BYD Austria published this bulletin on 28 Sep 2026 for a roll-out in October – November 2026. The release carries multimedia version 13.1.33.2608180.1.18.3.5.2606100.2, printed as one string. Everything below is translated from the German PDF; we have not installed this release on a car. The same release for the all-electric model is documented under BYD Seal U V2.3.0.
Overview#

- OTA icon added to the top status bar, shown when a new update is available.
- Switch added for the lead-vehicle start reminder under Driver Assistance.
Optimised
- Navigation experience optimised (in supported countries only).
- Quick deactivation of the driver monitoring system optimised (selected models).
- Energy-consumption display optimised (DM-i only).
- Owner’s manual updated on ACC/ICC in trailer mode and on the light-switch functions.
New features#
Parking-light switch#
A new button sets the parking lights. BYD’s screen places it under Settings → Lighting → Exterior lighting, as a “Parking lights” switch below headlight control and adaptive front lighting. Available in some countries only.
Cloud control for window ventilation and parking lights#
The BYD app can now open the windows for ventilation and switch off the parking lights remotely. Before the windows open, the app asks for confirmation: “About to activate Window Ajar. Please pay attention to the surroundings.” Available in some countries only.
ICC/ACC in trailer mode#
Intelligent cruise control (ICC) and adaptive cruise control (ACC) can now be used in trailer mode when towing a light trailer; with a heavy trailer, ACC is available. The weight class is chosen under Settings → Vehicle → Driving control → Trailer mode.
OTA icon in the status bar#
An OTA icon appears in the top status bar when a new OTA update is available.
Lead-vehicle start reminder#
A new switch under Settings → ADAS → Driver Assistance. When you are driving manually, the system uses the front millimetre-wave radar and/or the front camera to detect whether the vehicle ahead is moving off. When it does, the driver is told by a message in the instrument cluster and an audible signal, as a reminder to start driving.
Optimisations#
Navigation#
A floating navigation window has been added: the next turn and its distance stay visible over other screens. In some countries only.
Quick deactivation of driver monitoring#
Driver monitoring (DMS) can be switched off from its tile in quick access. A confirmation dialog, “Deactivate driver monitoring system?”, offers Cancel (with a three-second countdown) and OK. Only on selected models, and only on vehicles fitted with DMS.
Energy-consumption display (DM-i only)#
Settings → Energy → Energy consumption now has four tabs:
- Current trip: distance, driving time, electricity (kWh) and fuel (L), and how the energy was split between drive, air conditioning, electrical consumers and other uses.
- Trip meters: two subtotals, each with distance, driving time, electricity and fuel, and each resettable.
- Time statistics: electricity (kWh) and fuel (L) per day across a chosen month, with the month’s averages in kWh/100 km and L/100 km.
- Total: odometer, distance driven in hybrid and in electric mode, driving time, and average electricity and fuel consumption.
Owner’s manual#
The owner’s manual has been updated on ACC/ICC in trailer mode and on the light-switch functions.
Notes#
- DAB favourites (fixed): on some Seal U vehicles, saved DAB favourite stations could be lost after the car was restarted. V2.3.0 changes the behaviour so they are kept. The slide names the Seal U, and it appears in both the DM-i and the EV bulletin.
- BYD Austria issued this bulletin and the EV one on the same day, from the same deck. The EV bulletin adds automatic low beam and more detail on navigation, and has no energy-consumption section.
- The trailer-mode screen in the bulletin offers “0–99 kg light trailer” and “100–1300 kg heavy trailer” and shows a car badged Seal U EV; the V2.2.0 bulletin showed 100–750 kg. BYD does not say which range applies to which model, so treat the figures on that screen as illustrative.
- None of the bulletin’s images are reproduced. Several interface images carry garbled text (a sidebar entry reading “Energig”) and look like rendered illustrations rather than captures from a car.
What we have not verified#
- This is a translation of BYD Austria’s bulletin, not a test: we have not installed V2.3.0 on a Seal U DM-i.
- The bulletin was published by BYD’s Austrian importer. The release itself is the European one, but roll-out dates are given for Austria, and a few items are country-specific (parking lights, cloud functions, navigation).
- Availability of individual features can depend on trim, model year and the head-unit hardware.
