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 >

WARNING: Obstacle-Aware Acceleration is
designed to reduce the severity of an impact. It is
not designed to avoid a collision.
WARNING: Obstacle-Aware Acceleration may not
limit torque in all situations. Several factors,

2. Self-test of internal ground fault monitoring circuit failed3.
Thermal sensor disconnected
4.
Other hardware component issues
What to do:
An internal issue was detected by the Wall Connector.
1.
Try charging again by disconnecting the Wall Connector from the vehicle and reconnecting.
2.
If the issue persists, turn OFF the circuit breaker for
the Wall Connector, wait 10 seconds, and turn the circuit breaker ON again. Then try reconnecting the Wall Connector to the vehicle.
3.
If the issue persists, check for loose connections.
a.
Make sure there is no power to the Wall
Connector.
b.
Remove the face plate and inspect the wiring
terminals for any loose connections.
c.
Contact an electrician if necessary to make sure all
wires are properly connected and torqued according to the instructions in the Wall Connector Installation Manual.
4.
Once all connections have been checked and made
secure, restore power to the Wall Connector and try charging again by reconnecting to the vehicle.
5.
If the issue persists, the Wall Connector needs service. Schedule a service appointment through
your Mobile App.

Unable to charge - Wall Connector
GFCI tripped
Disconnect and retry or use
different equipment
What this alert means:
Ground fault. Current is leaking through an unsafe path.
Possible Line to ground or Neutral to ground fault.
What to do:
Try again by disconnecting the Wall Connector from the
vehicle and reconnecting. If the problem persists, turn
OFF the circuit breaker servicing the Wall Connector,
wait 10 seconds, turn the circuit breaker ON again, then
try reconnecting the Wall Connector to the vehicle. If the
problem persists, contact Tesla.
