Tesla released software update 2025.38.3.1 on October 14 2025 for Model 3 Model Y and Cybertruck vehicles adding Tron Ares mode to the infotainment system. The update transforms the navigation display by replacing the standard vehicle icon with a Light Cycle representation from the Tron franchise complete with glowing trail effects during route guidance. Vehicles equipped with ambient lighting receive a synchronized red hue throughout the cabin enhancing the thematic experience.
The feature activates through the Toybox menu accessible via the app launcher and remains optional for users. The rollout occurs via over the air updates with no service center visits required for installation. Eligibility includes vehicles with the AMD Ryzen processor and compatible hardware.
The Tron Ares mode modifies only visual elements in the navigation interface without altering core driving functions controls or safety systems. Activation requires navigating to the Toybox section in the app launcher selecting the Tron option and confirming enablement. Once active the central display shows the Light Cycle during map views with dynamic lighting trails following the vehicle’s path. Turn signal chimes update to a thematic sound distinct from standard alerts.
Ambient lighting integration applies to supported models activating a red preset automatically when the mode engages. Users can disable the feature at any time through the same Toybox menu returning to default visualizations. The update includes minor enhancements to the dashcam viewer and side camera displays but focuses primarily on the promotional theme. Compatibility extends to all regions where the 2025.38 series deploys.
The update deploys to Model 3 vehicles produced since 2021 Model Y since 2020 and all Cybertruck models featuring the AMD Ryzen infotainment processor. Vehicles with Intel Atom systems receive the software but limited thematic effects to screen graphics only. Ambient lighting compatibility requires the premium interior package in Model 3 and Y or standard in Cybertruck. Installation occurs automatically over Wi Fi with download sizes under 2GB and installation times of 20 to 30 minutes during parked states.
No hardware modifications are needed and the feature operates alongside Full Self Driving Beta or Enhanced Autopilot. Tesla reports 99 percent successful installations across the fleet with troubleshooting available through the support app. The mode functions in all driving modes including highway and city navigation.
The update version 2025.38.3.1 includes the Tron mode alongside improvements to 3D building visualizations in navigation satellite view enhancements and dashcam viewer updates. The Light Cycle graphics render using vector based animations for smooth scaling across resolutions up to 4K. Ambient lighting syncs via the vehicle’s RGB system with 16 million color options preset to red for the theme. Processing occurs on the infotainment unit without impacting vehicle performance or battery drain.
The update weighs 1.8GB and installs during low usage periods such as overnight charging. Tesla’s over the air system ensures backward compatibility with prior versions allowing reversion if issues arise. Safety features like Autopilot visualizations remain unaffected by the theme. The implementation supports future expansions through additional Toybox entries.
