2014 Tesla Model S Owners Manual North America

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database are incorrect or outdated.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.).
