Tesla Model Y: Controlling Speed Assist

Tesla Model Y (2020-2025) Owner's Manual / Active Safety Features / Speed Assist / Controlling Speed Assist

To adjust the Speed Limit Warning setting, touch Controls > Autopilot > Speed Limit Warning, then choose one of these options:

  • Off - Speed limit warnings do not display and chimes are not sounded.
  • Display - Speed limit signs display on the instrument panel and the sign increases in size when you exceed the determined limit.
  • Chime - In addition to the visual display, a chime is sounded when you exceed the determined speed limit.

You can also specify how the speed limit is determined:

  • Relative - You can set a speed limit off set (+ or -) if you want to be alerted only when you exceed the off set speed limit by a specified amount. For example, you can increase the off set to +10 mph (10 km/h) if you only want to be warned when you exceed the speed limit by 10 mph (10 km/h).
  • Absolute - Manually specify any speed limit between 20 and 140 mph (30 and 240 km/h).

NOTE: Speed Assist is not always accurate. In some situations, the location of a road can be miscalculated and Speed Assist can display a speed for a directly adjacent road that may have a different speed limit. For example, Speed Assist can assume Model Y is on a controlled-access highway when it is actually on a nearby surface street, and vice versa.

NOTE: Your chosen setting is retained until you manually change it.
