Tesla MODEL S 2012 - Traffic Light and Stop Sign Control

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 S 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 S
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 S stops at the red line displayed on the
instrument panel'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 76) and
calibrated (see
Drive to Calibrate Cameras on page
75). 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 S. 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 128).
• 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 instrument panel 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 S slows down and displays a red
line to indicate where
Model S will stop. To continue
through the intersection—even if the trac light is green
—you must pull the Autopilot stalk toward you 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 S continues through the intersection and resumes
your set cruising speed.
NOTE: If Model S is approaching a green light and
detects that a vehicle in front of you is continuing
through the intersection, Model S continues 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 pull the Autopilot stalk toward you 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 S may determine that it is not
appropriate to proceed. Therefore, Model S 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:
Trac Light and Stop Sign Control
DOES NOT turn Model S through an intersection.
When in a turning lane, Model S stops at the red
stop line. To proceed, pull the Autopilot stalk
toward you or briefly press the accelerator pedal—
Model S continues straight through the
intersection (even when in a turning lane), so you
MUST manually steer Model S through the
intersection (which cancels Autosteer).
Trac Light and Stop Sign Control is designed to
operate as described only when the following conditions
are met:
• Autosteer or Trac-Aware Cruise Control is engaged.
•
The cameras can detect an upcoming trac light,
stop sign or road marking (for example, cameras are
unobstructed and have a clear line-of-sight to the
trac light, stop sign, or road marking).
