Improved Driving Visualization (New)
New Feature
for Model S, 3, X and Y (Undocumented)
The on-screen driving visualization has improved and includes more detail.
This visual representation of the vehicle and surroundings is for reference and orientation only and isn’t intended to represent all objects, road markings, or other variables. Drivers should continue to remain alert at all times.
Autopark
New Feature
for Model S, 3, X and Y (Undocumented)
Your vehicle can now automatically park — and parallel park — in designated spaces.
When you’re driving at low speed, your display highlights potential parking spaces. Autopark shows a circular P symbol to suggest a space, but you can choose any highlighted space.
To start parking, stop the vehicle, press Start, and release the steering wheel so it can move freely. Refer to the Owner’s Manual for more detail.
As with all Autopilot features, you must continue to pay attention and be ready to take immediate action including canceling Autopark.

May be visible in cold weather, continue charging.
Time Until Charging Starts
New Feature
for Model 3 and Y
When you arrive and plug in, if your vehicle battery has not warmed up enough, you’ll now see how long it will be until DC fast charging starts.
Estimated Battery Range Update
New Feature
for Model S, 3, X and Y
Your estimated battery range now incorporates additional characteristics related to battery aging over time.
Supercharging in Cold Weather
New Feature
for Model 3 and Y
If you’re heading to a charger in colder conditions, use the vehicle Navigation to route there. In addition to preparing the battery, this now automatically starts warming the charge port inlet.
Other Tips for Charging in Cold Weather
When You Plug In — Clear away ice and other debris from your charging cable connector and charge port, and check that they’re fully connected.
When You Unplug — After charging in frozen conditions, if you can’t unplug, try warming the charge port inlet:
In the Tesla app, you can turn on Defrost Car, or in the vehicle, turn on the Rear Defrost. Alternatively you can prepare ahead of time: In the Tesla app, go to Schedule > Departure, or in your vehicle settings, go to Charging > Schedule > Settings > Preconditioning.
If warming alone is unsuccessful, you can pull the manual release (in the trunk) to disengage the charge port latch.
See your Owner’s Manual sections on Cold Weather Best Practices and Charging.
Ultra-Wideband Phone Key
New Feature
for Model 3 New, X New and Cybertruck
Ultrawide band (UWB) technology is now available for Phone Key. So your vehicle and Phone Key can communicate with greater accuracy to more responsively lock, unlock, and open Automatic Doors.
In the Tesla app, choose Phone Key > Upgrade and follow the instructions. After setup, keep your iPhone Settings for Nearby Interactions on for Tesla. Requires iPhone 11+ and Tesla app 4.29.5+.
Reminder to Plug In at Home
New Feature
for Model S, 3, X and Y
You’ll now receive a reminder on your phone to plug in your vehicle when you park at home with less than half of your Charge Limit.
To receive this notification, you must have your Home location set and have charged there previously. Your vehicle’s location is not shared with Tesla (see tesla.com/privacy).
Improved Ride and Handling
New Feature
for Model Cybertruck
Get a more consistent response on different road surfaces and greater comfort on rough winding pavement in Sport Mode or when Custom Ride & Handling is set to Focused. Also expect reduced pitch and body roll in Off-Road Mode.
In your vehicle settings, go to Dynamics to choose your Drive Mode.
Over-the-Air Recall: Telltale Text Size
New Feature
for Model S, 3, X and Y (not available in Germany)
As the remedy for US Recall 24V-051, this update to your vehicle software increases the text size of three telltales.
After installing this vehicle software update, you don’t need to take any further action for this recall.
More Efficient Charging
New Feature
for Model 3 and Y (available in Germany)
Your vehicle now adjusts to the power level of each DC charging station. So battery preconditioning when you’re navigating to a charger, and then charging, can be more efficient.
Adaptive Headlights
New Feature
for Model 3 New (available in Germany)
The high beams now adjust to reduce glare for other drivers and cyclists.
By detecting other road users and selectively dimming individual pixels of the headlights, the high beams can remain on longer, enabling better visibility at night.
To turn it on, go to Lighting > Adaptive High Beam in your vehicle settings.
Security Improvements
New Feature
for Model S, 3, X and Y
This update includes important security fixes and improvements.
