You can find the defrost button in the climate menu
Not a Tesla App
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
One of the best parts of owning an EV is preheating the cabin before you get in
Not a 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
Tap and hold any icon to customize the bottom row of apps
Not a Tesla App
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
You can add a fifth favorite icon to the Tesla app
Not a Tesla App
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’s Dan W Priestley attended the Advanced Clean Transportation (ACT) Expo in Anaheim, California, and provided an update on Tesla’s Semi truck program. The presentation covered several key developments on the status of Tesla’s Nevada Semi Factory, refinements to the Semi, and Tesla’s plans for charging and ramping production through 2026.
Let’s dig in and take a look at everything that was captured by the Out of Spec team at ACT Expo. The original video is embedded below if you’d like to watch it.
Semi Factory & Production Ramp
Priestley reaffirmed the timelines mentioned during Tesla’s Q4 2024 Earnings Call that Tesla will scale Semi production in 2026. To achieve this, Tesla has been actively building and expanding the Gigafactory Nevada site, specifically to support the production of the Tesla Semi. The dedicated Semi facility will have a targeted annual capacity of 50,000 Semi trucks.
Following the beginning of production, Tesla will utilize the initial trucks to integrate into its own logistics operations. This will serve as both a final real-world testing ground as well as an opportunity for Tesla to gather data internally. Tesla plans to begin subsequent customer deliveries throughout 2026 as the ramp-up continues.
Reuters also reported that Tesla is hiring over 1,000 new employees at the Semi Factory to begin the rapid ramping of the program.
Semi has already amassed 7.9 million miles with Tesla’s current testing and operational fleets, providing some real-world data and testing. Feedback for the truck has been exceptionally successful, with many drivers praising the Semi’s performance and comfort.
New Tesla Semi Features
Of course, it wouldn’t be a Tesla keynote without showing off some new things. The Semi will be available in 500-mile and 300-mile range configurations, now featuring updated mirror designs and a drop-down glass section to improve visibility and allow easier interaction with external elements—such as control panels at ports, for example.
New Electric Power Take-Off (e-PTO)
The Tesla Semi will also feature a new capability called Electric Power Take-Off, or e-PTO system. Similar to the PTO systems found on other vehicles, this will allow the Semi’s high-voltage battery to power auxiliary equipment at variable voltages. That includes being able to power things like climate-controlled reefer trailers, potentially replacing the noisy and polluting diesel generators traditionally used for this purpose.
Charging and Batteries

Tesla is also working on an updated battery pack design for the final production design of the Semi. This new pack is designed to be more cost-effective to manufacture. The battery pack itself is slightly smaller than before, but the truck maintains the same level of range through efficiencies. Dan also confirmed during his keynote that the battery cells for the Semi will be sourced domestically inside the United States, helping to alleviate potential burdens due to tariffs.
On the charging front, Tesla is using MCS - the Megawatt Charging System - capable of 1.2MW - and designed specifically for Semi. The system uses the same V4 charging hardware found at Supercharger sites but focuses on that larger power output. Alongside a smaller physical footprint, Tesla will be able to configure these V4 cabinets for either dedicated Semi charging or for shared power scenarios with regular Superchargers. Tesla is also working on an integrated overnight charging product, but Tesla isn’t ready to talk about it yet.
46 Semi Charger Sites Coming

Finally, Tesla has made substantial investments in a public charging network for the Semi. There are currently 46 sites in progress throughout the United States, and plans for significant expansion throughout 2026 and 2027. These sites are strategically located alongside major truck routes and within industrial areas to support long-haul and regional operations. Tesla is aiming to offer the lowest possible energy costs to operators to help incentivize adoption.
This was one of the best updates to the Tesla Semi we’ve received since its initial unveiling. It seems that the Semi will receive a big portion of Tesla’s attention in 2026, while Robotaxi and FSD Unsupervised take the stage this year.
The Tesla Semi has the potential to transform transportation even more dramatically than EVs already have, serving as a testament to Tesla’s mission to electrify the world.
Sentry Mode is an invaluable tool for owners - capable of keeping the vehicle safe and secure even when you’re not around. This is especially true in recent times, with the misguided and unfortunate incidents surrounding Tesla ownership, including damage to Tesla vehicles, showrooms, and Superchargers.
B-pillar Camera Recording and Dashcam Viewer
With the 2025 Spring Update on 2025.14, Tesla is expanding Sentry Mode’s functionality for certain vehicles with some much-needed changes. Sentry Mode and Dashcam can now record footage from the vehicle’s B-pillar cameras. These cameras are located on the side pillars of the vehicle, between the front and rear doors.
This adds two crucially needed viewpoints, making Tesla’s Sentry Mode a truly 360-degree security system. These cameras also provide the best angles for capturing license plates when parked, so they will be greatly appreciated by owners in the event of an incident.
These vehicles are also receiving an improved Dashcam Viewer, which now displays the six camera feeds along the bottom and a new grid view. It also allows users to jump back or forward in the video in 15-second increments.
However, to the disappointment of many owners, not all vehicles are receiving these updates due to the additional processing power needed.
Limited to Hardware 4 Vehicles, Ryzen Isn’t Enough
We have confirmed that Tesla is only adding the additional camera recording and improved Dashcam Viewer on hardware 4 (HW4 / AI4) vehicles. The newer hardware presumably has the additional processing power and bandwidth needed to handle recording and saving the two additional video streams during Sentry Mode and Dashcam.
For the time being, owners of HW3 vehicles are not receiving this feature. This includes all vehicles with HW3, even those with AMD Ryzen infotainment systems. If you’re not sure whether your vehicle has HW3 or HW4, you can refer to our FSD hardware guide.
While there’s no doubt that recording two additional camera streams would be more computationally intensive, we hope that Tesla adds the improved Dashcam Viewer to HW3 vehicles in a future update.
Cybertruck Also Missing Improved Sentry Mode
Surprisingly, and most confusing for many - is the fact that the Cybertruck is also not receiving the improved Dashcam Viewer and B-pillar camera recording with this update. This struck us as odd, especially since the Cybertruck is currently the only vehicle with the improved, more efficient version of Sentry Mode.
Every Cybertruck is equipped with HW4 and AMD Ryzen infotainment units, so this clearly isn’t a hardware restriction. It’s possible the more efficient Sentry Mode is playing a role here due to the infrastructure changes. However, we expect Tesla to address this in a future update and eventually release these features for the Cybertruck as well.
Given the Cybertruck’s high visibility and its status as a frequent target for both positive and negative attention, many owners hoped that the Cybertruck would be one of the vehicles to receive this feature.
Adaptive Headlights
Tesla finally started rolling out its adaptive headlights in North America. While the new Model Y already came with the feature when it was released last month, other vehicles with matrix headlights are now receiving the feature in the Spring Update.
All vehicles with matrix headlights are receiving this feature, which includes the new and old Model 3, first-gen Model Y, and the new Model S and Model X.
If you’re not sure if your vehicle includes matrix headlights, check out our guide. What’s interesting here is that older vehicles that were retrofitted with matrix headlights due to an accident or user replacement are also receiving the adaptive headlights feature.
Legacy Model S & Model X
As with most updates, the older legacy Model S and Model X are not receiving all the features included in this update. Unfortunately, some of the features, which include the Blind Spot Camera on the instrument cluster, Save Trunk Height Based on Location and Keep Accessory Power On are limited to the new Model S and X.
Legacy S and X models will receive the Alternative Trip Plans feature, Avoid Highways (Requires Intel MCU) and the Keyboard Languages feature.
These vehicles are also receiving all the features in the Minor Updates section except for the visualization showing how far the door is opened, which is exclusive to the Cybertruck. These additions include improved music search results, contact photos in the phone app, automatic connecting to hotspots, the ability to show third-party chargers, view Supercharger amenities, and various improvements to music services.
While many users will be disappointed not to receive the B-pillar camera recording and Dashcam Viewer improvements, it’s important to remember that Tesla typically does a great job at bringing features to older vehicles, at least with the Model 3 and Model Y. If a feature isn’t added, it’s usually due to a hardware limitation.
