How Speed Assist Works
Model S displays a speed limit on the
instrument panel and you can choose if and
how you are warned when you exceed the
speed limit. Also, instead of using the
detected speed limit, you can base warnings
on an arbitrary speed limit that you enter
manually.
NOTE:
On roads where the map data
determines that a conditional speed limit
exists (for example, a speed limit based on
time of day or weather conditions), a second
speed limit displays below the first speed
limit. It is the driver's responsibility to
determine whether the conditional speed
limit is currently in effect and adjust the
driving speed accordingly. You may need to
update the onboard maps to display
).
In situations where Model S is unable to
determine a speed limit, or if Speed Assist is
uncertain that an acquired speed limit is
accurate, 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
Controlling Speed Assist on page 124
)
and exceed the determined speed limit, the
speed limit sign on the instrument panel
increases in size.
If you set the speed limit warning to
Chime
(see
Controlling Speed Assist on page 124
and exceed the determined speed limit, the
speed limit sign on the instrument panel
increases in size and Model S also sounds a
warning chime.
NOTE:
Speed limit warnings go away after ten
seconds, or when Model S 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 traffic
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:
•
Off
- Speed limit warnings do not display
and chimes are not sounded.
•
Display
- Speed limit signs display on the
instrument panel 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 offset
(
+
or
-
) if you want to be alerted only
when you exceed the offset speed limit by
a specified amount. For example, you can
increase the offset to +10 km/h if you only
want to be warned when you exceed the
speed limit by 10 km/h.
NOTE:
The offset from speed limit also
affects the number shown in the gray
speedometer icon on the left side of the
driving speed on the instrument panel.
•
Absolute
- Manually specify any speed
limit between 30 and 240 km/h.
