Braking and Stopping
Hydraulic Fade Compensation
Model X is equipped with hydraulic fade compensation.
This assists in monitoring brake system pressure and
ABS activity for instances of reduced brake
performance. If reduced brake performance is detected
(for example, as a result of brake fade, or cold or wet
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 58
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 X 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 X, 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 X 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.
The power meter on the Energy app displays real-time
feedback on the amount of power being used. You can
also display the power meter on either side of the
instrument panel by choosing Energy using the scroll
button on the steering wheel (see
page 52). When energy is being gained by regenerative
braking, the power meter displays a green area that
represents the amount of power that is being fed back
to the Battery.

Steering Wheel on
The amount of power 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 cold or is already fully charged.
When regenerative braking is limited, the power meter
displays a dashed line to indicate the amount of
deceleration power that is not being fed back to the
Battery.
WARNING: In snowy or icy conditions, Model X
may experience loss of traction during
regenerative braking, particularly when in the
Standard setting and/or not using winter tires.
Tesla recommends using the Low setting (see
Set the Regenerative Braking Level on page
in snowy or icy conditions to help maintain vehicle
stability.
To Set the Regenerative Braking Level
NOTE: The regenerative braking setting is not available
on all vehicles.
You can use the touchscreen to change the level of
regenerative braking:
1. Touch Controls > Pedals & Steering > Regenerative
Braking.
2. Choose from two levels:
◦ Standard: Provides the maximum amount of
regenerative braking. When you release the
accelerator, Model X slows down, reducing the
need to use the brakes.
◦ Low: Limits regenerative braking. When you
release the accelerator, Model X takes longer to
slow down and coasts further than if set to
"Standard".
