If your Tesla is not recognizing objects correctly, if it appears to be performing abnormally, or if you're receiving errors related to your cameras or Autopilot, you may want to calibrate your vehicle's cameras.
The process may take a while to complete, but it's quick and easy to begin.
The cabin camera does not directly impact Autopilot’s performance while engaged. Instead, it’s solely used to help monitor the driver and confirm that they're paying attention while Autopilot is engaged.
Tesla initially equipped its vehicles with ultrasonic sensors, but the Austin-based automotive company is transitioning its vehicles to leverage Tesla Vision exclusively. In 2022 Tesla begin to omit ultrasonic sensors entirely and now uses the vehicle’s cameras exclusively.
How to Calibrate Your Tesla’s Cameras
To calibrate your vehicle's cameras, follow the steps below. Keep in mind that although you can drive your vehicle immediately after performing these steps, some features that depend on the vehicle's cameras will not be available until after calibration is completed.
Go to “Controls” (the car icon)
Tap “Service”
Tap “Camera Calibration”
Once you’ve tapped “Camera Calibration,” a warning message will pop up with the following text:
“Clearing the Autopilot camera calibration will reset the calibrated camera positions and angles stored on the Autopilot computer. This procedure should only be performed if the cameras have been moved due to a windshield or camera replacement. Clearing calibration will result in no Autopilot features until the system recalibrates, which may take up to 100 miles of driving on roads with highly-visible lane lines.”
When you’re ready, tap “Clear Calibration.”
Note: If possible, drive on a long straight road with multiple lanes (like a controlled-access highway) with easily visible lane markings for quicker and more accurate calibration. According to Tesla, “Clear Calibration may not resolve all camera and sensor concerns.”
How Long Does It Take to Calibrate the Cameras?

Not a Tesla App
First, you will not be able to use Full Self-Driving, Enhanced Autopilot, or Basic Autopilot. These will all be disabled while the cameras are recalibrated.
The steering wheel icon that previously showed whether Autopilot was engaged will now show a blue ring. As the vehicle gathers data and the software adjusts, the ring will adjust to show the calibration progress. Although it may take up to 100 miles of driving to calibrate your cameras, it's usually much quicker. To be safe, you should plan for the calibration process to take 2-3 hours of driving to complete.
Camera Calibration Stuck at 99%
The ring may get to 99% complete and then get 'stuck.' This is normal. Be patient and allow the car to complete the process. It will resolve itself and the vehicle will notify you when calibration is complete.
If after a few drives and more than 100 miles the recalibration is still stuck, contact Tesla to set up a service appointment. They’ll be able to determine whether the issue is software or hardware-related. Tesla may be able to diagnose your vehicle remotely and push an update to help fix any issues.
Why Do Cameras Need to be Calibrated?
The cameras placed strategically around the vehicle need to be aligned perfectly in order to function properly. Each video feed from the cameras is joined together to form a 360-degree view of the vehicle’s environment. If there's a gap between cameras or an extension overlap, it could cause the vehicle to not see certain areas or see "double." It’s like taking multiple pictures with your phone and then stitching them together. It’s how astronomers edit and stitch pictures together from the James Webb Space Telescope.
The calibration process doesn't actually move the cameras, but instead, it crops and adjusts each camera's feed so that the vehicle sees a single unified image. That’s why the slightest millimeter of miscalibration could cause issues.
What Does Recalibrating Tesla’s Cameras Fix?
Recalibrating the cameras in your Tesla may fix a number of things, including phantom braking, inability to properly detect surrounding objects, Autopilot faults, and various error messages.
Tesla states in their Model 3 instruction manual that a few limitations may cause Autopilot’s functionality to be limited. They include:
Poor visibility (due to heavy rain, snow, fog, etc.).
Bright light (due to oncoming headlights, direct sunlight, etc.).
Damage or obstructions caused by mud, ice, snow, etc.
Interference or obstruction by object(s) mounted onto the vehicle (such as a bike rack).
Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
Narrow or winding roads.
A damaged or misaligned body panel.
Use of gray or aftermarket glass.
Interference from other equipment that generates ultrasonic waves.
Extremely hot or cold temperatures.
If you've just received delivery of your Tesla, your vehicle may still be calibrating its cameras. Look for the blue ring around the Autopilot icon to see if your vehicle is still calibrating its cameras.
Hopefully, after recalibrating your cameras, the issues you were experiencing are fixed. Although recalibrating your cameras does not fix all issues, it's usually a good first step to try.
As always, if you continue to experience issues, you should schedule an appointment with Tesla service through the Tesla app.

In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
