How It WorksYour Model X includes the following Driver Assistance components that actively monitor the
surrounding roadway:
1. A camera is mounted above the rear license plate.
2. Ultrasonic sensors are located in the front and rear bumpers.
3. A camera is mounted in each door pillar.
4. Three cameras are mounted to the windshield above the rear view mirror.
5. A camera is mounted to each front fender.
6. Radar is mounted behind the front bumper on the right side of the vehicle.
Model X is also equipped with high precision electronically-assisted braking and steering systems.

Note: Traffic-Aware Cruise Control is a BETA
feature.
If you have purchased the optional Enhanced Autopilot or Full Self-Driving Capabilitypackage, the forward looking cameras and theradar sensor are designed to determine when
there is a vehicle in front of you in the same
lane. If the area in front of Model X is clear,
Traffic-Aware Cruise Control maintains a set
driving speed. When a vehicle is detected,
Traffic-Aware Cruise Control is designed to
slow down Model X as needed to maintain a
selected time-based distance from the vehicle in front, up to the set speed.
Traffic-AwareCruise Control does not eliminate the need towatch the road in front of you and to manuallyapply the brakes when needed.
Traffic-Aware Cruise Control is primarily
intended for driving on dry, straight roads,
such as highways and freeways. It should not be used on city streets.
Warning: Traffic-Aware Cruise Control is
designed for your driving comfort and
convenience and is not a collision warning or avoidance system. It is your
responsibility to stay alert, drive safely,
and be in control of the vehicle at all
times. Never depend on
Traffic-AwareCruise Control to adequately slow down
Model X. Always watch the road in front
of you and be prepared to take corrective
action at all times. Failure to do so can
result in serious injury or death.
Warning: Although Traffic-Aware Cruise
Control is capable of detecting
pedestrians and cyclists, never depend on
Traffic-Aware Cruise Control to
adequately slow Model X down for them.
Always watch the road in front of you and
be prepared to take corrective action at
all times. Failure to do so can result in
serious injury or death.
Warning: Do not use Traffic-Aware Cruise
Control on city streets or on roads where
traffic conditions are constantly changing.
Warning: Do not use Traffic-Aware Cruise
Control on winding roads with sharp
curves, on icy or slippery road surfaces, or
when weather conditions (such as heavy
rain, snow, fog, etc.) make it inappropriate
to drive at a consistent speed.
Traffic-
Aware Cruise Control does not adapt
driving speed based on road and driving
conditions.
Operating Traffic-Aware Cruise
Control
To use
Traffic-Aware Cruise Control, you must
be driving at least 30 km/h, unless a vehicle is
detected ahead of you. If a vehicle is detected ahead of you, you can use
Traffic-AwareCruise Control at any speed, even when
stationary, provided you are at least 150 cm
away from the vehicle.
The minimum set speed is 30 km/h. The
maximum set speed is 150 km/h. It is the
driver
Page 93 of 213
The gray speedometer icon
on the instrument panel
turns blue and displays the
set speed to indicate that
Traffic-Aware Cruise Control
is active.
Note: The minimum set speed is 30 km/h. The
maximum set speed is 150 km/h. It is the
driver

brake/decelerate for stationary vehicles
or objects, especially in situations when
you are driving over 80 km/h and in situations where a vehicle you are
following moves out of your driving path and a stationary vehicle or object is in
front of you. Always pay attention to the
road ahead and stay prepared to take
immediate corrective action. Depending
on
Traffic-Aware Cruise Control to avoid
a collision can result in serious injury or death. In addition,
Traffic-Aware Cruise
Control may react to vehicles or objects
that either do not exist or are not in the
lane of travel, causing Model X to slow
down unnecessarily or inappropriately.
Warning: Traffic-Aware Cruise Control
may be unable to provide adequate
speed control because of limited braking capability and hills. It can also misjudgethe distance from a vehicle ahead. Driving
downhill can increase driving speed, causing Model X to exceed your set
speed (and potentially the road
Page 95 of 213

Note: Your set speed will use your current
driving speed if you move the cruise control lever up or down.
Note: If Speed Assist is unable to determine a
speed limit, your set speed does not change
when you pull the cruise control lever toward
you.Warning: Do not rely on Speed Assist orTraffic-Aware Cruise Control to
determine an accurate or appropriate
cruising speed. Always cruise at a safe
speed based on road conditions and
applicable speed limits.
Changing the Set Speed
To change the set speed while using
Traffic-
Aware Cruise Control, move the cruise control
lever up (increase) or down (decrease) until
your desired set speed is displayed.
To increase/decrease speed by 1 km/h, move
the lever up or down to the first position and
release. To increase/decrease speed to the closest 5 km/h increment, move the lever up/
down to the second position and release. For
example, if you are traveling at 83 km/h and you move the lever up to the second position
and release, the speed increases to 85 km/h.
You can also increase/decrease speed by
holding the lever in the full up/down position
and releasing when the desired speed displays
below the cruise control icon.
To cruise at the speed limit that is currently
being determined by Speed Assist (including any
offsets that you have set), pull the cruise
control lever toward you. See Speed Assist on
page 112.
Note: It may take a few seconds for Model X
to reach the new cruising speed, assuming
Model X does not detect a vehicle ahead
driving slower than your set speed.
Overtake Acceleration
When following a vehicle with
Traffic-AwareCruise Control active, briefly engaging the
turn signal (to indicate a move into the
passing lane) accelerates Model X towards the
vehicle ahead. By momentarily holding the
turn signal lever up or down, you can quickly
accelerate up to your set speed without
having to press the accelerator pedal. The turn
signal accelerates only when the following conditions are met:
Page 96 of 213

never depend on Overtake Acceleration
to increase your driving speed.Warning: Overtake Acceleration increases
your driving speed whenever the
appropriate turn signal is engaged, and
accelerates Model X closer to the vehicle
ahead. Although
Traffic-Aware Cruise
Control continues to maintain distance
from the vehicle ahead, it is important to
be aware that your selected following
distance is reduced when Overtake
Acceleration is active, particularly in cases
where it may not be your intention to
overtake the vehicle you are following.
Canceling and Resuming
To manually cancel
Traffic-Aware Cruise
Control, briefly push the cruise control lever
away from you or press the brake pedal. The
speedometer icon on the instrument panel
turns gray to indicate that
Traffic-AwareCruise Control is not actively controlling your
speed.
To resume cruising at the previously set speed,briefly pull the cruise control lever toward you.
To resume cruising at the current driving
speed, move the cruise control lever up or
down, then release
Note: When Traffic-Aware Cruise Control
cancels, Model X does not coast. Instead, regenerative braking slows down Model X in
the same way as when you move your foot
offthe accelerator when driving without Traffic-
Aware Cruise Control (see Regenerative
Braking on page 66).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:
