Braking SystemsWarning: Properly functioning braking
systems are critical to ensure safety. If you experience a problem with the brake
pedal, brake caliper, or any component of
a Model X braking system, contact Tesla
immediately.
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 beaware 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).
Automatic Emergency Braking automatically
applies full braking in situations where a
collision is considered imminent (see Automatic Emergency Braking on page 109).
Warning: Automatic Emergency Braking
is not designed to prevent a collision. At best, it can minimize the impact of a
frontal collision by attempting to reduce
your driving speed. Depending on Automatic Emergency Braking to avoid a
collision can result in serious injury or death.
Brake Wear
Model X brake pads are equipped with wear indicators. 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
replace the brake pads, 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 184.
Warning:
Neglecting to replace worn
brake pads damages the braking system
and can result in a braking hazard.
Regenerative Braking
Whenever Model X is moving and your foot is
off the accelerator, regenerative braking slows
down Model X 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 X (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.

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 on.
Under normal conditions, it should remain on
to ensure maximum safety.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: If the above indicator remains
illuminated in situations in which you have
not enabled Slip Start (described next), the traction control system may not be
operating correctly. Contact Tesla Service immediately.Warning: Traction control cannot prevent
collisions caused by driving dangerously
or turning too sharply at high speeds.
Allowing Wheel Slip
To allow the wheels to spin at a limited speed,
you can enable Slip Start. Slip Start can be
enabled only when Model X is moving
48 km/h or slower. Slip Start automatically
disables when the speed exceeds 80 km/h.
Under normal conditions, Slip Start should not
be enabled. Enable it only in circumstances where you deliberately want the wheels tospin, such as:

Avoidance Assist feature, Model X
displays an alert. Contact Tesla Service.

7.Displays
Manually control the brightness and the DAY (light background) or NIGHT (dark background)
setting of the touchscreen and instrument panel. When set to AUTO, the brightness changes
automatically between day and night brightness based on ambient lighting conditions. When
Auto-adjust is checked, the displays are further adjusted based on both the surroundings and
by learning your preferences (i.e. it remembers the type of manual adjustments you make).
To disable the touchscreen momentarily for cleaning purposes, touch CLEAN MODE.
You can also put Model X into an energy saving mode so it consumes less energy when not in
use (see Getting Maximum Range on page 76).
Note: The Displays settings can also be accessed from the Controls screen.
8. HomeLink (if equipped)
If the HomeLink feature is available in your region, use it to control RF-enabled garage doors, lights, or security systems (see HomeLink Universal Transceiver on page 148).
9. Driver Assistance
If Model X is equipped with Driver Assistance components, you can control the features that
provide a safer and more convenient driving experience (see About Driver Assistance on page

Service Intervals
Regular maintenance is the key to ensuring
the continued reliability and
efficiency of your
Model X.
Maintain the correct tire pressures, and take
Model X to Tesla at the regularly scheduled
maintenance intervals of every 12 months, or
every 20,000 km, whichever comes
first. It is
also important to perform the daily and
monthly checks described below.
Model X should be serviced by
Tesla-certifiedtechnicians. Damages or failures caused by
maintenance or repairs performed by non-
Tesla
certified technicians are not covered by
the warranty.
Daily Checks

Inspecting and Maintaining TiresRegularly inspect the tread and side walls for
any sign of distortion (bulges), foreign objects,
cuts or wear.Warning: Do not drive Model X if a tire is
damaged, excessively worn, or inflated to
an incorrect pressure. Check tires
regularly for wear, and ensure there are
no cuts, bulges or exposure of the ply/
cord structure.
Tire Wear
Adequate tread depth is important for proper
tire performance. Tires with a tread depth less
than 3 mm are more likely to hydroplane in
wet conditions and should not be used. Tires
with a tread depth less than 4 mm do not
perform well in snow and slush and should not
be used when driving in winter conditions.
Model X is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 3 mm,
the indicators start to appear at the surface of
the tread pattern, producing the
effect of a
continuous band of rubber across the width of
the tire. For optimal performance and safety,
Tesla recommends replacing tires before the
wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Model X tires cannot be rotated, as tires are
asymmetrical and front tires are a
differentsize from rear tires.
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel)
affectvehicle handling and tire life. Even with regular
use, wheels can get out of balance. Therefore,
they should be balanced as required.
If tire wear is uneven (on one side of the tire
only) or becomes abnormally excessive, check
the alignment of wheels.
Note: When replacing only two tires, always
install the new tires on the rear.
Punctured Tires
A puncture eventually causes the tire to lose pressure, which is why it is important to check
tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when
penetrated, provided the object remains in the tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect a tire is damaged, immediately reduce yourspeed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to have Model X
transported to a Tesla Service Center, or to a nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 6 mm) using an optional tire repair kit available from Tesla.
This allows you to slowly drive Model X to Tesla or to a nearby tire repair facility.Warning: Do not drive with a punctured
tire, even if the puncture has not caused the tire to
deflate. A punctured tire candeflate suddenly at any time.
Flat Spots
If Model X is stationary for a long period in
high temperatures, tires can form
flat spots.
When Model X is driven, these flat spots cause
a vibration which gradually disappears as the
tires warm up and regain their original shape.
To minimize
flat spots during storage, inflatetires to the maximum pressure indicated on the tire wall. Then, before driving, release airto adjust tire pressure to the recommended
levels.
Improving Tire Mileage To improve the mileage you get from your
tires, maintain tires at the recommended tire
pressures, observe speed limits and advisory
speeds, and avoid:
