conditions), you may hear a sound, feel the brake pedal
pull away from your foot, and notice a strong increase in
braking. Brake as you normally would and continue to
press the brake pedal without releasing or pumping the
brakes.
CAUTION: If brakes are not functioning properly,
stop the vehicle when safety permits and contact
Tesla Service. See Park on page 55
on using 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.
Brake disc wiping and hydraulic fade
compensation is not a substitute for adequately
applying the brakes.
Hydraulic Boost Compensation
Model Y is equipped with a brake booster that activates
the brakes when the brake pedal is pressed. Hydraulic
boost compensation provides mechanical assistance if
the brake booster fails. If a brake booster failure is
detected, the brake pedal feels stiffer to press and you
may hear a sound when you press the brake pedal. To
stop Model Y, apply steady force to the brake pedal
without releasing or pumping. Drive cautiously and
maintain a safe distance from other road users—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 the vehicle
and feeds any surplus power 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.
Vehicle deceleration due to regenerative braking may
vary depending on the current state of the Battery. For
example, regenerative braking may be limited if the
Battery is cold or is already fully charged.
The power meter (a thin horizontal line centered at the
top of the touchscreen's car status area) displays real-
time power usage:
1. The left side of the power meter represents power
generated from regenerative braking, or power that is
used to slow down the vehicle. Power being fed back
to the Battery displays in green whereas power used
by the regular braking system displays in gray.

Braking and Stopping
2. The right side of the power meter shows power that
is used to accelerate the vehicle. During acceleration,
the power meter fills to the right with gray to
represent the amount of power being used.
NOTE: To ensure visibility when the display is dark,
power represented by the gray color displays as white.
NOTE: Installing winter tires with aggressive compound
for information
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 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.
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 > Pedals &
Steering > 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.
• 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.
See
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.
