Autosteer
Limitations
Autosteer is particularly unlikely to operate as
intended in the following situations:
• Autosteer is unable to accurately
determine lane markings due to poor
visibility (heavy rain, snow, fog, etc.), or an
obstructed, covered, or damaged camera
or sensor.
• When driving on hills.
• When approaching a toll booth.
• The road has sharp curves or is
excessively rough.
• Bright light (such as direct sunlight) is
interfering with the camera's view.
• The sensors are affected by other
electrical equipment or devices that
generate ultrasonic waves.
Warning: Many unforeseen circumstances
can impair the operation of Autosteer.
Always keep this in mind and remember
that as a result, Autosteer may not assist
in steering Model S appropriately. Always
drive attentively and be prepared to take
immediate action.
