Tesla Model 3 - Adjust the Following Distance

WARNING: Trac-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 3 to exceed your set speed
(and potentially the road's speed limit). Never
depend on Trac-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 Trac-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, Trac-Aware Cruise Control
remains active at low speeds, even when
Model 3 comes
to a full stop. When the vehicle is moving again, Trac-
Aware Cruise Control resumes operating at the set
speed. However, under the following circumstances,
Trac-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
touchscreen displays the HOLD icon and a
message that indicates that you need to resume cruise
control. The following circumstances can cause Trac-
Aware Cruise Control to go into the HOLD state:
•
Model 3 has been at a standstill for 5 minutes.
•
Model 3 detects a pedestrian (the HOLD state may
clear when the pedestrian is no longer detected).
•
Model 3 suddenly loses visibility of the vehicle in
front of you.
•
The ultrasonic sensors detect an obstacle in front of
Model 3.
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,
Trac-Aware Cruise Control
assumes you are exiting and begins to slow down the
vehicle. If you do not drive onto the exit, Trac-Aware
Cruise Control resumes cruising at the set speed. In a
region with right hand
trac, 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 trac; 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), Trac-Aware
Cruise Control automatically adjusts the set cruising
speed to the speed limit of the highway, plus any oset
you have specified (see Speed Assist on page 116).
NOTE:
The onboard Global Positioning System (GPS)
determines if you are driving in a region with right or left
hand trac. In situations where GPS data is unavailable
(for example, if there is inadequate signal), engaging the
turn signal near an exit does not cause Trac-Aware
Cruise Control to slow down Model 3.
When enabled while on a highway interchange or o-
ramp, Trac-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 touch the
plus (+) or minus (-) button on the touchscreen. The
new set speed is maintained for the duration of the
interchange or
o-ramp (unless you override it or cancel
Trac-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
dierent 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
insucient data), Trac-Aware Cruise Control may
not automatically reduce the set speed on the
highway interchange or o-ramp. Do not rely on
Trac-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 3 and a vehicle traveling ahead of you,
press the steering wheel's right scroll button to the left
or right to 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 3, from its current
location, to reach the location of the rear bumper of the
vehicle ahead of you.
