Tesla will allow you to further customize its Cabin Overheat Protection feature
Cabin Overheat Protection (COP) is an amazing feature that is available on all Teslas.
If the interior of the vehicle gets too hot, the car can automatically turn on the HVAC fan, allowing cool air to be brought in to help cool the cabin.
You can also choose to have the vehicle use the AC to more effectively cool down the interior of the car, although it comes at the expense of some battery drain.
Up until now the temperature at which Cabin Overheat Protection turns on has not been configurable and is set at 105° F.
However, last night Elon Musk announced that Tesla will be bringing some improvements to Cabin Overheat Protection. You’ll soon be able to adjust the temperature at which COP turns on.
Although Elon says that you'll be able to adjust the temperature at which COP kicks on, it may be limited to a certain range. Maybe somewhere along the lines of 90° to 120°.
After all, if you want to keep the car any cooler, you could always use Climate Keeper.
It'll be interesting to see if Tesla includes any additional improvements to Cabin Overheat Protection, such as only allowing it to cool at certain times or locations. It could also allow the vehicle to automatically vent the windows to help further cool the interior.
Elon recently said that Tesla would incorporate a feature that would allow the vehicle to automatically close its windows when it starts raining. It's certainly possible that these features could be tied together in a 'Summer Improvements' package.
Elon said that the enhancement will be included in the next software update. Elon is likely referring to the next major update and not any minor revisions to 2022.20.
The next major release is expected to be 2022.24, which is probably still 2-4 weeks away.
Tesla’s automatic cabin overheat protection should make a real difference with record heatwaves.
Ability to adjust activation temperature coming with next software release.
Cabin Overheat Protection currently has three options: Off, No A/C, and On. When the feature is set to off, which is the default, the vehicle will simply not do anything when the interior temperature reaches 105°.
When “No A/C” is selected, COP will simply utilize the fans to cool the cabin. This will help cool down the cabin slightly, but during hot days the interior of the cabin will still climb into 130° and beyond.
The best way to keep the cabin cool during hot days is to set Cabin Overheat Protection to "On," which will let the vehicle utilize the AC.
While this method is best for keeping the interior of the vehicle from exceeding 105° F, it still may not be enough in excessive heat. There is no gaurantee that the cabin will below 105°.
To enable Cabin Overheat Protection in your vehicle, head to Controls > Safety and scroll down until you see Cabin Overheat Protection and pick your preferred option.
You can also turn it on from your Tesla app by navigating to the Climate section and sliding up the bottom drawer for additional climate options, such as Dog Mode, Camp Mode.
In the app you can also choose to receive a push notification on your phone when COP is activated by going to Profile > Settings > Notifications.
COP is a nifty feature if you live in a warmer climate and dislike getting into a car that is excessively hot. It can also be life-saving if a small child or pet is ever forgotten in the car.
Cabin Overheat Protection will remain on up to a maximum of 12 hours after the car is parked, or until the battery reaches 20% of charge.
Look for this improvement and others in Tesla's upcoming update.

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.
