off-ramp and as a result, the navigation
system will re-route you to your destination.
Warning: Navigate on Autopilot may not
always attempt to exit at an off-ramp or
change lanes, even when an exit or lane
change is determined by the navigation
route. Always remain alert and be
prepared to manually steer onto an off-
ramp, or make a lane change to prepare
for, or to exit at, an off-ramp or
interchange.
Be Ready to Assist
When attempting to change lanes or
maneuver Model S, or when approaching
construction zones, Navigate on Autopilot
may be unable to determine the appropriate
driving lane (for example, complex clover leafs
and multi-lane off-ramps) and the instrument
panel displays an alert indicating that
Navigate on Autopilot is trying to maneuver
and may require assistance. When you see the
message, be prepared to take immediate
action to ensure that it is safe and appropriate
to complete the lane change or maneuver.
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.
Autopilot
• 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).
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 S appropriately. Always drive
attentively and be prepared to take
immediate action.
