Intelligent Speed Assist
How Intelligent Speed Assist Works
Model 3 displays a speed limit on the touchscreen and warns you if the vehicle exceeds the speed limit. The audible speed limit warnings can be muted every drive cycle but not disabled.
Excludes United Kingdom, Northern Ireland, Iceland, Turkey, Israel: A chime sounds when you exceed the determined speed limit and the speed limit sign flashes.
Note
For every occurrence, the speeding chime goes away after few seconds, or when Model 3 slows down below the specified limit using the brake pedal.
Pressing the speed limit sign on the touchscreen mutes the speeding chime and display for the rest of the drive. The speeding warnings automatically re-enable at the start of every drive cycle (every time the vehicle is in Park and you walk away).
Only in United Kingdom, Northern Ireland, Iceland, Turkey, Israel: Appears when you exceed the determined speed limit and the speed limit sign flashes.
Indicates an assumed speed limit.
When persistent, Intelligent Speed Assist is unavailable.
Warning
Do not rely on Intelligent Speed Assist to determine the appropriate speed limit or driving speed. Always drive at a safe speed based on traffic and road conditions.
Note
Your vehicle is continuously upgraded through over-the-air software updates. Download updates as soon as they become available (see Software Updates and Map Updates).
Limitations and Inaccuracies
Intelligent Speed Assist may not be fully functional or may provide inaccurate information in these situations:
- Visibility is poor and speed limit signs are not clearly visible (due to heavy rain, snow, fog, etc.).
- Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
- Model 3 is being driven very close to a vehicle in front of it which is blocking the view of the camera(s).
- The windshield is obstructing the view of the camera(s) (fogged over, dirty, covered by a sticker, etc.).
- Speed limit signs are concealed by objects.
- The speed limits stored in the map database are incorrect or outdated.
- Traffic signs that do not conform to standard recognizable formats, such as digital or temporary speed signs.
- A road or a speed limit has recently changed.
Warning
The list above does not represent an exhaustive list of situations that may interfere with proper operation of Intelligent Speed Assist. Intelligent Speed Assist may fail to provide warnings for many other reasons.
