• The maximum speed that Autosteer
supports–90 mph (150 km/h)–is
exceeded.
• You move the gear lever upwards.
• An Automatic Emergency Braking event
occurs (see Collision Avoidance Assist on
page 75).
When Autosteer cancels, it sounds chimes and
the Autosteer icon either turns gray to
indicate that Autosteer is no longer active, or
disappears to indicate that it is not currently
available.
Note: If Autosteer cancels because you
started steering manually,
Trac-Aware Cruise
Control remains active. Disengage
Trac-
Aware Cruise Control as you normally would,
by moving the gear lever upward or pressing
the brake pedal.
Note: If you hold the gear lever upward for
more than 1 second, Model 3 shifts into Neutral
after canceling Autosteer.
To disable Autosteer so it is no longer
available, touch Controls > Autopilot >
Autosteer (Beta) > OFF.
Limitations
Autosteer is 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.).
• 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
aected 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 steer
Model 3 appropriately. Always drive
attentively and be prepared to take
immediate action.
