Update 2026.38.5 (FSD 14.3 Lite & 14.3.12) - Release Notes

Spread holiday fear year round with Halloween Mode. Put a Ghost Costume on your car visualization. Turn on Trick or Treat Mode to play spooky sounds and flicker the lights when visitors approach. Schedule a haunting light show, and turn your car into a chilling Photobooth!

The center display now features higher quality images of your Tesla, and an enhanced park scene environment.

Emergency Drive Away lets you shift into Drive while a Supercharger cable is still connected. Use it only in an emergency: driving away with the cable attached will damage your vehicle and the Supercharger, and you may be responsible for repair costs. When you activate this feature, short recordings from your vehicle's cameras are shared with Tesla.

You can now see a detailed view of select Tesla Superchargers by tapping "View Site Map." When navigating to a pilot location, the site layout and live occupancy (Available / Occupied / Down) will be displayed upon arrival.

Set your desired Arrival Energy for any trip from your phone. Open the location tab in the Tesla Mobile App, enter your destination, and tap Set Arrival Energy. Requires Mobile App v4.58.0 or later.

Low beams will automatically adjust their aim based on driving conditions and nearby traffic to maximize your visibility while reducing glare for other road users.

Automatic Collision Evasion activates Full Self-Driving (Supervised) to try to keep your vehicle safe and then continue driving. It can engage while you are driving manually and detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.

See your Owner's Manual for more details.

Full Self-Driving (Supervised) v14.3.12 includes:

- Upgraded the Reinforcement Learning (RL) stage of training the FSD neural network, resulting in improvements in a wide variety of driving scenarios.

- Upgraded the neural network vision encoder, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding.

- Rewrote the AI compiler and runtime from the ground up with MLIR, resulting in 20% faster reaction time and improving model iteration speed.

- Mitigated unnecessary lane biasing and minor tailgating behaviors.

- Increased decisiveness of parking spot selection and maneuvering.

- Improved parking location pin prediction, now shown on a map with a P icon.

- Enhanced response to emergency vehicles, school buses, right-of-way violators, and other rare vehicles.

- Improved handling of small animals by focusing RL training on harder examples and adding rewards for better proactive safety.

- Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping — driven by training on hard RL examples sourced from the Tesla fleet.

- Improved handling for rare and unusual objects extending, hanging, or leaning into the vehicle path by sourcing infrequent events from the fleet.

- Improved handling of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.

- Improved driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.

- Unified the model between Actually Smart Summon, FSD, and Robotaxi for more capable and reliable behavior.

- Help Tesla improve Self-Driving by selecting an intervention reason on the main screen after taking over.

- You can now see distance traveled in FSD (Supervised) without an intervention. The Self-Driving App will also show your longest intervention-free streak.

- Parking options now display on the map when arriving at your destination.

Upcoming Improvements:

- Expand reasoning to all behaviors beyond destination handling.

- Add pothole avoidance.

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

FSD (Supervised) v14.3 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 pull over or park: in a Parking Lot, on the Street, in a Driveway.

- 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

Brake Confirm requires the driver to press and release the brake pedal before FSD (Supervised) can be activated. When Brake Confirm is disabled, pressing the button will allow Self-Driving to apply the brakes and engage FSD (Supervised). If driver detection requirements are not met or if FSD (Supervised) does not detect a driver, you will be required to press and release the brake pedal to confirm. You can enable Brake Confirm in Self-Driving > Brake Confirm.

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, and Pull Over 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 Self-Driving visualization on the center display.

This update includes important security fixes and improvements.
