Owner's Guide

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 touchscreen
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
touchscreen displays a series of warnings.
Therefore, when using Auto Lane Change,
always pay attention to the touchscreen and
be prepared to manually steer Model 3.
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 o,
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 aected 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 3 is being driven very close to a
vehicle in front of it, which is blocking the
view of the camera(s).
Warning:
Many unforeseen circumstances
can impair the operation of Autosteer.
Always keep this in mind and remember
that as a result, Autosteer may not steer
Model 3 appropriately. Always drive
attentively and be prepared to take
immediate action.
