Auto Lane Change - Tesla S Owner's Manual

If Model S is equipped with Driver Assistance
components (see
page 62), and you have purchased the
optional Autopilot Tech Package, you can use
Auto Lane Change to move Model S into an
adjacent lane. When both Traffic-Aware Cruise
Control and Autosteer are active, Auto Lane
Change intelligently assists you in steering
Model S into an adjacent driving lane. Using
the forward looking camera, the radar sensor,
and the ultrasonic sensors, Autosteer detects
lane markings and the presence of other
vehicles.
Auto Lane Change is designed for use on
highways and main roads 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 can
not detect oncoming traffic 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 traffic ahead of
you, checking the surrounding area, and
monitoring the instrument panel for
warnings. Always be prepared to take
immediate action.
Warning: Do not use Auto Lane Change
on city streets or on roads where traffic
conditions are constantly changing and
where bicycles and pedestrians are
present.
Warning: The performance of Auto Lane
Change depends on the forward looking
camera's ability 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 or sensors.

Operating Auto Lane Change
on
Before you can operate Auto Lane Change,
you must enable it by touching Controls >
Settings > Driver Assistance > Auto Lane
Change > On.
Note: Before you can turn on Auto Lane
Change, you must turn on Autosteer (see
Autosteer on page 70). Without Autosteer,
Auto Lane Change can not operate.
Note: Your chosen setting is retained until you
manually change it. It is also saved in your
driver profile.
To change lanes using Auto Lane Change:
• Perform visual checks to make sure it is
safe and appropriate to move into the
target lane.
• Engage the turn signal and initiate the
lane change by having your hands on the
steering wheel.
Auto Lane Change assists in moving Model S
into the adjacent lane in the direction
indicated by the turn signal, provided the
following conditions are met:
• Auto Lane Change detected your hands
on the steering wheel.
• The Auto Lane Change setting is turned
on.
• The turn signal is engaged.
• Autosteer is actively steering Model S.
• The ultrasonic sensors detect no vehicle
or obstacles up to the center of the target
lane.
• The lane markings indicate that a lane
change is permitted.
• The camera's view is not obstructed.
• Lane Assist does not detect a vehicle in
the blind spot (see
79).
• Midway through the lane change, Auto
Lane Change can detect the outside lane
marking of the target lane.
• Driving speed is at least 45 km/h.
As the lane change is in progress, Overtake
Acceleration is activated, allowing Model S to
accelerate closer to a vehicle in front (see
Overtake Acceleration
through the lane change, Auto Lane Change
must be able to detect the target lane's
outside lane marking. If this lane marking can
not be detected, both Auto Lane Change and
Autosteer will cancel.
Note: Auto Lane Change assists in moving the
vehicle one lane at a time. Moving into an
