Restricted Roads
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 5 mph
(10 km/h). In situations where the speed limit
can not be detected, speed is limited to
45 mph (70 km/h). When Autosteer is
engaged on a restricted road, it reduces the
speed to be within these limits, even if the set
cruising speed is higher. The instrument panel
displays a message indicating that you are
driving on a restricted road. 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 restricted road, or
disengage Autosteer by using the steering
wheel, Model S resumes cruising at the set
speed.
Hold Steering Wheel
Autosteer uses data from the camera, sensors,
and GPS system to determine where to drive.
It also requires you to hold the steering wheel.
When entering a curve or driving at a high
speed, if Autosteer does not detect your
hands on the steering wheel, it displays the
following message on the instrument panel
and eventually sounds a chime:
When you see this message, you may need to
tighten your grip on the steering wheel. When
your hands are detected, Autosteer resumes
normal operation.
Note: Be careful not to apply any steering.
Doing so cancels Autosteer.
If Autosteer does not detect your hands on
the steering wheel, the Hold Steering Wheel
request escalates by sounding two additional
chimes. The chimes increase in frequency until
Autosteer detects your hands. If no action is
taken, Autosteer begins to decelerate Model S
and displays the following message on the
instrument panel:
Driver Assistance
Autosteer will eventually decelerate Model S
to a full stop and then turn on the hazard
warning flashers.
Take Over Immediately
In situations where Autosteer is unable to
steer Model S, Autosteer sounds a warning
chime and displays the following message on
the instrument panel:
When you see this message, TAKE OVER
STEERING IMMEDIATELY.
Canceling Autosteer
Autosteer cancels when:
• You start steering manually.
• 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 (90 mph/150 km/h) is exceeded.
• You shift out of the Drive gear.
• An Automatic Emergency Braking event
occurs (see Collision Avoidance Assist
page 85).
When Autosteer cancels, the Autosteer icon is
gray to indicate that Autosteer is no longer
active.
Note: If Autosteer cancels because you started
steering manually, 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 > Cancel.

intended in the following situations:
