Restricted Speed
Autosteer is intended for use on freeways and
highways where access is limited by entry and
exit ramps. When using Autosteer on
residential roads, a road without a center
divider, or a road where access is not limited,
Autosteer limits the driving speed. The
maximum driving speed is calculated based
on the detected speed limit plus 10 km/h. In
situations where the speed limit cannot be
detected, speed is limited to 70 km/h. When
Autosteer is engaged in these situations, it
reduces your driving speed and your set
speed to be within these limits. You can
manually accelerate to exceed the limited
speed, but when you release the accelerator
pedal, Autosteer slows Model S to the limited
speed. 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, sensors,
and GPS to determine how best to assist you
in steering Model S. 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 white
light appears around the instrument panel and
the following message is displayed on the
instrument panel:
Autosteer detects your hands by recognizing
light resistance as the steering wheel turns or
from you manually turning the steering wheel
very lightly (i.e., without enough force to
retake control). 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.
Driver Assistance
If you repeatedly ignore hands-on prompts,
Autosteer displays the following message and
becomes disabled for the rest of the drive. 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 after
you shift the vehicle into Park.
Autosteer is Aborting
In situations where Autosteer is unable to
assist in steering Model S, Autosteer aborts,
sounds a warning chime, and displays the
following message on the instrument panel:
Canceling Autosteer
Autosteer cancels when:
• You apply rotational force to the steering
wheel (even a slight amount).
• You press the brake pedal.
• You push the cruise control lever away
from you.
• You unbuckle the driver's seat belt.
• The maximum speed that Autosteer
supports (150 km/h) is exceeded.
• You shift out of the Drive gear.
• An Automatic Emergency Braking event
occurs (see Collision Avoidance Assist
page 81).
When Autosteer cancels, the Autosteer icon is
gray to indicate that Autosteer is no longer
active.
Note: If Autosteer cancels because you
applied rotational force to the steering wheel,
Traffic-Aware Cruise Control remains active.
Disengage Traffic-Aware Cruise Control as you
normally would, by pressing the brake or
briefly pushing the cruise control lever away
from you.
To disable Autosteer so it is no longer
available, touch Controls > Settings > Driver
Assistance > Autosteer > OFF.
