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
different speed limit. For example, Speed
Assist can assume Model S 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. It is also saved in
your driver profile.
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 S 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database are incorrect or outdated.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 S is being driven in an area where
GPS or map data is not available.
• Traffic signs do not conform to standard
recognizable formats.
• 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.
