Tesla red brake icon: driver input, FSD, or AEB?
Unconfirmed: a user discussion on forums questions what the red brake icon in the lower-left brake graph of the display means. According to the observations cited, the icon turns red when the driver presses the brake pedal, but not during FSD hard braking. It is also unclear whether AEB consistently triggers it. The authors ask whether FSD and other assistance features use different indicator logic than AEB, and whether dashcam telemetry and instrument-cluster displays can differ.…
- Per users, the red icon appears when the driver presses the brake pedal.
- Per users, it does not appear during FSD hard braking; AEB unconfirmed.
🔎 Why it matters: No official confirmation: users claim the red icon in the lower-left brake graph reflects the pedal but not FSD hard braking. Telling braking sources apart affects how telemetry logs are interpreted.
📈 Upside: If Tesla used distinct colors or lab records, each braking event would be attributed to its actual source.
📉 Risk: Without that distinction, dashcam records could attribute system braking to the driver, or the reverse.
