Update 2026.2.9.6 (FSD 14.3) - Release Notes

Full Self-Driving (Supervised) v14.3 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.

Upcoming Improvements:

- Expand reasoning to all behaviors beyond destination handling.

- Add pothole avoidance.

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

お客様の監視の下、フルセルフドライビング（スーパーバイズド）は、お客様のTeslaをほぼどこへでも運転することができます。駐車した位置から起動し、車線変更、ナビゲーション ルートに合わせた分岐の選択、他の車両や障害物の回避、および左折や右折を行い、目的地に到着すると駐車します。お客様およびこれの使用を承認される方は、充分に注意を払い、周囲を確認しながら使用する必要があります。この機能はお客様の車両を自律運転させるものではありません。注意力散漫な状態で運転しないでください。

車両は、フルセルフドライビング（スーパーバイズド）が有効になっています。この機能を使用するには、UI の「セルフドライビングを開始」ボタンを押すか、右スクロール ホイール ボタンを 1 回押します。オートパイロット設定でフルセルフドライビング（スーパーバイズド）を無効にすることができます。

If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) the blind spot indicator light flashes, a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.

To go along with some of the naming changes, Tesla is replacing the term Autopilot with Self-Driving in most areas.

- Under Controls, the Autopilot tab has been renamed Self-Driving.

- Under the Autopilot menu, “Autopilot Features” has been renamed “Self-Driving Features.” This lets the user select between TACC, Autosteer, or Full Self-Driving.

Tesla has changed the way the map version appears in the Software menu. Instead of listing the full map version, which includes the region, version, and build, Tesla will now include only the region and version, such as NA-2025.44.

Tesla added 3D Supercharger Site maps in the 2025 Holiday Update. While the holiday update included 18 Supercharger sites in the United States, Tesla is now expanding this to Europe. We found at least two new Supercharger site maps in Belgium, located in Brugge and Heusden-Zolder.

These 3D representations of a Supercharger site include an accurate layout of the site, which is then coupled with live data.

The layout shows where each spot is, the location of the charger relative to the parking spot, handicap- and trailer-friendly stalls, and more.

The live data is even more interesting. Not only does it show which spots are occupied, but it also shows which Tesla model is charging at each location. It’ll identify and display a 3D model of the vehicle, and for non-Tesla EVs, it’ll display a generic vehicle model.

While these 3D models are limited to vehicles with AMD Ryzen infotainment units, anyone can view them by searching for the location in maps.

ECU Update Status Panel Updates - Non-CAN ECUs Added

The ECU Update Status panel now includes non-Controller Area Network (CAN) Electronic Control Units (ECUs), such as the Autopilot processors and Telematics Control Unit (TCU).

Models: Model S (2021+), Model 3, Model X (2021+), Model Y, Cybertruck
