Page 68 of 190

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, the forward lookingcamera and the radar sensor are designed to
determine when there is a vehicle in front of
you in the same lane. If the area in front of Model S is clear,
Traffic-Aware Cruise Control
maintains a set driving speed. When a vehicle is detected,
Traffic-Aware Cruise Control is
designed to slow down Model S as needed to maintain a selected time-based distance from
the vehicle in front, up to the set speed.
Traffic-Aware Cruise Control does not
eliminate the need to watch the road in front
of you and to apply the brakes when needed.
Traffic-Aware Cruise Control is primarily
intended for driving on dry, straight roads,
such as highways and freeways. It should not
be used on city streets.
Warning: Traffic-Aware Cruise Control is
designed for your driving comfort and
convenience and is not a collision warning or avoidance system. It is your
responsibility to stay alert, drive safely,
and be in control of the vehicle at all
times. Never depend on
Traffic-AwareCruise Control to adequately slow down
Model S. Always watch the road in front
of you and be prepared to take corrective
action at all times. Failure to do so can
result in serious injury or death.
Warning: Do not use Traffic-Aware Cruise
Control on city streets or on roads where
traffic conditions are constantly changing
and where bicycles and pedestrians are
present.
Warning: Do not use Traffic-Aware Cruise
Control on winding roads with sharp
curves, on icy or slippery road surfaces, or
when weather conditions (such as heavy
rain, snow, fog, etc) make it inappropriate
to drive at a consistent speed.
Traffic-
Aware Cruise Control does not adapt
driving speed based on road and driving
conditions.
Operating Traffic-Aware Cruise
ControlThe instrument panel
displays a gray speedometer
icon on the left side of the
driving speed to indicate
that
Traffic-Aware Cruise
Control is available but the
cruising speed has not been
set. Unless a vehicle is
detected ahead of you, you
must be driving at least
18 mph (30 km/h) to use
Traffic-Aware Cruise Control.
If a vehicle is detected ahead
of you, you can use
Traffic-
Aware Cruise Control at any
speed, even when stationary.
When driving at your desired speed, set the
cruising speed by moving the cruise control
lever up or down (or pulling it
briefly toward
you), then releasing.
The speedometer icon on the
instrument panel turns blue
and displays the set speed to
indicate that
Traffic-AwareCruise Control is actively
maintaining the set speed.
You can now release the accelerator pedal and
allow Traffic-Aware Cruise Control to maintain
your set speed. When no vehicle is detected ahead,
Traffic-Aware Cruise Control maintains
the set speed. If a vehicle is detected, Traffic-
Aware Cruise Control maintains your chosen
following distance, up to the set speed,
accelerating and decelerating Model S as
needed. When the vehicle you are following is
no longer detected,
Traffic-Aware Cruise
Control accelerates back to the set speed.
Traffic-Aware Cruise Control also adjusts the
speed as appropriate when entering and
exiting curves.
Traffic-Aware Cruise Control

You can accelerate at any time when driving ata set speed using Traffic-Aware Cruise
Control. But when you release the accelerator,
Model S returns to the set speed.
When following a vehicle,
Traffic-Aware Cruise
Control remains active at low speeds, even if
Model S comes to a standstill while following a
vehicle. When
traffic is moving again, Traffic-
Aware Cruise Control resumes operating at
your currently set speed. However, if a
pedestrian or object is detected in front of
Model S,
Traffic-Aware Cruise Control goes
into a HOLD state and the instrument panel
displays a message indicating that you need
to resume cruise control. To resume, press the
accelerator pedal or pull the cruise control
lever toward you (see Canceling and
Resuming on page 72).
In right hand
traffic, engaging the right turn
signal when driving in the right-most lane
within 164 feet (50 meters) of an exit (on a
restricted access road only, such as a highway
or freeway), causes
Traffic-Aware Cruise
Control to assume you are exiting. As a result,
Traffic-Aware Cruise Control begins to slow
down the vehicle. Likewise in left hand traffic,when engaging the left turn signal when
driving in the left-most lane within 164 feet
(50 meters) of an exit. The onboard GPS (Global Positioning System) determines if you
are driving in a region with right or left hand
traffic. In situations where GPS data is
unavailable (for example, inadequate signal), engaging the turn signal near an exit does not
cause
Traffic-Aware Cruise Control to slow
down the vehicle.
Note: If you double-pull the cruise control
lever, Autosteer activates and the set speed
changes to your current driving speed. If you
pull and hold the lever momentarily, your set cruising speed is adjusted to either your
current driving speed, or the speed limit that
is in
effect, whichever is greater (see Cruising
at the Speed Limit on page 70).
Note: When
Traffic-Aware Cruise Control is
actively slowing down Model S to maintain the
selected distance from the vehicle ahead, the
brake lights turn on to alert other road users
that you are slowing down. You may also notice slight movement of the brake pedal.
Warning: Due to limitations inherent in
the onboard GPS, you may experience
situations in which
Traffic-Aware Cruise
Control slows down the vehicle, especially
near highway exits where a curve is
detected.
Warning: Traffic-Aware Cruise Control
can not detect all objects and may not
brake/decelerate for stationary vehicles,
especially in situations when you are
driving over 50 mph (80 km/h) and a
vehicle you are following moves out of your driving path and a stationary vehicle
or object, bicycle, or pedestrian is in front
of you instead. Always pay attention to
the road ahead and stay prepared to take
immediate corrective action. Depending
on
Traffic-Aware Cruise Control to avoid
a collision can result in serious injury or death. In addition,
Traffic-Aware Cruise
Control may react to vehicles or objects
that either do not exist or are not in the
lane of travel, causing Model S to slow down unnecessarily or inappropriately.
Warning: Traffic-Aware Cruise Control
may be unable to provide adequate
speed control because of limited braking
capability and hills. It can also misjudge the distance from a vehicle ahead. Driving
downhill can increase driving speed, causing Model S to exceed your set
speed. Never depend on
Traffic-AwareCruise Control to slow down the vehicle
enough to prevent a collision. Always
keep your eyes on the road when driving
and be prepared to take corrective action
as needed. Depending on
Traffic-AwareCruise Control to slow the vehicle down
enough to prevent a collision can result in
serious injury or death.
Warning: Traffic-Aware Cruise Control
may occasionally brake Model S when not required or you are not expecting it. Thiscan be caused by closely following a
vehicle ahead, detecting vehicles or
objects in adjacent lanes (especially on curves), etc.
Adjust your following distance
To adjust the distance you want to maintain
between Model S and a vehicle traveling ahead of you, rotate the cruise control lever to
choose a setting from 1 (the closest following distance) to 7 (the longest following distance).
Each setting corresponds to a time-based
distance that represents how long it takes for
Model S, from its current location, to reach the
location of the rear bumper of the vehicle
ahead.

Note: A horizontal line displays on the
instrument panel to represent your following distance from a vehicle ahead (see Instrument
Panel - Driving on page 46).
As you rotate the cruise control lever, the
instrument panel displays the current setting.
Release the lever when the desired setting is
displayed.
Cruising at the Speed Limit
Traffic-Aware Cruise Control makes it easy to
cruise at the speed limit. Once you

Overtake AccelerationWhen following a vehicle with
Traffic-AwareCruise Control active, engaging the turn signal
to indicate a move into the passing lane brieflyaccelerates Model S towards the vehicle
ahead. By momentarily holding the turn signal
lever up or down (depending on the region
you are driving in), you can quickly accelerate up to your set speed without having to press
the accelerator pedal. The turn signal
accelerates Model S only when the following
conditions are met:

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 cruise control is not
actively controlling your speed.
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
55).
Warning: Traffic-Aware Cruise Control
cancels, or may not be available, in the
following situations:
