Tesla Model Y: How Speed Assist Works

Model Y displays a speed limit on the instrument panel and you can choose if and how you are warned when you exceed the speed limit. Also, instead of using the detected speed limit, you can base warnings on an arbitrary speed limit that you enter manually.

NOTE: When using Traffic-Aware Cruise Control, you can touch this speed limit sign to change your set cruising speed to the detected speed limit (including any offset that you have set).

How Speed Assist Works

In situations where Model Y is unable to determine a speed limit, or if Speed Assist is uncertain that an acquired speed limit is accurate, the instrument panel may not display a speed limit sign and warnings do not take effect.

NOTE: Speed limit warnings go away after ten seconds, or when Model Y slows down below the specified limit.

WARNING: Do not rely on Speed Assist to determine the appropriate speed limit or driving speed. Always drive at a safe speed based on traffic and road conditions.
