Caution: Fuel vapor is highly flammable. It burns violently, and that can cause very bad injuries. Do not smoke if you are near fuel or refueling the vehicle. Keep sparks, flames and smoking materials away from fuel.

The fuel cap can be on either or both sides of the vehicle depending on option content.

To take off the cap, turn it slowly counterclockwise.

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.

When reinstalling the cap, turn it clockwise until it is tight.

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 .

If the vehicle has dual tanks, fill the driver side tank, or forward tank, first. The fuel gage will give better readings this way. The gage will show the total fuel left in both tanks.

If the vehicle is a C4/C5 model and has dual tanks, the engine must be off when refueling or the fuel transfer system may become inoperable.

If the vehicle has a single tank with dual fillers, where there is a filler on each side of the vehicle, do not attempt to fill the tank through both fillers at the same time. Do not fill the tank with both caps removed or over-filling the tank and fuel spillage can result.
