Traffic Light and Stop Sign Control
WARNING: If the touchscreen is not displaying a
red stop line at an upcoming intersection, Model Y
does not slow down or stop. It is the driver's
responsibility to pay attention to upcoming
intersections and monitor traffic conditions to
determine when and if the vehicle should stop and
then to take appropriate action as needed.
WARNING: Never depend on Traffic Light and
Stop Sign Control to determine whether to stop at,
or proceed through, an intersection. Drive
attentively by watching the road and paying
attention to the roadway, upcoming intersections,
traffic conditions, crosswalks, and other road users.
It is always the driver's responsibility to determine
whether to stop or proceed. Be prepared to take
immediate action. Failure to do so can result in
injury or death.
WARNING: In some situations, Traffic Light and
Stop Sign Control may inaccurately detect a traffic
light or stop sign, causing Model Y to slow down
unexpectedly. Be prepared to take immediate
action at all times.
WARNING: You must press down on the drive stalk
or briefly press the accelerator pedal to confirm
that you want to proceed through an intersection,
regardless of the status of the traffic light. If you
do not confirm, Model Y stops at the red stop line
displayed on the touchscreen, even if stopping
may be inappropriate. Stopping at a green light
may confuse other drivers and may result in a
collision, injury or death. Therefore, always pay
attention to upcoming intersections and be
prepared to manually brake or accelerate in
response to surroundings.
WARNING: Never assume that your ability to see a
traffic light, stop sign, or road marking (especially
at a complex intersection, or an intersection in
which a traffic light or sign is partially obstructed,
etc.) means that Model Y can also see it and
respond appropriately.
WARNING: Even the most recent map data does
not include all traffic lights and stop signs.
Therefore, Traffic Light and Stop Sign Control
relies heavily on the ability of the cameras to
detect traffic lights, stop signs, road markings, etc.
As a result, Model Y may ignore an intersection
that is blocked from the camera's view (for
example, obstructed by a tree or a large vehicle or
object, or located near a steep hill or sharp curve).
WARNING: Traffic Light and Stop Sign Control is
not a substitute for attentive driving and sound
judgment.
