Lane Assist - Tesla Model 3 Owner's Manual

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 3 (such as a
vehicle, guard rail, etc.), colored lines radiate
from the image of Model 3 on the
touchscreen. 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 3, 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 3 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,
touch Controls > Autopilot > Settings > Lane
Departure Warning. Your chosen setting is
retained until you manually change it.
Driver Assistance
In addition to the warnings described above,
Lane Assist may provide steering interventions
if Model 3 drifts into (or close to) an adjacent
lane in which an object, such as a vehicle, is
detected. In these situations, Model 3
automatically steers to a safer position in its
driving lane. This steering is applied only when
Model 3 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
touchscreen briefly displays a warning
message.
Warning: Steering interventions are
minimal and are not designed to move
Model 3 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
Inaccuracies on page 73).
Limitations and Inaccuracies
Lane Assist cannot always clearly detect lane
markings and you may experience
unnecessary or invalid warnings in these
situations:
