Tesla is preparing to take a massive step forward in one of its most important markets. Recent updates to the Tesla Model 3 and Model Y Owner's Manuals in China suggest that the automaker is finally ready to roll out its latest Full Self-Driving (FSD) technology, version 14, to Chinese drivers. This move comes as Tesla is enjoying a major sales surge from Giga Shanghai, providing the perfect momentum for a software-driven relaunch.
Introducing Tesla Assisted Driving (TAD)
One of the most interesting details found in the updated manual is a change in branding. In China, it appears that FSD v14 will officially be referred to as "Tesla Assisted Driving” (let’s call it “TAD,” shall we?). This shift away from the "Full Self-Driving" name isn't entirely new for the region; when Tesla first debuted the technology in the country, it used the name "Urban Road Autopilot Assistance."
The updated Chinese manual describes several new features exclusive to FSD v14. Specifically, one new section highlights different speed profiles that drivers can choose from. Speed profiles give drivers more control over how the AI "personality" behaves on the road. These include "Standard," "Hurry," and the much-discussed “Mad Max” and "Sloth" modes. For those unfamiliar, Sloth mode allows the vehicle to drive slightly below the speed limit to prioritize a more cautious and comfortable ride, and it came out with FSD v14.1 last fall.
The Technical Leap of v14
FSD v14 represents a significant jump in capability compared to the software currently available in China. While it doesn't yet feature the 10-billion-parameter model that Tesla has delayed to FSD v15, version 14 is already built on a 1-billion-parameter architecture. Tesla CEO Elon Musk has frequently stated that FSD v14 is already "much safer than a human," and the goal is to make it orders of magnitude safer over time.
One of the standout improvements in the latest v14.3.2 iteration is the unification of various AI models. Tesla has synced the brains behind FSD, Actually Smart Summon (ASS), and the Robotaxi platform. This means that features like Summon are becoming more reliable and smarter, as they leverage the same high-level logic used for complex street navigation.

Navigating Local Data Laws
The road to this update has been a long one for Tesla China. While the company briefly launched FSD v13 to a small group of Hardware 4 (HW4) owners, local data regulations have consistently hindered a full-scale rollout. To solve this, Tesla established a dedicated local AI training center earlier this year, ensuring that Chinese driving data is processed within the country’s borders.
It remains to be seen if v14 will be the version that finally clears all regulatory hurdles for a mass-market launch. Tesla is also working on "FSD v14 Lite" for older Hardware 3 vehicles, which is expected to expand internationally later this summer. If TAD (FSD v14) launches successfully in China, it would be a big win for the company, effectively proving that its vision-based system can handle the unique and dense traffic patterns of Chinese megacities.
Whether it’s called FSD, TAD, or just "Self-Driving," the goal is the same: providing a safer, more convenient driving experience. With the owner's manual already updated, it's likely only a matter of weeks before the first Chinese testers get to see Sloth mode and other v14 goodness on their Tesla vehicles.
