NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Trac Light and
Stop Sign Control, or the feature may not operate
exactly as described.
NOTE: Trac Light and Stop Sign Control is a BETA
feature and works best on roads that are frequently
driven by Tesla vehicles. Trac Light and Stop Sign
Control attempts to stop at all trac lights and may also
stop at green lights.
Trac Light and Stop Sign Control is designed to
recognize and respond to
trac lights and stop signs,
slowing Model X to a stop when using Trac-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
trac lights,
including green, blinking yellow, and o lights in addition
to stop signs and some road markings. As Model X
approaches an intersection, the instrument panel
displays a notification indicating the intention to slow
down. You must confirm that you want to continue or
Model X stops at the red line displayed on the
instrument panel's driving visualization.
WARNING:
NEVER make assumptions and predict
when and where Trac Light and Stop Sign
Control will stop or continue through an
intersection or road marking. From a driver's
perspective, the behavior of Trac 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 Trac 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 Trac Light and Stop Sign Control, you
must:
•
Ensure that forward-facing cameras are unobstructed
(see Cleaning Cameras and Sensors on page 100)
and calibrated (see
Drive to Calibrate Cameras on
page 99). Trac Light and Stop Sign Control
depends on the ability of the cameras to detect
trac lights, stop signs, and road markings.
• Ensure that the latest version of maps has been
downloaded to
Model X. Although Trac 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 169).
• Enable the feature. With the vehicle in Park, touch
Controls > Autopilot > Trac Light and Stop Sign
Control. Once enabled, Trac Light and Stop Sign
Control operates whenever Trac-Aware Cruise
Control or Autosteer is active.
How it Works
When Trac Light and Stop Sign Control is enabled and
you are using Autosteer or
Trac-Aware Cruise Control,
the instrument panel displays a popup message to
inform you that an upcoming trac light, stop sign, or
road marking has been detected. As it approaches the
stop location,
even at an intersection where the trac
light is green, Model X slows down and displays a red
line to indicate where
Model X will stop. To continue
through the intersection—even if the trac light is green
—you must 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 X continues through the
intersection and resumes your set cruising speed.
NOTE: If Model X is approaching a green light and
detects that a vehicle in front of you is continuing
through the intersection, Model X continues through the
intersection without requiring your confirmation,
provided you are not in a turning lane and your hands
are detected on the
steering yoke (or steering wheel).
NOTE: If, after you briefly press the accelerator pedal to
confirm that you want to continue through the
intersection, the trac signal changes before you enter
the intersection (for example, the light changes from
green to yellow or from yellow to red),
Model X may
determine that it is not appropriate to proceed.
Therefore, Model X 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.
WARNING:
Trac Light and Stop Sign Control
DOES NOT turn Model X through an intersection.
When in a turning lane, Model X stops at the red
stop line. To proceed, briefly press the accelerator
pedal—Model X continues straight through the
intersection (even when in a turning lane), so you
MUST manually steer Model X through the
intersection (which cancels Autosteer).
Trac Light and Stop Sign Control is designed to
operate as described only when the following conditions
are met:
• Autosteer or Trac-Aware Cruise Control is engaged.
• The cameras can detect an upcoming trac light,
stop sign or road marking (for example, cameras are
unobstructed and have a clear line-of-sight to the
trac light, stop sign, or road marking).
