TESLA MODEL X 2018   Repair Manual

Controlling Lights
Touch Controls on the bottom corner of the touchscreen to control most of the lights.
In addition to the lights that you can control from the touchscreen, Model X has convenience
lights that turn on and
off automatically based on what you are doing. For example, you will
notice interior lights, marker lights, tail lights, door handle lights, and puddle lights that turn on
when you unlock Model X, when you open a door, and when you shift into Park. They turn
offautomatically after a minute or two or when you shift into a driving gear or lock Model X.

2. If you touch DOME, a popup appears that allow you to control cabin lights. If cabin lights are
set to ON, all interior cabin lights, including the light in the rear trunk, turn on when you
unlock Model X, open a door upon exiting, or shift into P (Park). They turn
off after 60
seconds, when you lock Model X, or when you shift into a driving gear. If set to AUTO, cabin
lights turn on only when little or no light is detected.
You can also turn on an individual dome light by touching its lens. If you manually turn a domelight on, it turns
off when Model X powers off. If Model X was already powered off when you
manually turned the light on, it turns off after 60 minutes.
3. If you turn on AMBIENT lights, the lights on the door arm rests turn on whenever the
headlights are on.
4. Touch to control front passenger side map light.
5. Touch to turn the fog lights on or
off. Fog lights operate only when low beam headlights are
on. When headlights are turned off, fog lights also turn off.
The Rear Fog indicator displays on the instrument panel whenever rear fog
lights are on.The Front Fog indicator displays on the instrument panel whenever the
optional front fog lights are on.
6. If Model X is equipped with a coil suspension system, you can adjust the angle of the
headlights to accommodate the load you are carrying. You may need to lower the angle of theheadlights to avoid blinding oncoming drivers in situations when you are carrying a
significantamount of weight in the rear trunk. After touching LEVEL, drag the slider to the desired
position:
0Headlights are not lowered. No change is needed when all front and rear seats are
occupied and only the front trunk is laden.1Headlights are lowered one level. Suitable when the front and rear seats are occupied and the rear trunk is laden.2Headlights are lowered two levels. Suitable when carrying heavy loads.
Note: Headlight adjustments are not available if Model X is equipped with Smart Air
Suspension because Model X levels automatically.

7.Exterior lights (headlights, tail lights, side marker lights, parking lights, and license plate
lights) are set to AUTO each time you start Model X.
AUTOExterior lights automatically turn on when driving in low lighting conditions.
If you change to a different setting, lights always revert to this AUTO setting
on your next drive.
Touch one of these options to temporarily change the exterior light setting:
OFFExterior lights turn off until you manually turn them back on or until the next
time you drive Model X. If daytime running lights are required in your region,
the exterior lights used for this purpose do not turn
off.Only the side marker lights, parking lights, tail lights and license plate lights
turn on.Exterior lights turn on.
Note: Model X has a series of lights along the lower rim of the headlights, also referred to as
"signature" lights. These lights automatically turn on whenever Model X is powered on and a driving gear is engaged.
Warning: Always ensure that your headlamps are switched to AUTO or ON, as
appropriate, during all low visibility conditions. Failure to do so may result in a collision.
8. If you turn on AUTO HIGH BEAM, high beam headlights turn on and off automatically based
on whether or not light is detected in front of Model X (see High Beam Headlights on page

The turn signals stop operating when canceledby the steering wheel, or when you return the
lever to the central position.
The corresponding turn signal
indicator lights up on the instrument
panel when a turn signal is
operating. You also hear a clicking
sound.Warning: If you have purchased the
optional Enhanced Autopilot or Full Self-
Driving Capability packages and
Traffic-
Aware Cruise Control is active, engaging
a turn signal can cause Model X to
accelerate when using
Traffic-AwareCruise Control in specific situations (see
Overtake Acceleration on page 94).
Warning: If you have purchased the
optional Enhanced Autopilot or Full Self-
Driving Capability packages and
Autosteer is active, engaging a turn signal
may cause Model X to change lanes (see
Auto Lane Change on page 100).

fivepositions:

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.

Warning: In snowy or icy conditions
Model X may experience traction loss
during regenerative braking, particularly
when in the Standard setting and/or not
using winter tires. Tesla recommends
using the Low setting (see To Set the
Regenerative Braking Level on page 67)
in snowy or icy conditions to help maintain vehicle stability.
The Energy app displays real-time feedbackon the amount of energy being gained by
regenerative braking. 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 Steering
Wheel on page 47).
The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. For example, regenerative braking may be limited if theBattery is already fully charged or if the
ambient temperature is too cold.
Note: If regenerative braking is limited, a
dashed yellow line displays on the power
meter.
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:

cannot access the touchscreen and are
therefore unable to release the parking
brake. Contact Tesla.

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:
