Braking SystemsWARNING: Properly functioning braking systems
are critical to ensure safety. If you experience a
problem with the brake pedal, brake calipers, or
any component of a Model Y braking system,
contact Tesla immediately.
Model Y has an anti-lock braking system (ABS) that
prevents the wheels from locking when you apply
maximum brake pressure. This improves steering control
during heavy braking in most road conditions.
During emergency braking conditions, the ABS
constantly monitors the speed of each wheel and varies
the brake pressure according to the grip available.
The alteration of brake pressure can be felt as a pulsing sensation through the brake pedal. This demonstrates that the ABS is operating and is not a cause for concern. Keep
firm and steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator briefly flashes amber on
the
touchscreen when you first start Model
Y. If this indicator lights up at any other
time, an ABS fault has occurred and the ABS is not operating. Contact Tesla. The
braking system remains fully operational
and is not
affected by an ABS failure.
However, braking distances may increase. Drive cautiously and avoid heavy braking.
If the touchscreen displays this red brake
indicator at any time other than
briefly

when you first start Model Y, a brake
system fault is detected, or the level of the
brake
fluid is low. Contact Tesla
immediately. Apply steady pressure and
keep the brakes
firm to bring the vehicle to
a stop when safe to do so.
The touchscreen displays this amber brake
indicator if a brake booster fault is detected. Apply steady pressure and keep the brakes
firm to stop the vehicle when
safety permits. Hydraulic Boost
Compensation will be active (see
Hydraulic
Boost Compensation on page 66).
Emergency Braking
In an emergency, fully press the brake pedal and
maintain
firm pressure, even on low traction surfaces.
The ABS varies the braking pressure to each wheel according to the amount of traction available. This prevents wheels from locking and ensures that you stop as safely as possible.
WARNING: Do not pump the brake pedal. Doing so
interrupts operation of the ABS and can increase
braking distance.
WARNING: Always maintain a safe distance from
the vehicle in front of you and be aware of
hazardous driving conditions. While the ABS can
improve stopping distance, it cannot overcome the
laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of water
prevents direct contact between the tires and the
road).
CAUTION: Automatic Emergency Braking (see
Automatic Emergency Braking on page 123) may
intervene to automatically brake in situations
where a collision is considered imminent.
Automatic Emergency Braking is not designed to
prevent a collision. At best, it can minimize the
impact of a frontal collision by attempting to
reduce your driving speed. Depending on
Automatic Emergency Braking to avoid a collision
can result in serious injury or death.
CAUTION: In emergency situations, if the brakes
are not functioning properly, press and hold the
Park button on the drive stalk to bring the vehicle
to a stop. Do not use this method to stop the
vehicle unless absolutely necessary.
Dynamic Brake Lights (if equipped)
If you are driving over 30 mph (50 km/h) and brake
forcefully
(or if Automatic Emergency Braking engages),
the brake lights
flash quickly to warn other drivers that
Model Y is rapidly slowing down. If Model Y stops
completely, the hazard warning lights
flash. Flashing
continues until you press the accelerator or manually press the hazard lights button to turn them
off (see
Hazard Warning Flashers on page 60).
NOTE: Dynamic brake lights will not flash while Track
Mode is enabled (see
Track Mode on page 74).
NOTE: When towing a trailer (if applicable), the brake
lights on the trailer also operate as described above,
even when the trailer is not equipped with a separate
braking system.
WARNING: When towing a trailer (if applicable),
always increase your following distance. Sudden
braking may result in skidding, jack-knifing, and
loss of control.
Brake Disc Wiping
To ensure brakes remain responsive in cold and wet
weather,
Model Y is equipped with brake disc wiping.
When cold and wet weather is detected, this feature repeatedly applies an imperceptible amount of brake
force to remove water from the surface of the brake discs.

The towing package includes a 2" x 2" (5 cm x 5 cm)
hitch receiver that can support an accessory carrier (for bicycles, skis, snowboards, etc.) or tow a trailer.
Installing and Using a Carrier
When using the tow package to carry accessories, the 2"
x 2" (5 cm x 5 cm) square hitch receiver is designed to
support vertical loads of up to
160 lbs (72 kg). Ball
mounts that are compatible with the square receiver
must be purchased separately.
To install and use an accessory carrier, you must first
attach the ball mount to the hitch receiver (see
Attaching and Removing the Ball Mount on page 83).
Then, follow the instructions provided by your accessory
carrier. Observe all regulations and legal requirements in your state or region that apply to carrying accessories.
The Model Y towing package includes the wiring
necessary for using an accessory carrier equipped with
lights (see
Electrical Connections on page 83). The
package also includes Trailer Mode software compatibility (see
Trailer Mode on page 81).
NOTE: Go to http://www.tesla.com to purchase
accessories for your vehicle. Although third-party products are available, Tesla recommends and supports
only Tesla-approved products (see
Parts and
Accessories on page 198). The accessory products
available for your vehicle may vary based on market
region. Before attempting to install a non Tesla-
approved carrier, review the product information to ensure compatibility.
NOTE: When not in use, the ball mount should be
removed and stored in a dry location to prevent dust and corrosion. Keep the dust cover over the hitch housing to prevent dirt and debris from entering (see
Attaching and Removing the Ball Mount on page 83).
NOTE: Tesla assumes no responsibility for damage or
injuries resulting from installing and using an accessory carrier, for any omissions in the instructions
accompanying an accessory carrier, or for your failure to follow the instructions. Damage caused by using an accessory carrier is not covered by the warranty.
Carrying Accessories
The hitch receiver is designed to support vertical loads
up to
160 lbs (72 kg). When carrying bicycles, skis, or
other items on the
Model Y hitch, always check to
ensure that the maximum weight is not exceeded. When calculating weight, remember to include the weight of
the accessory carrier.
For example, assuming the carrier
weighs 40 lbs (18 kg), the weight threshold is sufficient
for carrying two bicycles weighing approximately 60 lbs
(27 kg) each, or four items weighing approximately 30
lbs (14 kg) each.
NOTE: Consult the product details of your accessory
carrier for more information, such as additional weight or load limits. Damage caused by non Tesla-approved
accessories is not covered by the warranty.CAUTION: Exceeding the maximum weight the
Model Y hitch is designed to support (as
previously described) can cause significant

damage.
CAUTION: Do not attempt to install an accessory
carrier on Model Y that is not equipped with the
tow package. Doing so can cause significant
damage.
Trailer Towing
The maximum trailer weight (including all cargo and
additional equipment), and the trailer tongue weight
depend on the number of occupants in your vehicle and the tires being used. The maximum towing capacity and
trailer tongue weight must never exceed the following:

** You must operate within the speed limitations of your trailer and tires, and only drive at speeds appropriate for
the load you are towing, the weather, road and
traffic
conditions, and your level of towing experience. Always
obey posted speed limits and local regulations regarding
speed.
NOTE: In Canada, towing is limited to 55 mph (89 km/h).
For trailers with a combined loading of more than 1650
lbs (750 kg), Tesla recommends using a separate braking
system with an independent controller (see
Trailer

NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Autosteer, or the
feature may not operate exactly as described.
NOTE: Autosteer is a BETA feature.
Autosteer builds upon Traffic-Aware Cruise Control (see
Traffic-Aware Cruise Control on page 91), intelligently
keeping
Model Y in its driving lane when cruising at a set
speed.
Autosteer also allows you to use the turn signals
to move Model Y into an adjacent lane (see Auto Lane
Change on page 98). Autosteer detects lane markings
and the presence of vehicles and objects to
steer Model
Y.
NOTE: To display more details about the roadway and its
surroundings, such as road markings, stop lights, objects (such as trash cans and poles), etc., touch
Controls >
Autopilot > Full Self-Driving Visualization Preview (if
equipped).
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, affect performance.
WARNING: Autosteer is a hands-on feature. You
must keep your hands on the steering wheel at all
times.
WARNING: Autosteer is intended for use on
controlled-access highways with a fully attentive
driver. When using Autosteer, hold the steering
wheel and be mindful of road conditions and
surrounding traffic. Do not use Autosteer in
construction zones, or in areas where bicyclists or
pedestrians may be present. Never depend on
Autosteer to determine an appropriate driving
path. Always be prepared to take immediate
action. Failure to follow these instructions could
cause damage, serious injury or death.
Operating Autosteer
Before you can operate Autosteer, you must enable it by touching
Controls > Autopilot > Autosteer (Beta).
To indicate that Autosteer is available (but
not actively steering
Model Y), the top
corner of the touchscreen displays a gray
Autosteer icon
next to the driving gear.
To initiate Autosteer, move the drive stalk fully down
twice in quick succession.
To indicate that Autosteer is now actively
steering
Model Y, the touchscreen displays
the Autosteer icon in blue. When Autosteer is able to detect lane markings, it also
displays the driving lane in blue.
Autosteer briefly displays a message on the touchscreen
reminding you to pay attention to the road and be ready
to take over at any time.
The speed at which you can initiate Autosteer can vary depending on various conditions and whether or not a vehicle is detected ahead of you. When no vehicle is
detected ahead of you, you must be driving at least
18 mph (30 km/h), unless certain vehicle and
environmental conditions are met, in which case, you
may be able to initiate it at lower speeds. When a
vehicle is detected ahead of you, you can initiate
Autosteer at any speed, even when stationary, provided
Model Y is at least 5 feet (150 cm) behind the detected
vehicle.
NOTE: Auto High Beam is automatically enabled when
Autosteer is engaged and the maximum cruising speed is
85 mph (140 km/h).
CAUTION: If available in your market region, Model
Y detects lights from an emergency vehicle when
using Autosteer at night on a high speed road, the
driving speed is automatically reduced and the
touchscreen displays a message informing you of
the slowdown. You will also hear a chime and see a
reminder to keep your hands on the steering
wheel. When the light detections pass by or cease
to appear, Autopilot resumes your cruising speed.
Alternatively, you may tap the accelerator to
resume your cruising speed.
WARNING: Never depend on Autopilot features to
determine the presence of emergency vehicles.
Model Y may not detect lights from emergency
vehicles. Keep your eyes on your driving path and
always be prepared to take immediate action.
In situations where Autosteer is temporarily unavailable, the Autosteer icon disappears. For example, your driving speed is not within the speed required for Autosteer to operate. Autosteer may also be unavailable if it is not receiving adequate data from the camera(s).
NOTE: In low light conditions (dusk or dark), Autosteer
aborts or is unavailable if headlights are set to
Off. For
best results, set headlights to
Auto.
If unable to detect lane markings, Autosteer may determine the driving lane based on a vehicle you are
following.
In most cases, Autosteer attempts to center Model Y in
the driving lane. However, there may be situations in which Autosteer may steer
Model Y in a driving path
that is
offset from the center of the lane (for example,
detection of guard rails).
Autosteer
96MODEL Y Owner

In situations where Auto Lane Change is unable to operate at optimal performance, or cannot operate due to inadequate data, the
touchscreen displays a series of
warnings. Therefore, when using Auto Lane Change,
always pay attention to the
touchscreen and be
prepared to manually steer
Model Y.
Adjacent Lane Speed
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Adjacent Lane
Speed, or the feature may not operate exactly as
described.
When moving significantly faster than vehicles in
adjacent lanes,
Model Y automatically reduces the
driving speed. This is especially helpful in heavy
traffic
situations or when vehicles are constantly merging into
different lanes. When Model Y detects other vehicles
driving
significantly slower, the touchscreen highlights
the adjacent lanes with arrows and detected vehicles in gray, and
Model Y reduces the driving speed as
appropriate. To temporarily override this feature, press
the accelerator pedal.
WARNING: Never depend on Autopilot to
determine a safe driving speed; you are
responsible for driving safely and according to
traffic laws in your market region.
Stop Light and Stop Sign Warning
NOTE: Depending on market region, vehicle
configuration, options purchased, and software version,
your vehicle may not be equipped with Stop Light and
Stop Sign Warning, or the feature may not operate
exactly as described.
While Autosteer is in use, Model Y displays a warning on
the
touchscreen and sounds a chime if it detects that
you are likely to run through a red stop light or stop sign. If this happens,
TAKE IMMEDIATE CORRECTIVE
ACTION!
The visual and audible warnings cancel after a few seconds, or when you press the brake pedal, whichever
comes
first.
Stop Light and Stop Sign Warning provides warnings
only. It does not slow down or stop
Model Y at red traffic
lights, stop signs, road markings, etc. If equipped with
Traffic Light and Stop Sign Control, you can enable this
feature to automatically stop Model Y at traffic lights
and stop signs (see Traffic Light and Stop Sign Control
on page 104).
CAUTION: Stop Light and Stop Sign Warning
requires on-board maps to know that a particular
stop light or stop sign exists at a location. In some
cases, map data is inaccurate or outdated and may
not include all stop lights or stop signs. Therefore,
Stop Light and Stop Sign Warning may not detect
all stop lights and stop signs.
WARNING: The Stop Light and Stop Sign Warning
feature does not apply the brakes or decelerate
Model Y and may not detect all stop lights and
stop signs. Stop Light and Stop Sign Warning is
designed for guidance purposes only and is not a
substitute for attentive driving and sound
judgment. Keep your eyes on the road when
driving and never depend on Stop Light and Stop
Sign Warning to warn you of a stop light or stop
sign.
WARNING: Stop Light and Stop Sign Warning is
designed to warn you only when approaching a
visible red stop sign, solid red or later portion of a
yellow traffic light. It may not warn you of
intersections with flashing lights and it does not
warn you of yield signs or temporary stop and
yield signs (such as those used in construction
areas). Additionally, Stop Light and Stop Sign
Warning does not warn you of approaching stop
lights or stop signs when you are pressing the
accelerator pedal or brake pedal (which disables
Autosteer).
Limitations
Autosteer and its associated functions are particularly
unlikely to operate as intended when:

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

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.
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

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

NOTE: The map also has an icon that
allows you to display/hide satellite imagery.
Immediately after initiating Smart Summon in either
mode, hazard lights
briefly flash, mirrors fold, and Model
Y shifts into Drive or Reverse. Model Y then slowly
moves to within
3 feet (1 meter) of you (COME TO ME)
or your chosen destination (GO TO TARGET), navigating obstacles as needed. As
Model Y moves, the
corresponding red arrow on the map also moves to
show the vehicle

About the Security System
If Model Y does not detect an authenticated phone, key
fob, or key card and a locked door or trunk is opened, an alarm sounds. The headlights and turn signals also
flash.

To deactivate the alarm, press any button on the mobile
app or tap your key card or key fob against the card reader located
approximately one third the way up of
the driver
