2015 TESLA MODEL S warning lights

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
Driving57

• 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.
Traffic-Aware Cruise Control
Driving61

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

About HomeLinkIf Model S is equipped with the optional tech
package, you can program the HomeLink ®
Universal Transceiver to operate up to three
garage doors, gates, lights, and security
systems that can transmit Radio Frequency
(RF) signals.
Programming HomeLink
1. Park Model S in front of the device you
want to program, and have the device’s
remote control ready.
2. Touch Controls > Settings > HomeLink on
the touchscreen.
3. Touch Add New HomeLink , then use the
onscreen keyboard to enter a name for
your HomeLink device.
4. Touch Program .
5. Follow the onscreen instructions.
Once programmed, you can operate the device by touching its corresponding
HomeLink icon on the touchscreen’s status bar. HomeLink remembers the location of
your programmed devices. When you approach a known location, the HomeLink
control on the touchscreen automatically
drops down. When you drive away, it
disappears.
Note: For security reasons, erase your
HomeLink settings if you sell Model S.Warning: Your device might open or
close during programming. Before
programming, make sure that the device is clear of any people or objects.Warning: Do not use the HomeLink
Universal Transceiver with a garage door that does not meet safety standards. Agarage door opener that cannot detectan object in its path and then
automatically stop and reverse, does not
meet these standards. Using a garage
door opener without these features
increases the risk of injury or death.
Troubleshooting HomeLink
When programming a HomeLink device, the touchscreen steps you through a two-part
programming process:
• First, Model S records the signal from the remote. The touchscreen instructs you to
stand in front of the car, point the remote
at the front bumper and press and hold
the button until the headlights flash.
When headlights flash, Model S has
learned the remote and you can touch
Continue on the touchscreen . If the
headlights do not flash, refer to the
guidelines below.
• Next, the device's receiver learns Model S. The touchscreen instructs you to press
the LEARN button on the garage door or
gate's receiver. If training the receiver
does not work, refer to the guidelines
below.
NOTE: Only devices that are equipped
with a “rolling code” remote need to learn
Model S. If you have a very old device that
is not equipped with a rolling code
remote, the device does not need to learn
Model S and you can skip this part. You
can also skip this step if your receiver is
Quick-Train compatible. The opener
should work.
Headlights do not flash
• Check the batteries in the remote. It is a good idea to replace the batteries before
you start programming.
• Hold the remote against the nose cone, with the button pressed, about 6 inches to
the left of the Tesla emblem. In some
cases you must hold the remote for up to
three minutes.
• Check compatibility of the remote by contacting the HomeLink manufacturer
( www.homelink.com ).
After programming, the device does not work
• Park Model S with its front bumper as close as possible to the HomeLink device
(garage door, gate, etc).
• Make sure you haven’t reached the device receiver's limit of learned remotes/cars.
Most receivers can learn up to five
remotes/cars. If the receiver's memory is
full, you must clear the memory and
restart the programming process. For
instructions on how to clear the receiver's
memory, refer to the owner
documentation provided with the
HomeLink device.
• Make sure you are pressing the receiver's LEARN button. Most receivers have twobuttons and a LED. One button is a RESET
button and the other is a LEARN button.
Pressing the LEARN button usually causes the LED to flash. For instructions on how
to put the receiver into learning mode, refer to the owner documentation
provided with the HomeLink device.
