HOLD State
When following a vehicle, Trac-Aware Cruise Control
remains active at low speeds, even when Model X comes
to a full stop. When the vehicle is moving again, Trac-
Aware Cruise Control resumes operating at the set
speed. However, under the following circumstances,
Trac-Aware Cruise Control goes into a HOLD state, in
which case, you need to briefly press the accelerator
pedal to resume 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 Trac-
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.
• An obstacle is detected in front of Model X.
Cruising Near or On Exits
When cruising near an exit on a controlled-access
highway and engaging the turn signal toward the o-
ramp, Trac-Aware Cruise Control assumes you are
exiting and begins to slow down Model X. If you do not
drive onto the o-ramp, Trac-Aware Cruise Control
resumes cruising at the set speed. In a region with right
hand trac, 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 trac; 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
highway, Trac-Aware Cruise Control automatically
adjusts the set cruising speed to the speed limit of the
highway, plus any
oset you have specified.
NOTE: The on-board Global Positioning System (GPS)
determines if you are driving in a region with right or left
hand
trac. In situations where GPS data is unavailable
(for example, if there is inadequate signal), engaging the
turn signal near an exit does not cause Trac-Aware
Cruise Control to slow down Model X.
When enabled while on a highway interchange or o-
ramp, Trac-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. The new set
speed is maintained for the duration of the interchange
or
o-ramp (unless you override it or cancel Trac-
Aware Cruise Control). After the interchange or o-
ramp, the set speed may revert or change as necessary
based on the new location. For example, if you merged
onto a
dierent highway, the set cruising speed reverts
back to what it was before driving on the interchange.
WARNING: In some cases (such as having
insucient data), Trac-Aware Cruise Control may
not automatically reduce the set speed on the
highway interchange or o-ramp. Do not rely on
Trac-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,
touch
Controls > Autopilot > Cruise Follow 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. Your setting is
retained until you manually change it.
The closest following distance is 2.
WARNING:
It is the driver's responsibility to
determine and maintain a safe following distance
at all times. Do not rely on Trac-Aware Cruise
Control to maintain an accurate or appropriate
following distance.
WARNING:
Never depend on Trac-Aware Cruise
Control to adequately slow down Model X to avoid
a collision. Always watch the road in front of you
and stay prepared to take immediate corrective
action.
Overtake Acceleration
When following a vehicle with Trac-Aware Cruise
Control active, 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, you can quickly accelerate up to your set speed
without having to press the accelerator pedal. The turn
signal causes acceleration only when all of the following
conditions are met:
•
Trac-Aware Cruise Control is operating and detects
a vehicle in front of you.
• No obstacles or vehicles are detected in the target
lane.
•
Model X is traveling below the set speed, but over
45 mph (72 km/h).
Overtake Acceleration is intended as an aid when
passing a vehicle ahead of you. When the turn signal is
engaged,
Trac-Aware Cruise Control continues to
maintain distance from the vehicle ahead, but allows you
to drive slightly closer than your selected distance.
