How Speed Assist Works
Model Y displays a speed limit on the touchscreen and you
can choose if and how you are warned when you exceed the
speed limit. In addition, a blue outline may appear around the
speed limit icon to notify that you are above the speed limit.
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 offsets that you
have set).
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 touchscreen 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.
Controlling Speed Assist
To adjust the Speed Limit Warning setting, touch Controls >
Autopilot, touch 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 touchscreen 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 offset (+ or -) if you
want to be alerted only when you exceed the offset speed
limit by a specified amount. For example, you can increase
the offset to +10 km/h if you only want to be warned when
you exceed the speed limit by 10 km/h.
•
Absolute - Manually specify any speed limit between 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.
Limitations and Inaccuracies
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.
• Model Y is being driven in an area where GPS or map data
is not available or where speed limit signs can not be
detected.
• 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 Speed Assist. Speed Assist may
fail to provide warnings for many other reasons.
