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.

60Model S Owner's Manual

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

Cleaning the Exterior
To prevent damage to the paint, immediately
remove corrosive substances (bird droppings, tree resin, dead insects, tar spots, road salt,industrial fallout, etc). Do not wait untilModel S is due for a complete wash. If
necessary, use denatured alcohol to remove
tar spots and stubborn grease stains, then
immediately wash the area with water and a
mild, non-detergent soap to remove the
alcohol.
Follow these steps when washing the exterior of Model S:
1. Rinse Thoroughly
Before washing, flush grime and grit from
the bodywork using a hose. Flush away accumulations of mud in areas where
debris easily collects (such as wheel arches and panel seams). If salt has beenused on the highways (such as duringwinter months), thoroughly rinse all tracesof road salt from the underside of the
vehicle.
2. Hand Wash
Hand wash Model S using a soft cloth and cold or lukewarm water containing a mild,
good quality car shampoo.
3. Rinse with Clean Water
After washing, rinse with clean water to
prevent soap from drying on the surfaces.
4. Dry Thoroughly and Clean Exterior Glass
After washing and rinsing, dry thoroughly with a chamois.
Clean windows and mirrors using an
automotive glass cleaner. Do not scrape,
or use any abrasive cleaning fluid on glass
or mirrored surfaces.Cautions for Exterior CleaningCaution: Do not use windshield treatment
fluids. Doing so can interfere with wiper
friction and cause a chattering sound.Caution: Do not use hot water and
detergents.Caution: In hot weather, do not wash in
direct sunlight.Caution: If using a pressure washer,
maintain a distance of at least 12" (30 cm) between the nozzle and the surface ofModel S. Keep the nozzle moving and do
not concentrate the water jet on any one area.Caution: Do not aim water hoses directly
at window, door or hood seals, or through wheel apertures onto brake components.Caution: Avoid using tight-napped or
rough cloths, such as washing mitts.Caution: If washing in an automatic car
wash, use Touchless car washes only. These car washes have no parts (brushes,etc.) that touch the surfaces of Model S.Using any other type of car wash could
cause damage that is not covered by the warranty.Caution: Do not used chemical based
wheel cleaners. These can damage the finish on the wheels.Caution: Avoid using a high pressure
power washer on the rear view camera or
parking sensors (if equipped) and do not
clean a sensor or camera lens with a
sharp or abrasive object that can scratch
or damage its surface.
