Lane Assist
The Autopilot cameras and ultrasonic sensors
monitor the markers on the lane you are
driving in as well as the areas surrounding
Model S for the presence of vehicles 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 your vehicle 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) represent the object's
proximity to your vehicle, with white being the
farthest and red being very close, 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 trac).
Lane Assist also warns you when a desired
lane departure is not appropriate. When you
engage the turn signal and a vehicle or object
is detected in the adjacent lane you are
planning to move into, the instrument panel
displays a red lane line to indicate that a
vehicle or object is detected. When the vehicle
or object is no longer detected, the lane line
returns to normal.
Warning:
Lane Assist features are for
guidance purposes only and are not
intended to replace your own direct visual
checks. Before changing lanes, always
visually check the lane you are moving
into by using side mirrors and performing
the appropriate shoulder checks.
Warning: Never depend on Lane Assist to
inform you of unintentionally driving
outside of the driving lane, or informing
you that a vehicle is in your blind spot or
close to the side of your vehicle. Several
external factors can reduce the
performance of Lane Assist such as a lack
of lane markings or curbs. This may result
in false, or lack of, warnings (see
Limitations and Inaccuracies on page
111). 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.
Lane Assist also consists of the following
features to assist you in staying safe in the
driving lanes:
• Lane Departure Avoidance
• Emergency Lane Departure Avoidance
• Blind Spot Collision Warning Chime
Lane Departure Avoidance
Depending on your vehicle's configuration,
this feature may not be available.
Lane Departure Avoidance provides steering
interventions if Model S drifts into (or close to)
an adjacent lane when driving between 40
and 90 mph (64 and 145 km/h) on major
roadways with clearly visible lane markings.
Touch Controls > Autopilot > Lane Departure
Avoidance and choose:
• OFF: You are not warned of lane
departures or potential collisions with a
vehicle in an adjacent lane.
• WARNING: The steering wheel vibrates if a
front wheel passes over a lane marking
while the associated turn signal is o. A
visual warning on the instrument panel is
also displayed.
• ASSIST: In addition to the steering wheel
vibration and a visual warning, Model S
attempts to steer to a safer position in its
driving lane if the vehicle detects drifting
or a potential collision while the
associated turn signal is o.
Your setting is retained until you manually
change it.
When Lane Departure Avoidance detects
drifting and applies a steering intervention,
the designated lane line is highlighted in blue
on the instrument panel.
Note: Lane Departure Avoidance is intended
to help keep you safe, but it does not work in
