Braking Systems
Model X 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 flashes briefly on
the instrument panel when you firststart Model X. 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.
If the instrument panel displays this
indicator at any time other than
displaying
briefly when you first start
Model X, a brake system fault is
detected or the brake
fluid level is
low. Contact Tesla immediately.
Emergency Braking
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 road).
If Model X is equipped with Autopilot
hardware, Automatic Emergency Braking
automatically applies full braking in situations
where a collision is considered imminent (see
Automatic Emergency Braking on page 89).
Brake Wear Model X brake pads are equipped with wearindicators. 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 stop
the squealing, contact Tesla Service.
Brakes must be periodically inspected visually by removing the tire and wheel. For detailed
specifications and service limits for rotors and
brake pads, see Brakes on page 158.
Warning: Neglecting to replace worn
brake pads results in damage to the
braking system and can create a braking
hazard.

How It WorksThe traction control system constantly
monitors the speed of the front and rear
wheels. If Model X experiences a loss of
traction, the system minimizes wheel spin by
controlling brake pressure and motor power.
By default, the traction control system is
always active. Under normal conditions, it should remain active to ensure maximum
safety.
You can enable slip start to allow the wheels
to spin at a limited speed. Slip start can be
enabled only when Model X is moving
32 km/h or slower. Slip start automatically
disables when the speed exceeds 64 km/h.This indicator flashes on the
instrument panel whenever the
traction control system is actively
controlling brake pressure and motor
power to minimize wheel spin. If the
indicator stays on, a fault is detected with the traction control system.
Contact Tesla Service.Warning: Traction control can not prevent
accidents caused by driving dangerously
or turning too sharply at high speeds.Warning: If the above indicator remains
illuminated without turning off traction
control (single motor vehicles) or
enabling slip start (dual motor vehicles), the traction control system may not be
operating correctly. Contact Tesla Service immediately.
Allowing Wheel Slip (dual motor vehicles)
To allow the wheels to slip at a limited speed,
you can enable Slip Start. Slip Start can be
enabled only when Model X is moving
32 km/h or slower. Slip Start automatically
disables when the speed exceeds 64 km/h.
Under normal conditions, Slip Start should not
be enabled. Enable it only in circumstances where you deliberately want the wheels toslip, such as:

Performance Dual Motor Vehicles
Only
Launch Mode, available on performance dual motor vehicles only, provides optimum
acceleration on surfaces with good traction.
To use Launch Mode, you must set the acceleration level to Insane (or Ludicrous) and
then enable Max Battery Power (see Controls
on page 97).Warning: Use Launch Mode only in
appropriate locations where there is no
cross
traffic or pedestrians present.
Launch Mode is designed for use on
closed circuit driving courses. It is the driver
