Tesla owners who are dog lovers no longer have to decide between Sentry Mode and Dog Mode. That is just one of several enhancements in the latest update — 2022.40.1.

Other improvements include battery preconditioning, driver door unlock and radio station logos, while existing features have launched in new regions.

New Features

Let's start with the Sentry and Dog Mode combo. Both of these features would rate high on items that Tesla owners appreciate about their vehicles. Sentry is a best-in-class security/surveillance system, and Dog Mode keeps the cabin at an appropriate temperature for your pet while you are away.

However, the two systems did not work together because Sentry would constantly be triggered whenever the dog moved inside the vehicle. For those who have dogs that love car rides, this meant not being able to use Sentry to protect your car and your dog. Now both features can be used together for most vehicles. This update silences Sentry Mode alarms while still recording and keeping the temperature safe for your pooch.

Listening to the radio may get more appealing with the addition of radio station logos to the media player.

The radio in a Tesla doesn't get a lot of recognition since competes against music streaming services and other entertainment that have much more engaging screens, but Tesla did a great job with its radio implementation.

The radio will automatically scan for local stations, so you can just tap to get to your favorite station. It also offers a direct input instead of a radio dial and now features radio station icons to make it easier to find your favorite station. With this update the list of radio stations has been changed to a grid to make room for the station name and logo. When playing an FM radio station, the station's logo will also appear in the album artwork area of the music player. (Photo credit to ArsalamiSandwich).

Voice directions are now available in Hebrew in the Middle East. Tesla continues to expand the languages offered in its vehicles. It's estimated that 9 million people speak Hebrew worldwide.

Improvements to Existing Features

In an effort to speed up charging times, the thermal system control will now be optimized to match the charging station's power capability. The company has been expanding its vast network of Superchargers, which means there are many variations in the station output. This update means your Tesla won't waste too much energy preparing the battery if you're headed to a slower DC charging station.

Update 2021.44 added the ability to only unlock the driver's door when the handle is pressed to improve safety. However, it wasn't ideal when traveling with passengers as they would have to wait until you get into the vehicle to open the other doors.

With update 2022.40, Tesla did what it does best — improve vehicle features. If you have the Driver Door Unlock Mode feature on, you can now hold and press the interior driver door switch to unlock all vehicle doors and trunk.

If this update Tesla is also adding this feature to the new Model S.

To access Driver Door Unlock Mode, tap Controls > Lock > Driver Door Unlock Mode.

Expanding to More Regions

More vehicles and regions now have access to a consistent regenerative braking feel even when it's limited. For example, regenerative braking may not be available when the battery is at a max charge or in certain weather conditions. In May 2022, Tesla sent out an update to many areas and vehicles, allowing the car to behave the same way when it is decelerating with or without regenerative braking. This feature enables drivers to perfect the one-foot driving technique at all times.

With this update, it is now available for some legacy Model S and Model X vehicles.

With winter coming, the Tire Configuration program is now for the Model Y as well. It allows users to reset the learned tire settings after a tire rotation or replacement for an improved driving experience. To reset, tap Controls > Service > Wheel & Tire Configuration > Tires.

Other changes include exterior lighting improvements and Sentry Mode Live Camera Access added to Israel, Supercharger details included in China, and Boombox is now available in Japan. However, Hong Kong went against the trend as it continues to allow fewer features. The dashcam viewer has been removed, the country recently took away Tesla's arcade and Toybox.

Tesla update 2022.40.1 has just begun rolling out and it's available on less than 1% of Tesla's vehicles (why Tesla doesn't update all vehicles at once).

Tesla Smoking While Supercharging? A Look at What's Actually Happening

Hot_Engineering3140 on Reddit

Winter is here, and temperatures are dropping, so one of the most common Tesla questions is about to resurface.

If you’ve landed here after frantically searching about “smoke” coming from your Tesla while Supercharging, take a deep breath—it’s completely normal.

Tesla Smoking While Charging

If you’re Supercharging in freezing weather—even with preconditioning—you might notice steam rising from your Tesla. But rest assured, your car isn’t smoking.

Your Tesla’s heat pump is hard at work warming both the cabin and battery to keep you comfortable and ensure optimal charging temperatures. Over time, condensation and ice build-up in the heat exchanger coils.

Why Does It Happen?

When you reach a Supercharger with your vehicle, the heat pump is still running hot, but without the cold air from driving to keep the heat exchanger coils cool, the ice and condensation quickly start to evaporate—creating what looks like smoke.

Since this typically happens near the front of the vehicle, where a car would traditionally have an engine, new vehicle owners can be startled by the discovery. However, rest assured that it’s just water vapor and it’s completely normal in cold weather.

In fact, this behavior can be experienced in any EV with a heat pump in cold climates. So, if you saw steam coming out of your vehicle and panicked, don’t worry—you’re not alone.

Now that you know what’s happening, go ahead and Supercharge with confidence.

Tesla Improves YouTube App With Smoother Playback

Not a Tesla App

Tesla made a lot of improvements in the 2024 Holiday Update, including more than 15 undocumented improvements that were included in the release. One of these was a stealthy performance improvement to the YouTube app.

Several people have mentioned they’ve seen improved performance on YouTube since this year’s Holiday Update - and there’s an interesting reason why.

YouTube Improvements

The improved YouTube performance in Tesla vehicles comes from an unexpected source—Tesla actually rolled back support for YouTube’s newer AV1 video encoding. Instead, vehicles now default to the older VP9 encoding standard.

While AV1 is highly efficient in terms of bandwidth, it requires considerably more processing power to decode and display videos. VP9, on the other hand, is less computationally demanding but uses more bandwidth to achieve the same video quality. This trade-off means smoother playback and better overall performance, even if it comes at the cost of slightly higher data usage.

Intel Inside

The VP9 video codec that the YouTube app is now using is much easier to decode, making it less taxing on the vehicle’s processor. This change is particularly beneficial for Tesla vehicles with Intel processors, which previously struggled to stream video at just 720p. When using AV1, these vehicles often experienced stuttering, sometimes forcing the YouTube app to automatically downgrade playback to 480p.

With this update, Intel-based Teslas should now be able to stream at 1080p smoothly. Streaming at 1440p is also possible, although occasional stutters still occur as the system keeps up with the decoding process.

Intel-based vehicles are the big winners with this change, but this appears to affect AMD Ryzen-based infotainment units as well, providing even smoother playback.

Chromium Web App

Tesla’s Theater apps aren’t native applications; instead, they run as chromeless web apps, leveraging the open-source browser built into Teslas known as Chromium (the open-source version of Chrome). Although this works quite well, there is a severe limitation - Chromium hardware acceleration isn’t supported on Linux, the operating system Tesla uses for their OS.

As a result, Tesla vehicles rely on software decoding instead of hardware decoding, which would otherwise handle video playback far more efficiently. A potential solution could be for Tesla to transition away from Chromium-based web apps in favor of a Mozilla Firefox-based browser, as Firefox does support hardware acceleration on Linux. This switch could also open the door to better streaming performance and the possibility of expanding Tesla’s in-car entertainment options.

However, Tesla’s choice of Chromium likely stems from Digital Rights Management (DRM) requirements for streaming services like Disney+ and Netflix, which rely on DRM-enabled playback. Firefox on Linux has had inconsistent support for DRM due to codec availability and variations in operating system versions.

We’re hopeful that Tesla will either adopt Firefox or develop a fully native application to improve video streaming, rather than continuing with the current web-based Tesla Theater. This shift could also pave the way for additional in-car applications built on Tesla’s native Linux environment—perhaps even reviving the long-rumored Tesla App Store.

Regardless, this update is a welcome improvement, particularly for YouTube, which remains one of the most widely used Theater Mode apps due to its accessibility, free content, and mix of short and long-form videos. It remains to be seen whether similar improvements are made for Netflix, Disney+, or other streaming platforms.

If you’ve noticed improved performance in Theater Mode, now you know why.
