Confirmed facts
| Topic | Source-backed position |
|---|---|
| Maintenance Au | Australia SEALION 6 maintenance is sourced from the official AU handbook: first service within 6 months / 3,500 km HEV mileage, then market-specific total-mileage and HEV-mileage intervals. |
| Au Manual | The Australia SEALION 6 handbook is imported under AU/RHD scope and does not overwrite Europe DM-i data. |
| Sealion Identity | SEALION 6 is the Australia/RHD regional PHEV entity. It is related to the SEAL U DM-i family but remains separate until exact equivalence is proven by source and VIN. |
| No Dtc | No SEAL U-specific numeric DTC/error-code pages are published in this rollout because no official or authorized exact diagnostic source was found. |

Frequently asked questions
Is this official BYD text?
No. It is an AutoTechHelp editorial summary based on cited official or review-labelled sources.
Which version does it apply to?
Check whether the vehicle is SEAL U EV, SEAL U DM-i or Australia SEALION 6, then verify market, year, trim and steering side.
Can I mix Europe and Australia data?
No. Australia SEALION 6 facts are useful for comparison but remain AU/RHD-scoped until an official source proves exact equivalence.
Are DTC/error codes published?
No SEAL U-specific numeric DTC pages are published here without official or authorized diagnostic documentation.
Is this a repair manual?
No. Safety-critical systems remain service-only and the page intentionally avoids repair or wiring procedures.
What should I record before contacting service?
Record the exact message or icon, color, mileage, SOC/fuel level, charging or driving state, weather, recent service and accessory/software changes.
Why are some names left in English?
Trim names, DM-i, Super DM, V2L, DTC, ADAS and source market names are kept close to official wording to avoid mistranslation.
How often are sources checked?
AutoTechHelp stores checked dates and keeps safety-critical or conflicting topics in review until sources are strong enough.
Can imported cars use this page?
Use it as a source map and checklist, then confirm by VIN, local dealer support and the vehicle market record.
Are manuals copied here?
No. Manuals are linked and summarized in original wording; full manual text and protected images are not copied.
