NOTE:
Auto Lane Change cancels if the lane
change cannot be completed in five seconds.
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 turn signal is engaged.
• The ultrasonic sensors and Autopilot
cameras 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.
• Your vehicle does not detect another
vehicle in its blind spot.
• 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 on page 96
). Midway
through the lane change, Auto Lane Change
must detect the target lane's outside lane
marking. If this lane marking cannot be
detected, the lane change is aborted and
Model S returns to its original driving lane.
NOTE:
Auto Lane Change assists in moving
Model S one lane at a time. Moving into an
additional lane requires you to engage the
turn signal a second time after the first lane
change is complete.
When using Auto Lane Change, it is
important to monitor its performance by
watching the driving path in front of you and
the surrounding area. Stay prepared to take
over steering at any time. As you are crossing
over into the adjacent lane, the instrument
panel displays the lane marking as a dashed
blue line. Once in your new lane, lane
markings are displayed as solid blue lines
again.
In situations where Auto Lane Change is
unable to operate at optimal performance, or
cannot operate due to inadequate data, the
instrument panel displays a series of
warnings. Therefore, when using Auto Lane
Change, always pay attention to the
instrument panel and be prepared to
manually steer Model S.
Limitations
Autosteer and its associated functions are
particularly unlikely to operate as intended
when:
• Autosteer is unable to accurately
determine lane markings. For example,
lane markings are excessively worn, have
visible previous markings, have been
adjusted due to road construction, are
changing quickly (lanes branching off,
crossing over, or merging), objects or
landscape features are casting strong
shadows on the lane markings, or the
road surface contains pavement seams or
other high-contrast lines.
• Visibility is poor (heavy rain, snow, fog,
etc.) or weather conditions are interfering
with sensor operation.
• A camera(s) or sensor(s) is obstructed,
covered, or damaged.
• Driving on hills.
• Approaching a toll booth.
• Driving on a road that has sharp curves or
is excessively rough.
• Bright light (such as direct sunlight) is
interfering with the view of the camera(s).
• The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
• A vehicle is detected in your blind spot
when you engage the turn signal.
• Model S is being driven very close to a
vehicle in front of it, which is blocking the
view of the camera(s).
