Lane Assist

Steering Interventions

Model Y monitors the markers on the lane you are

driving in as well as the surrounding areas for the

presence of vehicles or other objects.

Lane Assist provides steering interventions if Model Y

drifts into (or close to) an adjacent lane in which an

object, such as a vehicle, is detected. In these situations,

Model Y automatically steers to a safer position in the

driving lane. This steering is applied only when Model Y

is traveling between 30 and 85 mph (48 and 140 km/h)

on major roads with clearly visible lane markings. When

a steering intervention is applied, the touchscreen brieﬂy

displays a warning message.

When an object is detected in your blind spot or near

the side of Model Y (such as a vehicle, guard rail, etc.),

the touchscreen displays colored lines radiating from the

image of your vehicle. The location of the lines

correspond to the location of the detected object. The

color of the lines (white, yellow, orange, or red)

represent the object's proximity to Model Y, with white

being the farthest and red being the closest and

requiring your immediate attention. These colored lines

only display when driving between approximately 7 and

85 mph (12 and 140 km/h). When Autosteer is active,

these colored lines also display if driving slower than 7

mph (12 km/h). However, the colored lines do not display

if Model Y is at a standstill (for example, in heavy traﬃc).

Lane Departure Avoidance

Lane Departure Avoidance is designed to warn you if

Model Y is drifting out of, or nears the edge of, your

driving lane.

Lane Departure Avoidance operates when driving

between 40 and 90 mph (64 and 145 km/h) on roads

with clearly visible lane markings. You can choose if and

how you want Lane Departure Warning to operate by

touching Controls > Autopilot > Lane Departure

Avoidance and selecting between these options:

• Oﬀ: You are not warned of lane departures or

potential collisions with a vehicle in an adjacent lane.

• Warning: If a front wheel passes over a lane marking,

the steering wheel vibrates.

• Assist: Corrective steering is applied to keep Model Y

in a safe position if Model Y drifts into an adjacent

lane or near the edge of the road.

When Lane Departure Avoidance is enabled and Traﬃc-

Aware Cruise Control is active, if Model Y drifts out of

the driving lane when the associated turn signal is oﬀ,

Lane Assist also checks to see whether your hands are

on the steering wheel. If hands are not detected, the

touchscreen displays a series of alerts, similar to those

that are used when driving with Autosteer. If hands are

repeatedly not detected Model Y gradually slows down

to 15 mph (25 km/h) below the detected speed limit, or

below the set cruising speed, and the hazard lights start

ﬂashing.

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: Lane Assist features are for guidance

purposes only and is not intended to replace your

own direct visual checks. Before changing lanes,

always use side mirrors and perform the

appropriate shoulder checks to visually determine

if it is safe and appropriate to change lanes.

NOTE: Lane Departure Avoidance does not warn you of

lane departures, or provide steering interventions, if the

associated turn signal is on, which indicates an

intentional lane change.

WARNING: Never depend on Lane Assist to inform

you if you unintentionally drive outside of the

driving lane, or to inform you that there is a vehicle

beside you or in your blind spot. Several external

factors can reduce the performance of Lane Assist

(see Limitations and Inaccuracies on page 120). It

is the driver's responsibility to stay alert and pay

attention to the driving lane and other road users.

Failure to do so can result in serious injury or

death.

WARNING: Lane Departure Avoidance is intended

to help keep you safe, but it does not work in

every situation and does not replace the need to

remain attentive and in control.

WARNING: Keep your hands on the steering wheel

and drive attentively at all times.

WARNING: Steering interventions are minimal and

are not designed to move Model Y out of its

driving lane. Do not rely on steering interventions

to avoid side collisions.

Emergency Lane Departure

Avoidance

Blind Spot Collision Warning Chime

If you want a chime to sound when a vehicle is in your

blind spot and a possible collision is detected, touch

Controls > Autopilot > Blind Spot Collision Warning

Chime.

Emergency Lane Departure Avoidance automatically

applies steering to avoid a potential collision in

situations where:

WARNING: Blind Spot Camera does not eliminate

the need to drive attentively and manually perform

shoulder checks when changing lanes.

• Model Y is departing a lane and may collide with a

vehicle traveling in the same direction in the adjacent

lane (regardless of the status of the turn signal).

WARNING: Blind Spot Collision Warning Chime

cannot detect every collision. It is the driver's

responsibility to remain alert and perform the

appropriate shoulder checks when changing lanes.

• Model Y is departing a lane into an oncoming lane,

the turn signal is oﬀ, and an oncoming vehicle is

detected.

• Model Y is departing the road and the turn signal is

oﬀ (for example, very close to the edge of the road

and a collision may occur).

Limitations and Inaccuracies

Lane Assist features cannot always detect lane markings

and you may experience unnecessary or invalid warnings

in these situations:

To turn this feature on or oﬀ, touch Controls > Autopilot

> Emergency Lane Departure Avoidance.

When Emergency Lane Departure Avoidance applies

steering, a chime sounds and the touchscreen displays a

warning and highlights the lane marking in red.

• Visibility is poor and lane markings are not clearly

visible (due to heavy rain, snow, fog, etc.).

• Bright light (such as from oncoming headlights or

direct sunlight) is interfering with the view of the

camera(s).

Emergency Lane Departure Avoidance operates when

Model Y is traveling between 64 and 145 km/h40 and 90

mph (64 and 145 km/h) on a road with clearly visible

lane markings, curbs, etc.

• A vehicle in front of Model Y is blocking the view of

the camera(s).

WARNING: Emergency Lane Departure Avoidance

is not a substitute for attentive driving and sound

judgment. Keep your eyes on the road when

driving and never depend on Emergency Lane

Departure Avoidance to prevent a collision. Several

factors can reduce or impair performance.

Depending on Emergency Lane Departure

Avoidance to prevent a potential collision can

result in serious injury or death.

• The windshield is obstructing the view of the

camera(s) (fogged over, dirty, covered by a sticker,

etc.).

• Lane markings are excessively worn, have visible

previous markings, have been adjusted due to road

construction, or are changing quickly (for example,

lanes branching oﬀ, crossing over, or merging).

• The road is narrow or winding.

• Objects or landscape features are casting strong

shadows on lane markers.

Automatic Blind Spot Camera

Lane Assist may not provide warnings, or may apply

inappropriate warnings, in these situations:

To display the image from the corresponding side

repeater camera whenever you engage a turn signal to

change lanes, touch Controls > Autopilot > Automatic

Blind Spot Camera.

• One or more of the sensors (if equipped) or cameras

is damaged, dirty, or obstructed (by mud, ice, or

snow, or by a vehicle bra, excessive paint, or adhesive

products such as wraps, stickers, rubber coatings,

etc.).

When the turn signal is engaged and the touchscreen is

displaying the image from the side repeater camera, you

can move the image to a diﬀerent location on the

touchscreen. To do so, touch and drag the image to the

new location (valid locations are indicated by shaded

areas that display when you touch and hold the image).

• Weather conditions (heavy rain, snow, fog, or

extremely hot or cold temperatures) are interfering

with sensor operation.

WARNING: Automatic Blind Spot Camera does not

eliminate the need to drive attentively and

manually perform shoulder checks when changing

lanes.

• The sensors (if equipped) are aﬀected by other

electrical equipment or devices that generate

ultrasonic waves.

• An object that is mounted to Model Y is interfering

with and/or obstructing a sensor (such as a bike rack

or a bumper sticker).

In addition, Lane Assist may not steer Model Y away

from an adjacent vehicle, or may apply unnecessary or

inappropriate steering, in these situations:

• You are driving Model Y on sharp corners or on a

curve at a relatively high speed.

• Bright light (such as from oncoming headlights or

direct sunlight) is interfering with the view of the

camera(s).

• You are drifting into another lane but an object (such

as a vehicle) is not present.

• A vehicle in another lane cuts in front of you or drifts

into your driving lane.

• Model Y is not traveling within the speeds at which

the Lane Assist feature is designed to operate.

• One or more of the sensors (if equipped) is damaged,

dirty, or obstructed (such as by mud, ice, or snow, or

by a vehicle bra, excessive paint, or adhesive

products such as wraps, stickers, rubber coating,

etc.).

• Weather conditions (heavy rain, snow, fog, or

extremely hot or cold temperatures) are interfering

with sensor operation.

• The sensors (if equipped) are aﬀected by other

electrical equipment or devices that generate

ultrasonic waves.

• An object mounted to Model Y (such as a bike rack or

a bumper sticker) is interfering with or obstructing a

sensor.

• Visibility is poor and lane markings are not clearly

visible (due to heavy rain, snow, fog, etc.).

• Lane markings are excessively worn, have visible

previous markings, have been adjusted due to road

construction or are changing quickly (for example,

lanes branching oﬀ, crossing over, or merging).

WARNING: The lists above do not represent every

possible situation that may interfere with Lane

Assist features. There are many reasons why Lane

Assist may not operate as intended. To avoid a

collision, stay alert and always pay attention to the

road so you can anticipate the need to take

corrective action as early as possible.
