Speed Assist
Always drive at a safe speed based on
traffic and road conditions.
•
•
•
Bright light (oncoming headlights or
direct sunlight) is interfering with the
camera's view.
Model S is being driven very close to a
vehicle in front of it which is blocking the
camera's view.
The windshield area in the camera's field
of view is obstructed (fogged over, dirty,
covered by a sticker, etc.).
Speed limit signs are concealed by
objects.
The speed limits stored in the GPS
database are incorrect or outdated.
Model S is being driven in an area where
GPS data is not available.
Traffic signs do not conform to standard
recognizable formats.
A road or a speed limit has recently
changed.
Caution: If your Model S is equipped with
Speed Assist, you must take your vehicle
to Tesla Service if a windshield
replacement is needed. Failure to do so
can cause Speed Assist to malfunction.
Controlling Speed Assist
•
•
•
•
•
To turn Speed Assist on or off, and control
how it works, touch Controls > Settings >
Driver Assistance > Assistance Level, then
choose an assistance level:
•
•
Off. The speed limit is not displayed.
Display. Speed limit information visually
displays on the speedometer and when
you exceed the limit, a speed limit sign
displays in the center of the instrument
panel, and the speedometer displays the
excess speed in gray.
•
Chime. In addition to the visual display, an
audible chime sounds whenever you
exceed the speed limit.
You can also specify how the speed limit is
determined:
•
Relative. The speed limit is determined
automatically based on detected traffic
signs and GPS data. If desired, you can set
a speed limit offset (+ or -) if you want to
be alerted only when you exceed the
speed limit by a specified amount. For
example, you would increase the offset to
+10
mph if you only want to be alerted
when you exceed the speed limit by
10
mph.
•
Absolute. Manually specify any speed limit
between 20 and 140 mph (30 and
240
km/h).
Note: GPS data is not always accurate. The
GPS can misjudge the road's location and
provide the speed limit for a directly adjacent
road that may have a different speed limit. For
example, The GPS can assume Model S is on a
freeway when it’s actually on a nearby surface
street, and vice versa.
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.).
