Like most vehicles, dealing with snow and ice on your Tesla can be challenging, especially during the colder months. Here are some essential winter tips and techniques to defrost your car and ensure your vehicle is ready for a safe drive.

Defrost From The Tesla App

Before you even get to your vehicle, it's a great idea to preheat the cabin and turn on the defroster. Your Tesla's cabin will warm up extremely quickly thanks to a dedicated heater. Unlike internal combustion vehicles, the engine doesn't need to warm up before the vehicle starts producing heat. Teslas will start warming up immediately and it often only takes a few minutes to warm up the cabin to a comfortable temperature.

To start the climate system from the Tesla app, just tap the Fan icon directly underneath the vehicle. Those icons can be customized as well (see more below). Alternatively, you can scroll down to the Climate section and activate the climate system from there.

To start defrosting your vehicle, you can also add the Defrost icon to the quick actions icons underneath the vehicle model, or you can go into the Climate section.

Simply slide up the panel at the bottom of the screen to reveal additional options, which include Defrost Car, Bioweapon Defense Mode (if equipped), Camp Mode, and Dog Mode.

Tesla Defrost Button

Finding the defrost buttons in the vehicle is a little less obvious, and an area that Tesla can improve. However, it's crucial to use them if snow is building up on your windshield while driving.

To activate the front windshield defroster tap on the climate temperature at the bottom of the screen, then tap on the curved "Defrost" icon twice. The icon is placed to the right of the 'Auto' button on the climate screen.

Tapping the button once will activate the 'Defog' function and turn the icon blue. You'll want to tap it again so that it turns red and the vehicle starts aiming heat toward the windshield.

To start the rear defroster, tap on the rectangular defrost icon next to the AC icon. Unlike the front defroster, the rear defroster only has a heat option.

Differences Between Defrost Button In the App and the Car

The defrost button in the app works slightly differently than the button in the vehicle. When activating the defrost option in the app, the vehicle will turn on the front and rear defrosters, as well as set the cabin temperature to the max, whereas in the vehicle, the front defrost button will only turn on the front defroster.

There is currently no way to turn on the front defogger from the app, but you can manually activate the climate system with a lower temperature to help defog the vehicle.

Turn On Heated Mirrors

All Tesla models include heated mirrors, but there isn't a separate button to activate them. Instead, to turn on your heated mirrors, you'll want to activate the rear defroster, which will automatically activate both the rear defrost and your heated mirrors.

Defrost Charge Port

The charge port heater is also activated when you turn on the rear defrost button in the vehicle or when you activate defrost from the Tesla app.

Customize Vehicle's App Icons

For quicker access to the vehicle's defrost buttons, you can add them to the row of icons at the bottom of the screen.

To customize the apps that appear along the bottom, simply tap and hold one of the icons until the 'All Apps' menu shows up with all available apps.

You can then drag the defrost button or any others to the bottom bar. Tap 'Done' above the apps menu to exit the customization mode.

Customize Tesla App Quick Actions

Similar to adding the Defrost icon to your vehicle's bottom bar, you can tap and hold any of the icons underneath your vehicle's 3D model to customize which options you want to have quick access to.

After tapping and holding any of the icons, you'll be presented with a table of available options. You can then drag any items to the quick access area.

Although Tesla defaults to only showing four favorite actions, you can squeeze in a fifth icon. Just follow our steps in 'How to Add a Fifth App Icon.'

Clearing Snow & Ice

If you preheated your vehicle, snow should be fairly easy to remove from the top of your vehicle. Thanks to the glass roof in most Teslas, the vehicle may have melted most of the snow off the top of the vehicle for you.

Use a soft brush or snow scraper to gently remove any remaining snow from the windshield, rear window, side mirrors, and lights. Avoid using hot water, as it can crack your windows.

Understanding how to defrost your Tesla and customize its settings ensures a safe and comfortable drive during some of the most crucial drives. Being able to remotely defrost or warm up your vehicle, even if it's in an enclosed area is easily one of the best parts of owning an EV. Take advantage of it and stay warm!

Tesla Adds New Anti-Theft Protection for Supercharger Cables

By Karan Singh
Not a Tesla App

Tesla has begun installing a new set of anti-theft measures on some Supercharger cables. This is a two-part process, and includes an exterior-wrap called DyeDefender, as well as engravings on the actual copper of the Supercharger cables themselves.

Superchargers, just like other high-speed electric vehicle charging stations, have been consistently subject to both vandalism and theft. While vandalism is something that can be reduced by increasing policing and security in the area, theft is a different beast to tackle. 

Thieves are usually after the copper inside the charging cable - which is densely packed and valuable when taken to a scrap yard. So how is Tesla tackling this?

DyeDefender

First up is a field trial of a product called DyeDefender. You can find this product online to secure ICE catalytic convertors, but the overall premise is fairly simple. A pressurized staining dye is housed inside a stainless steel hose, which is laid overtop or around the object you need to protect - in this case, the Supercharger cable.

The stainless steel cable itself is called CatStrap - and is extremely difficult to cut through. If you do manage to cut through, the dye squirts out, coloring you blue quickly. The dye itself is harmless, but helps to identify potential thieves. Tesla’s Head of Charging - Max de Zegher, confirmed that this is only a trial rollout - instead, Tesla is considering another alternative.

Tesla has begun installing new anti-theft measures on some Supercharger cables, consisting of an exterior wrap called DyeDefender and engravings on the copper wiring inside the cables.

Like other high-speed EV charging stations, Superchargers have been frequent targets of vandalism and theft. While vandalism can often be mitigated through increased security, theft presents a bigger challenge. Thieves primarily target the copper inside the charging cables, which is densely packed and valuable as scrap metal.

DyeDefender

To address this, Tesla is trialing DyeDefender, a theft deterrent system commonly used to protect catalytic converters. It consists of a pressurized staining dye housed within a stainless steel hose called CatStrap, which wraps around the Supercharger cable. The CatStrap is highly resistant to cutting, but if breached, it releases a bright blue dye. While harmless, the dye is difficult to remove, making it easier to identify suspects.

In addition to DyeDefender, Tesla is also engraving the actual copper wiring inside the cables, making stolen material harder to sell since scrapyards often reject marked metals.

Engraved Cables

This alternative is more scalable, more cost effective, and doesn’t impact service operations or the customer experience - and its simply engraving the copper inside the cables. Superchargers cables will state “Property of Tesla” on them - engraved right into the cable from the factory in Buffalo, New York.

Recycling companies and scrap yards will see that the cables belong to Tesla - and won’t accept them. Instead, they’ll reach out to Tesla to inform them that they have received stolen goods. While that may not have an impact immediately - as thieves learn that the copper they steal from Superchargers is worthless and could risk them getting in trouble, they’ll be less likely to go ahead and try.

It is definitely interesting to see Tesla try out some rather unique options to keep Supercharger sites safe and functional. Tesla will likely focus the deployment of DyeDefender in areas that experience continual theft - but again, this is only a trial. The impact of cable engraving will likely take some time, but it’ll pay off in the long run.

Until then, make sure to keep reporting any downed Supercharger sites. You can do that in the Tesla App through Location > Charging >Select Site > Report an Issue. If you have any other neat ideas on how Tesla can stop vandalism and theft, let us know in the comments or in the forums!

This solution is more scalable, cost-effective, and doesn’t disrupt service operations or the customer experience—it simply involves engraving the copper inside the cables. Supercharger cables will be permanently marked with “Property of Tesla Motors,” engraved directly at the factory in Buffalo, New York.

Recycling companies and scrap yards will immediately recognize that the cables belong to Tesla and refuse to accept them. Instead, they may notify Tesla that they’ve received stolen goods. While this may not have an immediate impact, over time, as thieves realize that stolen Supercharger copper is unsellable and could get them caught, they’ll be less inclined to target them.

It’s interesting to see Tesla experiment with unique ways to protect Supercharger sites. While the company will likely focus on DyeDefender deployments in high-theft areas, this remains a trial phase. The full impact of cable engraving may take time to materialize, but it should prove effective in the long run.

In the meantime, continue reporting any downed Supercharger sites through the Tesla app by navigating to Location > Charging > Select Site > Report an Issue.

Tesla Activates In-Cabin Radar in Software Update 2025.2.6

By Not a Tesla App Staff
Not a Tesla App

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.

Why Not Vision?

Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.

What Tesla Announced

Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.

Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.

New Feature in Update 2025.2.6

Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.

In the release notes, Tesla describes the update as:

“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”

For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.

Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.

Supported Models

Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.

The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.

At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.

We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.
