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.
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 Y 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 Y in a driving path that is
oset from the center of the lane.
Warning: Autosteer is not designed to,
and will not, steer Model Y 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 Y at all times.
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 can vary depending on
whether or not you've specified a speed limit
oset. Although you will be unable to increase
the cruising speed, you can select a more
restrictive cruising speed by reducing the
speed limit oset, if applicable, (see
Controlling Speed Assist on page 113) or by
manually reducing the set cruising speed (see
Changing the Set Speed on page 87).
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 Y 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.
Hold Steering Wheel
Autosteer uses data from the camera(s),
sensors, and GPS to determine how best to
steer Model Y. 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:
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). Autosteer also qualifies your hands
as being detected if you engage a turn signal
or use a button or scroll wheel on the steering
wheel.
Note: When your hands are detected, the
message disappears and Autosteer resumes
normal operation.
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.
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.
For the rest of the drive, you must steer
manually. Autosteer is available again on your
next drive (after you stop and shift Model Y
into Park).
Take Over Immediately
In situations where Autosteer is unable to
steer Model Y, Autosteer sounds a warning
chime and displays the following message on
the touchscreen:
