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.
Trac Light and Stop Sign Control is designed to recognize and respond to trac lights and stop signs, slowing
Model 3 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 3 approaches an intersection, the
touchscreen displays a notification indicating the intention to slow down. You must confirm that you want to
continue or Model 3 stops at the red line displayed on the touchscreen's driving visualization.
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, including green lights.
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 82) and
calibrated (see
Drive to Calibrate Cameras on page 81). 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 3. 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 > Service >
Additional vehicle information. You must connect to a Wi-Fi network to receive updated maps (see Map Updates
on page 133).
•
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
touchscreen 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 3
slows down and displays a red line to indicate where the vehicle will come to a complete stop. To continue through
the intersection—even if the trac 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 grey and Model 3 continues through the intersection and resumes your set cruising speed.
NOTE: If Model 3 is approaching a green light and detects that a vehicle in front of you is continuing through the
intersection,
Model 3 will continue through the intersection without requiring your confirmation, provided you are
not in a turning lane and your hands are detected on the steering wheel.
NOTE: If, after you press down on the drive stalk or 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 3 may determine that it is not appropriate to proceed. Therefore,
Model 3 stops and you must manually 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 WILL NOT turn Model 3 through an intersection. When in a
turning lane, Model 3 stops at the red stop line. To proceed, press down on the drive stalk or briefly press the
accelerator pedal—Model 3 will continue straight through the intersection (even when in a turning lane), so you
MUST manually steer Model 3 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:
