Active Safety Features; Lane Assist - Tesla X 2015 Owner's Manual

Lane Assist

Model X monitors the markers on the lane you are
driving in as well as the surrounding areas for the
presence of vehicles or other objects.
When an object is detected in your blind spot or near
the side of Model X (such as a vehicle, guard rail, etc.),
the instrument panel displays colored lines radiating
from the image of your vehicle. 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 Model X, with white
being the farthest and red being the closest 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 X is at a standstill (for example, in heavy traffic).
CAUTION: Ensure all cameras and sensors are
clean. Dirty cameras and sensors, as well as
environmental conditions such as rain and faded
lane markings, can affect Autopilot performance.
WARNING: Lane Assist features are for guidance
purposes only and is not intended to replace your
own direct visual checks. Before changing lanes,
always use side mirrors and perform the
appropriate shoulder checks to visually determine
if it is safe and appropriate to change lanes.
WARNING: Never depend on Lane Assist to inform
you if you unintentionally drive outside of the
driving lane, or to inform you that there is a vehicle
beside you or in your blind spot. Several external
factors can reduce the performance of Lane Assist
(see Limitations and Inaccuracies on page
is the driver's responsibility to stay alert and pay
attention to the driving lane and other road users.
Failure to do so can result in serious injury or
death.

Steering Interventions
Lane Assist provides steering interventions if Model X
drifts into (or close to) an adjacent lane in which an
object, such as a vehicle, is detected. In these situations,
Model X automatically steers to a safer position in the
driving lane. This steering is applied only when Model X
is traveling between 30 and 85 mph (48 and 140 km/h)
on major roads with clearly visible lane markings. When
a steering intervention is applied, the instrument panel
briefly displays a warning message.
Lane Departure Avoidance
Lane Departure Avoidance is designed to warn you if
Model X is drifting out of, or nears the edge of, your
driving lane.
Lane Departure Avoidance operates when driving
between 40 and 90 mph (64 and 145 km/h) on roads
with clearly visible lane markings. You can choose if and
how you want Lane Departure Warning to operate by
touching Controls > Autopilot > Lane Departure
Avoidance and selecting between these options:
• Off: You are not warned of lane departures or
potential collisions with a vehicle in an adjacent lane.
• Warning: If a front wheel passes over a lane marking,
the steering wheel vibrates.
• Assist: Corrective steering is applied to keep Model X
in a safe position if Model X drifts into an adjacent
lane or near the edge of the road.
When Lane Departure Avoidance is enabled and Traffic-
Aware Cruise Control is active, if Model X drifts out of
the driving lane when the associated turn signal is off,
Lane Assist also checks to see whether your hands are
on the steering wheel. If hands are not detected, the
instrument panel displays a series of alerts, similar to
those that are used when driving with Autosteer. If
hands are repeatedly not detected Model X gradually
slows down to 15 mph (25 km/h) below the detected
speed limit, or below the set cruising speed, and the
hazard lights start flashing.
NOTE: Lane Departure Avoidance does not warn you of
lane departures, or provide steering interventions, if the
associated turn signal is on, which indicates an
intentional lane change.
WARNING: Lane Departure Avoidance is intended
to help keep you safe, but it does not work in
every situation and does not replace the need to
125). It
remain attentive and in control.
WARNING: Keep your hands on the steering wheel
and drive attentively at all times.
WARNING: Steering interventions are minimal and
are not designed to move Model X out of its
driving lane. Do not rely on steering interventions
to avoid side collisions.
