Braking and Stopping – Braking Systems
WARNING: 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
If the touchscreen displays 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 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
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
Automatic Emergency Braking is designed to
automatically brake in situations where a collision is
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
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
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—
brake as you normally would.
CAUTION: If brakes are not functioning properly,
stop the vehicle as soon as safety permits and
contact Tesla Service. If necessary, use the Park button
to stop the vehicle in case of emergency
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.
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
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.
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:
• CREEP: When close to, or at, a complete stop, the
motor continues to apply torque, moving Model Y
slowly forward (in Drive) or backwards (in Reverse),
similar to a conventional vehicle with an automatic
transmission. In some situations, such as on a steep
hill or driveway, you may need to press the
accelerator pedal to continue moving or to prevent
Model Y from moving in the opposite direction.
WARNING: Never rely on CREEP to apply
enough torque to prevent your vehicle from
rolling down a hill. Always press the brake pedal
to remain stopped or the accelerator pedal to
proceed up the hill. Failure to do so can result in
property damage and/or a collision.
• HOLD: Maximizes range and reduces brake wear by
continuing to provide regenerative braking at speeds
lower than with the Creep and Roll settings. When
Model Y stops, the brakes are automatically applied
without you having to put your foot on the brake
pedal. Whether stopped on a flat surface or a hill,
Vehicle Hold keeps the brake applied, provided your
foot remains off the accelerator and brake pedals.
WARNING: Never rely on HOLD to adequately
decelerate or fully stop your vehicle. Many
factors can contribute to a longer stopping
distance, including downward slopes, and
reduced or limited regenerative braking.
Always be prepared to use the brake pedal
to adequately decelerate or stop.
• ROLL: When close to, or at, a complete stop, Model Y
becomes free rolling like a vehicle in Neutral.
Therefore, if stopped on a slope, Model Y will roll
downward. The brake does not engage, and the
motor does not apply torque (until the accelerator
pedal is pressed).
NOTE: If you choose CREEP or ROLL, you can still
use Vehicle Hold to apply the brakes. However, you
will need to briefly press the brake pedal when the
vehicle is stopped.
WARNING: Press the brake pedal if Model Y moves
when unsafe to do so. It is your responsibility to
stay alert and be in control of the vehicle at all
times. Failure to do so can result in serious
damage, injury, or death.
WARNING: Do not rely on regenerative braking
and your chosen Stopping Mode to keep you and
your vehicle safe. Various factors such as driving
with a heavy vehicle load, on a steep hill, or on wet
or icy roads affect deceleration rate and the
distance at which Model Y will come to a stop.
Drive attentively and always stay prepared to use
the brake pedal to stop as appropriate based on
traffic and road conditions.
WARNING: Forward Collision Warning and
Automatic Emergency Braking do not operate
when driving at very low speeds. Do not rely
on these features to warn you, or to prevent
or reduce the impact of a collision.
NOTE: Your chosen setting is retained in your Driver
Profile until you manually change it.
To engage the parking brake, touch
Controls > Safety & Security > Parking Brake
and follow the onscreen instructions.
You can also engage the parking brake by
pressing and holding the button on the end of the
drive stalk while in Park.
NOTE: The parking brake operates on the rear wheels
only, and is independent of the pedal-operated brake
WARNING: In snowy or icy conditions the rear
wheels may not have sufficient traction to prevent
Model Y from sliding down a slope, particularly if
not using winter tires. Avoid parking on hills in
snowy or icy conditions. You are always
responsible for parking safely.
WARNING: Your Model Y may display an alert if
the road is too steep to safely park on, or if the
parking brakes are not properly engaged. These
alerts are for guidance purposes only and are not
a substitute for the driver’s judgment of safe
parking conditions, including specific road or
weather conditions. Do not depend on these
alerts to determine whether or not it is safe to
park at any location. You are always responsible
for parking safely.
When you manually apply the parking
brake using the touchscreen (Controls >
Safety & Security > Parking Brake), or
by pressing and holding the button on
the end of the drive stalk when in Park,
the red parking brake indicator (P) PARK
lights up on the touchscreen.
If the parking brake experiences an
electrical issue, the amber parking brake
indicator (P) lights up and a fault message
displays at the top of the touchscreen.
CAUTION: In the unlikely event that Model Y loses
electrical power, you cannot access the
touchscreen and are therefore unable to release
the parking brake without first jump starting
Model Y brake pads are equipped with wear indicators.
A wear indicator is a thin metal strip attached to the
brake pad that squeals as it rubs against the rotor when
the pad wears down. This squealing sound indicates
that the brake pads have reached the end of their
service life and require replacement. To replace the
brake pads, contact Tesla Service.
Brakes must be periodically inspected visually by
removing the tire and wheel. Additionally, Tesla
recommends cleaning and lubricating the brake calipers
every year or 12,500 miles (20,000 km) if in an area
where roads are salted during winter months.
WARNING: Neglecting to replace worn brake
pads damages the braking system and can result
in a braking hazard.
