Limitations
Traffic-Aware Cruise Control is particularly
unlikely to operate as intended in the
following types of situations:
Page 74 of 190

Note: Autosteer is a BETA feature in Release
7.1.
If Model S is equipped with Driver Assistance
components (see About Driver Assistance on
page 65), and you have purchased the optional Autopilot Tech Package, you can use
Autosteer to manage steering and speed under certain circumstances. Autosteer builds
upon
Traffic-Aware Cruise Control,
intelligently keeping Model S in its driving lane
when cruising at a set speed. Using the
forward looking camera, the radar sensor, and
the ultrasonic sensors, Autosteer detects lane
markings and the presence of vehicles and
objects, steering Model S based on the lanemarkings and the vehicle directly in front of
you.
Warning: Autosteer is a hands-on feature.
You must keep your hands on the steering
wheel at all times.Warning: Autosteer is intended for use
only on highways and limited-access
roads with a fully attentive driver. When using Autosteer, hold the steering wheel
and be mindful of road conditions and
surrounding
traffic. Do not use Autosteer
on city streets or in areas where bicyclists
or pedestrians may be present. Never
depend on Autosteer to determine an
appropriate driving path. Always be
prepared to take immediate action.
Failure to follow these instructions could
cause serious property damage, injury or
death.
Operating Autosteer
Before you can operate Autosteer, you must
enable it by touching Controls > Settings >
Driver Assistance > Autosteer > Enable.
To indicate that Autosteer is available (but not actively steering Model S), the instrumentpanel displays a gray Autosteer icon on theright side of the driving speed as shown here:
To initiate Autosteer, pull the cruise control
lever toward you twice in quick succession. Autosteer
briefly displays a message on the
instrument panel reminding you to pay
attention to the road and be ready to take
over at any time. To indicate that Autosteer is now actively steering Model S, the instrument
panel displays the Autosteer icon in blue.
When Autosteer is able to detect lane
markings, it also displays the driving lane in blue:
Note: To initiate Autosteer, 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, even when stationary.
Note: In most cases, Autosteer attempts to
center Model S in the driving lane. However, if
the sensors detect the presence an obstacle (such as a vehicle or guard rail), Autosteer
may steer Model S in a driving path that is
offset from the center of the lane.
Note: In situations where you attempt to
engage Autosteer but you are not driving
within the required driving speed for Autosteer to operate, or Autosteer is not
receiving adequate data from the camera or
sensors, a message displays on the instrument
panel indicating that Autosteer is temporarily
unavailable.

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 centerdivider, 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 totighten 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:
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 warningchime and displays the following message on
the instrument panel:
When you see this message, TAKE OVER STEERING IMMEDIATELY.
Canceling Autosteer Autosteer cancels when:

If Model S is equipped with Driver Assistance
components (see About Driver Assistance on
page 65), and you have purchased the
optional Autopilot Tech Package, you can use
Auto Lane Change to move Model S into an adjacent lane without touching the steering
wheel (which would cancel Autosteer). When both
Traffic-Aware Cruise Control and
Autosteer are active, Auto Lane Change
intelligently steers Model S into an adjacent
driving lane. Using the forward looking camera, the radar sensor, and the ultrasonic
sensors, Autosteer detects lane markings and
the presence of other vehicles.
Auto Lane Change is designed for use on
highways and main roads with visible lane
markings and under relatively predictable circumstances in which minimal steering and
driver intervention is needed.
Warning: It is the driver
Page 78 of 190
midway through the lane change, both
Auto Lane Change and Autosteer will cancel. The instrument panel displays a
message instructing you to take over the
steering wheel immediately.
When Auto Lane Change is active, it is
important to monitor its performance by
watching the driving path in front of you. Stay
prepared to take over steering at any time. On the instrument panel, the lane you are crossing
over displays as a dashed blue line and once in your new lane, the lane markings display as
solid blue lines.
In situations where Auto Lane Change is
unable to operate at optimal performance, or
can not operate due to inadequate data, the
instrument panel displays a series of warnings.
Therefore, when using Auto Lane Change,
always pay attention to the instrument panel
and be prepared to manually steer Model S.
Warning: When Auto Lane Change is
actively steering Model S, the steering
wheel moves accordingly. Any
