Confirmed facts

Confirmed facts
TopicSource-backed position
Dmi SpecsDM-i Boost, Comfort and Design stay market-scoped. The official Europe page confirms Super DM, 18.3 kWh headline battery, 70 km plus EV range, up to 1080 km combined range and 18 kW DC charging.
Dmi IdentitySEAL U DM-i is the plug-in-hybrid Super DM branch; engine, fuel, EHS and HEV-mode facts do not apply to the EV.
Not MergeSEAL U, SEAL U DM-i, SEALION 6, SEAL sedan, SEALION 5/7 and Song Plus are not interchangeable content buckets.
Sealion IdentitySEALION 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.

Owner checklist

  • Confirm market, model year, trim, steering side and powertrain before applying a figure.
  • Use the official source links at the bottom for the current wording and documents.
  • Keep high-voltage, charging, braking, steering, airbag, ADAS, towing and rescue work with authorized BYD service.
  • For imported cars, verify VIN, software, charging standard and warranty registration locally.

Safety boundary

This page is owner guidance, not a repair manual. Do not perform high-voltage, hybrid, brake, steering, airbag, ADAS, wiring, towing or rescue procedures from web content.

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.
