Tesla MODEL Y 2022 - Traffic Light and Stop Sign Control; Before Using; How it Works

NOTE: Depending on market region, vehicle
configuration, options purchased, and
software version, your vehicle may not be
equipped with Trac Light and Stop Sign
Control, or the feature may not operate
exactly as described.
NOTE: Trac Light and Stop Sign Control is a
BETA feature and works best on roads that
are frequently driven by Tesla vehicles. Trac
Light and Stop Sign Control attempts to stop
at all trac lights and may also stop at green
lights.
Trac Light and Stop Sign Control is
designed to recognize and respond to trac
lights and stop signs, slowing Model Y to a
stop when using Trac-Aware cruise control
or Autosteer. This feature uses the vehicle's
forward-facing cameras, in addition to GPS
data, and slows the car for all detected
trac
lights, including green, blinking yellow, and o
lights in addition to stop signs and some road
markings. As
Model Y approaches an
intersection, the touchscreen displays a
notification indicating the intention to slow
down. You must confirm that you want to
continue or Model Y stops at the red line
displayed on the
touchscreen's driving
visualization.
WARNING: NEVER make assumptions
and predict when and where Trac
Light and Stop Sign Control will stop
or continue through an intersection or
road marking. From a driver's
perspective, the behavior of Trac
Light and Stop Sign Control may
appear inconsistent. Always pay
attention to the roadway and be
prepared to take immediate action. It
is the driver's responsibility to
determine whether to stop or continue
through an intersection. Never depend
on Trac Light and Stop Sign Control
to determine when it is safe and/or
appropriate to stop or continue
through an intersection.
Before Using
Before using Trac Light and Stop Sign
Control, you must:
• Ensure that forward-facing cameras are
unobstructed (see Cleaning Cameras and
Sensors on page 89) and calibrated (see
Drive to Calibrate Cameras on page 88).
Trac Light and Stop Sign Control
depends on the ability of the cameras to
detect trac lights, stop signs, and road
markings.
• Ensure that the latest version of maps has
been downloaded to Model Y. Although
Trac Light and Stop Sign Control
primarily uses visual data received from
the vehicle's cameras, greater accuracy is
achieved when using the most recent
map data. To check which version of
maps is currently downloaded, touch
Controls > Software > Additional vehicle
information. You must connect to a Wi-Fi
network to receive updated maps (see
Map Updates on page 152).
•
Enable the feature. With the vehicle in
Park, touch Controls > Autopilot > Trac
Light and Stop Sign Control. Once
enabled, Trac Light and Stop Sign
Control operates whenever Trac-Aware
Cruise Control or Autosteer is active.
How it Works
When Trac Light and Stop Sign Control is
enabled and you are using Autosteer or
Trac-Aware Cruise Control, the touchscreen
displays a popup message to inform you that
an upcoming trac light, stop sign, or road
marking has been detected. As it approaches
the stop location,
even at an intersection
where the trac light is green, Model Y slows
down and displays a red line to indicate
where Model Y will stop. To continue through
the intersection—even if the
trac light is
green —you must press down on the drive
stalk or briefly press the accelerator pedal to
give the vehicle permission to proceed. When
you've
confirmed that you want to proceed,
the red stop line turns gray and
Model Y
continues through the intersection and
resumes your set cruising speed.
NOTE: If, after you press down on the drive
stalk or briefly press the accelerator pedal to
confirm that you want to continue through
the intersection, the
trac signal changes
before you enter the intersection (for
example, the light changes from green to
yellow or from yellow to red),
Model Y may
determine that it is not appropriate to
proceed. Therefore,
Model Y stops and you
must press the accelerator to proceed. At all
times, it is your responsibility to ensure the
vehicle stops or accelerates appropriately and
safely.
