BYD SEALION 6

This page provides an independent guide to the logbook servicing requirements for the BYD SEALION 6 plug-in hybrid electric vehicle (PHEV) in Australia. It covers the official service schedule, specific maintenance requirements for the hybrid powertrain, and safety warnings for the high-voltage system. Note that trim names, specifications and prices reflect a compiled dataset (October 2026) and that BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website. Official service/warranty page: https://bydautomotive.com.au/service-and-warranty. Because this is an independent guide, all details must be confirmed with an authorised BYD dealer.

Servicing Intervals and Schedule

The BYD SEALION 6 requires regular maintenance to ensure the proper operation of both its 1.5-litre petrol engine and its electric drive components. According to official guidelines, the standard BYD Sealion 6 logbook service intervals are set at 12 months or 20,000 km, whichever occurs first. Subsequent logbook services follow the exact same pattern: 40,000 km or 24 months, 60,000 km or 36 months, 80,000 km or 48 months, 100,000 km or 60 months, and 120,000 km or 72 months.

This interval schedule applies across the entire model range, including the Essential Standard Range, Dynamic Extended Range, Premium Standard Range, and Premium Extended Range variants. Adhering to these stipulated timeframes or distance milestones is critical. If the vehicle is primarily driven under severe operating conditions, the manufacturer advises that maintenance intervals may need to be shortened to protect the powertrain. For those seeking details on a BYD Sealion 6 capped price servicing schedule for Australia, exact service prices or a capped price amount are not provided in this dataset. Pricing is published by the manufacturer and individual dealerships, so owners should confirm with BYD Automotive Australia directly for the most current service costs.

PHEV Run-In Service

Unlike pure electric vehicles, the BYD SEALION 6 features a plug-in hybrid system (DM series) that incorporates internal combustion engine components alongside the high-voltage Blade Battery. Because of this dual-mode powertrain, the initial maintenance schedule differs from standard EV models. The manufacturer requires an initial run-in service at six months or 3,500 km of HEV (hybrid electric vehicle) trip operation, whichever comes first. This initial visit is specific to DM vehicles with HEV components.

Service Record Items

The logbook servicing for the BYD SEALION 6 involves a thorough inspection and replacement schedule for numerous fluid and hardware systems. The official service record for DM series vehicles mandates the replacement of specific components over the vehicle’s lifespan to maintain the integrity of the powertrain.

The documented replacement items include brake fluid, engine oil and the corresponding filter, the engine air filter element, the fuel filter, and the carbon canister filter. Additionally, technicians will replace spark plugs, engine coolant, and the e-motor controller coolant.

The exact per-item intervals, such as a precise spark plug change interval, are not explicitly provided in the facts and must not be assumed. All component replacement schedules are subject to manufacturer specifications, and owners should refer to the official owner’s manual for detailed mileage or time requirements for each item.

High-Voltage System and Safety

The BYD SEALION 6 is equipped with either an 18.3 kWh or 26.6 kWh BYD Blade Battery, operating as part of a high-voltage electrical network. Any maintenance involving the high-voltage system, brakes, steering, airbags, ADAS calibration, or charging hardware must be performed by an authorised BYD dealer or a qualified technician.

Never attempt to follow step-by-step repair instructions found online for these critical systems. Owners must not touch, open, or attempt to repair any high-voltage orange cables located under the bonnet or throughout the vehicle chassis. Attempting such work on the electrical system is highly dangerous and poses severe safety risks.

Data Gaps and Unknown Specifications

While the BYD SEALION 6 is equipped with a 60 L fuel tank, specific fuel grade requirements are not confirmed in the official brochure. Similarly, detailed maintenance requirements—such as a specific engine oil grade, exact oil capacity, or part numbers for filter replacement—are not listed. Owners seeking engine specifications for service purposes must refer to the official owner’s manual.

Other unlisted specifications in the compiled dataset include the exact towing capacity, ground clearance, and the vehicle’s ANCAP safety rating. Official prices are not published on the model page or brochure, so determining a precise BYD Sealion 6 price in Australia or finding the final driveaway price for Melbourne, Sydney, or Brisbane requires contacting a dealership directly. Details on how the DM-i super hybrid system operates can be requested through official BYD channels, as technical operating logic is not detailed here.

Warranty Boundaries and Exclusions

The BYD SEALION 6 is covered by a 6-year or 150,000 km new vehicle warranty, while the traction battery and drive unit (including the drive motor and drive motor controller) are covered for 8 years or 160,000 km. To maintain this warranty, all servicing must be conducted strictly per the manufacturer’s recommendations.

The warranty specifically excludes damage from failure to follow correct charging procedures, odometer tampering, water ingress from deep-water wading, or loading beyond official specifications. Unauthorised modifications and third-party conversions completely void the warranty. Damage resulting from the use of non-BYD genuine parts is also excluded. Confirm with BYD Automotive Australia if you have any questions about specific warranty boundaries.
