Frequently asked owner questions about manuals, trims, maintenance, warning lights and accessories.

What is confirmed

This FAQ consolidates the published BYD SEALION 5 DM-i content set and explains what is official, what is market-specific, what still needs extraction and why unsafe repair/DTC content is blocked.

Scope and safety boundaries

Use this FAQ as a source map and owner checklist, not as a repair manual, diagnostic manual or warranty certificate.

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.
