Get Autopilot -> Traffic Light and Stop Sign Control Guide for Tesla Model-Y SUV 2023

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 Traﬃc Light and

Stop Sign Control, or the feature may not operate

exactly as described.

• Enable the feature. With the vehicle in Park, touch

Controls > Autopilot > Traﬃc Light and Stop Sign

Control. Once enabled, Traﬃc Light and Stop Sign

Control operates whenever Traﬃc-Aware Cruise

Control or Autosteer is active.

NOTE: Traﬃc Light and Stop Sign Control is a BETA

feature and works best on roads that are frequently

driven by Tesla vehicles. Traﬃc Light and Stop Sign

Control attempts to stop at all traﬃc lights and may also

stop at green lights.

How it Works

When Traﬃc Light and Stop Sign Control is enabled and

you are using Autosteer or Traﬃc-Aware Cruise Control,

the touchscreen displays a popup message to inform

you that an upcoming traﬃc light, stop sign, or road

marking has been detected. As it approaches the stop

location, even at an intersection where the traﬃc 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 traﬃc 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.

Traﬃc Light and Stop Sign Control is designed to

recognize and respond to traﬃc lights and stop signs,

slowing Model Y to a stop when using Traﬃc-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 traﬃc lights,

including green, blinking yellow, and oﬀ 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.

NOTE: If Model Y is approaching a green light and

detects that a vehicle in front of you is continuing

through the intersection, Model Y 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.

WARNING: NEVER make assumptions and predict

when and where Traﬃc Light and Stop Sign

Control will stop or continue through an

intersection or road marking. From a driver's

perspective, the behavior of Traﬃc 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 Traﬃc Light and

Stop Sign Control to determine when it is safe

and/or appropriate to stop or continue through an

intersection.

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 traﬃc

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.

Before Using

Before using Traﬃc Light and Stop Sign Control, you

must:

WARNING: Traﬃc Light and Stop Sign Control

DOES NOT turn Model Y through an intersection.

When in a turning lane, Model Y stops at the red

stop line. To proceed, press down on the drive

stalk or brieﬂy press the accelerator pedal—Model

Y continues straight through the intersection (even

when in a turning lane), so you MUST manually

steer Model Y through the intersection (which

cancels Autosteer).

• Ensure that forward-facing cameras are unobstructed

(see Cleaning Cameras and Sensors on page 90) and

calibrated (see Drive to Calibrate Cameras on page

89). Traﬃc Light and Stop Sign Control depends on

the ability of the cameras to detect traﬃc lights, stop

signs, and road markings.

• Ensure that the latest version of maps has been

downloaded to Model Y. Although Traﬃc 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 158).

Traﬃc Light and Stop Sign Control is designed to

operate as described only when the following conditions

are met:

• Autosteer or Traﬃc-Aware Cruise Control is engaged.

• The cameras can detect an upcoming traﬃc light,

stop sign or road marking (for example, cameras are

unobstructed and have a clear line-of-sight to the

traﬃc light, stop sign, or road marking).

Traﬃc Light and Stop Sign Control

• The touchscreen on Model Y is displaying an

upcoming traﬃc light in "bold" format. Model Y does

not acknowledge traﬃc lights that the touchscreen

shows as faded. If a traﬃc light is not directly ahead

of the camera (for example, it is located at an angle

of the camera's view, or located in an adjacent lane)

the touchscreen displays it as faded and Model Y

does not slow down and stop for it.

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.

Traﬃc Lights

When driving with Autosteer or Traﬃc-Aware Cruise Control engaged, and Traﬃc Light and Stop Sign Control

enabled, Model Y is designed to respond as follows when approaching intersections controlled by a traﬃc light:

Type of Traﬃc Light

Vehicle Intended Response

At a solid green traﬃc light, or at a traﬃc light that is currently oﬀ (not

illuminated), Model Y slows down.

If you are following a car in front of you that continues through the intersection,

the touchscreen displays a green stop line and provided your hands are detected

on the steering wheel, Model Y also continues. If a car is not in front of you, the

touchscreen displays a red stop line and you must conﬁrm that you want to

continue through the intersection by pressing down on the drive stalk or brieﬂy

pressing the accelerator pedal. If you don’t conﬁrm, Model Y stops at the red stop

line.

NOTE: Model Y resumes the set cruising speed when it continues through the

intersection, taking into consideration the speed of a vehicle in front of you.

Model Y slows down and comes to a complete stop at the red stop line displayed

on the touchscreen. When you want to continue through the intersection (for

example, the light turns green again, or once Model Y has come to a complete

stop), you must press down on the drive stalk or brieﬂy press the accelerator

pedal.

Model Y slows down and comes to a complete stop at the red stop line displayed

on the touchscreen. When you want to proceed through the intersection (for

example, the light turns green again), you must press down on the drive stalk or

brieﬂy press the accelerator pedal.

NOTE: If the traﬃc light changes after you've conﬁrmed that you want to proceed

(for example, a green traﬃc light turns yellow), Model Y may stop instead of

continuing, especially if Model Y determines that it can safely stop before entering

the intersection.

NOTE: Model Y is not designed to proceed through an intersection when the traﬃc

light is red or if the light turns yellow in situations when there is adequate distance

to safely stop before entering the intersection.

NOTE: You can take over driving at any time by manually braking to cancel

Autosteer or Traﬃc-aware Cruise Control.

No Traﬃc Control

Arm of T-junction

If Model Y detects a T-junction based on the map data, Model Y slows down and

comes to a complete stop at the red stop line displayed on the touchscreen. When

you want to proceed, you must take over steering and acceleration.

WARNING: Model Y may not stop at a T-junction that does not have a stop

sign or stop line, or if the T-junction is not included in the map data. Drive

attentively and be prepared to stop (when necessary and/or appropriate).

End of T-junction

Model Y slows down and comes to a complete stop at the red stop line displayed on

the touchscreen. When you want to proceed through the intersection, you must

press down on the drive stalk or brieﬂy press the accelerator pedal.

NOTE: If you conﬁrm that you want to proceed through an intersection controlled by

a stop sign by pressing down on the drive stalk or brieﬂy pressing the accelerator

pedal before Model Y has stopped, your conﬁrmation is ignored. Model Y is not

designed to proceed through a stop sign without stopping.

NOTE: Even when using Autosteer, and even if you have engaged a turn signal, you

must turn the steering wheel yourself (which cancels Autosteer) to complete a turn

at an intersection.

WARNING: Model Y also slows down and stops at a roundabout. You must take over steering (which cancels

Autosteer) and press down on the drive stalk or brieﬂy press the accelerator pedal to conﬁrm that you want to

continue through the roundabout.

WARNING: At crosswalks, Model Y may slow down and may stop, depending on whether the crosswalk is

controlled by a traﬃc light and whether the cameras detect pedestrians, bicyclists, etc. in the crosswalk. Pay

particular attention at crosswalks and be prepared to take over at any time. Failure to do so can result in injury

or death.

Limitations

Depending on many diﬀerent circumstances and environmental conditions, Traﬃc Light and Stop Sign Control may

or may not stop at:

• Railroad crossings.

• Keep-out zones.

• Toll booths.

• Crosswalk systems.

• Yield signs or temporary traﬃc lights and stop signs (such as at construction areas).

• Miscellaneous traﬃc U-turn lights, bicycle and pedestrian crossing lights, lane availability lights, etc.

In addition, Traﬃc Light and Stop Sign Control is particularly unlikely to operate as intended, can disengage, or may

not operate, when one or more of the following conditions are present:

• Driving through consecutive light-controlled intersections that are very close to each other.

• Visibility is poor (heavy rain, snow, fog, etc.) or weather conditions are interfering with camera or sensor

operation.

Traﬃc Light and Stop Sign Control

• Bright light (such as direct sunlight) is interfering with the view of the camera(s).

• A camera is obstructed, covered, damaged, or not properly calibrated.

• Driving on a hill or on a road that has sharp curves on which the cameras are unable to see upcoming traﬃc lights

or stop signs.

• A traﬃc light, stop sign, or road marking is obstructed (for example, a tree, a large vehicle, etc.).

• Model Y is being driven very close to a vehicle in front of it, which is blocking the view of a camera.

WARNING: The limitations listed above are not an exhaustive list of reasons why Model Y may not operate as

expected. Many unforeseen circumstances can adversely impact the accurate operation of Traﬃc Light and

Stop Sign Control. Using this feature does not reduce or eliminate the need to drive attentively and

responsibly. You must be prepared to take appropriate and immediate action at all times.

Autopark

This feature may be temporarily limited or inactive until

it is enabled with a future software update for vehicles

manufactured as of approximately October 2022.

To Use Autopark

When driving, follow these steps to allow Autopark to

maneuver Model Y into a parking space:

NOTE: Depending on market region, vehicle

conﬁguration, options purchased, and software version,

your vehicle may not be equipped with Autopark.

1. While driving slowly on a public road, monitor the

touchscreen to determine when Autopark has

detected a parking space. The touchscreen will

display a parking icon if the vehicle detects a

potential parking spot.

Autopark uses data to simplify parking on public roads

by maneuvering Model Y into parallel and perpendicular

parking spaces.

CAUTION: Ensure all cameras and sensors (if

equipped) are clean. Dirty cameras and sensors, as

well as environmental conditions such as rain and

faded lane markings, can aﬀect Autopilot

performance.

WARNING: Autopark's performance depends on

the ability of the cameras and sensors (if

equipped) to determine the vehicle's proximity to

curbs, objects, and other vehicles.

WARNING: Do not use Autopark if anything, such

as a ball hitch, bike rack, or trailer, is attached to

the tow hitch. Autopark may not stop for hitches

when parking between or in front of other vehicles.

Parameters

NOTE: The parking icon appears only if the vehicle's

position and/or the circumstances of the surrounding

area are such that Autopark can determine an

appropriate driving path. If Autopark cannot

determine an appropriate path (for example, when

driving on a narrow street where moving into the

parking space causes the front of the vehicle to

extend into the adjacent lane), you can either

reposition the vehicle, ﬁnd a diﬀerent parking space,

or park manually.

Autopark detects potential parking spaces based on the

following parameters:

Perpendicular Parking

• Your driving speed must be below 8 mph (13 km/h). If

driving too fast, Autopark may not be able to

accurately detect your desired parking space.

• The parking space must be at least 7.2 feet (2.2

meters) wide.

2. Check to determine if the detected parking space is

appropriate and safe. Pull forward and stop

• The parking space must have at least three visible

lines for the vehicle to park into, such as parking lines,

road markings, or distinct curbs. Autopark may not

work in a garage, for example, without three visible

parking lines.

approximately one car length ahead of the parking

space (as you normally would when parallel parking

or when backing into a perpendicular parking space).

3. Release the steering wheel, shift Model Y into

Reverse, then touch Start Autopark on the

touchscreen.

• Autopark may not work with textured road surfaces

such as cobblestone or brick.

4. Autopark displays a message when parking is

complete.

Parallel Parking

NOTE: If you press the brake pedal when Autopark is

actively parking Model Y, the parking process pauses

until you touch Resume on the touchscreen.

• Your driving speed must be below 13 mph (21 km/h).

If driving too fast, Autopark may not be able to

accurately detect your desired parking space.

WARNING: Never depend on Autopark to ﬁnd a

parking space that is legal, suitable, and safe.

Autopark may not always detect objects in the

parking space. Always perform visual checks to

conﬁrm that a parking space is appropriate and

safe.

• There must be a vehicle in front of the space you

want to park in.

• A distinct curb or edge must be visible. Autopark

may not correctly identify the parking space if the

curb is not distinct, such as grass or dirt.

NOTE: Autopark does not operate on angled parking

spaces.
