Update 2026.27.5 (FSD 14.3.9) - Release Notes

Automatic Collision Evasion activates Full Self-Driving (Supervised) to try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:

- Scenario 1: A frontal collision is imminent and braking alone may not avoid it.

- Scenario 2: Your vehicle 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) v14.3.9 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.

Sob a sua supervisão, a Condução Autónoma Total (supervisionada) pode conduzir o seu Tesla para praticamente qualquer local. Inicia a partir de uma posição de estacionamento, efetua mudanças de faixa, seleciona forquilhas para seguir a sua rota de navegação, navega em torno de outros veículos e objetos, efetua curvas para a esquerda e direita e estaciona no seu destino. Você e qualquer pessoa que autorize devem ter cuidado adicional e permanecer atentos. Não torna o seu veículo autónomo. Não se acomode.

A Condução Autónoma Total (supervisionada) está ativada no seu veículo. Para utilizar a funcionalidade, prima o botão para Iniciar a Condução Autónoma na interface do utilizador ou prima o botão da roda de deslocação direita uma vez. Pode desativar a Condução Autónoma Total (Supervisionada) nas Definições do Autopilot.
