If your Model S is equipped with Driver
Assistance components (see
on page 73), the cameras monitor
the markers on the lane you are driving in and
the ultrasonic sensors monitor the
surrounding areas and the blind spot for the
presence of a vehicle or other objects.
When an object is detected in your blind spot
or close to the side of Model S (such as a
vehicle, guard rail, etc.), colored lines radiate
from the image of Model S on the instrument
panel. The location of the lines correspond to
the location of the detected object. The color
of the lines (white, yellow, orange, or red)
represents the object's proximity to Model S,
with white being the farthest and red being
very close and requiring your immediate
attention. These colored lines only display
when driving between approximately 7 and 85
mph (12 and 140 km/h). When Autosteer is
active, these colored lines also display if
driving slower than 7 mph (12 km/h). However,
the colored lines do not display if Model S is at
a standstill (for example, in heavy traffic).
Lane Assist also warns you of undesired lane
departures by vibrating the steering wheel
slightly if a front wheel passes over a lane
marking and the associated turn signal is off.
This warning is active only when driving
between approximately 36 and 90 mph (59
and 150 km/h). To turn this warning on or off,

. Your
chosen setting is retained until you manually
change it. It is also saved in your driver profile.
In addition to the warnings described above,
Lane Assist may provide steering interventions
if Model S drifts into (or close to) an adjacent
lane in which an object, such as a vehicle, is
detected. In these situations, Model S
automatically steers to a safer position in its
driving lane. This steering is applied only when
Model S is traveling between 30 and 85 mph
(48 and 140 km/h) on major roadways with
clearly visible lane markings. When Lane
Assist applies a steering intervention, the
instrument panel briefly displays a warning
message.
Warning:
Steering interventions are
minimal and are not designed to move
Model S out of its driving lane. Do not rely
on steering interventions to avoid side
collisions.
Warning:
Lane Assist features are for
guidance purposes only and are not
intended to replace your own direct visual
checks. Never depend on Lane Assist to
inform you of unintentionally driving
outside of the boundaries of the driving
lane or informing you that an object or
vehicle is in your blind spot or close to
the side of your vehicle. Several external
factors can reduce the performance of
Lane Assist. It is the driver's responsibility
to stay alert, pay attention to the driving
lane and always be aware of other road
users. Failure to do so can result in
serious injury or death.
Warning:
Lane Assist is designed to
detect lane markings and may not detect
the edge of a road, especially if the road
has no curb. It is the driver's responsibility
to drive attentively and stay within the
boundaries of the driving lane.
Warning:
Before changing lanes, always
visually check the lane you are moving
into by using side mirrors and performing
the appropriate shoulder checks. Several
factors can affect the performance of the
Lane Assist warnings, resulting in lack of,
or false warnings (see
Limitations and Inaccuracies
Lane Assist cannot always clearly detect lane
markings and you may experience
unnecessary or invalid warnings in these
situations:
