Speed Limit Mode: Speed Limit Mode allows you to limit acceleration and limit the maximum driving speed to a chosen value between 50 and 90 mph (80 and 145 km/h). The first time you use this feature, you must create a 4-digit PIN that you must use to enable and disable Speed Limit Mode. When enabled and the driving speed approaches within approximately 3 mph (5 km/h) of the maximum speed, a chime sounds, the instrument panel displays a message, and Model 3 sends a notification to the mobile app. To enable Speed Limit Mode:
- Ensure Model 3 is in Park.
- Touch Controls > Safety > Speed Limit Mode on the touchscreen, or touch Controls in your mobile app.
- Select the maximum driving speed.
- Drag the slider to the On position.
- Enter the 4-digit PIN that you want to use to enable and disable Speed Limit Mode.
Note
If you forget the PIN, you can disable Speed Limit Mode by entering login credentials for your Tesla account.
Note
While Speed Limit Mode is enabled, the acceleration setting (Controls > Pedals & Steering > Acceleration) automatically sets to Chill.
