To further personalize Model 3, you can name it. The name of your Model 3 appears in the mobile app. To name your vehicle, touch the Tesla "T" at the top center of the touchscreen, then touch Name Your Vehicle (or touch the vehicle's existing name). Enter the new name in the popup, then touch Save.
Speed Limit Mode
Speed Limit Mode allows you to limit the acceleration and maximum speed - between 50 and 90 mph (80 and 145 km/h) - of your Model 3. This feature is protected by a 4-digit PIN that you create when enabling it for the first time, and which must be entered whenever you want to disable and enable it.
If your Model 3 comes within approximately 3 mph (5 km/h) of the selected maximum speed, a chime sounds and text appears on the touchscreen above the driving speed. Additionally, your mobile app sends you a notification.
To enable Speed Limit Mode:
Note: If you forget the PIN, you can disable Speed Limit Mode by entering the login credentials for your Tesla Account.
Note: When Speed Limit Mode is enabled, the acceleration setting (Controls > Driving > Acceleration) is automatically set to Chill.
Warning: Driving downhill can increase driving speed, causing the vehicle to exceed your chosen maximum speed.
Warning: Speed Limit Mode is not a replacement for good judgment, driver training, and the need to closely monitor roadway speed limits and driving conditions. Accidents can occur at any speed.
Erasing Personal Data
You can erase all personal data (saved addresses, music favorites, HomeLink programming, etc.) and restore all customized settings to their factory defaults. This is useful when transferring ownership of Model 3. Touch Controls > Service > FACTORY RESET. Before erasing, Model 3 verifies your credentials by prompting you to enter the user name and password associated with your Tesla Account.
