of Your Vehicle .

When you put the fuel cap back on, turn it to the right (clockwise) about 1/4 of a turn 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 and may cause the malfunction indicator lamp to come on. See Malfunction Indicator Lamp .

Notice: If you need a new fuel cap, be sure to get the right type. Your dealer/retailer can get one for you. If you get the wrong type, it may not fit properly. This may cause the malfunction indicator lamp to light and may damage the fuel tank and emissions system. See Malfunction Indicator Lamp .
