The cabin filter's health is displayed as a percentage
CheekyTesla
Tesla’s Service Mode is a feature that allows both users and technicians to diagnose and view vehicle information. With a recent update, you can now view the health of your vehicle’s cabin filter and Bio-Weapon Defense Mode’s HEPA filter.
Cabin Filter Health
To view your vehicle’s cabin filter health data, you’ll need to enable Service Mode. You can follow our guide on how to access Service Mode if you’re not familiar with it.
After enabling Service Mode you’ll want to navigate to the HVAC section. Here you’ll find a view of your vehicle’s entire HVAC system including a health meter for your cabin filter and HEPA filter (if equipped). The health readout is shown as a percentage of health, with a lower number indicating that the cabin filter needs to be replaced. However, we’ve also seen some users report they had a value over 100%. The health meter is intended to provide an approximation of the useful life of your Cabin Air filter.
Tesla likely approximates the health of the cabin filter based on the filter's age and how many hours the HVAC system has been used. It may also consider the fan speed of the HVAC system to account for higher airflow through the filter.
If you have an Intel-powered infotainment unit (~2021 and older), you may not see the HVAC image displayed above, instead, you’ll see one like the image below, which will show you your cabin filter health near the top of the screen.

When to Replace
In general, Tesla recommends replacing the Cabin Air Filter every 2 years, and that the HEPA filter, for vehicles with access to Bio-Weapon Defence Mode, be replaced every 3 years, but this can vary depending on usage and the amount of debris going into the cabin.
Tesla is one of the few manufacturers, if not the only one, that continuously runs air through the cabin filter, even if you’re recirculating air from inside the vehicle. Most other vehicles will only run air through the cabin filter when it’s coming from outside. This helps the air inside the vehicle to become cleaner as it continues to be filtered.
How to Replace
The Cabin and HEPA Air filter replacement procedure is straightforward and could be a DIY task. Tesla provides instructions on a model-by-model basis on how to replace them, but in general, the basic steps are below.
The filter replacements can differ based on model year as well. High-voltage connections are also passing through the HVAC module, so extra caution is needed. We recommend reading your vehicle’s specific instructions before proceeding. They will advise against touching any electrical connections.
Basic Replacement Instructions
1. Turn off Climate Control
2. Remove the passenger-side floor mat and move the seat fully back.
3. Use a pry tool to release the clips that hold the right-side front footwell cover to the instrument panel, and then disconnect the two electrical connectors inside.
4. Working from top-to-bottom, use a trim tool to release the right-side panel from the center console.
5. A single T20 screw secures the cabin filter cover, remove the screw and cover.
6. Fold the 2 tabs securing the filter away, and then pull the upper and lower filters out.
7. Ensure that the arrows on the new filters face towards the rear of the vehicle, and install them.
8. Proceed through steps 6-1 in reverse to reassemble.
Once again, these steps vary by vehicle configuration, model year, and do not apply to legacy vehicles without a heat pump.

MotorTrend is running their suite of Best Tech of 2025 - and the winner that took home the Best Tech for Public Charging System is none other than Tesla’s North American Charging Standard - better known as NACS or the Tesla Plug.
What is NACS?
NACS is Tesla’s home-grown connector standard - and is now the standard in North America. Tesla opened the connector standard back in November 2022, inviting other automakers to collaborate on a better and easier-to-use charging standard.
At that time, CCS was rapidly gaining traction as the industry standard, but Teslas remained the most common EV on the road. This put Tesla in a unique position to establish a new standard in North America, where the Tesla connector was the most popular.
SAE Standard
After Tesla opened up its connector, the Society of Automotive Engineers (SAE) swiftly adopted it, naming it the J3400 EV Coupler. The SAE initiated the process in June 2023, with the validation phase concluding in October, alongside the release of the J3400 Recommended Practices document, officially establishing NACS as the industry standard in North America.
While a few holdouts, such as Volkswagen and Stellantis, initially hesitated to embrace NACS, they soon came on board. Today, no major automaker selling vehicles in North America plans to use CCS for their future EVs.
Why is NACS Better?
NACS is an innovative charging standard that outperforms both CCS1 and CCS2 (the EU’s version) in almost every way. The system is lighter, more user-friendly, and more versatile, offering better thermal efficiency than comparable CCS systems. Additionally, the handle and plug are designed to be more ergonomic and streamlined, making them easier to use and far less cumbersome.
Differences Between CCS1 and CCS2
The CCS1 charging standard in North America combines the J1772 connector for AC charging with separate pins for DC fast charging. However, it differs drastically from CCS2, which is used in Europe. CCS2 features a more compact design and allows digital communication for both AC and DC charging. It also supports higher power than CCS1.
Technically Better
NACS was designed out of necessity back in 2012 when there wasn’t a connector that met Tesla’s needs for the original Model S. As it turns out, it remains far superior to the charging standards created by legacy automakers today, who were more concerned with having a simple plug-in port than the efficiency and quality of the charging process itself.
Unlike CCS1 or J1772, which use analog communication when charging over AC power, NACS relies on digital communication, regardless of whether it’s charging the vehicle over AC or DC power. This enables better and more reliable information exchange during the charging process. In contrast, analog systems like CCS1 can run into issues—such as ground faults—that may leave your EV bricked without an explanation since data isn’t transmitted the same way.
With NACS, however, any issues can be diagnosed on either the vehicle side or the Supercharger side. If you’re interested - open up Service Mode while plugged into your Wall or Mobile Connector, or while at a Supercharger - and take a peek at the Charging Pane.
Ultimately, NACS offers improved diagnostics and testing, a more intuitive cable and interface, and the best part is that it can support up to 1,000V charging without major changes. Plus, it works seamlessly with both residential two-phase and commercial three-phase power without requiring major alterations to the connector format—unlike CCS1 and CCS2, which uses separate connectors for AC and DC charging.
Improved Communications
We’ve already discussed how digital communication enables effective debugging, but it also plays a crucial role in streamlining the payment process for charging. This is how Tesla makes its Supercharging experience so effortless. When you plug in your vehicle, it communicates directly with the Supercharger and Tesla’s servers. Your payment is automatically processed through the payment method linked to your Tesla profile, making the entire process seamless.
In contrast, with most CCS1 chargers, the process is the reverse. While Plug-and-Charge is a standard, it’s not always fully or reliably implemented. When you arrive at a CCS1 charger, you often need to plug in your EV, fumble with an app or the screen and hope the charging post is working properly before you can proceed.
Here’s a list of automakers that have either pledged to begin using NACS - usually by their 2025 or 2026 model year - or have already incorporated it. Many of these companies also offer adapters, and can also use Tesla’s Magic Dock-equipped Superchargers.
Any companies in parentheses represent a sub-brand of the parent company that has also committed to the NACS connector.
And that’s it—NACS has won the EV charging standards race in North America. If you’re in Europe, you’re using the CCS2 connector, which is superior to the CCS1 connector offered in North America. China has its own relatively novel connector standard, but it still differentiates between DC and AC plugs, unlike NACS, which keeps things simpler.
Tesla’s autonomous robotaxi made a big impact last year at the We, Robot event in October, sparking plenty of questions about when, where, and how production would begin. Well, it looks like we finally have some answers to these questions thanks to new Cybercab-related job openings.
Engineering Roles
Tesla is actively recruiting engineers to focus on various aspects of the Cybercab’s production. One of the key positions is for an equipment engineer, responsible for developing the machinery that will be used to build the Cybercab. Designing and implementing the assembly line is crucial, especially with Tesla’s ambition to manufacture thousands of Cybercabs in the near future.
Unboxed Production Process
Tesla plans to produce the Cybercab using its revolutionary “unboxed” process, which stands in stark contrast to traditional car manufacturing methods. Unlike typical assembly lines that build vehicles from the floor up, the unboxed process involves constructing vehicle sections in parallel and bringing those parts together for final assembly. This method increases the number of engineers that can work on the vehicle at once and increases accessibility for works and robots, allowing the vehicle to be manufactured more efficiently.
Tesla shows off the unboxed process in the vehicle below:

A crucial part of the Cybercab’s production will be handled by a new process engineer specializing in plastics. This engineer will focus on the exterior plastic panels, working alongside a tool & die specialist. The reason for this specialized role is likely due to the Cybercab’s unique use of paint-impregnated plastic for its exterior panels, which requires different processes and tooling than Tesla’s typical vehicle exteriors.
Tesla’s VP of Vehicle Engineering, Lars Moravy, shared that the company will be injecting polyurethane paint directly into the plastic during the manufacturing process. This method eliminates the need for a traditional paint shop, as the colors are embedded directly into the plastic while the panels are molded. The best part is that these panels are highly resilient—if they get scratched, dinged, or worn down, the original color remains visible throughout, unlike standard painted panels, which would reveal the underlying material.
Technicians
To implement these new engineering practices, Tesla is also hiring various technicians for the assembly line. These include specialists in plastics, general assembly, and the Giga Press, all of whom will play key roles in bringing the Cybercab to life.
According to the Q4 2024 Earnings Call, the Cybercab’s assembly line is not expected to launch until late 2025 or early 2026. Building such an innovative assembly line is no small feat, and it’s clear Tesla is laying the groundwork for something special.
