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 travel increases and you may hear a sound when you
press the brake pedal. Drive cautiously and maintain a safe
distance from other road users—brake pedal responsiveness
and braking performance may be degraded. Braking
distances may increase.
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. Regenerative
braking may also occur, depending on Battery availability,
when you press the brake pedal.
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 line in the touchscreen's car status
area) displays real-time power usage:
1.
Represents power being output by the Battery, such as
that used to accelerate the vehicle. When you press the
accelerator pedal, the top half of the power meter fills
with black (or white if the display is dark).
2. Represents power generated from regenerative braking,
or power that is captured from slowing down the vehicle.
Power being fed back to the Battery displays in green.
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
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. Touch
Service > Wheel & Tire > Tires to select winter tires and
quicken this process.
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.
