Intelligent Speed Assist
How Intelligent Speed Assist Works
Model Y 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 Y 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.
Note
On roads where the map data determines that a conditional speed limit exists (for example, a speed limit based on time of day or weather conditions), a second speed limit displays below the first speed limit. It is the driver's responsibility to determine whether the conditional speed limit is currently in effect and adjust the driving speed accordingly. You may need to update the onboard maps to display conditional speed limits (Map Updates).
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).
Live Average Speed
When driving through an average speed zone, Model Y displays your average speed on the touchscreen below the detected speed limit.
The touchscreen also shows the distance remaining in the average speed zone.
Note
Premium Connectivity required. To enable this feature, enable online routing by touching (see Maps and Navigation).
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 Y 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.
