The cabin filter's health is displayed as a percentage

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.

NHTSA to Streamline Approvals for Control-Free Vehicles Like Tesla’s Cybercab

In a letter to industry, the National Highway Traffic Safety Administration (NHTSA) has announced that it is overhauling its approvals process for vehicles designed without human controls.

The change addresses a regulatory bottleneck that has slowed down American companies like Tesla from deploying purpose-built Robotaxis, rather than relying on using traditional vehicles with steering wheels and pedals. The policy shift is outlined in a letter posted to the NHTSA’s website, which you can find here.

Reducing Approvals From Years to Months

Under the existing rules today, any vehicle that is built without a steering wheel or brake pedals must receive a special exemption from federal safety standards.

Obtaining exemptions for a particular vehicle was a time-consuming process for both the companies requesting exemptions and the NHTSA. The process was often a black box—nobody knew when an exemption might be granted, and approvals could take years.

The NHTSA, under the new administration’s guidelines for autonomous vehicle development, is now committed to streamlining this process. The agency will be implementing a new, faster approach immediately for receiving exemptions for autonomous vehicles without standard controls. The NHTSA expects decisions on exemption requests to be determined within months rather than years.

Accelerating the Cybercab

This change has massive implications for Tesla, which is banking on the production of the simplified and easy-to-maintain purpose-built Cybercab. The Cybercab is developed from the ground up as an autonomous Robotaxi and will be one of the key beneficiaries of this move by the NHTSA.

Knowing that a final design won't be caught in a multi-year regulatory limbo provides a level of certainty that has been missing. It allows Tesla to confidently plan the manufacturing, development, and deployment processes without worrying whether the project will get stuck in regulatory approvals.

According to the letter, the agency will publish its improved instructions for the streamlined process "shortly." With Tesla already having begun Cybercab pre-production and the goals for its deployment as soon as late 2026, there’s still a lot to be done to make autonomy a part of Tesla’s new sustainable abundance mission statement.

You Can Now Track Tesla’s Robotaxi Deployment

Thanks to Tesla Yoda on X, we have found out that Tesla’s Robotaxi fleet is registered on the Texas Department of Transportation’s public-facing Automated Vehicle Deployment website. This makes the fleet’s movements publicly viewable and trackable, and marks a first for Tesla.

This isn’t just any old FSD test - this is the first officially acknowledged, government-tracked, and sanctioned deployment of a Tesla Model Y operating as a ride-share vehicle. But that’s not all - Texas DOT’s tracker notes that the Tesla does not have a safety driver.

View on the Map

Visitors to the Texas DOT website can filter for “Tesla”, and see, currently, a single active vehicle operating in the Austin Metro area. According to the state’s official data, here’s what we know:

Company: Tesla

Description: Ride-share service

Status in Texas: Testing

Safety Driver: No

The final point is definitely the most interesting here. While Tesla has been testing FSD with safety drivers for some time in Austin and LA for employee-only testing, this is the first time that a vehicle has been officially registered and deployed on public roads without a human behind the wheel for safety.

The fact that there is no safety driver officially shifts the liability from the occupant of the driver’s seat to Tesla, for the first time in a public setting. That’s already pretty significant - we previously dove into how Tesla plans to insure its own vehicles, and potentially owner vehicles in the Robotaxi fleets.

The status currently lists Tesla as “Testing,” confirming that the service isn’t available to the public, but this is expected to change in the coming weeks.

This testing phase is likely part of a short but crucial period that lets Tesla capture data on the safety levels of its current iteration of Unsupervised FSD without a driver supervising. Tesla already stated that they’d be avoiding difficult areas, so this testing can also expose additional areas Tesla may want to avoid, such as school zones or blind driveways.

Tesla will need to prove, both internally and externally, that FSD Unsupervised has the necessary performance to safely navigate the streets without any incidents.

Regulatory Milestone

For years, the concept of a Tesla Robotaxi has been a future promise. Now, it's a present-day reality, albeit in a testing capacity.

Having an official government body list a Tesla as an active, driverless vehicle shows that they’ve been able to clear regulatory hurdles, which Tesla has often pointed to as the issue. It demonstrates a level of confidence from both Tesla and Texas regulators in the system's capabilities.

While it's just a single vehicle for today, we’ll likely see this list slowly expand over time. Alongside being able to track Robotaxi incidents at the City of Austin’s website, we’ll be able to closely watch Tesla’s progress with its first Robotaxi deployments.
