TESLA MODEL S 2017 Workshop Manual

5. Exterior lights (headlights, tail lights, side marker lights, parking lights, and license platelights) are set to AUTO each time you start Model S.
AUTOExterior lights automatically turn on when driving in low lighting
conditions. If you change to a different setting, lights always revert to this
AUTO setting on your next drive.
Touch one of these options to temporarily change the exterior light setting:
OFF
Exterior lights turn off until you manually turn them back on
or until the next time you drive Model S. If daytime running
lights are required in your region, the exterior lights used for
this purpose do not turn
off.
PARKINGOnly the side marker lights, parking lights, tail lights and
license plate lights turn on.ONExterior lights turn on.
Note: Model S has a series of lights along the lower rim of the headlights, also referred to as "signature" lights. These lights automatically turn on whenever Model S is powered on and a driving gear is engaged. In the U.S. only, these lights turn
off to conserve energy when you
turn the Range mode setting on (see Controls on page 95 or Driving Tips to Maximize
Range on page 62).
Warning: Always ensure that your headlamps are switched to AUTO or ON, as
appropriate, during all low visibility conditions. Failure to do so may result in a collision.

High Beam HeadlightsPush the left-hand steering column lever away
from you. To cancel, pull the lever toward you.
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 high
beam headlights can automatically switch to low beam when there is light detected in front
of Model S (for example, from an oncoming vehicle or street lights). To turn this feature on,touch Controls > Auto High Beam.
Note: Your chosen setting is retained until you manually change it. It can also be saved in
your driver
profile.
In situations where high beams are turned offbecause Auto High Beam is turned on and
light is detected in front of Model S, you can
temporarily turn on high beams by pulling the
lever all the way toward you.
The following indicator light islights are visible
on the instrument panel when high beams are
turned on:
High beams are turned on.High beams are turned on and the
Auto High Beam setting is turned
off.
High beams are currently turned on,
and Auto High Beam is ready to turn
off the high beams if light is
detected in front of Model S.
High beams are temporarily turnedoff because Auto High Beam is on
and is detecting light in front of
Model S. When light is no longer
detected, the high beams will
automatically turn back on.
To flash the headlight high beams, pull the
lever fully toward you and release.
Warning: Auto High Beam is an aid only and is subject to limitations. It is the

Turn Signals
Move the left-hand steering column lever up
(before turning right) or down (before turning
left).
The turn signals stop operating when canceled by the steering wheel, or when you return the
lever to the central position.
The corresponding turn signal
indicator lights up on the instrument
panel when a turn signal is
operating. You also hear a clicking
sound.Warning: If Model S is equipped with both
Autopilot hardware and the optional
Autopilot Tech Package, and
Traffic-
Aware Cruise Control is active, engaging
a turn signal can cause Model S to accelerate when using
Traffic-AwareCruise Control in specific situations (see
Overtake Acceleration on page 70).
Warning: If Model S is equipped with both
Autopilot hardware and the optional
Autopilot Tech Package, and Autosteer is active, engaging a turn signal can cause
Model S to change lanes (see Auto Lane
Change on page 76).
Lane Change Flash
To indicate a lane change, quickly press the
lever up or down against the spring pressure,
then release. The corresponding turn signal
flashes three times.
Hazard Warning Flashers To turn on the hazard warning
flashers, press
the button located on the side of the
touchscreen closest to the steering wheel. All
turn signals
flash. Press again to turn off.
Note: Hazard warning flashers operate even
without a Model S key nearby.

Wipers
To wipe the windshield, rotate the end of the
left-hand steering column lever away from
you. You can choose from four levels:

Braking Systems
Model S has an anti-lock braking system
(ABS) that prevents the wheels from locking when you apply maximum brake pressure. This
improves steering control during heavy
braking in most road conditions.
During emergency braking conditions, the
ABS constantly monitors the speed of each
wheel and varies the brake pressure according to the grip available.
The alteration of brake pressure can be felt as
a pulsing sensation through the brake pedal.
This demonstrates that the ABS is operating
and is not a cause for concern. Keep
firm and
steady pressure on the brake pedal while
experiencing the pulsing.
The ABS indicator flashes briefly on
the instrument panel when you firststart Model S. If this indicator lights
up at any other time, an ABS fault
has occurred and the ABS is not
operating. Contact Tesla. The braking system remains fully operational and
is not
affected by an ABS failure.
However, braking distances may increase.
If the instrument panel displays this
indicator at any time other than
displaying
briefly when you first start
Model S, a brake system fault is
detected or the brake
fluid level is
low. Contact Tesla immediately.
Emergency Braking
In an emergency, fully press the brake pedal and maintain
firm pressure, even on low
traction surfaces. The ABS varies the braking
pressure to each wheel according to the
amount of traction available. This prevents
wheels from locking and ensures that you stop
as safely as possible.
Warning: Do not pump the brake pedal.
Doing so interrupts operation of the ABS
and can increase braking distance.Warning: Always maintain a safe distance
from the vehicle in front of you and be
aware of hazardous driving conditions.
While the ABS can improve stopping
distance, it cannot overcome the laws of physics. It also does not prevent the
danger of hydroplaning (where a layer of
water prevents direct contact between the tires and the road).
If Model S is equipped with Autopilot
hardware, Automatic Emergency Braking
automatically applies full braking in situations
where a collision is considered imminent (see
Automatic Emergency Braking on page 86).
Brake Wear Model S brake pads are equipped with wear
indicators. A wear indicator is a thin metal
strip attached to the brake pad that squeals as it rubs against the rotor when the pad wears
down. This squealing sound indicates that the
brake pads have reached the end of their
service life and require replacement. To stop
the squealing, contact Tesla Service.
Warning: Neglecting to replace worn
brake pads results in damage to the
braking system and can create a braking
hazard.

Regenerative Braking
Whenever Model S is moving and your foot is
off the accelerator, regenerative braking slows
down Model S and feeds any surplus energy
back to the Battery.
By anticipating your stops and simply
removing pressure from the accelerator to slow down, you can take advantage ofregenerative braking to increase driving range.
Of course, this is no substitute for regular
braking when needed for safety.
Note: If regenerative braking is aggressively
slowing Model S, such as on a steep descent,
brake lights turn on to alert other road users
that you are slowing down.
The Energy app displays real-time feedback
on the amount of energy being gained by
regenerative braking. You can also display the
power meter on either side of the instrument
panel by choosing Energy using the scroll
button on the steering wheel (see Steering
Wheel on page 37).
The amount of energy fed back to the Battery using regenerative braking can depend on the
current state of the Battery and the charge
level setting that you are using. If regenerative
braking is limited, a dashed yellow line
displays on the power meter. For example,
regenerative braking may be limited if the Battery is already fully charged or if the
ambient temperature is low.
To Set the Regenerative Braking Level
You can use the touchscreen to change the
level of regenerative braking:
1. Touch Controls > Driving > Regenerative Braking.
2. Choose from two levels:

How It WorksThe traction control system constantly
monitors the speed of the front and rear
wheels. If Model S experiences a loss of
traction, the system minimizes wheel spin by
controlling brake pressure and motor power.
By default, the traction control system is
always active. Under normal conditions, it should remain active to ensure maximum
safety.This indicator flashes on the
instrument panel whenever the
traction control system is actively
controlling brake pressure and motor
power to minimize wheel spin. If the
indicator stays on, a fault is detected with the traction control system.
Contact Tesla Service.Warning: Traction control cannot prevent
accidents caused by driving dangerously
or turning too sharply at high speeds.Warning: If the above indicator remains
illuminated in situations in which you have
not enabled Slip Start (described next), the traction control system may not be
operating correctly. Contact Tesla Service immediately.
Allowing Wheel Slip
To allow the wheels to spin at a limited speed,
you can enable Slip Start. Slip Start can be
enabled only when Model S is moving 30 mph
(48 km/h) or slower. Slip Start automatically
disables when the speed exceeds 50 mph
(80 km/h).
Under normal conditions, Slip Start should not
be enabled. Enable it only in circumstances where you deliberately want the wheels tospin, such as:

How Park Assist Works
Model S has several sensors designed to detect the presence of objects nearby. When
moving slowly in Drive or Reverse, the sensors
alert you if an object is detected in close proximity to the front and rear of your
Model S.
Note: Depending on date of manufacture and options selected at time of purchase, someModel S vehicles are not equipped with theparking sensors.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, causingeither no readings or false readings (see
Limitations and False Warnings on page
58). Therefore, depending on Park Assist
to determine if Model S is approaching an obstruction can result in damage 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 Assist
view 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 64).
You can manually close the park assist view on
the touchscreen 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 appwindow. This is useful if you need assistance
with parallel parking.
If chimes are turned on (see Controlling
Audible Feedback on page 58), 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 Model S 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
Park Assist
Driving57

the camera app window. You must be drivingat speeds below 5 mph (8 km/h).
Note: If a sensor is unable to provide
feedback, the instrument panel displays an
alert message.Caution: Keep sensors clean from dirt,
debris, snow, and ice. Avoid using a high
pressure power washer on the sensors
and do not clean a sensor with a sharp or abrasive object that can scratch or
damage its surface.Caution: Do not install accessories or
stickers on or near the parking sensors.
Controlling Audible Feedback
You can use Park Assist with or without
audible feedback. To turn chimes on or
off,touch Controls > Settings > Safety &
Security > Park Assist Chimes.
You can also mute the chimes temporarily by
pressing the scroll wheel on the left side of the steering wheel or by touching the mute buttonin the bottom left corner of the Park Assist
view. The chimes are muted until you shift into
a
different gear or drive over 5 mph (8 km/h).
Limitations and False Warnings
The parking sensors may not function
correctly in these situations:

When Model S is stopped, Vehicle Holdcontinues to apply the brakes even after you
remove your foot from the brake pedal. When
driving on a hill or on a
flat surface, brake as
you normally would. You can release the brake
pedal, and remain stopped (even on a hill),
whenever the instrument panel displays the
Vehicle Hold indicator light.
This indicator displays on the
instrument panel whenever Vehicle
Hold is engaged.
To disengage Vehicle Hold, press the
accelerator pedal or press and release the
brake pedal.
Note: Shifting into Neutral also disengages Vehicle Hold.
Note: After actively braking Model S for
approximately 10 minutes, Model S shifts into
Park and Vehicle Hold cancels. Model S also shifts into Park if it detects that the driver has
left the vehicle.
