WipersTo wipe the windshield, rotate the end of the
left-hand steering column lever away from
you. You can choose from four levels:
• 1st: Auto with low rain sensitivity.*
• 2nd: Auto with high rain sensitivity.*
• 3rd: Continuous, slow.
• 4th: Continuous, fast.
For a single wipe, press and release the end of the lever.
If the wipers are set to Auto and the sensor
detects no water, the wipers do not wipe.
When you operate the wipers, headlights automatically turn on (if they are not onalready).
*Model S has a rain sensor located on the
inside of the windshield at the base of the interior mirror. When wipers are set to Auto,
the frequency at which they wipe depends on
how much water the sensor detects. When
wipers are set to the 2nd level, the sensor is
more sensitive.
To extend the life of wiper blades, remove ice from the windshield before turning wipers on.
Ice has sharp edges that can damage the
rubber on the blades.
Periodically check and clean the edge of the
wiper blade. If damaged, replace the blade
immediately. For details on checking and
replacing wiper blades, see Wiper Blades and
Washer Jets on page 121.
Caution:
In harsh climates, ensure that the
wiper blades are not frozen or adhered to
the windshield.De-icing Wipers
To make wiper blades easy to access so you
can remove any ice and snow, shift Model S
into Park, then use the touchscreen to move
them to the service position. Touch Controls >
Settings > Service & Reset > Service Mode >
ON . When parking in cold outdoor climates, it
is helpful to leave Model S with the wipers in
the service position. In this position, they are
closer to the defrost vent, allowing you to thaw them by directing air from the climatecontrol system towards the windshield.
Note: Wipers automatically return to their
normal position when you shift Model S out of
Park.
If Model S is equipped with the cold weather
option, you can de-ice wipers by touching Controls > Cold Weather > Heated Wipers .
The heated wipers automatically turn off after
heating the wipers for 15 minutes.
Washers
Press the button on the end of the left
steering column lever to spray washer fluid onto the windshield. You can press this buttonat two levels. Press partially for a single wipe,
without any washer fluid. Press fully for both
wipe and wash. When washing the windshield,
the wipers will perform two wipes after you
release the button, then a third wipe a few seconds later.
Periodically top up washer fluid (see Topping
Up Washer Fluid on page 125).
De-icing Washer Nozzles
If Model S is equipped with the cold weather
option, washer nozzles have de-icers that turn on whenever the ambient temperature nearsfreezing, or when you turn on the heatedwipers ( Controls > Cold Weather > Heated
Wipers ). The washer de-icers turn off when
the heated wipers turn off (after 15 minutes),
provided the temperature is warm enough to
prevent freezing.

Braking SystemsModel 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 first
start 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).
Brake Wear
Model S brake pads are equipped with wearindicators. A wear indicator is a thin metalstrip 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.
Brakes
52Model S Owner's Manual

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 your foot from the accelerator to
slow down, you can take advantage of
regenerative 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 power meter on the instrument panel displays real-time feedback on the amount of
energy being gained by regenerative braking.
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 thelevel of regenerative braking:
1. Touch Controls > Driving > Regenerative
Braking .
2. Choose from two levels:
•
Standard . Provides the maximum
amount of regenerative braking. When you release the accelerator,
Model S slows down faster, reducing
the need to use the brakes.
• Low . Limits the amount of
regenerative braking. When you
release the accelerator, Model S takes longer to slow down and coastsfurther.
Parking Brake The parking brake automatically engages
whenever you shift Model S into Park, and
releases whenever you shift into any other
gear.
Note: The parking brake operates on the rear
wheels only, and is independent of the foot-
operated brake system.
Use the touchscreen to manually release the parking brake (which also shifts Model S intoNeutral):
1. Touch Controls > E-Brake & Power Off .
2. Press the brake pedal, then touch Parking
Brake. If Model S was previously in Park, it
shifts into Neutral.
The parking brake indicator lights up on the instrument panel whenever
you use the touchscreen to manually
apply the parking brake.If an electrical issue occurs with the
parking brake, an amber parking
brake fault message displays at the
top center of the touchscreen.Caution: In the unlikely event that
Model S loses electrical power, you
cannot release the parking brake.

Driving53

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.

• 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.
