• Driving speed is at least 30 mph
(45 km/h).
As the lane change is in progress, Overtake
Acceleration is activated, allowing Model Y to
accelerate closer to a vehicle in front (see
Overtake Acceleration on page 89). Midway
through the lane change, Auto Lane Change
must detect the target lane's outside lane
marking. If this lane marking cannot be
detected, the lane change is aborted and
Model Y returns to its original driving lane.
Note: Auto Lane Change moves Model Y one
lane at a time. Moving into an additional lane
requires you to engage the turn signal a
second time after the first lane change is
complete.
When using Auto Lane Change, it is important
to monitor its performance by watching the
driving path in front of you and the
surrounding area. Stay prepared to take over
steering at any time. As you are crossing over
into the adjacent lane, the touchscreen
displays the lane marking as a dashed blue
line. Once in your new lane, lane markings are
displayed as solid blue lines again.
In situations where Auto Lane Change is
unable to operate at optimal performance, or
cannot operate due to inadequate data, the
touchscreen displays a series of warnings.
Therefore, when using Auto Lane Change,
always pay attention to the touchscreen and
be prepared to manually steer Model Y.
Stop Light and Stop Sign Warning
(U.S. only)
Depending on market region or vehicle
configuration, Stop Light and/or Stop Sign
Warning may not be available on your vehicle.
While Autosteer is in use, Model Y displays a
warning on the touchscreen 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 makes no attempt to slow
down or stop Model Y at red trac lights, stop
signs, road markings, etc.
Note: Touch Controls > Autopilot > Full Self-
Driving Visualization Preview to display more
details about the roadway and its
surroundings, such as road markings, stop
signs, stop lights, objects (such as trash cans
and poles), etc.
Caution: Stop Light and Stop Sign
Warning requires the vehicle’s map to
know that a particular stop light or stop
sign exists in a certain location. It may be
unaware of new stop lights or stop signs
that are not captured in the map data.
Therefore, Stop Light and Stop Sign
Warning may not detect all stop lights
and stop signs due to potential map
inaccuracies.
Warning: Stop Light and Stop Sign
Warning do not apply the brakes or
decelerate Model Y and may not detect
all stop lights and stop signs. Stop Light
and Stop Sign Warning are designed for
guidance purposes only and are 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 are designed to only warn you
when approaching a visible red stop sign,
solid red or later portion of a yellow
trac light; it may not issue warnings at
intersections with flashing lights and does
not warn you of yield signs or temporary
stop and yield signs (such as in
construction areas). Additionally, Stop
Light and Stop Sign Warning will not
warn you of an approaching stop light or
stop sign if 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:
• Autosteer is unable to accurately
determine lane markings. For example,
lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction, are
changing quickly (lanes branching o,
crossing over, or merging), objects or
landscape features are casting strong
shadows on the lane markings, or the road
surface contains pavement seams or other
high-contrast lines.
