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.
Tesla’s been on a roll with Supercharger improvements lately, from the 325kW charging update for the Cybertruck, to 500kW with V4 Superchargers coming next year. While those improvements have been limited to the Cybertruck, Tesla didn’t put all their focus on their new flagship vehicle, but looked at their more affordable vehicles as well.
LFP Battery Heating
Tesla’s Superchargers can now heat LFP Batteries - those that are in the Model 3 and Model Y Rear Wheel Drive variants. This applies to Long Range and Standard Range models, which saw a limited run. This is another update included as part of the 2024 Tesla Holiday Update - which really arrived with a lot of unannounced new features and capabilities.
The change is pretty interesting - Superchargers of the V3 and V4 variety can now pre-heat batteries for Model 3 and Model Y vehicles equipped with LFP battery packs. That means those vehicles are able to get back on the road faster when it's extremely cold. Of course, Tesla still advises you to precondition before you arrive, saving drivers time and money.
Max de Zegher, Tesla’s Director of Charging, also commented on the new feature. Essentially, Tesla is inducing an AC (alternating) ripple current through the battery to warm it up. Keep in mind that Superchargers are DC charging. That means it is possible to get a cold-soaked LFP vehicle on the road 4x faster than before, assuming that it didn’t precondition at all and that it is in the worst-case scenario (below 0ºF).
In essence, Tesla is using some engineering magic to turn the circuits inside the LFP battery into an electric heater - and powering that heater through the Supercharger. An AC ripple current is a small oscillation in the DC charging current that generates heat through electrical resistance, warming up the battery. Those ripples are a byproduct of converting AC to DC and back - so Tesla is using the onboard charger to induce those ripples to warm up the battery. Definitely an innovative technique that’s really only possible with the versatility of the NACS connector.
We’re hoping Tesla can implement this across their full lineup of vehicles, but we’ll have to wait and see how it is trialed across LFP vehicles first and if it is even possible on vehicles with 2170 or 4680 battery packs.
Tesla launched two FSD updates simultaneously on Saturday night, and what’s most interesting is that they arrived on the same software version. We’ll dig into that a little later, but for now, there’s good news for everyone. For Hardware 3 owners, FSD V12.6.1 is launching to all vehicles, including the Model 3 and Model Y. For AI4 owners, FSD V13.2.4 is launching, starting with the Cybertruck.
FSD V13.2.4
A new V13 build is now rolling out to the Cybertruck and is expected to arrive for the rest of the AI4 fleet soon. However, this build seems to be focused on bug fixes. There are no changes to the release notes for the Cybertruck with this release, and it’s unlikely to feature any changes when it arrives on other vehicles.
FSD V12.6.1 builds upon V12.6, which is the latest FSD version for HW3 vehicles. While FSD V12.6 was only released for the redesigned Model S and Model X with HW3, FSD V12.6.1 is adding support for the Model 3 and Model Y.
While this is only a bug-fix release for users coming from FSD V12.6, it includes massive improvements for anyone coming from an older FSD version. Two of the biggest changes are the new end-to-end highway stack that now utilizes FSD V12 for highway driving and a redesigned controller that allows FSD to drive “V13” smooth.
It also adds speed profiles, earlier lane changes, and more. You can read our in-depth look at all the changes in FSD V12.6.
Same Update, Multiple FSD Builds
What’s interesting about this software version is that it “includes" two FSD updates, V12.6.1 for HW3 and V13.2.4 for HW4 vehicles. While this is interesting, it’s less special when you understand what’s happening under the hood.
The vehicle’s firmware and Autopilot firmware are actually completely separate. While a vehicle downloading a firmware update may look like a singular process, it’s actually performing several functions during this period. First, it downloads the vehicle’s firmware. Upon unpacking the update, it’s instructed which Autopilot/FSD firmware should be downloaded.
While the FSD firmware is separate, the vehicle can’t download any FSD update. The FSD version is hard-coded in the vehicle’s firmware that was just downloaded. This helps Tesla keep the infotainment and Autopilot firmware tightly coupled, leading to fewer issues.
What we’re seeing here is that HW3 vehicles are being told to download one FSD version, while HW4 vehicles are being told to download a different version.
While this is the first time Tesla has had two FSD versions tied to the same vehicle software version, the process hasn’t actually changed, and what we’re seeing won’t lead to faster FSD updates or the ability to download FSD separately. What we’re seeing is the direct result of the divergence of HW3 and HW4.
While HW3/4 remained basically on the same FSD version until recently, it is now necessary to deploy different versions for the two platforms. We expect this to be the norm going forward, where HW3 will be on a much different version of FSD than HW4. While each update may not include two different FSD versions going forward, we may see it occasionally, depending on which features Autopilot is dependent on.
Thanks to Greentheonly for helping us understand what happened with this release and for the insight into Tesla’s processes.
