never depend on Overtake Acceleration
to increase your driving speed.Warning: Overtake Acceleration increases
your driving speed whenever the
appropriate turn signal is engaged, and
accelerates Model S closer to the vehicle
ahead. Although
Traffic-Aware Cruise
Control continues to maintain distance
from the vehicle ahead, it is important to
be aware that your selected following
distance is reduced when Overtake
Acceleration is active, particularly in cases
where it may not be your intention to
overtake the vehicle you are following.
Canceling and Resuming
To manually cancel
Traffic-Aware Cruise
Control, briefly push the cruise control lever
away from you or press the brake pedal. The
speedometer icon on the instrument panel
turns gray to indicate that
Traffic-AwareCruise Control is not actively controlling your
speed.
To resume cruising at the previously set
speed, briefly pull the cruise control lever
toward you.
To resume cruising at the current driving speed, move the cruise control lever up or
down, then release
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 Traffic-
Aware Cruise Control (see Regenerative
Braking on page 60).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:

Note: Autosteer is a BETA feature.
If your Model S is equipped with Driver
Assistance components (see About Driver
Assistance on page 73), and you have
purchased the optional Enhanced Autopilot or
Full Self-Driving Capability packages, you can
use Autosteer to manage steering and speed under certain circumstances. Autosteer builds
upon
Traffic-Aware Cruise Control (see Traffic-Aware Cruise Control on page 76),
intelligently keeping Model S in its driving lane
when cruising at a set speed. Using the
vehicle

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 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.
Warning: Autosteer is not designed to,
and will not, steer Model S 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

Autosteer cancels when:

Warning: Auto Lane Change is designed
to be used only when driving on
restricted-access highways (i.e. with on-
ramps and
off-ramps).
If your Model S is equipped with Driver
Assistance components (see About Driver
Assistance on page 73), and you have
purchased the optional Enhanced Autopilot or
Full Self-Driving Capability packages, 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(s), the
radar sensor, and ultrasonic sensors, Model S detects lane markings and the presence ofother vehicles.
Auto Lane Change is designed for use on restricted-access highways with visible lanemarkings and under relatively predictable
circumstances in which minimal steering and
driver intervention is needed.
Warning: It is the driver

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 79). Midway
through the lane change, Auto Lane Change must be able to detect the target lane

If your Model S is equipped with Driver
Assistance components (see About Driver
Assistance on page 73), and you have
purchased the optional Enhanced Autopilot or
Full Self-Driving Capability package, Autopark
