Misfuel risk Moderate

New US Crown lines are hybrid gasoline; verify pump handle at station—diesel is not used.

If the engine was not started

Do not prime hybrid system with contaminated fuel—ignition off until drain completes.

If the engine was started

Hybrid fuel system inspection, filter service, and DTC review per OEM.

Access procedure

  1. Relieve fuel system pressure per Toyota service information (fuel pump relay/fuse, crank briefly if directed).
  2. Disconnect the battery negative terminal.
  3. Access the in-tank fuel pump module via the OEM access opening (rear seat or trunk panel on most US models).
  4. Disconnect electrical connector and quick-connect fuel lines; cap lines to limit vapor release.
  5. Remove the pump lock ring with the specified tool; lift the module carefully to avoid damaging the level sender.
  6. Extract contaminated fuel with approved equipment; inspect the tank interior through the opening.
  7. Reinstall with a new pump O-ring/gasket; reconnect lines and verify no leaks before starting.
  8. Prime and clear codes per Toyota repair manual; road test when fuel quality is confirmed.

The 2023+ US Crown is a distinct hybrid model for North America—not the same as JDM Crown sedans.

Can I use regular gas in a Crown hybrid?

Follow the fuel door label; if wrong fuel was added, drain before starting regardless of grade.
