Start with the official local source
The owner’s manual is the place to check the instructions that apply to your vehicle. Begin with the owners or service section of the official BYD website for the country where your car was sold.
Check the document against your car
Compare the model name, model year and local version. If the document offers separate left-hand-drive or right-hand-drive editions, check that detail too. A matching name in an online discussion does not establish that the whole handbook applies.
If you cannot find a clear match
Ask your local BYD support team or dealer to identify the applicable handbook. Keep the document available so you can return to the original instructions.
