Owner's Guide

When the cruising speed is
set, the speedometer icon on
the touchscreen turns blue
and displays the set cruising
speed.
Note: Moving the gear level fully down twice in
quick succession engages Autosteer
(assuming it has been enabled as described in
Autosteer on page 75) and the set speed
changes to either your current driving speed,
or the current set speed (displayed in the
icon), whichever is greater.
Note: The minimum speed you can set is
30 km/h and the maximum is 150 km/h. It is
the driver's responsibility to cruise at a safe
speed based on road conditions and speed
limits.
Warning: When cruising at the speed
limit, the cruising speed does not change
when the speed limit changes. If your
driving speed is at or below the new
speed limit, move the lever up to cancel
Trac-Aware Cruise Control, then move it
back down again to re-initiate and cruise
at the new speed limit. You can also
manually adjust your cruising speed (see
Changing the Set Speed on page 71).
Warning: Do not rely on Trac-Aware
Cruise Control or Speed Assist to
determine an accurate or appropriate
cruising speed. Always cruise at a safe
speed based on road conditions and
applicable speed limits.
Cruising at the Set Speed
Trac-Aware Cruise Control maintains your
set cruising speed whenever a vehicle is not
detected in front of Model 3. When cruising
behind a detected vehicle, Trac-Aware
Cruise Control accelerates and decelerates
Model 3 as needed to maintain a chosen
following distance (see Adjust the Following
Distance on page 72), up to the set speed.
Trac-Aware Cruise Control also adjusts the
cruising speed when entering and exiting
curves.
You can manually accelerate at any time when
cruising at a set speed, but when you release
the accelerator, Trac-Aware Cruise Control
resumes cruising at the set speed.
Note: When Trac-Aware Cruise Control is
actively slowing down Model 3 to maintain the
selected distance from the vehicle ahead,
brake lights turn on to alert other road users
that you are slowing down. You may notice
slight movement of the brake pedal. However,
when Trac-Aware Cruise Control is
accelerating Model 3, the accelerator pedal
does not move.
Warning: Trac-Aware Cruise Control
may occasionally cause Model 3 to brake
when not required or when you are not
expecting it. This can be caused by
closely following a vehicle ahead,
detecting vehicles or objects in adjacent
lanes (especially on curves), etc.
Warning: Due to limitations inherent in
the onboard GPS (Global Positioning
System), you may experience situations in
which Trac-Aware Cruise Control slows
down the vehicle, especially near highway
exits where a curve is detected and/or
you are actively navigating to a
destination and not following the route.
Warning: Trac-Aware Cruise Control
cannot detect all objects and, especially
in situations when you are driving over
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 Trac-Aware
Cruise Control to avoid a collision can
result in serious injury or death. In
addition, Trac-Aware Cruise Control
may react to vehicles or objects that
either do not exist or are not in the lane
of travel, causing Model 3 to slow down
unnecessarily or inappropriately.
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.
