Speed Limit Mode allows you to limit acceleration and limit the maximum driving speed to a chosen value between 50 and 120 mph (80 and 193 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 cluster displays a message, and Model S sends a notification to the mobile app. You can also touch Security > Speed Limit Mode to enable from the Tesla mobile app. To enable Speed Limit Mode:
1. Ensure Model S is in Park.
2. Touch Controls > Safety > Speed Limit Mode on the touchscreen.
3. Select the maximum driving speed.
4. Drag the slider to the On position.
5. 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.
WARNING: Driving downhill can increase driving speed and cause Model S 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 speed limits and driving conditions. Accidents occur at any speed.
