NOTICE
When refueling on unlevel ground, the fuel gauge may not point to the F position. It is not a malfunction. If you move your vehicle to a level ground, the fuel gauge will move to the full position.

WARNING
Gasoline is highly flammable and explosive. Failure to follow these guidelines may result in SERIOUS INJURY or DEATH:

• Read and follow all warnings posted at the gas station.
• Before refueling, note the location of the Emergency Gasoline Shut-Off, if available, at the gas station.
• Before touching the fuel nozzle, you should eliminate the potential build-up of static electricity by touching a metal part of the vehicle, a safe distance away from the fuel filler neck, nozzle, or other gas source, with your bare hand.
• Do not use cellular phones while refueling. Electric current and/or electronic interference from cellular phones can potentially ignite fuel vapors and cause a fire.
• Do not get back into a vehicle once you have begun refueling. You can generate a build-up of static electricity by touching, rubbing, or sliding against any item or fabric capable of producing static electricity. Static electricity discharge can ignite fuel vapors causing a fire. If you must re-enter the vehicle, you should once again eliminate potentially dangerous static electricity discharge by touching a metal part of the vehicle, away from the fuel filler neck, nozzle or other gasoline source, with your bare hand.
• When refueling, always move the shift lever to the P (Park) position, set the parking brake, and place the ignition switch in the LOCK/OFF position.
• Sparks produced by electrical components related to the engine can ignite fuel vapors causing a fire.
• When using an approved portable fuel container, be sure to place the container on the ground prior to refueling. Static electricity discharge from the container can ignite fuel vapors causing a fire. Once refueling has begun, contact between your bare hand and the vehicle should be maintained until the filling is complete.
• Use only approved portable plastic fuel containers designed to carry and store gasoline.
• Do not use matches or a lighter and do not smoke or leave a lit cigarette in your vehicle while at a gas station, especially during refueling.
• Do not over-fill or top off your vehicle tank, which can cause gasoline spillage.
• If a fire breaks out during refueling, leave the vicinity of the vehicle, immediately contact the manager of the gas station, and then contact the local fire department. Follow any safety instructions they provide.
• If pressurized fuel sprays out, it can cover your clothes or skin and thus subject you to the risk of fire and burns. Always remove the fuel cap carefully and slowly. If the cap is venting fuel or if you hear a hissing sound, wait until the condition stops before completely removing the cap.
• Always check that the fuel cap is installed securely to prevent fuel spillage in the event of an accident.

Information
Make sure to refuel your vehicle according to the “Fuel Requirements” suggested in the Introduction chapter.

NOTICE
Do not spill fuel on the exterior surfaces of the vehicle. Any type of fuel spilled on painted surfaces may damage the paint. If the fuel filler cap requires replacement, use only a genuine HYUNDAI cap or the equivalent specified for your vehicle. An incorrect fuel filler cap can result in a serious malfunction of the fuel system or emission control system.
