How to restart the BYD infotainment screen without a factory reset

Restart and factory reset are not the same

A normal infotainment restart closes and reloads the screen system. It should be tried before a factory reset when the display or audio has stopped responding.

A factory reset can remove saved settings and personal configuration. Do not select Factory Reset merely to restart a frozen screen.

Documented restart steps

Use this only where the vehicle has the physical scroll or volume control described in its owner's manual:

1. Park safely and select P.
2. Confirm that no OTA software update is installing.
3. With the infotainment system already on, locate its physical scroll or volume control.
4. Press and hold that control for approximately three seconds.
5. Release it and allow the infotainment system to restart fully.
6. Test the original function only after the home screen has finished loading.

The current right-hand-drive manuals for the BYD SEAL, DOLPHIN, 2024 ATTO 3 and SEALION 7 document this three-second restart. DOLPHIN SURF documentation identifies a multimedia restart control, but its exact operation still needs confirmation for the UK version. ATTO 2 and ATTO 3 EVO remain unconfirmed.

If a short press only mutes or switches off the display

That is expected on models where the same control has multiple functions. A short press may mute audio, switch off the display or enter the screen saver. The documented restart requires a continuous press for about three seconds.

If it does not restart

1. Do not keep repeating the action while an update is active.
2. Check the owner's manual supplied with the exact model and software version, because controls differ.
3. Record what is frozen: display, sound, cameras, navigation, phone connection or the entire vehicle.
4. Contact a BYD Store or BYD Customer Service if the screen remains unavailable, repeatedly freezes, or affects safety-related information.

Factory Reset warning

BYD Europe currently describes Settings → Version → Factory Reset as a “soft reset” in its online FAQ. Vehicle manuals identify this as a factory reset of the infotainment system. Treat it as a separate last-resort operation and check what personal data and settings will be removed before confirming it.

Never factory-reset, disconnect the 12V battery or pull fuses while an OTA update is active.
