BYD SEALION 5 DM-i official sources

Official, regional and research sources used for this content set.

What is confirmed

This source map separates S0 manufacturer pages, the direct BYD New Zealand owner handbook, EU/UK/Romania manual hubs, regional warranty/service pages, dealer PDFs, secondary market context and unverified research leads. Every published guide links to the exact source rows it uses.

Scope and safety boundaries

A source being stored does not make every fact universal; apply each fact only to the market, language, trim and model year covered by that source.

TopicStatus
Official model pagesPublished with citations
NZ owner handbookExtracted and summarized
EU/UK/Romania manualsDiscovery/review
DTC codesNot published without official diagnostic source
Repair/HV/ADAS proceduresService-only review

Check market, VIN, trim, battery, software and official BYD/dealer confirmation. Safety-critical topics stay service-only.

Frequently asked questions

Is this official BYD content?

No. It is an AutoTechHelp source-backed owner help page. Official BYD sources are cited and scoped by market.

Which public slug is used?

AutoTechHelp keeps the existing public URL slug byd-sealion-5-dmi. The prompt spelling byd-sealion-5-dm-i is treated as an alias.

Does this apply to SEALION 6 DM-i, SEAL U DM-i or Song Plus DM-i?

No. SEALION 5 DM-i facts are not merged with related BYD models unless an official source proves exact compatibility.

Was an owner handbook found?

Yes. A BYD New Zealand owners-manual page provides a direct SEALION 5 owner handbook PDF, extracted for owner-safe chapters, maintenance and warning lights.

Are EU and UK manuals complete?

Not yet. EU, UK and Romania owner-manual hubs are stored as official discovery sources while direct regional manual assets still need extraction.

Are DTC codes published?

No. Model-specific DTC/error-code pages remain blocked until an official diagnostic or service source confirms exact codes.

Can I use the maintenance schedule globally?

Use it as a source-scoped New Zealand/Australia RHD handbook schedule and confirm your own market by VIN, local manual or BYD service.

Is this a repair guide?

No. HV battery, hybrid system, brakes, steering, airbags, ADAS, fuel system, wiring, towing/recovery and repair procedures remain service-only.

Can imported-car owners use this?

Use it as a source map. Before applying any fact, confirm market, VIN, trim, battery, software and dealer support.

How often should sources be rechecked?

This seed stores checked dates and review tasks. Dynamic manuals, warranty pages and recall sources should be rechecked as BYD publishes updates.
