Toyota Prius: Refueling

Opening the fuel tank cap

The fuel tank of the 2024 Toyota Prius has a special structure that requires a reduction in fuel tank pressure before refueling. After pressing the opener switch, it will take several seconds for the vehicle to be ready for refueling.

Before refueling the vehicle

• Close all the doors and windows, and turn the power switch to OFF.
• Confirm the type of fuel.

Fuel types

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.

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 of 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.

WARNING

Do not top off the fuel tank.

NOTICE

Refueling

• Finish refueling within 30 minutes.

  If more than 30 minutes passes, the internal valve closes. In this condition, fuel may overflow during the refueling process. Press the fuel filler door opener switch again.

• Make sure that the fuel filler door lock is not pushed by the fuel nozzle boot, etc. If the lock is held, the internal valve closes and fuel may overflow. To prevent it, press the fuel filler door opener switch again.

• Do not spill fuel during refueling.

  Doing so may damage the vehicle, such as causing the emission control system to operate abnormally or damaging fuel system components or the vehicle's painted surface.

Opening the fuel tank cap

1. Press the opener switch to open the fuel filler door.

The fuel filler door will open approximately 10 seconds after pressing the switch. A message will appear on the multi-information display in the instrument cluster to indicate the progress of the fuel filler door opener before refueling can begin.

2. Turn the fuel tank cap slowly to open and hang it on the back of holder on the fuel filler door.

If the fuel filler door cannot be opened

Consult your Toyota dealer.

Closing the fuel tank cap

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

When "Check Fuel Cap" is displayed on the multi-information display

The fuel tank cap may be unfastened or loose. Turn the power switch to OFF, check the cap and tighten it securely. If the message remains, wait a few seconds and then turn the power switch to OFF once again.

When replacing the fuel tank cap

Do not use anything but a genuine Toyota fuel tank cap designed for your vehicle. Doing so may cause a fire or other incident which may result in death or serious injury.
