2015 TESLA MODEL S lights

Always drive at a safe speed based on
traffic and road conditions.Caution: If your Model S is equipped with
Speed Assist, you must take your vehicle to Tesla Service if a windshield
replacement is needed. Failure to do so
can cause Speed Assist to malfunction.
Controlling Speed Assist
To turn Speed Assist on or off, and control
how it works, touch Controls > Settings >
Driver Assistance > Speed Assist , then choose
one of these options:
• Off. The speed limit is not displayed.
• Display . Speed limit information visually
displays on the speedometer and when you exceed the limit, a speed limit sign
displays in the center of the instrument panel, and the speedometer displays theexcess speed in gray.
• Chime . In addition to the visual display, an
audible chime sounds whenever you
exceed the speed limit.
You can also specify how the speed limit is
determined:
• Relative . The speed limit is determined
automatically based on detected traffic
signs and GPS data. If desired, you can set
a speed limit offset (+ or -) if you want to
be alerted only when you exceed the
speed limit by a specified amount. For example, you would increase the offset to+10 mph if you only want to be alerted
when you exceed the speed limit by 10 mph.
• Absolute . Manually specify any speed limit
between 20 and 140 mph (30 and
240 km/h).
Note: GPS data is not always accurate. The
GPS can misjudge the road's location and
provide the speed limit for a directly adjacent
road that may have a different speed limit. For example, The GPS can assume Model S is on a
freeway when it’s actually on a nearby surface
street, and vice versa.
Limitations and Inaccuracies Speed Assist may not be fully functional or
may provide inaccurate information in these
situations:
• Visibility is poor and speed limit signs 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.).
• Speed limit signs are concealed by objects.
• The speed limits stored in the GPS database are incorrect or outdated.
• Model S is being driven in an area where GPS data is not available.
• Traffic signs do not conform to standard recognizable formats.
• A road or a speed limit has recently changed.

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.
Lane Departure Warning

• 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.).Warning: The list above does not
represent an exhaustive list of situations
that may interfere with proper operation of Forward Collision Warning. ForwardCollision Warning may fail to provide
warnings for many other reasons. To
avoid a collision, stay alert and always pay attention to the area in front of
Model S so you can anticipate the need to take corrective action as early as
possible.
Forward Collision Warning
Driving59

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.

Changing the Set Speed
To change the set speed while using Traffic-
Aware Cruise Control, move the cruise control
lever up (increase) or down (decrease) until your desired speed is reached.
Move the lever up or down to the first position
and release to increase/decrease speed by 1 mph (1 km/h). Move the lever up/down to
the second position and release to increase/ decrease speed to the next multiple of 5 mph
(5 km/h). For example, if you are travelling at 54 mph (86 km/h) and move the lever up to
the second position and release, the speed increases to 55 mph (90 km/h).
You can also hold the lever up or down to
increase/decrease the speed in 2 mph (2 km/h) increments, then release when youreach the desired speed.
Note: It may take a few seconds for Model S
to reach the new cruising speed.

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.
