NOTE: In low light conditions (dusk or dark), Autosteer
aborts or is unavailable if headlights are set to
Off. For
best results, set headlights to
Auto.
If unable to detect lane markings, Autosteer may determine the driving lane based on a vehicle you are
following.
In most cases, Autosteer attempts to center Model X in
the driving lane. However, there may be situations in which Autosteer may steer
Model X in a driving path
that is
offset from the center of the lane (for example,
detection of guard rails).
WARNING: Autosteer is not designed to, and will
not, steer Model X around objects partially in a
driving lane and in some cases, may not stop for
objects that are completely blocking the driving
lane. Always watch the road in front of you and
stay prepared to take immediate action. It is the
driver

In situations where Auto Lane Change is unable to operate at optimal performance, or cannot operate due to inadequate data, the
instrument panel displays a
series of warnings. Therefore, when using Auto Lane
Change, always pay attention to the
instrument panel
and be prepared to manually steer Model X.
Adjacent Lane Speed
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Adjacent Lane
Speed, or the feature may not operate exactly as
described.
When moving significantly faster than vehicles in
adjacent lanes,
Model X automatically reduces the
driving speed. This is especially helpful in heavy
traffic
situations or when vehicles are constantly merging into
different lanes. When Model X detects other vehicles
driving
significantly slower, the instrument panel
highlights the adjacent lanes with arrows and detected
vehicles in gray, and
Model X reduces the driving speed
as appropriate. To temporarily override this feature,
press the accelerator pedal.
WARNING: Never depend on Autopilot to
determine a safe driving speed; you are
responsible for driving safely and according to
traffic laws in your market region.
Stop Light and Stop Sign Warning
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Stop Light and
Stop Sign Warning, or the feature may not operate
exactly as described.
While Autosteer is in use, Model X displays a warning on
the
instrument panel and sounds a chime if it detects
that you are likely to run through a red stop light or stop sign. If this happens,
TAKE IMMEDIATE CORRECTIVE
ACTION!
The visual and audible warnings cancel after a few seconds, or when you press the brake pedal, whichever
comes
first.
Stop Light and Stop Sign Warning provides warnings
only. It does not slow down or stop
Model X at red traffic
lights, stop signs, road markings, etc. If equipped with
Traffic Light and Stop Sign Control, you can enable this
feature to automatically stop Model X at traffic lights
and stop signs (see Traffic Light and Stop Sign Control
on page 113).
CAUTION: Stop Light and Stop Sign Warning
requires on-board maps to know that a particular
stop light or stop sign exists at a location. In some
cases, map data is inaccurate or outdated and may
not include all stop lights or stop signs. Therefore,
Stop Light and Stop Sign Warning may not detect
all stop lights and stop signs.
WARNING: The Stop Light and Stop Sign Warning
feature does not apply the brakes or decelerate
Model X and may not detect all stop lights and
stop signs. Stop Light and Stop Sign Warning is
designed for guidance purposes only and is not a
substitute for attentive driving and sound
judgment. Keep your eyes on the road when
driving and never depend on Stop Light and Stop
Sign Warning to warn you of a stop light or stop
sign.
WARNING: Stop Light and Stop Sign Warning is
designed to warn you only when approaching a
visible red stop sign, solid red or later portion of a
yellow traffic light. It may not warn you of
intersections with flashing lights and it does not
warn you of yield signs or temporary stop and
yield signs (such as those used in construction
areas). Additionally, Stop Light and Stop Sign
Warning does not warn you of approaching stop
lights or stop signs when you are pressing the
accelerator pedal or brake pedal (which disables
Autosteer).
Limitations
Autosteer and its associated functions are particularly
unlikely to operate as intended when:

NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Traffic Light and
Stop Sign Control, or the feature may not operate
exactly as described.
NOTE: Traffic Light and Stop Sign Control is a BETA
feature and works best on roads that are frequently
driven by Tesla vehicles. Traffic Light and Stop Sign
Control attempts to stop at all traffic lights and may also
stop at green lights.
Traffic Light and Stop Sign Control is designed to
recognize and respond to
traffic lights and stop signs,
slowing
Model X to a stop when using Traffic-Aware
cruise control or Autosteer. This feature uses the

Traffic Lights
When driving with Autosteer or Traffic-Aware Cruise Control engaged, and Traffic Light and Stop Sign Control
enabled,
Model X is designed to respond as follows when approaching intersections controlled by a traffic light:
Type of Traffic LightVehicle Intended Response
At a solid green traffic light, or at a traffic light that is currently off (not
illuminated),
Model X slows down.
If you are following a car in front of you that continues through the intersection,
the
instrument panel displays a green stop line and provided your hands are
detected on the
steering yoke (or steering wheel), Model X also continues. If a car
is not in front of you, the
instrument panel displays a red stop line and you must
confirm that you want to continue through the intersection by briefly pressing the
accelerator pedal. If you don

Stop Signs and Road Markings
When driving with Autosteer or Traffic-aware Cruise Control engaged, and Traffic Light and Stop Sign Control
enabled,
Model X is designed to respond as follows when approaching intersections controlled by stop signs, stop
lines, or road markings:
Type of IntersectionVehicle Intended Response
No Traffic Control
Arm of T-junction
Model X assumes the right of way and continues straight without slowing down or
stopping.
End of T-junction
If Model X detects a T-junction based on the map data, Model X slows down and
comes to a complete stop at the red stop line displayed on the
instrument panel.
When you want to proceed, you must take over steering and acceleration.
WARNING: Model X may not stop at a T-junction that does not have a stop
sign or stop line, or if the T-junction is not included in the map data. Drive
attentively and be prepared to stop (when necessary and/or appropriate).
Stop Sign
Model X slows down and comes to a complete stop at the red stop line displayed on
the
instrument panel. When you want to proceed through the intersection, you must
briefly press the accelerator pedal.
NOTE: If you confirm that you want to proceed through an intersection controlled by
a stop sign by
briefly pressing the accelerator pedal before Model X has stopped,
your
confirmation is ignored. Model X is not designed to proceed through a stop
sign without stopping.
NOTE: Even when using Autosteer, and even if you have engaged a turn signal, you
must turn the
steering yoke (or steering wheel) yourself (which cancels Autosteer)
to complete a turn at an intersection.

WARNING: Model X also slows down and stops at a roundabout. You must take over steering (which cancels
Autosteer) and briefly press the accelerator pedal to confirm that you want to continue through the
roundabout.
WARNING: At crosswalks, Model X may slow down and may stop, depending on whether the crosswalk is
controlled by a traffic light and whether the cameras detect pedestrians, bicyclists, etc. in the crosswalk. Pay
particular attention at crosswalks and be prepared to take over at any time. Failure to do so can result in injury
or death.
Limitations
Depending on many different circumstances and environmental conditions, Traffic Light and Stop Sign Control may

Immediately after initiating Smart Summon in either
mode, hazard lights
briefly flash, mirrors fold, and
Model X shifts into Drive or Reverse. Model X then slowly
moves to within
3 feet (1 meter) of you (COME TO ME)
or your chosen destination (GO TO TARGET), navigating obstacles as needed. As
Model X moves, the
corresponding red arrow on the map also moves to
