Frequently asked questions

Is this official BYD content?

No. It is an AutoTechHelp source-backed owner help page with official BYD/manual/safety sources cited by market.

Does this apply to SEALION 5, SEALION 6 or Seal U?

No. SEALION 7 facts are not merged with SEALION 5 DM-i, SEALION 6, SEAL U, SEAL, TANG or China Sea Lion 07 EV unless an official source proves exact applicability.

Which manuals were extracted?

The official Netherlands LHD manual, official Australia RHD handbook and official Cyprus RHD manual were downloaded and summarized.

Are maintenance intervals real?

Yes where published: intervals are taken from official owner manuals and kept region-scoped.

Are DTC/error codes published?

No. Exact DTC codes are not published until an official SEALION 7 diagnostic or service source confirms them.

Are warning lights official?

Published warning-light pages are based on official owner-manual warning-light/message tables.

Can imported-car owners use this?

Use it as a source map, then confirm VIN, market, trim, software and warranty status with an authorized BYD dealer.

Is this a repair guide?

No. HV battery, charging internals, brakes, steering, airbags, ADAS, wiring, rescue and repair procedures remain service-only.

How should market differences be handled?

Follow the manual and warranty/service document for the exact region and VIN; LHD and RHD documents are not merged silently.

How often should sources be rechecked?

Official manual, warranty, recall and safety-rating sources should be rechecked before publishing new technical facts.
