The inside of a car can get extremely hot in summer months. It doesn’t take much before the temperature inside of a vehicle becomes dangerous. For you, your loved ones or your little furry friends.
Tesla's Dog Mode screen
Not a Tesla App
Sometimes you may find yourself in a situation where you have a pet with you, but you need to run to a store. Even with your windows cracked, it’s a bad idea to leave your pet in the car on warmer or cold days.
Introducing Dog Mode
Tesla solves this problem with Dog Mode. Since Teslas are electric, there’s no engine that needs to run, meaning you can run any system in the car without needing the car to remain on. This includes the heater and air conditioner.
Dog Mode allows you to set the temperature in the car, just like you’d set it at home, and the car will keep the interior of the vehicle at that temperature until you return. It doesn’t matter whether the cabin needs to be heated or cooled, the car will control the HVAC to keep the vehicle at the selected temperature.
Letting Others Know Your Pet is Safe
Since leaving your pet alone in a vehicle isn’t normally a good idea and people may not be familiar with Tesla’s Dog Mode, Tesla also displays a message on the screen.
Tesla does a great job at letting bystanders know that your pet is safe inside of the car. Once Dog Mode is activated, a message will display on the car’s large center screen letting people know your pet is safe.
The screen will show a cute picture of a dog and display a message that states, “My driver will be back soon.” It will furthermore let them know to not worry, and that the heater or AC is on and it will display the current temperature inside of the car.
What Happens If the Battery Gets Low
The car will only let you activate Dog Mode if your charge level is above 20%. This is to be sure that there’s enough of a charge to keep your pet cool or warm and a buffer for you to get home.
If you have enabled Dog Mode and the battery reaches 20%, Tesla will send you a notification on your phone letting you know that the battery is getting low and that you should return to your car.
Dog Mode will remain on as long as possible until the car runs out of battery.
How Long Can You Leave Dog Mode On
The heater or air conditioner is getting power directly from your car’s battery. Besides driving, climate control is one of the largest draws of power. The amount of power actually consumed, or the amount of time your car can remain in Dog Mode is entirely dependent on the outdoor temperature and how much energy the car needs to use to keep the cabin at the selected temperature.
A rough estimate is that your car will use about 4 miles of range per hour in which the climate system is on. This will differ based on whether you’re using the heater or AC, your Tesla model and the outside temperature.
Which Models have Dog Mode
Dog Mode is a standard feature available in Tesla Model Y, Model 3, Model S and Model X. You do not need to have Tesla’s Premium Connectivity in order to receive notifications from your Tesla or to control your Tesla from the Tesla app.
How to Turn On Dog Mode
To activate Dog Mode you’ll need to be inside of the vehicle. Tap on the fan icon along the bottom navigation bar and you should see the HVAC screen come up. Toward the top right corner, you’ll see different modes, such as On, Dog and Camp.
Touching Dog Mode will activate it as soon as you leave the car. Just set your temperature and you’re all set.
How to Turn Off Dog Mode
Once you get back in the car and start driving, Dog Mode will automatically turn off. If you come back for just a minute and leave again, Dog Mode will remain on.
Dog Mode is a fantastic feature and shows a clear benefit of electric cars, where you don’t need to have the engine on in order to power the HVAC system. Please use it with caution and don’t leave your dog or pet unattended for long periods of time.
FSD’s insatiable appetite for AI compute is taking shape once again at Giga Texas, where Tesla is building out Cortex 2.0 — its second large-scale GPU supercomputer cluster — on the facility’s north side.
This confirmation comes thanks to the detailed research and findings by Giga Texas drone pilot Joe Tegtmeyer, who shared his findings on X.
For months, there has been some speculation on what this new site would be - new storage, the Optimus production line, preparation for the Cybercab’s unboxed assembly process, and more. Now, thanks to permits filed by Tesla, we know that this new area is destined to become the second supercomputer destined for FSD training.
Cortex 2.0
There are some key details we can unpack from what we’ve learned about Cortex 2.0. The new facility will be on the north side of Giga Texas, opposite Cortex 1.0, which is on the south side. The permits explicitly tie the usage of this expansion to Cortex 2.0, namely through the fact that it is a data center.
This is actually a change from Tesla’s original plans - the northern section was intended to be used as a central campus support facility, with three smaller facilities and water storage tanks. Now, it has been redesignated as Cortex 2.0 and is one large structure.
The permits that have been filed have already been approved and cover the foundations, underground water mains, and building itself. The steel structure is actively being put together on the concrete foundations, and about 50% of the roof decking is already complete, bringing the exterior shell closer to completion.
Fueling FSD’s Brain
The deployment of Cortex 2.0 is the latest in Tesla’s massive and ongoing investment in the computational power required to train FSD. While this primarily covers FSD for cars, this will also eventually apply to Optimus, which is powered by the same AI4 computer and also runs a variant of FSD.
This isn’t Tesla’s first foray into large-scale AI infrastructure and won’t be their last. Alongside Dojo, their home-grown AI supercomputer, Tesla has been partnering closely with Nvidia to ensure they have the GPUs necessary to do all the hard work. Cortex 2.0 is the next iteration, and once it's fully online, we can expect that Tesla’s work on FSD will accelerate even further.
Especially since Elon is planning something truly outrageous once again:
Been thinking about the fastest way to bring a terawatt of compute online.
That is roughly equivalent to all electrical power produced in America today.
With European Tesla owners eagerly awaiting any news on FSD in Europe, we’ve seen Tesla tease FSD, and also point out exactly what the barrier has been - regulatory approval. Now, following the latest meeting of UNECE, new regulatory amendments are set to unlock “System-Initiated Maneuvers” (SIM) on highways across participating European nations.
This development, highlighted by Kees Roelandschap on X, notes that the latest documents from the United Nations Economic Commission for Europe (UNECE) center on amendments to UNECE regulation 171. These changes were formally adopted into UNECE during the WP29 World Forum in March 2025.
Now, the amendment that will enable SIM will come into force on September 26, 2025. This six-month period after approval is standard UNECE procedure and allows objections from party states that would halt the implementation. Objections to UNECE amendments are genuinely rare, with 95% of amendments passing without objection once the World Forum adopts them.
What This Means for FSD in Europe
System-initiated maneuvers will allow your Tesla to perform actions autonomously, such as changing lanes on a highway, while the driver remains fully responsible for supervision. This is a substantial step up from current regulatory standards that only allow for suggested maneuvers or require explicit driver initiation for every automated maneuver.
This inches towards the more normal “hands-off, eyes-on” approach that Tesla has taken with FSD Supervised in North America and China. This regulatory change will help to provide the legal frameworks needed to deploy more advanced autonomy capabilities in Europe, at least matching what’s available on highways in North America.
The UNECE regulation will apply to all countries that adopt its standards, including the European Union, Japan, and South Korea - unless they specifically block it. This is a relatively positive development, but there are some hiccups.
This regulation only allows for system-initiated maneuvers on highways, not low-speed roadways. That means the city streets portion of FSD’s capabilities - including handling ‘Start FSD from Park` and reaching your destination’s parking spot - still won’t be available in Europe.
In addition, the UNECE framework has stricter requirements for driver monitoring and attentiveness - which means that some nags, including the dreaded wheel nag, are likely to remain a key portion of the experience.
Progress on autonomous driving regulations in Europe has been fraught with indecision and caution, which has been a source of frustration for many who are watching the everyday progress of FSD in North America, and more recently, in China. Even with individual countries recently approving testing of FSD on public roads, harmonized UNECE regulations are the key to wider, consistent deployment, which will allow everyday customers to use it as well.
While the path to full parity with North America may be long and involve even more regulatory machinations, the upcoming implementation of System-Initiated Maneuvers is a big step forward for Tesla owners in Europe. It is a key piece of the puzzle that will help Tesla bring some more features of FSD to Europe, assuming the September timeline holds.
