2026.28.5 Release Notes

This release updates FSD in Oceania to FSD v14.3.9 and includes the Summer Update features.

FSD (Supervised) v14.3.9

Full Self-Driving (Supervised) v14.3.9 includes:

• The Reinforcement Learning (RL) stage of training the FSD neural network has been upgraded, improving performance across a wide variety of driving scenarios.
• The neural network vision encoder has been upgraded, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding.
• The AI compiler and runtime were rewritten from the ground up with MLIR, resulting in 20% faster reaction time and improving model iteration speed.
• Unnecessary lane biasing and minor tailgating behaviors have been mitigated.
• Parking spot selection and maneuvering are now more decisive.
• Parking location pin prediction is improved and now appears on the map with a P icon.
• Responses to emergency vehicles, school buses, right-of-way violators, and other rare vehicles have been enhanced.
• Handling of small animals is improved by focusing RL training on harder examples and adding rewards for better proactive safety.
• Traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping has been improved, driven by training on hard RL examples sourced from the Tesla fleet.
• Handling for rare and unusual objects extending, hanging, or leaning into the vehicle path has been improved by sourcing infrequent events from the fleet.
• Handling of temporary system degradations has been improved by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.
• Driver monitoring system sensitivity is improved with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.
• After taking over, you can select an intervention reason on the main screen. (New in FSD v14.3.2)
• You can now see distance traveled in FSD (Supervised) without an intervention, and the Self-Driving App will also show your longest intervention-free streak. (Added in FSD v14.3.3)
• Parking options now display on the map when arriving at your destination. (Added in FSD v14.3.4)

Upcoming Improvements

• Expand reasoning to all behaviors beyond destination handling.
• Add pothole avoidance.

Full Self-Driving (Supervised) Down Under

With driver supervision, Full Self-Driving (Supervised) Down Under can drive your Tesla on most roads. It can make lane changes, choose forks to follow your navigation route, navigate around other vehicles and objects, and make left and right turns. You and any authorized driver must remain attentive and use additional caution. This feature does not make the vehicle autonomous. Do not become complacent.

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

Always be aware of road conditions and potential hazards (such as pot holes and speed bumps) and operate the vehicle responsibly.

Arrival Options

• Select an arrival option such as Carpark, Indoor Carpark, Street, Driveway, or Pull Over for Robotaxi-style drop offs.
• Your preferences for arrival options and preferred parking positions are saved for each destination.
• A reasoning model assesses suitable options for your destination and picks an intuitive default.
• The navigation pin is adjusted based on the selected Arrival Option.

Speed Profiles

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

• Driver profile now has a stronger impact on behavior. The more assertive the profile, the higher the max speed.
• The right scroll-wheel up/down now adjusts the Speed Profile setting rather than your precise max speed offset selection in mph or km/h.
• Introduced a new Speed Profile, SLOTH, which uses lower speeds and more conservative lane selection than CHILL.

UI Improvements

• View your Self-Driving stats under Controls > Self-Driving.
• Start Self-Driving with a tap of the touchscreen from Park, or any time during your drive.
• Adjust settings like the Speed Profile and Arrival Options directly from the Self-Driving visualization on the center display.

Brake Confirm

Brake Confirm for the Start Self-Driving button now defaults to off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.

You can enable Brake Confirm in Self-Driving > Brake Confirm.
