Tesla has made a handful of small changes to its owner’s manuals with the recent holiday update, including a shift to how Autopark works, cabin radar monitoring, and an expansion of certain construction details, among other edits still.
On Monday, Not a Tesla App spotted and reported a handful of the changes seen in Tesla’s owner’s manuals that were not reported in the company’s holiday update release notes. Some of these include subtle feature changes or hints as to what other features may be coming, while many of them simply have different wording than was previously in the manual.
Typically, Tesla will make changes to the owner’s manuals when it debuts new software updates, and although the recent holiday update has offered owners a number of new features, some of those that weren’t reported by the company may be equally important.
You can check out the unlisted updates to the owner’s manual below, complete with new rules for Autopark, the removal of a previously-retired regen braking mode, expansions to certain navigation construction information, and more.
Note: the links navigate to various sections of Tesla’s Model Y owner’s manual, though these updates can be seen across the company’s lineup.
Tesla’s recent changes to the owner’s manual, both big and small
Cabin Radar now used for occupancy, rather than seat sensors
Tesla’s Cabin Radar, located just above the rearview mirror in the latest of the company’s vehicles, is now being used to detect cabin occupancy instead of the individual seat sensors, as was changed earlier this year. Over the summer, Tesla switched from using the seat sensors to using the cabin radar to monitor occupancy, as part of a response to a recall mandating closer passenger and driver monitoring.
The section now also includes a warning that blocking or obstructing the device will disengage Autopilot or Supervised Full Self-Driving (FSD). You can see the entry for cabin radar in Tesla’s owner’s manual here.
Camp Mode: text added to indicate that ports still work
While Tesla has already changed its vehicles so that the USB and 12V ports still work when Camp Mode is engaged, the company has also now updated the owner’s manual text to indicate this. You can see the company’s new details on Camp Mode here, under its section on Operating Climate Controls.
Construction and Accident Alerts to expand
Tesla has been adding additional icons to the map for road closures, accidents, and construction, and while the text in this section previously said they were limited to the U.S., this section has now been removed—suggesting that Tesla could be looking beyond North America with these in the near future.
Not a Tesla App also points out that, in all likelihood, Tesla will just need to wait for more data providers to partner with the company to add this information in other markets than the U.S. and Canada. You can check out this part of the owner’s manual here, in the Maps and Navigation section under the Online Routing section.
Desiccant Bags details removed
Tesla has removed details on its desiccant bag in the heat pump’s A/C section, which previously required a replacement every four years. This could suggest that this service may not be necessary after all, as the hardware likely lasts far more than four years in most cases. You can see the Maintenance Service Intervals section that previously had the instructions here.
Front Camera Window Cleaning
Tesla now points out that owners should clean the inside of the windshield within the front camera housing every so often. This was not previously a required maintenance option, and Tesla now says owners should schedule a service appointment to have the cleaning done when necessary.
There’s also a DIY option for this cleaning, and details for this can be found in the service manual under “Quad Camera Cover – Upper (remove and replace).” You can find the new text for cleaning inside the windshield here in the Maintenance Service Intervals section, listed under Periodic Checks.
Parental Controls now auto-set to these features
Tesla has made the default speed limit setting “Relative” with an offset of plus 5 mph. Additionally, when drivers select “Require Safety Features” in the parental controls, the system now automatically enables the following options, without the ability to change or remove them:
- Automatic Emergency Braking
- Obstacle-Aware Acceleration
- Automatic Blind Spot Camera
- Blind Spot Collision Warning Chime
- Automatic 911 Call
- Allow Mobile Access
- Park Assist Chimes
- Lane Departure Avoidance: Set to Assist.
- Speed Limit Warning: Set to Chime.
- Speed Limit: Set to Relative.
- Offset: Set to +5 mph (8 km/h).
- Forward Collision Warning: Set to Early.
You can find the Safety and Security Settings here, with the above options now located under Parental Controls.
Regenerative Braking options ‘January 2024’ wording removed
While Tesla removed the low regenerative braking setting for new vehicles in January, opting for the higher-efficiency option as default, the company’s owner’s manual has removed a section saying that the low options wouldn’t be available after January 2024. This suggests that Tesla could someday re-introduce multiple regen options in the future in some way, shape, or form.
Tesla’s regenerative braking instructions can be found here, as part of the Braking and Stopping section.
Steering Wheel Weight
Tesla has changed the name of the steering wheel weight option from “Medium” to “Standard,” which you can see here under the Steering Wheel Weight section.
Strikes No Longer Count Against Autopark
Vehicles that include a cabin camera can get as many as five strikes before banning Autopilot features, while those without one can get up to three strikes. However, Tesla has apparently removed the Autopark system from these strike-out rules, meaning that striking out won’t disqualify drivers from the automated park system. You can see Tesla’s Autopark section here.
Valet Mode Privacy Improvements
Tesla has improved the privacy features of its Valet Mode, now preventing access to a handful of features while it is engaged, such as showing text messages even if the owner is still connected to Bluetooth. The vehicle will now also remove home and work address access in this mode, and it will restrict access to driver profiles and a number of other features that could potentially compromise someone’s privacy.
You can check out the Tesla owner’s manual’s section on Valet Mode here, under the larger Driver Profiles section.

Tesla and SpaceX take “Terafab” Trademark fight to Federal Court
Tesla and SpaceX sue a small Illinois firm after cease and desist letters over Terafab.
Tesla and SpaceX are asking a federal judge to rule that their planned Terafab chip factory does not infringe a small Illinois company’s trademark, a request that arrives only after months of quiet negotiation broke down this summer.
The dispute traces to May 18, when Tesla filed three U.S. trademark applications for “Terafab” and “Tesla Terafab,” covering semiconductor chips and related chip making services. TERA-print LLC, a nanotechnology company that has held a federal trademark for “Tera-Fab” since 2021, responded five days later with a cease and desist letter. According to the lawsuit, first reported by Reuters, TERA-print argued that Tesla and SpaceX’s use of “Terafab” would confuse consumers familiar with its own trademark, which covers a desktop photolithography printer sold to researchers for sensor and bioengineering work.
What stands out in the filing is the timing of TERA-print’s own paperwork. One day before sending that cease and desist letter, on May 22, TERA-print applied to expand its existing registration to cover semiconductor materials, silicon chips, nanoelectronic devices and AI design services, categories it had not previously claimed. Tesla and SpaceX call that filing opportunistic in their complaint, noting it arrived two months after Tesla’s public Terafab announcement and just days after Tesla’s own trademark applications went in.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
By June 10, TERA-print was threatening to sue for federal trademark infringement, false designation of origin and unfair competition, the complaint states. Rather than wait to be sued, Tesla, SpaceX and SpaceXAI met with TERA-print six separate times between June and August trying to resolve the dispute directly. Those talks collapsed, and the companies filed for declaratory judgment this week in the U.S. District Court for the Western District of Texas, asking a judge to find that “Terafab” does not infringe TERA-print’s mark before TERA-print can file a claim of its own.
TERA-print isn’t backing down. The company told PCMag it discussed a settlement with Tesla as recently as September 2 and feels misled by what it called Tesla’s professed interest in settling. Its CTO, Andrey Ivankin, said TERA-print holds a Defense Department contract to fabricate semiconductors and partially owns Mattiq Inc., an AI company built on TERA-print’s products, and that the company will vigorously defend its rights.
Tesla and SpaceX argue the overlap is superficial. Terafab is planned as a $16.8 billion complex spanning roughly 100 million square feet at the Grimes County site SpaceX confirmed last month, built to produce chips for Optimus robots, Tesla’s AI computing needs and SpaceX’s orbital data center ambitions, a scale and purpose the companies say no reasonable consumer would confuse with a tabletop lab printer. TERA-print’s product line has stayed focused on lithography tools for biological and sensor research since it registered its mark in 2021.
The trademark fight is the second legal dispute tied to the Terafab project in the past week, following a separate SpaceX suit aimed at keeping company records about the facility out of public view, as KBTX reported. Whether construction proceeds under the Terafab name now depends on a federal judge in Austin.

NHTSA just escalated its Tesla Cybercab investigation in a big way
NHTSA escalated its Cybercab audit into a sworn Special Order with a September 30 deadline.
Federal regulators have moved from asking Tesla questions about its Cybercab to demanding sworn answers. The National Highway Traffic Safety Administration issued a Special Order that requires a Tesla officer to sign an affidavit attesting to the completeness of the company’s responses, with a deadline of September 30.
The order builds on Audit Query AQ26002, which NHTSA opened on September 3, the same day Tesla began commercial Cybercab service in Austin. Teslarati covered that initial inquiry when it surfaced, noting the agency wanted to understand how Tesla certified a vehicle with no permanently attached steering wheel, pedals, or mirrors as compliant with Federal Motor Vehicle Safety Standards. A Special Order is a different tool and converts a fact finding review into a legally enforceable demand, the same mechanism NHTSA used against Tesla in 2023 during its Autopilot investigation.
Several of the 21 requests target a specific gap in Cybercab’s design. One asks whether Tesla used temporarily attached human controls at any point to help certify the vehicle, and if so, which standards depended on that equipment being present. Another quotes an existing rule directly: “The service brakes shall be activated by means of a foot control.” Cybercab has no foot pedal. NHTSA wants a detailed explanation of how the vehicle satisfies that requirement, and how it complies without the kind of exemption granted to Zoox in July under Part 555, the regulatory pathway built for steering wheel free vehicles.
The order does not claim Cybercab is unsafe or that Tesla broke a rule. It requires Tesla to explain, under oath, the reasoning behind decisions the company already made when it self-certified the vehicle. That distinction matters, but so does the exposure. Motor1’s reporting, summarized here, put potential civil penalty exposure as high as $139 million if NHTSA later finds the certification was flawed, on top of whatever criminal risk comes with a false sworn statement.
Tesla has not said publicly how it plans to respond. Cybercab is still carrying passengers in Austin through the Robotaxi app while the September 30 deadline approaches, and the company has continued expanding the vehicle’s footprint even as the regulatory question remains open. The Special Order does not pause any of that and just sets a date by which Tesla has to put its certification logic on the record, with a company officer’s name attached to it.
In a new interview on Wednesday, Tesla uber bull Ron Baron said that anyone looking to buy the company’s stock should do so as soon as they can.
Baron, founder and CEO of Baron Capital and one of Tesla’s most persistent institutional bulls, used a CNBC Squawk Box appearance on Wednesday to deliver a familiar message with fresh urgency: In his opinion, Tesla stock is a buy:
“The time to buy the stock is now. FSD is catching on, and it’s going to be bigger and bigger. 55% of new buyers are buying it (Teslas) with FSD. It’s going to be everywhere. It’s safer.”
The Baron Capital frontman’s case is built around Full Self-Driving. Tesla reported 1.48 million active FSD subscriptions in the second quarter, up 56 percent year over year, and company officials have said roughly 55 percent of new North American deliveries left with a subscription enabled.
Baron framed that attach rate as proof the product is moving from enthusiast extra to default expectation, and as a reason software, not just vehicle volume, should drive the next phase of value.
His conviction on Tesla shares is not theoretical, as Baron Capital made its first Tesla investment in 2014, after years of meetings that began around the 2010 IPO roadshow. The firm later built a large SpaceX position starting in 2017.

Baron said those Musk-led bets have generated about $30 billion of the $71 billion in profits Baron Capital has produced for clients. He put the firm’s current exposure at roughly $25 billion in SpaceX and $5 billion in Tesla. Personally, he described SpaceX as his largest holding, at about $5 billion, with about $1.5 billion in Tesla and additional Tesla exposure through the firm’s funds.
That concentration is also a statement of loyalty. Asked about talk of a SpaceX-Tesla combination, Baron said he had already walked Elon Musk through arguments for and against a deal, then declined to repeat them on air. His public position was simpler: “Whatever you decide is better is what I’m going to support,” he said to Musk.
Baron also said that he picked up the farewell edition of the Model S after Tesla decided to sunset the vehicle earlier this year, calling it his favorite car he’s ever driven.
