Tesla’s upcoming 2025.8.x software update introduces advanced emergency vehicle detection features, as uncovered by firmware sleuth greentheonly. The system will alert drivers when sirens are detected and automatically lower media volume to improve awareness. According to the firmware code, the feature requires microphone permissions but processes sound data locally unless data sharing is enabled.

The update leverages Tesla’s existing internal microphone (single in most models) and camera systems to enhance emergency response recognition. Notably, the functionality will work regardless of whether Full Self-Driving (FSD) or Autopilot is active. This follows Tesla’s pattern of refining safety features via over-the-air updates, such as recent improvements to towing range estimates through trailer profiles.
Tesla’s help text confirms the alerts prioritize driver awareness without external data transmission. The feature’s rollout timeline remains unspecified, but greentheonly’s track record suggests accuracy in predicting unreleased updates. This follows other incremental refinements, like the Cybertruck’s display adjustments based on owner feedback.
