Tesla Model 3 - Speed Assist; Controlling Speed Limit Warnings

How Speed Assist Works
Model 3 displays a speed limit on the touchscreen and
you can choose if and how you are warned when you
exceed the speed limit.
You can touch this speed limit
sign to automatically change the set speed to the
detected speed limit (including any osets that you
have set). Also, instead of using the detected speed
limit, you can base warnings on an arbitrary speed limit
that you enter manually.
In situations where Model 3 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
eect.
If you set the speed limit warning to Display (see
Controlling Speed Assist on page 116) and exceed the
determined speed limit, the speed limit sign on the
touchscreen increases in size.
If you set the speed limit warning to Chime (see
Controlling Speed Assist on page 116) and exceed the
determined speed limit, the speed limit sign on the
touchscreen increases in size and Model 3 also sounds a
warning chime.
NOTE: Speed limit warnings go away after ten seconds,
or when
Model 3 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
trac and road conditions.
Controlling Speed Assist
To adjust the Speed Limit Warning setting, touch
Controls > Autopilot > Speed Limit Warning, then
choose one of these options:
• O - 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 whenever you exceed the determined speed
limit.
You can also specify how the speed limit is determined:
• Relative - You can set a speed limit oset (+ or -) if
you want to be alerted only when you exceed the
oset speed limit by a specified amount. For
example, you can increase the
o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. A road's
location can be miscalculated and instead Speed Assist
can display a speed for a directly adjacent road that may
have a dierent speed limit. For example, Speed Assist
can assume
Model 3 is on a freeway or 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 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.
•
Model 3 is being driven in an area where GPS or map
data is not available or where speed limit signs can
not be detected.
