How Lane Departure Warning
Works
If Model S is equipped with Autopilot, a
camera mounted on the windshield behind the interior rear view mirror monitors the markers
on the lane you are driving in. If a front wheel passes over a lane marking and the associated
turn signal is off, you feel three slight
vibrations in the steering wheel.
Lane Departure Warning operates only when
Model S is traveling over approximately
30 mph (50 km/h).Warning: Lane Departure Warning is for
guidance purposes only. Never depend
on Lane Departure Warning to inform you of unintentionally driving outside of theboundaries of the driving lane. Several
external factors can reduce the
performance of Lane Departure Warning,
causing either no readings or false
readings. Therefore, depending on this
system to stay within the boundaries of the driving lane can result in serious injuryor death. Always keep your eyes on the
road when driving. It is the driver's
responsibility to stay alert, drive safely,
ensure the vehicle stays in the traveling lane, and be in control of the vehicle at all
times.Warning: Lane Departure Warning is
designed to activate when it detects lane markings. It is not designed to detect the
edge of a road. It is the driver's
responsibility to drive attentively and stay
within the boundaries of the driving lane.Caution: If your Model S is equipped with
Lane Departure Warning, you must take
your vehicle to Tesla Service if a
windshield replacement is needed. Failure
to do so can cause Lane Departure
Warning to malfunction.Controlling Lane Departure
Warning
To turn Lane Departure Warning on or off,
touch Controls > Settings > Driver
Assistance > Lane Assist .
Limitations and Inaccuracies Lane Departure Warning can not always
clearly detect lane markings and you may
experience unnecessary or invalid warnings in
these situations:
• Visibility is poor and lane markings are not clearly visible (due to heavy rain, snow,fog, etc.).
• Bright light (oncoming headlights or direct sunlight) is interfering with thecamera's view.
• Model S is being driven very close to a vehicle in front of it which is blocking the
camera's view.
• The windshield area in the camera's field of view is obstructed (fogged over, dirty,
covered by a sticker, etc.).
• Lane markings are excessively worn or have been adjusted due to roadconstruction.
• Lane markings are changing quickly (for example, lanes branching off, crossing
over, or merging).
• The road is narrow or winding.
• Objects or landscape features are casting strong shadows on lane markers.

How Forward Collision Warning
Works
If Model S is equipped with Autopilot, a
camera mounted on the windshield behind the interior rear view mirror and a radar sensor in
the center of the front grill monitor the area in
front of Model S for the presence of a vehicle,
bike or pedestrian. If a collision is considered likely unless you take immediate correctiveaction, Forward Collision Warning is designedto provide visual and audible warnings.
The cameras and sensors associated withForward Collision Warning are designed to
monitor an approximate area of up to 525 feet (160 meters) in the driving path, as illustrated
below.Warning: The area being monitored by
Forward Collision Warning can be adversely affected by road and weatherconditions (see Limitations on page 58).
Use appropriate caution when driving.Caution: If your Model S is equipped with
Forward Collision Warning, you must take
your vehicle to Tesla Service if a
windshield replacement is needed. Failure
to do so can cause Forward Collision
Warning to malfunction.Warning: Forward Collision Warning does
not operate when Model S is traveling less than 4 mph (7 km/h).Warning: Forward Collision Warning is
designed only to provide visual and
audible alerts (see Visual and Audible
Feedback on page 58). It does not
attempt to apply the brakes or decelerate
Model S. When seeing and/or hearing a warning (described below), it is the
driver's responsibility to immediately take an appropriate action.Warning: Forward Collision Warning is for
guidance purposes only and is not a
substitute for attentive driving and soundjudgement. Always keep your eyes on the road when driving and never depend on
Forward Collision Warning to warn you of a potential collision. Several factors canreduce the performance of Forward
Collision Warning, causing either
unnecessary, invalid, inaccurate, or
missed warnings (see Limitations on page
58). Depending on Forward Collision
Warning to warn you of a potential
collision can result in serious injury or
death.
Visual and Audible Feedback
When a collision with a vehicle, bicycle, or
pedestrian is considered likely unless
immediate action is taken, Forward Collision
Warning is designed to sound an audible alert
and display a collision warning in the center of the instrument panel.
Warnings cancel automatically when the risk
of a collision has been reduced (for example,
you have decelerated or stopped Model S, or
a vehicle in front has moved out of your
driving path).
Warning: Forward Collision Warning may
provide a warning in situations where the
likelihood of collision may not exist. Stay
alert and always pay attention to the area
in front of Model S so you can anticipate
whether any action is required.
Controlling Forward Collision
Warning
To turn Forward Collision Warning off or
adjust its sensitivity, touch Controls >
Settings > Driver Assistance > Forward
Collision Warning . Instead of the default
warning level of Medium, you can turn the
warning Off, or you can choose to be warned
Late or Early .
Note: Your chosen setting is retained until you
manually change it. It can also be saved in
your driver profile.
Limitations Forward Collision Warning cannot always
detect vehicles, bikes, or pedestrians, and you may experience unnecessary, inaccurate,
invalid or missed warnings for many reasons, particularly if:
• The road has sharp curves.

58Model S Owner's Manual

Traffic-Aware Cruise Control uses a camera
mounted on the windshield behind the interior
rear view mirror and a radar sensor in the
center of the front grill to detect whether
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 is designed todrive consistently at a set speed. When a
vehicle is detected, Traffic-Aware Cruise
Control is designed to slow down Model S if needed to maintain a selected time-baseddistance 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 if needed.
Traffic-Aware Cruise Control makes it easy to maintain a consistent time-based distance
from a vehicle travelling in front of you in the
same lane. 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.
Note: Traffic-Aware Cruise Control is available
only if your Model S is equipped with Autopilot hardware and you have purchased
the Tech Package.
Operating Traffic Aware Cruise
Control
1. Touch the end of the cruise control lever.
Unless a vehicle is detected ahead of you, you must be driving at least 18 mph
(30 km/h) to initiate Traffic-Aware Cruise
Control. If a vehicle is detected in front of you, you can initiate Traffic-Aware CruiseControl at any speed, even when
stationary.
The light on the lever turns on. Traffic-
Aware Cruise Control is now in standby
mode and is not actively controlling your speed until you specify a cruising speed,
as described in the next step.
2. Set your cruising speed by accelerating
until you reach a desired cruising speed
then moving the cruise control lever up or
down (or pull briefly toward you), then
releasing.
Once you've initally set a cruising speed, you can adjust the speed to cruise at the
speed limit that is currently being
determined by Speed Assist (see Speed
Assist on page 55). To do so, pull the
cruise control lever toward you and hold momentarily (about half a second). Whenyou release, your cruising speed is set to
the speed that is automatically or manually being determined by Speed
Assist, taking into consideration any offset you may have specified.
Note: When you adjust the cruising speed
based on the speed limit, the set speed
does not change when the speed limit changes. You will need to pull the lever
again. You can also manually adjust your
cruising speed at any time (see Changing
the Set Speed on page 62).
Warning: Do not rely on Speed Assist
to determine an accurate or
appropriate cruising speed. Always
cruise at a safe speed based on traffic and road conditions.
3. To set the distance you want to maintain
between Model S and a vehicle travelling
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.
As you rotate the cruise control lever, the
instrument panel displays the current
setting. Release the lever when the
desired setting is displayed.
Traffic-Aware Cruise Control
60Model S Owner's Manual

The instrument panel displays the Cruisemessage above the speedometer (see
Instrument Panel Indicator Lights on page
62) and a tick mark at the edge of the
speedometer indicates the set speed.
You can now release the accelerator pedal
and allow Traffic-Aware Cruise Control to maintain your set speed. When no vehicle isdetected 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, 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.
You can accelerate at any time when driving at a 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. If
Model S comes to a standstill and remains stationary for approximately three seconds
(slightly longer when driving on highway
conditions), you will need to resume Traffic-
Aware Cruise Control by pressing the
accelerator pedal or pulling the cruise control lever toward you (see Canceling and
Resuming on page 64). A message displays
on the instrument panel that you need to
resume Traffic-Aware Cruise Control.
When Traffic-Aware Cruise Control is actively
slowing down Model S to maintain the
selected distance from the vehicle ahead,
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: Do not depend on Traffic-
Aware Cruise Control to adequately and appropriately slow down Model S. Always
watch the road in front of you and stay
prepared to brake at all times. Traffic-
Aware Cruise Control does not eliminate the need to apply the brakes as needed,even at slow speeds.Warning: Traffic-Aware Cruise Control
can not detect all objects and may not
detect a stationary vehicle or other objectin the lane of travel. There may be
situations in which Traffic-Aware Cruise
Control does not detect a vehicle, bicycle, or pedestrian. Depending on Traffic-
Aware Cruise Control to avoid a collision can result in serious injury or death.Warning: 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 misjudge the distance from a vehicle ahead. Always watch the road in front of
you. It is the driver's responsibility to
maintain a safe distance from a vehicle
ahead of you.Warning: When you enable Traffic-Aware
Cruise Control in a situation where you are closely following the vehicle in front
of you, Model S may apply the brakes to
maintain the selected distance.Warning: Traffic-Aware Cruise Control
has limited deceleration ability and may be unable to apply enough braking to
avoid a collision if a vehicle in front slows
suddenly, or if a vehicle enters your driving lane in front of you. Never dependon Traffic-Aware Cruise Control to slowdown 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-Aware Cruise
Control to slow the vehicle down enough
to prevent a collision can result in serious
injury or death.Warning: Driving downhill can increase
driving speed, causing Model S to exceed
your set speed. Hills can also make it
more difficult for Model S to slow down
enough to maintain the chosen following
distance from the vehicle ahead.Warning: Traffic-Aware Cruise Control
may occasionally brake Model S when not required based on the distance from a
vehicle ahead. This can be caused by vehicles in adjacent lanes (especially on
curves), or by stationary objects.

Driving61

Overtake AccelerationWhen following a vehicle with Traffic-AwareCruise Control operating, engaging the turnsignal to indicate a move into the passing lanebriefly accelerates Model S towards thevehicle ahead. By engaging or momentarilyholding the turn signal, you can quicklyaccelerate 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:
• Traffic-Aware Cruise Control is operating and detecting a vehicle in front.
• Model S is travelling below the set speed, but over 45 mph (72 km/h).
• The turn signal indicates a move into the passing lane.
• The Overtake Acceleration setting is turned ON ( Controls > Settings > Driver
Assistance > Overtake Acceleration ).
Overtake Acceleration is intended as an aid
when passing a vehicle ahead of you. When
the turn signal is engaged, Traffic Aware
Cruise Control continues to maintain distance
from the vehicle ahead, but allows you to
drive slightly closer than your selected
distance.
Acceleration cancels when:
• You reach your set cruising speed.
• Changing lanes takes too long.
• Model S gets too close to the vehicle ahead.
OR
• You disengage the turn signal.
To turn Overtake Acceleration on or off, touch
Controls > Settings > Driver Assistance >
Overtake Acceleration . When Overtake
Acceleration is turned off, engaging a turn
signal when Traffic-Aware Cruise Control is
active does not increase your driving speed.
Note: Overtake Acceleration occurs when you
either fully engage the turn signal, or you hold the turn signal in the momentary position(partially engaged). When you release ordisengage the turn signal, Model S stops
accelerating (in the same way as when you
release the accelerator pedal) and resumes
the set speed.Note: Model S automatically determines
whether the turn signal indicates a move into a passing lane based on if you are driving in aregion with right or left hand traffic. Whendriving in right hand traffic, only the left turn
signal (moving the turn signal lever down) provides acceleration. In left hand traffic, only
the right turn signal (moving the turn signal
lever up) provides acceleration.Warning: Overtake acceleration can
cancel for many unforeseen reasons in
addition to those listed above. Stay alert and never depend on Overtake
Acceleration to increase your driving
speed.Warning: Overtake Acceleration increases
your driving speed whenever the
appropriate turn signal is engaged, even
when it may not be your intention to
overtake the vehicle you are following.
Although Traffic-Aware Cruise Control
maintains a safe driving distance from the
vehicle ahead, it is the driver's
responsibility to drive safely and stay in
control of the vehicle at all times.Warning: Model S uses its onboard GPS
(Global Positioning System) to determine
if you are currently driving in a region
with right hand or left hand traffic. GPS
data is not always accurate and may not
always be available. It is the driver's
responsibility to stay in control of the
vehicle at all times. Never depend on
Overtake Acceleration to appropriately
increase your driving speed. Conversely,
when using Traffic-Aware Cruise Control,
never assume that using a turn signal will
not increase your driving speed.
Depending on this feature can result in
serious injury or death.
Traffic-Aware Cruise Control
Driving63

Canceling and Resuming
To manually cancel Traffic-Aware Cruise
Control, briefly push the cruise control lever
away from you. The message on the
instrument panel turns off, but the set speed remains displayed until Model S powers off.
To resume cruising at the previously set
speed, briefly pull the cruise control lever
toward you.
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 off
the accelerator when driving without cruise
control (see Regenerative Braking on page
53).
Warning: Traffic-Aware Cruise Control
may immediately cancel, or may not be available, in the following situations:
• You press the brake pedal.
• Your driving speed drops below 18 mph (30 km/h) in situations when
Model S does not detect a vehicle
ahead within the specified distance.
• You shift Model S out of Drive.
• The driver's seat belt is unbuckled.
• A door is opened.
• The view from the radar sensor or camera is obstructed. This could be
caused by dirt, mud, ice, snow, fog,
etc.
• The traction control setting is manually disabled or is repeatedly
engaging to prevent wheels from
slipping.
• The wheels are spinning while at a standstill.• The cruise control system is failing
and requires service.
When Traffic-Aware Cruise Control is unavailable or cancels, all cruise control
functionality is unavailable. Model S no longer drives consistently at a set speed
and no longer maintains a specified
distance from the vehicle ahead.Warning: Traffic-Aware Cruise Control
can cancel unexpectedly at any time for
unforeseen reasons. Always watch the
road in front of you and stay prepared to
take appropriate action. It is the driver's responsibility to be in control of Model S
at all times.
Limitations
Traffic-Aware Cruise Control is particularly
unlikely to operate as intended in the
following types of situations:
• The road has sharp curves.
• Visibility is poor (due to heavy rain, snow, fog, etc.).
• Bright light (oncoming headlights or direct sunlight) is interfering with the
camera's view.
• The radar sensor in the center of the front grill is obstructed (dirty, covered, etc.).
• The windshield area in the camera's field of view is obstructed (fogged over, dirty,
covered by a sticker, etc.).
Caution: If your Model S is equipped with
Traffic-Aware Cruise Control, you must take your vehicle to Tesla Service if a
windshield replacement is needed. Failure
to do so can cause Traffic-Aware Cruise
Control to malfunction.Warning: Many unforeseen circumstances
can impair the operation of Traffic-Aware Cruise Control. Always keep this in mind
and remember that as a result, Traffic-
Aware Cruise Control may not slow down or may brake or accelerate Model S
inappropriately. Always drive attentively and be prepared to take immediate
action.Warning: Traffic-aware cruise control
may not brake/decelerate for stationary vehicles, especially in situations when youare driving over 50 mph (80 km/h) and a
vehicle you are following moves out of your driving path and a stationary vehicleor object is in front of you instead.
Always pay attention to the road ahead
and stay prepared to take immediate

How Park Assist Works
If Model S is equipped with the Park Assist option, Model S has several sensors designedto detect the presence of objects nearby.When moving slowly in Drive or Reverse, the
sensors alert you if an object is detected close to the front or rear bumper, respectively.Warning: The Park Assist images
provided below are representative only.
The exact number and location of sensors
may vary depending on the date your
Model S was manufactured.
The sensors are activated when driving less
than 5 mph (8 km/h).
Warning: Never depend on Park Assist to
inform you if an area you are approaching is free of objects and/or people. Several
external factors can reduce the
performance of Park Assist, causing
either no readings or false readings (see Limitations and False Warnings on page
67). Therefore, depending on Park Assist to determine if Model S is
approaching an obstruction can result indamage to the vehicle and/or objects,
and can potentially cause serious injury.
Always inspect the area with your own
eyes. When reversing, perform shoulder
checks and use all mirrors. Park assist
does not detect children, pedestrians,
bicyclists, animals, or objects that are moving, protruding, located too far above
or below the sensors, or too close or too far from the sensors. Park Assist is for
guidance purposes only and is not
intended to replace your own direct
visual checks. It is not a substitute for careful driving.
Visual and Audio Feedback
When you shift to Reverse, the Park Assistview displays on the left side of the
instrument panel, showing any objects that
are in close proximity to the front and rear of
Model S. This view closes when you shift into
Drive unless objects are detected close to the front of the Model S, in which case the Park
Assist view closes automatically when your
driving speed exceeds 5 mph (8 km/h) . When reversing, visual feedback also displays on the
touchscreen, immediately below the camera
view (see Rear View Camera on page 71).
You can close this view manually by touching
the X in the upper left corner.
When driving with the Camera app displayed
on the touchscreen, you can switch to the Park Assist view when driving at speeds
below 5 mph (8 km/h) . Touch the button
located in the upper left corner of the Camera
app window. This is useful if you need
assistance with parallel parking.
If chimes are turned on (see Controlling
Audible Feedback on page 67), an audible
beep sounds as you approach an object. You
can temporarily mute the chime by pressing
the scroll wheel on the left side of the steering
wheel or by touching the mute button located
on the in the bottom left corner of the Park Assist view.
Note: If your vehicle is equipped with software
version 6.1 or newer, and you are driving with the camera app displayed on the touchscreen,
you can switch to the Park Assist view by
touching the icon in the upper left corner of the camera app window. You must be driving
at speeds below 5 mph (8 km/h) .
Note: If a sensor is unable to provide
feedback, the instrument panel displays an
alert message.

Driving Tips to Maximize RangeYou can maximize your driving range usingthe same driving habits that you use to
conserve fuel in a gasoline-powered vehicle. In
addition to driving habits, energy
consumption depends on environmental conditions (such as cold weather and hillyroads). To get the maximum mileage from a
charge:
• Avoid frequent and rapid acceleration. • Instead of using the brake to slow down, move your foot off the accelerator.
Whenever Model S is moving and your
foot is off the accelerator, regenerative
braking slows down Model S and feeds
surplus energy back to the Battery (see
Regenerative Braking on page 53).
• Keep tires at the recommended inflation pressures (see Tire Care and Maintenance
on page 109).
• Lighten your load by removing any unnecessary cargo.
• Limit the use of resources such as heating and air conditioning. Using seat heaters to
keep warm is more efficient than heating the cabin. To automatically limit the
amount of power that the climate control system uses to maintain the temperatureof the Battery and the cabin area, touch
Controls > Driving > Range Mode > ON .
Note: On Dual Motor vehicles, you can turn on
Range Mode only when acceleration is set to Sport (if you change Acceleration to Insane,Range Mode automatically turns off).
The power meter on the instrument panel and
the Energy app (described next) provide
feedback on energy usage. With this
feedback, you will soon become familiar with how driving habits and environmental
conditions impact how much energy Model S
is using.
Energy App Use the energy app to view real-time and
projected energy usage. Choose from two
types of charts:
• Consumption Chart: - display how much energy Model S has consumed over thepast 5, 15 or 30 miles (10, 25 or 50 kms).
• Trip Chart - If your Model S is equipped with the navigation option, you can trackthe amount of energy being consumed
while navigating to a destination. The gray
line represents predicted usage and the
green line represents actual usage. Touchthe zoom icon in the top right corner to change the zoom level.
Note: The Trip Chart displays energy usage
only if you are currently navigating to a destination.
Note: In some situations, values and distances
on the Trip chart may be inaccurate. For example, when charging Model S during anactive navigation route. To resolve
inaccuracies, cancel and reinitiate navigation to the destination.
Saving Energy Model S has an energy-saving feature that
reduces the amount of energy being
consumed when Model S is not in use. Touch Controls > Displays > Energy Saving and
choose from the following options:
• OFF . All display systems remain powered
when Model S is not in use, providing the most responsive experience. More energy
is consumed.
• NIGHTLY . Model S shifts to the energy-
saving mode at night (10 pm to 5 am).
• ON. Significantly less energy is consumed
whenever Model S is not in use. The start-
up time of the instrument panel and
Bluetooth could be slower.
• Always Connected . Preserves cell
connectivity when energy saving is active.
This allows the mobile app to connect to
Model S more quickly, and provides
immediate 3G internet access when entering the car. Slightly more energy isconsumed.
