Warning: Auto Lane Change is designed
to be used only when driving on
restricted-access highways (i.e. with on-
ramps and o-ramps).
If you have purchased the optional Enhanced
Autopilot or Full Self-Driving Capability
packages, 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
Trac-Aware
Cruise Control and Autosteer are active, Auto
Lane Change intelligently steers Model 3 into
an adjacent driving lane. Using the forward
looking 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.
Warning: It is the driver's responsibility to
determine whether a lane change is safe
and appropriate. Auto Lane Change
cannot detect oncoming trac in the
target lane, especially fast moving
vehicles from the rear. Therefore, before
initiating a lane change, always check
blind spots, lane markings, and the
surrounding roadway to
confirm it is safe
and appropriate to move into the target
lane.
Warning: Never depend on Auto Lane
Change to determine an appropriate
driving path. Drive attentively by
watching the road and trac ahead of
you, checking the surrounding area, and
monitoring the touchscreen for warnings.
Always be prepared to take immediate
action.
Warning: Do not use Auto Lane Change
on city streets or on roads where trac
conditions are constantly changing and
where bicycles and pedestrians are
present.
Warning: The performance of Auto Lane
Change depends on the ability of the
camera(s) to recognize lane markings.
Warning: Do not use Auto Lane Change
on winding roads with sharp curves, on
icy or slippery roads, or when weather
conditions (such as heavy rain, snow, fog,
etc.) may be obstructing the view from
the camera(s) or sensors.
Warning: Failure to follow all warnings
and instructions can result in serious
property damage, injury or death.
Operating Auto Lane Change
Before you can operate Auto Lane Change,
you must enable it by touching Controls >
Autopilot > Auto Lane Change > ON.
Note: Before you can turn on Auto Lane
Change, you must turn on Autosteer (see
Autosteer on page 66). Without Autosteer,
Auto Lane Change cannot operate.
Note: Your chosen setting is retained until you
manually change it.
To change lanes using Auto Lane Change:
1. Perform visual checks to make sure it is
safe and appropriate to move into the
target lane.
2. Engage the appropriate turn signal.
3. Disengage the turn signal after you are in
the target lane.
Auto Lane Change moves Model 3 into the
adjacent lane in the direction indicated by the
turn signal, provided the following conditions
are met:
• The Auto Lane Change setting is turned
on.
• The turn signal is engaged.
• Autosteer is actively steering Model 3.
• The ultrasonic sensors do not detect a
vehicle or obstacle up to the center of the
target lane.
• The lane markings indicate that a lane
change is permitted.
• The view of the camera(s) is not
obstructed.
• Lane Assist does not detect a vehicle in
the blind spot (see Lane Assist on page
73).
• Midway through the lane change, Auto
Lane Change can detect the outside lane
marking of the target lane.
• Driving speed is at least 30 mph
(45 km/h).
As the lane change is in progress, Overtake
Acceleration is activated, allowing Model 3 to
accelerate closer to a vehicle in front (see
Overtake Acceleration on page 64). Midway
through the lane change, Auto Lane Change
must be able to detect the target lane's
outside lane marking. If this lane marking
cannot be detected, both Auto Lane Change
and Autosteer will cancel.
