• Additional voice-recognition language support; the cited Danish archive specifically records Danish
• Google-based search in the navigation system
• Karaoke compatibility with a BYD microphone
• Three alarm-volume levels
• A password option for driver functions as an anti-theft measure

Optimisations listed by BYD

This summary is translated and rewritten from BYD’s official SEAL 2022–2025 software archive. The previous wording about “low-temperature DC charging” was not supported by that release record; BYD describes an optimisation to DC charging-curve stability.

Step by step: prepare for an offered update

1. Confirm that this guide matches the 2022–2025 SEAL generation and record the complete installed version.
2. Park safely and read the full 1.4.0 notification shown by your own vehicle.
3. Meet the battery, connection and other requirements displayed by the car.
4. Record important preferences, then start or schedule the installation only through the vehicle’s update screen.
5. Leave the car unused and do not interrupt installation unless the vehicle instructs you to.

For the complete workflow, use our BYD OTA update guide with the official manual for your vehicle. Never use unofficial firmware.

Step by step: check the result

1. After completion, record the full version displayed by the vehicle.
2. While parked, check saved preferences, navigation, voice assistance and phone pairing.
3. Test only functions listed in your vehicle’s own notification; regional availability may differ from the cited archive.
4. If a warning or installation failure remains, retain the exact message and full version for an authorised BYD repairer.
