Autosteer
NOTE: To initiate Autosteer when there is no
vehicle in front of you, you must be driving at
least 18 mph (30 km/h) on a roadway with
visible lane markings. If a vehicle is detected
ahead of you, you can initiate Autosteer at
any speed under 90 mph (150 km/h), even
when stationary (if you are at least 5 feet (150
cm) away from the vehicle).
In situations where the speed limit cannot be
detected when Autosteer is engaged,
Autosteer reduces your driving speed and
limits the set speed to 45 mph (70 km/h).
Although you can manually accelerate to
exceed the limited speed, Model 3 may not
brake for detected obstacles. Autosteer slows
down to the limited speed when you release
the accelerator pedal. When you leave the
road, or disengage Autosteer by using the
steering wheel, you can increase your set
speed again, if desired.
The touchscreen displays a message
indicating that Autosteer is temporarily
unavailable if you attempted to engage
Autosteer when driving at a speed that is not
within the speed required for Autosteer to
operate. Autosteer may also be unavailable if
it is not receiving adequate data from the
camera(s) or sensors.
Hold Steering Wheel
Autosteer uses data from the camera(s),
sensors, and GPS to determine how best to
assist you in steering Model 3. When active,
Autosteer requires you to hold the steering
wheel. If it does not detect your hands on the
steering wheel for a period of time, a flashing
blue light appears at the top of the car status
section of the touchscreen and the following
message displays:
If Autosteer is unable to detect lane markings,
the driving lane is determined based on the
vehicle you are following.
In most cases, Autosteer attempts to center
Model 3 in the driving lane. However, if the
sensors detect the presence of an obstacle
(such as a vehicle or guard rail), Autosteer
may steer Model 3 in a driving path that is
offset from the center of the lane.
WARNING: Autosteer is not designed
to, and will not, steer Model 3 around
objects partially or completely in the
driving lane. Always watch the road in
front of you and stay prepared to take
appropriate action. It is the driver's
responsibility to be in control of Model
3 at all times.
Autosteer detects your hands by recognizing
light resistance as the steering wheel turns, or
from you manually turning the steering wheel
very lightly (without enough force to retake
control).
NOTE: When your hands are detected, the
message disappears and Autosteer resumes
normal operation.
WARNING: Steering is limited when
Autosteer is enabled. Therefore, Model
3 may not be able to handle tight
turns. Be prepared to take control of
the vehicle at all times.
NOTE: Autosteer may also sound a chime at
the same time that the message is initially
displayed.
Autosteer requires that you pay attention to
your surroundings and remain prepared to
take control at any time. If Autosteer still does
not detect your hands on the steering wheel,
the request escalates by sounding chimes
that increase in frequency.
Restricted Speed
Autosteer is intended for use only by a fully
attentive driver on freeways and highways
where access is limited by entry and exit
ramps. If you choose to use Autosteer on
residential roads, a road without a center
divider, or a road where access is not limited,
Autosteer may limit the maximum allowed
cruising speed and the touchscreen displays a
message indicating that speed is restricted.
The restricted speed will be the speed limit of
the road plus 5 mph (10 km/h).
If you repeatedly ignore Autosteer's prompts
for having your hands on the steering wheel,
Autosteer disables for the rest of the drive
and displays the following message. If you
don't resume manual steering, Autosteer
sounds a continuous chime, turns on the
warning flashers, and slows the vehicle to a
complete stop.
