lane of travel, causing Model 3 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 3 to exceed your set speed
(and potentially the road

(whichever is greater) when you move the
gear lever fully down once then release.
Note: If Speed Assist is unable to determine a
speed limit, your set speed does not change
when you move the gear lever fully down once
then release.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, roll the right scroll
wheel up (to increase) or down (to decrease)
the set speed until your desired set speed is
displayed. Slowly rolling the scroll wheel changes the set speed in 1 mph (1 km/h)
increments and quickly rolling the scroll wheel
changes the set speed to the closest 5 mph (5
km/h) increment.
You can also use the touchscreen to change
the set speed by touching the plus ( +) or
minus ( -) next to the displayed set speed. A
quick tap changes the set speed by 1 mph (1
km/h) and a press and hold changes the set
speed to the closest 5 mph (5 km/h)
increment. To increase/decrease to the next
increment, you must release the plus ( +) or
minus ( -) then press it again.
To cruise at the speed limit that is currently
being determined by Speed Assist (including
any
offsets that you have set), move the gear
lever fully down once then release. See Speed
Assist on page 79.
Note: It may take a few seconds for Model 3 to
reach the new cruising speed, assuming Model
3 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 3 towards the vehicle ahead. By momentarily holding theturn 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:

Warning: Overtake Acceleration increases
your driving speed whenever the
appropriate turn signal is engaged, and
accelerates Model 3 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, move the gear lever up and release or
press the brake pedal. The speedometer icon
on the touchscreen turns gray to indicate that
Traffic-Aware Cruise Control is not actively
controlling your speed.
Note: If you hold the gear lever upward for
more than 1 second, Model 3 shifts into Neutral
after canceling
Traffic-Aware Cruise Control.
To re-enable cruising at the current driving
speed, move the gear lever fully down once then release.
Note: When Traffic-Aware Cruise Control
cancels, Model 3 does not coast. Instead,
regenerative braking slows down Model 3 in
the same way as when you move your foot offthe accelerator when driving without Traffic-
Aware Cruise Control (see Regenerative
Braking on page 49).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:

Traffic-Aware Cruise Control is
operating and is either maintaining
the set speed (no vehicle in front) or
is maintaining a chosen following
distance from a vehicle ahead (up to
the set speed).Model 3 has fully stopped but is in a
HOLD state. If safe, press the
accelerator pedal to resume cruising
at the set speed.
Limitations
Traffic-Aware Cruise Control is particularly
unlikely to operate as intended in the
following types of situations:

Note: Autosteer is a BETA feature.
If you have purchased the optional Enhanced Autopilot or Full Self-Driving Capabilitypackages, you can use Autosteer to manage
steering and speed under certain
circumstances. Autosteer builds upon
Traffic-
Aware Cruise Control (see Traffic-AwareCruise Control on page 61), intelligently
keeping Model 3 in its driving lane when
cruising at a set speed. Using the vehicle

In most cases, Autosteer attempts to centerModel 3 in the driving lane. However, if the
sensors detect the presence of an obstacle (such as a vehicle or guard rail), Autosteer
may steer Model 3 in a driving path that is
offset from the center of the lane.
Warning: Autosteer is not designed to,
and will not, steer Model 3 around objects
partially or completely in the driving lane.
Always watch the road in front of you and stay prepared to take appropriate action.It is the driver

Warning: Auto Lane Change is designed
to be used only when driving on
restricted-access highways (i.e. with on-
ramps and
off-ramps).
If you have purchased the optional Enhanced Autopilot or Full Self-Driving Capabilitypackages, you can use Auto Lane Change to
move Model 3 into an adjacent lane without
moving the steering wheel (which would
cancel Autosteer). When both
Traffic-AwareCruise Control and Autosteer are active, Auto
Lane Change intelligently steers Model 3 into an adjacent driving lane. Using the forwardlooking camera(s), the radar sensor, and
ultrasonic sensors, Model 3 detects lane markings and the presence of other vehicles.
Auto Lane Change is designed for use on
restricted-access highways with visible lane markings and under relatively predictable
circumstances in which minimal steering and
driver intervention is needed.
