To increase/decrease speed by 1 mph (1
km/h), move the lever up or down to the firstposition and release. To increase/decrease
speed to the closest 5 mph (5 km/h)
increment, move the lever up/down to the second position and release. For example, if
you are traveling at 57 mph and you move the
lever up to the second position and release,
the speed increases to 60 mph. You can also increase/decrease speed by holding the lever
in the full up/down position and releasing
when the desired speed displays below the
cruise control icon.
To cruise at the speed limit that is currently
being determined by Speed Assist (including
any
offsets that you have set), pull the cruise
control lever toward you and hold momentarily (about half a second). See Speed
Assist on page 91.
Note: It may take a few seconds for Model S to reach the new cruising speed.
Note: The maximum set speed is 90 mph
(150 km/h). However, it is the driver

To resume cruising at the previously set
speed, briefly pull the cruise control lever
toward you.
Note: Depending on date of manufacture,
some Model S vehicles have a button on the end of the cruise control lever. Pressing this
button when cruise control is active cancels
cruise control.
Note: When
Traffic-Aware Cruise Control
cancels, Model S does not coast. Instead,
regenerative braking slows down Model S in
the same way as when you move your foot
offthe accelerator when driving without cruise
control (see Regenerative Braking on page
58).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:

Note: Autosteer is a BETA feature.
If Model S is equipped with Driver Assistance
components (see About Driver Assistance on
page 68), 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, assisting you in steering Model S
based on the lane markings 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, in construction zones, 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 instrument
panel displays a gray Autosteer icon on the right 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 have your hands on
the steering wheel. To indicate that Autosteer
is now actively assisting in steering Model S, the instrument panel displays the Autosteericon in blue. When Autosteer is able to detectlane markings, it also displays the driving lane
in blue:
Note: In situations where Autosteer is unable
to detect lane markings, the driving lane is
determined based on the vehicle you are
following. In these situations, the car in front
of you is highlighted in blue.
Note: To initiate Autosteer, you must be
driving at least 5 mph (8 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 of 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 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 centerdivider, or a road where access is not limited,
Autosteer limits the driving speed. Keep in
mind however, that Autosteer is intended for
use only on highways and limited-access roads
with a fully attentive driver. The maximum
driving speed is calculated based on the
detected speed limit plus 5 mph (10 km/h). In situations where the speed limit cannot be
detected, speed is limited to 45 mph
(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 steeringwheel, 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 toretake 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 totake control at any time. If Autosteer still doesnot detect your hands on the steering wheel,the request escalates by sounding chimes that
increase in frequency.
If you repeatedly ignore hands-on prompts,
Autosteer displays the following message and
becomes disabled for the rest of the drive. If
you don

Limitations
Autosteer is particularly unlikely to operate as intended in the following situations:
Page 79 of 186
If Model S is equipped with Driver Assistance
components (see About Driver Assistance on
page 68), and you have purchased the
optional Autopilot Tech Package, you can use
Auto Lane Change to move Model S into an adjacent lane. When both
Traffic-AwareCruise Control and Autosteer are active, Auto
Lane Change intelligently assists you in
steering 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 predictablecircumstances in which minimal steering and
driver intervention is needed.
Warning: It is the driver
Page 80 of 186
As the lane change is in progress, Overtake
Acceleration is activated, allowing Model S to accelerate closer to a vehicle in front (see
Overtake Acceleration on page 73). Midway
through the lane change, Auto Lane Change must be able to detect the target lane
