Tesla MODEL X Owner's Manual page 101

WARNING: Traffic-Aware Cruise Control cannot
detect all objects and, especially in situations
when you are driving over 50 mph (80 km/h),
may not brake/decelerate when a vehicle or
object is only partially in the driving lane or when
a vehicle you are following moves out of your
driving path and a stationary or slow-moving
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
misjudge the distance from a vehicle ahead.
Driving downhill can increase driving speed,
causing Model X to exceed your set speed (and
potentially the road's speed limit). Never depend
on Traffic-Aware Cruise Control to slow down the
vehicle enough to prevent a collision. Always keep
your eyes on the road when driving and be
prepared to take corrective action as needed.
Depending on Traffic-Aware Cruise Control to slow
the vehicle down enough to prevent a collision can
result in serious injury or death.
HOLD State
When following a vehicle, Traffic-Aware Cruise Control
remains active at low speeds, even when Model X comes
to a full stop. When the vehicle is moving again, Traffic-
Aware Cruise Control resumes operating at the set
speed. However, under the following circumstances,
Traffic-Aware Cruise Control goes into a HOLD state, in
which case, you need to briefly press the accelerator
pedal or pull the Autopilot stalk toward you (see
Canceling and Resuming on page
cruising. When the HOLD status is active, the instrument
panel displays the HOLD icon and a message that
indicates that you need to resume cruise control. The
following circumstances can cause Traffic-Aware Cruise
Control to go into the HOLD state:
• Model X has been at a standstill for 5 minutes.
• Model X detects a pedestrian (the HOLD state may
clear when the pedestrian is no longer detected).
• Model X suddenly loses visibility of the vehicle in
front of you.
• The ultrasonic sensors detect an obstacle in front of
Model X.

Cruising Near or On Freeway Exits
When cruising near an exit on a controlled access road
(such as a highway or freeway) and engaging the turn
signal toward the exit, Traffic-Aware Cruise Control
assumes you are exiting and begins to slow down the
vehicle. If you do not drive onto the exit, Traffic-Aware
Cruise Control resumes cruising at the set speed. In a
region with right hand traffic, this occurs only when you
engage the right turn signal when driving in the right-
most lane within 164 feet (50 meters) of an exit.
Likewise in regions with left hand traffic; when engaging
the left turn signal when driving in the left-most lane
within 164 feet (50 meters) of an exit.
When cruising onto an on-ramp to a controlled access
road (such as a highway or freeway), Traffic-Aware
Cruise Control automatically adjusts the set cruising
speed to the speed limit of the highway, plus any offset
you have specified (see Speed Assist on page
NOTE: The onboard Global Positioning System (GPS)
determines if you are driving in a region with right or left
hand traffic. In situations where GPS data is unavailable
(for example, if there is inadequate signal), engaging the
turn signal near an exit does not cause Traffic-Aware
Cruise Control to slow down Model X.
When enabled while on a highway interchange or off-
ramp, Traffic-Aware Cruise Control may reduce your set
speed in 5 mph (5 km/h) increments – to as slow as
25 mph (40 km/h) – to better match the reported
speeds of other Tesla vehicles that have driven at that
specific location. To override this and continue cruising
at your set speed, tap the accelerator pedal or move the
Autopilot stalk. The new set speed is maintained for the
duration of the interchange or off-ramp (unless you
override it or cancel Traffic-Aware Cruise Control). After
the interchange or off-ramp, the set speed may revert or
change as necessary based on the new location. For
example, if you merged onto a different highway, the set
speed reverts back to the set speed that was in use
before driving on the interchange.
WARNING: In some cases (such as having
insufficient data), Traffic-Aware Cruise Control may
not automatically reduce the set speed on the
highway interchange or off-ramp. Do not rely on
Traffic-Aware Cruise Control to determine an
appropriate driving speed. Tesla recommends
driving at a speed that is safe for road conditions
and within posted speed limits.
Adjust the Following Distance
To adjust the following distance you want to maintain
between Model X and a vehicle traveling ahead of you,
rotate the Autopilot stalk. Choose a setting from 1 (the
closest following distance) to 7 (the longest following
distance). Each setting corresponds to a time-based
distance that represents how long it takes for Model X,
from its current location, to reach the location of the
rear bumper of the vehicle ahead of you.
