Update 2026.20.5.1 (FSD 14 Lite) - Release Notes

FSD (Supervised) v14 Lite includes:

- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.

- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.

- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.

- Introduced parking, unparking, and reversing capabilities.

- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.

- Speed Profiles are now available at all times, to further customize driving style preference.

A button will appear on the screen when driver requirements are met. Driver requirements include (but are not limited to):

- Driver is seated in driver's seat

- Driver is buckled

- Cabin Camera is unobstructed

To engage FSD (Supervised), tap the Start Self-Driving button, then press and release the brake pedal.

This feature does not make your vehicle autonomous and you must remain attentive and be ready to take over at any time. Only a licensed driver authorized to operate the vehicle should be allowed access to the driver's seat position any time the vehicle is not in Theater or Arcade modes.

- You can now select an arrival option such as Parking Lot, Street, Driveway, Parking Garage and Curbside for Robotaxi-style drop offs.

- Your preferences for arrival options and preferred parking positions are persisted for each destination.

FSD (Supervised) will now determine the appropriate speed based on a mix of driver profile, speed limit, and surrounding traffic.

- Introduced new Speed Profile SLOTH, which comes with lower speeds & more conservative lane selection than CHILL.

- Driver profile now has a stronger impact on behavior. The more assertive the profile, the higher the max speed.

- Right scroll-wheel up/down now adjusts Speed Profile setting rather than your precise max speed offset selection in mph/kph.

- Adjust settings like the Speed Profile and Arrival Options directly from the Autopilot visualization on the center display.

Under your supervision, Full Self-Driving (Supervised) can drive your Tesla almost anywhere. It will start from a parked position, make lane changes, select forks to follow your navigation route, navigate around other vehicles and objects, make left and right turns and park at your destination.

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 Start Self-Driving button on the Ul, or press the right scroll wheel button once. You can disable Full Self-Driving (Supervised) in Self-Driving Settings.

You can now send navigation destinations directly to your Tesla. To send from the Mobile App, go to Location > Navigate, add a destination, and tap Send to Car. Requires Mobile App version 4.57.0 or later.

To send from NAVER Maps or TMAP, add a destination and go to Share > Tesla. To send from KakaoMap, add a destination and go to Share > Share Address > Tesla.

Maps now show weather data, including different types of precipitation like rain and snow. You can also view the past hour of weather data to see how conditions have been changing along your route. This feature requires Premium Connectivity. To view, tap the weather icon on the map.

You can now tap on points of interest on the map to explore destinations or begin navigation.

Tesla will now display whether a vehicle has FSD enabled in the Tesla app. In addition, the app will now also display the blue FSD path and even the rainbow road easter egg if it’s enabled in the vehicle.

This requires Tesla app update 4.58.5 or higher and vehicle update 2026.20.6.1 or higher.

With Tesla’s recent addition of license plate customization, they also added a shortcut for it under Controls > Software.

With this update, Tesla tweaked the icon slightly by adding a license plate frame around the license plate image being used for a cleaner look.

In update 2026.20, Tesla started encrypting Dashcam footage. This came at the same time as Tesla expanded recent video footage from 1 hour to up to 24 hours under certain requirements.

Encrypting the videos is an important privacy change, since if your USB drive is pulled from your vehicle, thieves can now have access to up to 24 hours of your driving, potentially revealing your workplace, home, and other important locations.

With this update, Tesla also added a button to the Dashcam Viewer that lets owners easily decrypt a specific clip, making it easier to see the footage if they mount the USB drive to their computer.

Tesla also introduced a tool that lets you decrypt any videos on your computer, as long as you log in to your Tesla account to prove that you own the video footage.

Tesla’s navigation now supports bus lanes, helping drivers be more aware of which lanes they can use.

This is even more important for FSD, so the vehicle can know which lanes are appropriate to drive in without having to read or potentially miss signs.
