Filling the Tank {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 your engine when you are refueling. Do not smoke if you are near fuel or refueling your vehicle. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling your vehicle - this is against the law in some places. Keep children away from the fuel pump; never let children pump fuel. The fuel cap is located on the driver's side of the vehicle. Some vehicles may be equipped with a fuel door. Open the door to access the fuel cap. Some vehicles may be equipped with a locking fuel cap. Use the fuel cap key to unlock the fuel cap. If you ever need a replacement key, your dealer can help you get one. To remove the fuel cap, turn it slowly counterclockwise. While refueling, let the fuel cap hang by the tether, if it has one. 5-8
