Braking SystemsWARNING: Properly functioning braking systems
are critical to ensure safety. If you experience a
problem with the brake pedal, brake caliper, 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 yellow
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.
If the touchscreen displays this yellow
brake indicator at any time, a brake booster fault is detected. Apply steady
pressure and keep the brakes
firm to
bring the vehicle to a stop when safe to do so. Hydraulic Boost Compensation will be active (see
Hydraulic Boost
Compensation on page 61).
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).
Automatic Emergency Braking is designed to automatically brake in situations where a collision is
considered imminent (see
Automatic Emergency
Braking on page 115).
WARNING: 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.
Brake Disc Wiping
To ensure your 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 clear away water from the surface of the brake discs.
Hydraulic Fade Compensation
Your vehicle is also equipped with hydraulic fade
compensation. This feature assists in monitoring brake
system pressure and ABS activity for instances of lower
brake performance. If lower brake performance is
detected (for example, as a result of brake fade, or cold
or wet conditions), you may feel the brake pedal pull away from your foot, detect some noise, and notice a strong increase in vehicle braking. Continue to press the
brake pedal without releasing or "pumping" them

WARNING: Always maintain a safe driving
distance from the vehicle in front of you and
exercise caution when driving conditions are
hazardous. Do not rely on brake disc wiping or
hydraulic fade compensation to act as a
substitute for adequately applying the brakes.
Hydraulic Boost Compensation
Model Y is equipped with a brake booster that provides
a mechanical advantage that
effectively activates the
brakes when the brake pedal is pressed. Hydraulic boost
compensation provides mechanical assist in the event of a brake booster failure. If a brake booster failure is detected, the brake pedal may feel harder to press and you may hear some noise when you press the brake
pedal. To stop the vehicle, apply adequate steady force on the brake pedal without releasing or "pumping" them. Exercise caution while driving and maintain a safe
distance as brake pedal responsiveness and braking performance may be degraded.
Regenerative Braking
Whenever Model Y is moving and your foot is off the
accelerator, regenerative braking slows down
Model Y
and feeds any surplus energy back to the Battery.
By anticipating your stops and reducing or removing
pressure from the accelerator pedal to slow down, you
can take advantage of regenerative braking to increase
driving range. Of course, this is no substitute for regular
braking when needed for safety.
NOTE: If regenerative braking is aggressively slowing
Model Y (such as when your foot is completely off the
accelerator pedal at highway speeds), the brake lights turn on to alert others that you are slowing down.
NOTE: Installing winter tires with aggressive compound
and tread design may result in temporarily-reduced regenerative braking power. However, your vehicle is
designed to continuously recalibrate itself, and after changing tires it will increasingly restore regenerative braking power after some moderate-torque straight-line accelerations. For most drivers this occurs after a short period of normal driving, but drivers who normally
accelerate lightly may need to use slightly harder accelerations while the recalibration is in progress.
WARNING: In snowy or icy conditions Model Y
may experience traction loss during regenerative
braking.
The amount of energy fed back to the Battery using regenerative braking can depend on the current state of the Battery. For example, regenerative braking may be
limited if the Battery is already fully charged or if the
ambient temperature is too cold.
NOTE: If regenerative braking is limited, a dashed line
displays on the energy bar (see
Driving Status on page
57).
Stopping Mode
Regenerative braking decelerates Model Y whenever you
release the accelerator pedal when driving. You can
choose what you want
Model Y to do once the driving
speed has been reduced to a very low speed (almost at
a stop) and both the accelerator pedal and brake pedal
are released. While in Park, touch
Controls > Driving >
Stopping Mode and choose from these options:

When Model Y is stopped, Vehicle Hold can continue to
apply the brakes even after you remove your foot from
the brake pedal. When driving on a hill or on a
flat
surface, brake as you normally would. After coming to a
complete stop, simply press the brake pedal again (until
the
touchscreen displays the Vehicle Hold indicator
light) to enable Vehicle Hold. You can then release the
brake pedal and remain stopped, even on a hill.
This indicator displays on the
touchscreen whenever Vehicle Hold is
actively braking
Model Y.
To disengage Vehicle Hold, press the accelerator pedal or press and release the brake pedal.
NOTE: Shifting into Neutral also disengages Vehicle
Hold.
NOTE: After actively braking Model Y for approximately
ten minutes,
Model Y shifts into Park and Vehicle Hold
cancels.
Model Y also shifts into Park if it detects that
the driver has left the vehicle.
NOTE: When Stopping Mode is set to Hold (see
Stopping Mode on page 61), Vehicle Hold engages
automatically whenever
Model Y stops while in a driving
gear. There is no need to press the brake to engage it.

WARNING: Forward Collision Warning may
provide a warning in situations where the
likelihood of collision may not exist. Stay alert and
always pay attention to the area in front of Model
Y so you can anticipate whether any action is
required.
WARNING: Forward Collision Warning operates
only when driving between approximately 7 mph
(10 km/h) and 90 mph (150 km/h).
WARNING: Forward Collision Warning does not
provide a warning when the driver is already
applying the brake.
Automatic Emergency Braking
The forward looking camera(s) and the radar sensor are designed to determine the distance from a detected object traveling in front of
Model Y. When a frontal
collision is considered unavoidable, Automatic Emergency Braking is designed to apply the brakes to
reduce the severity of the impact.
When Automatic Emergency Braking applies the brakes,
the
touchscreen displays a visual warning and sounds a
chime. You may also notice abrupt downward movement of the brake pedal. The brake lights turn on to alert other road users that you are slowing down.
If driving 35 mph (56 km/h) or faster, the brakes are
released after Automatic Emergency Braking has reduced your driving speed by
30 mph (50 km/h). For
example, if Automatic Emergency Braking applies braking when driving
56 mph (90 km/h), it releases the
brakes when your speed has been reduced to
26 mph
(40 km/h).
Automatic Emergency Braking operates only when driving between approximately
7 mph (10 km/h) and 90
mph (150 km/h).
Automatic Emergency Braking does not apply the
brakes, or stops applying the brakes, when:

Cleaning the Exterior
To prevent damage to the paint, immediately remove
corrosive substances (bird droppings, tree resin, dead insects, tar spots, road salt, industrial fallout, etc.). Do not wait until
Model Y is due for a complete wash. If
necessary, use denatured alcohol to remove tar spots and stubborn grease stains, then immediately wash the area with water and a mild, non-detergent soap to remove the alcohol.
Keep the exterior cameras free of dirt, condensation, or obstructions. Occasionally remove any buildup of dirt by
wiping the components with a soft cloth dampened with warm water. These substances can cause autopilot and safety features to stop working (see
Cleaning Cameras
and Sensors on page 82).
Follow these steps when washing the exterior of Model
Y:
1.
Rinse Thoroughly
Before washing, flush grime and grit from the vehicle
using a hose. Flush away accumulations of mud in areas where debris easily collects (such as wheel wells and panel seams). If salt has been used on the highways (such as during winter months), thoroughly
rinse all traces of road salt from the underside of the
vehicle, wheel wells, and brakes.
2.
Hand Wash
Hand wash Model Y using a clean soft cloth and cold
or lukewarm water containing a mild, high-quality car
shampoo.
CAUTION: Some cleaners and car shampoos
contain chemicals that can cause damage or
discoloration, especially to plastic trim pieces,
lamps, or camera lenses. For example, some car
cleaning formulas contain hydroxide or other
highly alkaline or caustic ingredients that can
damage exterior components. Damage or
discoloration resulting from cleaning products
is not covered by the warranty.
3.
Rinse with Clean Water
After washing, rinse with clean water to prevent soap from drying on the surfaces.
4.
Dry Thoroughly and Clean Exterior Glass
After washing and rinsing, dry thoroughly with a chamois. If necessary, dry the brakes by going on a
short drive and applying the brakes multiple times.
Clean windows and mirrors using an automotive glass cleaner. Do not scrape, or use any abrasive cleaning
fluid on glass or mirrored surfaces.
Cautions for Exterior CleaningCAUTION: Do not wash in direct sunlight.CAUTION: Do not use windshield treatment fluids.

Doing so can interfere with wiper friction and
cause a chattering sound.
CAUTION: Do not use hot water, detergents, or
highly alkaline or caustic cleaning products,
especially those containing hydroxide.
CAUTION: If using a pressure washer, maintain a
distance of at least 12" (30 cm) between the
nozzle and the surface of Model Y. Avoid aiming
the water jet directly on the camera(s) or parking
sensors (if equipped). Also do not clean a sensor
or camera lens with a sharp or abrasive object that
can scratch or damage its surface. Keep the nozzle
moving and do not concentrate the water jet on
any one area.
CAUTION: Do not aim water hoses directly at
windows, door, or hood seals or at electronic
modules or exposed cabling.
CAUTION: To avoid corrosive damage that may
not be covered by the warranty, rinse away any
road salt from the underside of the vehicle, wheel
wells, and brakes. After cleaning the vehicle, dry
the brakes by going on a short drive and applying
the brakes multiple times.
CAUTION: Avoid using tight-napped or rough
cloths, such as washing mitts. A high-quality
microfiber cleaning cloth is recommended.
CAUTION: If washing in an automatic car wash, use
touchless car washes only. These car washes have
no parts (brushes, etc.) that touch the surfaces of
Model Y. Some touchless car washes use caustic
solutions that, over time, can cause discoloration
of decorative exterior trim. Avoid exposure to
soaps and chemicals above pH 13. If unsure, check
the product label or ask the staff at the car wash.
Damage caused by improper washing is not
covered by the warranty.
CAUTION: Ensure the wipers are off before
washing Model Y to avoid the risk of damaging the
wipers.
CAUTION: Do not use chemical based wheel
cleaners or pre-wash products. These can damage
the finish on the wheels.
WARNING: Never spray liquid at a high velocity
(for example, if using a pressure washer) towards
the charge port while Model Y is charging. Failure
to follow these instructions can result in serious
injury or damage to the vehicle, charging
equipment, or property.

Open the hood.
2.
Pull the maintenance panel upward to release the clips that hold it in place.
3.
If checking the Battery coolant, remove the cabin intake trim panel by pulling it upwards to release the clips that hold it in place.
CAUTION: The maintenance panel protects the
front trunk from water. When re-attaching, make
sure it is fully seated.
Checking Battery Coolant
Your Battery coolant should not need to be replaced for the life of your vehicle under most circumstances. However, if the quantity of
fluid in the cooling system
drops below the recommended level, the
touchscreen
displays a warning message. Stop driving Model Y as
soon as safety permits and contact Tesla.
Fluid Level Check
DO NOT REMOVE THE FILLER CAP AND DO NOT ADD
FLUID. Doing so can result in damage not covered by
the warranty.
Do Not Top Up Battery Coolant
WARNING: Battery coolant can be hazardous and
can irritate eyes and skin. Under no circumstances
should you remove the filler cap and/or add
coolant. If the touchscreen warns you that the
fluid level is low, contact Tesla immediately.
To maximize the performance and life of the Battery, the cooling system uses a
specific mixture of G-48
ethylene-glycol coolant (HOAT). Contact Tesla for more
specific information about the coolant.
Checking Brake FluidWARNING: Contact Tesla immediately if you
notice increased movement of the brake pedal or
a significant loss of brake fluid. Driving under
these conditions can result in extended stopping
distances or complete brake failure.
A red brake indicator on the
touchscreen alerts you if the quantity of
fluid in the brake reservoir drops below
the recommended level. If it displays while driving, stop as soon as safety permits by gently applying the brakes.
Do not continue driving. Contact Tesla
immediately.
Topping Up the Brake Fluid
Do not top up your brake fluid. The following
instructions are provided for information purposes and future reference only:
1.
Clean the filler cap before removing it to prevent dirt
from entering the reservoir.
2.
Unscrew the cap and remove it.
3.
Top up the reservoir to the MAX mark using the
appropriate brake
fluid.
4.
Replace the filler cap, ensuring it is fully secured.
WARNING: Only use new fluid from a sealed air-
tight container. Never use previously used fluid or
fluid from a previously opened container
