2025—2026 EX5 low-speed alert sound: check software and tone before replacing the sounder

If an EX5 sounds different during low-speed manoeuvring, a changed sound alone does not justify replacing the sounder. A factory update notice explicitly added AVAS tone choices for Australian 2025 and 2026 model-year (MY25 and MY26) EX5. Checking software and the selected tone helps avoid treating a function change as hardware damage.

Which sound changed in this update?

Geely Australia's Flyme Auto S 1.2.0 notice, dated Feb 4, 2026, lists MY25 and MY26 EX5 Complete and Inspire. Item 3 concerns AVAS, the low-speed pedestrian alert function, and offers three tone choices:[Factory update notice][R03]

| Tone name | Position in the update notice |
| --- | --- |
| Classic | Existing tone |
| Milky Way | Added choice |
| Constellation | Added choice |

Before comparing sounds, check that the same tone is being compared. Different software or selected tones on otherwise identically equipped EX5 vehicles do not establish that either needs replacement parts.

Separate drive-mode confirmation from AVAS complaints

Item 5 of the same notice also describes a confirmation notification when changing driving modes. This is a separate function from the low-speed pedestrian tone in item 3.[Update items 3 and 5][R03]

For a workshop, distinguish sound during low-speed travel from sound occurring exactly when the driving mode changes. If a new confirmation follows a mode change but the order says “abnormal low-speed sounder”, the complaint may begin with the wrong component. Recording the functions separately does not establish which speaker or controller each uses. [To be verified]

Tone changes explain behaviour without deciding replacement

First match the software version, selected AVAS tone and circumstances. If these match a tone change added by the update, identify it as a functional change rather than buying a sounder because the tone is unfamiliar.

If the concern is that the alert function is not working as the vehicle requires, rather than merely sounding different, have the service centre inspect actual operation before deciding whether hardware is involved. The release date establishes only the start of release. The local brand dealer's OTA page also notes that actual dates depend on staged rollout, so a date cannot prove that a vehicle has installed 1.2.0.[Release-channel explanation][R04]

Scope and verification

This article covers only the Australian model years and trims above, and the function changes in the 1.2.0 notice. It does not extend to other markets, models or later software. The original is an OTA update notice without a recall VIN range and is not a sounder service bulletin. No public data was available in the reviewed material for sounder OE numbers, connectors, separate supply scope, sound-pressure or electrical diagnostic limits. [To be verified] Verify replacement compatibility using the VIN and local Australian manufacturer parts catalogue, and establish individual software status from actual records.
