2017 TESLA MODEL S Owner's Manual

How Speed Assist Works
If Model S is equipped with Autopilot
components (see About Driver Assistance on
page 65), the forward looking camera detects
speed limit signs. The signs are then analyzed
and compared against GPS data to determine
the speed limit at your current driving
location. For routes where no signs are
present, speed limits are determined using
GPS data (if available). Instead of determining
the speed limit based on signs and GPS data,
you can also manually enter an arbitrary speed limit.
When Speed Assist is turned on (described
below), the instrument panel displays a speed
limit sign. Warnings (described below) take
effect when you exceed this limit.
In situations where Speed Assist is unable to
detect a speed (for example, speed limit signs
and GPS data are not available at the current
location), or if Speed Assist is uncertain that
an acquired speed limit is accurate (for
example, although a speed limit sign was
initially detected, some time has passed
before a subsequent sign has been detected), the instrument panel may not display a speed
limit sign and warnings do not take
effect.
If you set the speed limit warning to Display
(see Controlling Speed Assist on page 88),
the speed limit sign on the instrumental panel
increases in size whenever you exceed the
speed limit.
If you set the speed limit warning to Chime (see Controlling Speed Assist on page 88)
and exceed the speed limit, you also hear a warning chime.
Note: Speed limit warnings go away after 10 seconds, or when Model S slows down below
the
specified limit.
Warning: Do not rely on Speed Assist to
determine the appropriate speed limit. Always drive at a safe speed based on
traffic and road conditions.
Controlling Speed Assist
