While Tesla’s exciting holiday update is now behind us, it left us with amazing new features, such as weather radar, Apple Watch support, mobile Dashcam viewer, SiriusXM, and so many other great features that some of us now use every day.
However, it doesn’t end there. Tesla always includes other smaller changes that don’t make it into the release notes, and the holiday update was a big one in terms of undocumented changes.
We’ll go through all the new features that are now available in your vehicle that Tesla didn’t show in their release notes.
Precipitation Map
Not a Tesla App
While this feature did make it to the release notes, some users may still not be aware that the Precipitation Map (weather radar) is now available on all Teslas with the Intel infotainment unit (except for legacy Model S/X). This feature was requested so long ago that, honestly, we didn’t think it’d ever be released. All Model 3, Model Y and 2021+ Model S and X vehicles now have access to the weather radar map overlay.
Fart on Sit
Not a Tesla App
For the Emissions Testing Mode easter egg, you can now have your vehicle fart when someone sits down in their seat.
The sound will come from the direction of their seat. For example, a fart sound will sound from the front-right speaker when someone sits in the front passenger seat. It will play the sound selected in the fart selection box, or play a random fart if you choose "I'm so random."
This option defaults to off after every drive.
Voice Assistant
Not a Tesla App
You can now say 'Hi' or 'Hello' to your vehicle through the voice command prompt, and the vehicle will respond with "Hello!"
If you use Tesla's voice commands, there are a few changes. When you press the voice command button on the steering wheel, you may now not get audible feedback that the button has been pressed. This will depend on whether there’s music playing or other circumstances.
When sending a text message through a voice command, you may now have to press the steering wheel button again to start dictation after choosing a recipient. It’s not clear what’s causing this change, as sometimes it goes straight into dictation mode, while other times it ask you to press the button to start dictation.
Equalizer
Not a Tesla App
You can now reset the equalizer settings with the touch of a button by tapping the new circular arrow to the right of the equalizer. This will bring all settings back down to 0.
Performance Improvements
Not a Tesla App
Intel users are seeing performance improvements while using the Tesla interface, especially in more demanding areas like Tesla Theater. Videos on YouTube now stutter less and Tesla Theater can be minimized more smoothly than before.
The media controls can now control YouTube videos and other web video content as well, even after the vehicle is put into drive.
Service Mode Updates
Not a Tesla App
Several screens in Service Mode have been updated to show larger visualizations, such as the Airbags and Seats menu.
Tesla has also introduced several new visualizations to vehicles with the Intel infotainment unit, that were previously only available on AMD-based vehicles. Some of these includes Coolant and HVAC options.
The only new feature in Service Mode is for the Cybertruck under Service Mode Plus, which includes:
Connector Reference (Service Mode Plus): A new Connector Reference panel is available to help find connectors and highlight harnesses on the vehicle. Rotate the 3D model to explore or type in the search bar to find a specific connector.
Rearranged Menus
Not a Tesla App
With the addition of the Seats menu to settings, Tesla has now rearranged the menu options so that the more used options are now more easily accessible.
The Software menu has been moved up, while other options like Navigation and Trips have been moved down to be close to WiFi, Bluetooth and Upgrades.
Selected Custom Lock Sound
Not a Tesla App
The currently selected custom lock sound is now shown underneath the Lock Confirmation Sound option in the Controls > Locks menu.
Ambient Lighting Easter Eggs
Not a Tesla App
The Rainbow Road and Santa Mode easter eggs have been updated on vehicles that include the ambient lighting feature.
There are new options in these easter eggs that let you enable or disable the ambient lighting while the easter egg is active.
If enabled, the light strips will cycle through colors of the rainbow when the Rainbow Road easter egg is enabled. For Santa Mode, the interior lights will cycle between red, green and white.
Updated Energy App
Not a Tesla App
The Consumption tab in the Energy app has been updated with several changes, including:
The last 200 miles are now shown, instead of a user-selectable, 5, 15 or 30 miles.
Instant Range / Average Range has been removed to simplify the interface.
The average range as moved to the top left and now shows the offset from the vehicle's EPA-rated Wh/mi
Total energy consumption is now displayed at the bottom left.
The colors now have different meanings. Before this update, yellow meant the vehicle was using energy, while green meant the vehicle was generating energy through Regenerative Braking. However, now, yellow means that the vehicle consumed more than the EPA average, and green means that the vehicle consumed less than the EPA average and doesn’t necessarily mean it generated energy.
Toll Roads
Not a Tesla App
When navigating to a destination, the alternative routes menu that is displayed when you first enter a destination will now show you which routes include tolls by displaying a dollar sign icon next to the travel time.
Limiting Explicit Content
Not a Tesla App
The Exlicit Content toggle under Audio Settings now applies to YouTube Music as well. This now supports LiveOne, Apple Music, Apple Podcasts, and TIDAL.
Charging Icons
Not a Tesla App
Tesla has redesigned the charging pins that appear on the map. Supercharger and third-party charger pins are now oval-shaped instead of circular.
Instead of just having the number of charging stalls available, Tesla has added the charging icon to make it more obvious these are charging stations.
Adjust Dashcam Viewer Speed
Not a Tesla App
You can now adjust the Dashcam Viewer's playback speed. Users can pick from 0.5x, 1x or 2x playback speeds by tapping the playback speed button.
Tire Pressure Indicator
Not a Tesla App
Tapping the tire pressure indicator will now open the tire pressure card on the left side of the screen instead of opening the Service menu under Controls > Service.
If you ever spot a change that isn’t listed in Tesla’s release notes, we’d love to hear about it!

Tesla offers owners an easy-to-use battery health tool, which allows users to view the degradation of their vehicle’s battery and improve the range estimate.
Battery Health
Like all batteries, electric vehicle batteries naturally degrade over time as a result of the chemical reactions that occur during charging and discharging cycles. Other factors also play a role, but the number of charge cycles and how long the battery stays at low or high states of charge play one of the biggest roles.
Your battery’s health refers to how much of its original energy capacity remains. For example, a battery at 85% health has lost about 15% of its capacity, meaning your vehicle will deliver roughly 85% of the range it had when new.
Battery Degradation
Battery degradation is worst in the first few months of ownership, and you will see the steepest degradation (1-3%) as your vehicle settles in. Part of this initial decline is due to the Battery Management System (BMS), which recalibrates to provide a more conservative and accurate estimate of your vehicle’s range and charging capacity.
According to Tesla, vehicle batteries generally degrade at a rate of about 15% per 200,000 miles, with the first year of ownership accounting for approximately 5% of this degradation. Battery degradation is less of an issue in modern EVs than many people think, because the BMS systems have become much more accurate and intelligent.
Tesla offers a long warranty on its vehicles, covering both the battery and the drive units. These warranties cover up to 70% pack retention, meaning that if your battery health degrades below the 70% mark while under warranty, Tesla will replace your battery pack.
Tesla provides a drive train and battery warranty on its vehicles, which is longer than the standard vehicle warranty. This warranty guarantees the battery will have at least 70% of its original capacity within the given time period. If your battery health drops below that threshold during the coverage period, Tesla will replace the battery pack.
The warranty varies slightly based on your Tesla model and configuration, which is outlined below:
Vehicle
Warranty
Model S, Model X, Cybertruck
8 Years / 150,000 mi (240,000km)
Model 3 / Model Y RWD
8 Years / 100,000 mi (160,000km)
All Other Model 3 / Model Y
8 Years / 120,000 mi (192,000km)
How to Test Battery Health
Not a Tesla App
While you can usually get a fairly accurate estimate of your Tesla’s battery health by calculating the amount of miles the vehicle could travel when charged to 100% and comparing that to the vehicle’s original range, Tesla has also added a tool to give you a better estimate.
Tesla has a user-friendly method of testing your vehicle’s battery health. The tool is practically identical to the one available through Service Mode, and the test and results are the same.
In order to test your vehicle’s battery health, you can navigate to Controls > Service, and then scroll down and select Battery Health. Upon tapping the button, the vehicle will display requirements for the battery test and the date and health of your last battery test.
Battery Health Test Requirements / How Long It Takes
Your vehicle will need to plugged in to a Wall Connector or Mobile Connector for up to 18 hours to run the battery test. The charger will need to be able to provide at least 5 kW of power, which is roughly about 20 amps at 240v.
The total amount of time the test will take will vary based on your vehicle’s battery size, your charging speed and the current battery level. If you’re unable to finish a battery health test and need the vehicle before it has completed, you can stop the test at any time.
Your vehicle will also need to be at a 20% or less state of charge, so you’ll need to plan accordingly.
The other requirements should be straight forwar and are listed here:
Vehicle is in Park
Battery level is at 20% or less
Vehicle is connected to the Internet
No software updates are scheduled
No battery or thermal alerts are active
Vehicle is connected to an AC charging station
AC charging equipment can provide at least 5 kW of power
Running the Battery Test
During the battery test, your vehicle will discharge and charge your battery to calibrate the BMS. Therefore, the lower the state of charge, the quicker the test will run and less energy will be wasted.
Your vehicle will run the motors and heat pump or heater to help discharge energy until the batteries are nearly empty, and then begin charging.
During the test, you may hear your vehicle’s fan run at maximum speed and become very loud, especially in an enclosed garage while the vehicle is discharging. This is normal and your vehicle is just using up energy.
Battery Test Results
Not a Tesla App
Once the battery test has completed, you’ll receive a notification in the Tesla app. You can check the results in the vehicle or in the Tesla app by navigiating to Service > Battery Health.
Most vehicles will have a degradation range between 10-20%, depending on your charging habits, age and use of your battery.
If you receive a result that’s 70% or less and are within the warranty period, you should reach out to Tesla for a replacement.
Since your battery test will recalibrate the vehicle’s BMS, you may see your vehicle’s range adjusted after the test. Keep in mind that the range of your vehicle hasn’t been affected and the vehicle is simply displaying a more accurate estimate of its range.
Note: Once the battery test completes, the vehicle will keep your battery at 100%, which isn’t a good practice for battery health. It’d be a good improvement if Tesla used up energy to bring the battery level back to the charge limit if the vehicle isn’t used after an hour or two.
You should not leave your vehicle at 100% unless you have a LFP battery. Plan to go for a drive shortly after the battery test completes. If you can’t drive, we recommend running the climate system to use up some energy.
Test Limitations
Since Tesla’s battery test uses up energy and discharges your battery to near 0% and then charges it to 100%, it’s best not to perform it often. Tesla also only allows one battery test every six months, unless you go into Service Mode to perform the battery test.
Tesla offers users some specific tools under its service menu (Controls > Service). These tools include features such as Car Wash Mode and Tow Mode. Just like other vehicle features, these are also updated and improved over time.
As Tesla vehicles use electric motors, towing them with any wheels on the ground could cause the motors to backfeed energy, generating considerable amounts of heat. If done for an extended period of time, especially at higher speeds, it could cause damage since the vehicle isn’t running its coolant loop to dump waste heat.
To help solve this problem, Tesla provides Tow Mode, which breaks down the steps needed to tow a Tesla. It also provides an easy way to put the vehicle in neutral and disengage the parking brake.
The improvement to Tow Mode now displays a checklist similar to Car Wash Mode. Each item in the list will light up green or red, depending on whether it’s already in the correct setting for Tow Mode.
Tesla has also added a readout of the low-voltage battery. While this could be useful for anyone wanting to check the current on their LV battery, it’s an important detail to be aware of if you’re towing because the vehicle’s high-voltage battery has been run down. All of the vehicle’s electronics are powered by the LV battery, and depleting it could cause the display to not turn on, as well as prevent access to certain vehicle features.
The vehicle shown in the diagram is also unique to the vehicle you are driving - a Model 3 will display a Model 3, while the Cybertruck will display a Cybertruck - just a subtle touch of Tesla precision to the entire presentation.
You can activate or check out Tow Mode from Controls > Service > Tow Mode.
Tire Service Improvements
Tesla has also improved its Tire Service menu, which is now tied into Maintenance History. These menus allow you to switch the wheels and tires your vehicle is using. It’s important to note that the wheel is not only used in the vehicle’s visualization, but also has impacts on the vehicle’s ability to accurately predict its range.
In the Tire menu, Tesla has added a Service Type dropdown, allowing you to select why you’re switching your tires. You can choose whether you’re rotating your tires, replacing them, or swapping them out for seasonal tires. This change will then be recorded in Maintenance History, allowing you to track the maintenance of your tires, including the date of the last maintenance and the ability to see the mileage on your current set of tires.
You can navigate to the Wheel and Tire menu by going to Controls > Service > Wheel & Tire.
The updated Wheel and Tire menu
Not a Tesla App
Cybertruck
As a note, the Tire Service improvements are not fully implemented in the Cybertruck in the primary menu. If you wish to mark a Seasonal Tire Change in your Cybertruck, you’ll need to head into Service Mode and add a Correction Code for Seasonal Tire Change from there.
We expect Tesla to fix or add this in an upcoming update for the Cybertruck.
