Fuel tank opening for unleaded gasoline

To help prevent incorrect fueling, your vehicle has a fuel tank opening that only accommodates the special nozzle on unleaded fuel pumps.

If the malfunction indicator lamp illuminates

The malfunction indicator lamp may illuminate erroneously if refueling is per- formed repeatedly when the fuel tank is nearly full.

WARNING

When refueling the vehicle

Observe the following precautions while refueling the vehicle. Failure to do so may result in death or serious injury.

After exiting the vehicle and before opening the fuel door, touch an unpainted metal surface to discharge any static electricity. It is important to discharge static electricity before refueling because sparks resulting from static electricity can cause fuel vapors to ignite while refueling.

Always hold the grips on the fuel tank cap and turn it slowly to remove it. A whooshing sound may be heard when the fuel tank cap is loosened. Wait until the sound cannot be heard before fully removing the cap. In hot weather, pressurized fuel may spray out the filler neck and cause injury.

Do not allow anyone that has not discharged static electricity from their body to come close to an open fuel tank.

Do not inhale vaporized fuel.

Fuel contains substances that are harmful if inhaled.

Do not smoke while refueling the vehicle.

Doing so may cause the fuel to ignite and cause a fire.

Do not return to the vehicle or touch any person or object that is statically charged.

This may cause static electricity to build up, resulting in a possible ignition hazard.

When refueling

Observe the following precautions to prevent fuel overflowing from the fuel tank:

Securely insert the fuel nozzle into the fuel filler neck.

Stop filling the tank after the fuel nozzle automatically clicks off.

Do not top off the fuel tank.

After refueling, turn the fuel tank cap until you hear a click. Once the cap is released, it will turn slightly in the opposite direction.

Closing the fuel tank cap

Tighten the fuel tank cap until 1 click is heard. Otherwise a malfunction indica- tor lamp may come on.
