Cybertruck FSD 12.5.5.3 (2024.39.5 and 2024.38.4) Release Notes — tilted mirrors, Spotify Free, Sentry Mode improvements

Tesla began rolling out the new Full Self-Driving (FSD) software release to its Cybertruck EV pickup trucks on Sunday. The version is FSD 12.5.5.3 (firmware version 2024.39.5).

The automaker deployed the 2024.39.5 update for the new FSD v12.5.5.3 roll out. But kept the Release Notes to a minimum and they’re almost the same as the previous 2024.38.4 (read below).

The features unlocked in the 2024.38.4 and for some Cybertruck owners in the latest 2024.39.5 updates are mostly gone out to other Tesla vehicles weeks and months ago (e.g. Spotify Free and Slacker Radio, etc.).

However, one feature is specific to the Cybertruck in these new updates — Custom Mirror Tilted Positions (details below). Cybertruck also received energy consumption improvement while the truck is using Sentry Mode in the 2024.38.4 and 2024.39.5 updates.

The FSD v12.5.5.3 Release Notes also mention that this is an early access build. However, several normal owners even from Canada reported during the last two days that they received this update on their Cybertrucks.

Full Self-Driving (Supervised)

Under your supervision, Full Self-Driving (Supervised) can drive your Tesla almost anywhere. It will make lane changes, select forks to follow your navigation route, navigate around other vehicles and objects, and make left and right turns. You and anyone you authorize must use additional caution and remain attentive. It does not make your vehicle autonomous. Do not become complacent.

Full Self-Driving (Supervised) is enabled on your vehicle. To use the feature, press the right scroll wheel button once. You can disable Full Self-Driving (Supervised) in Autopilot Settings.

Vision-Based Attention Monitoring (with sunglasses)

Tesla FSD v12.4 utilizes the vehicle’s cabin camera (located above the rearview mirror) for vision-based attention monitoring of the driver that removes nags but introduces ‘Strikeouts’ of inattentiveness. — Tesla FSD v12.4 and later versions utilizes the vehicle’s cabin camera (located above the rearview mirror) for vision-based attention monitoring of the driver that removes nags but introduces ‘Strikeouts’ of inattentiveness.

When Full Self-Driving (Supervised) is enabled, the driver monitoring system primarily relies on the cabin camera to determine driver attentiveness. Cabin camera must have clear visibility (e.g., camera is not occluded, eyes, arms, are visible, there is sufficient cabin illumination, and the driver is looking forward at the road). In other circumstances, the driver monitoring system will primarily rely on torque-based (steering wheel) monitoring to detect driver attentiveness.

If the cabin camera detects inattentiveness, a warning will appear. The warning can be dismissed by the driver immediately reverting their attention back to the road ahead. Warnings will escalate depending on the nature and frequency of detected inattentiveness, with continuous inattention leading to a strikeout.
