10.Pay attention to alert messages that appear at the bottom center of the instrument panel. If
any alerts are in effect, you can view information about them by touching the alert icon
(exclamation mark) on the touchscreen’s status bar (the topmost area of the touchscreen).
11. Currently selected gear: Park, Reverse, Neutral, or Drive.
12. Dashed lines appear on the power meter if Model S is limiting power. The dashed lines appear
on the top portion when power available for acceleration is being limited, and on the bottom
portion when power that can be gained by regenerative braking is limited. Model S limits
power for many reasons. Here are just a few examples:
• Acceleration may be limited when the Battery is reaching a low state of charge or if the powertrain is hot.
• Both acceleration and regenerative braking may be limited when the ambient temperature is either very high or very low.
• Regenerative braking may be limited when the Battery is fully charged.

50Model S Owner's Manual

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

How It WorksThe traction control system constantly
monitors the difference in speed between 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.
On standard Model S vehicles, traction control can be turned off at any time. Turn it off only
in circumstances where you deliberately want
the wheels to spin, such as when Model S is
stuck in snow or mud.
On a dual motor Model S, you can enable slip
start to allow the wheels to spin at a limited speed. Slip start can be enabled only whenModel S is moving 20 mph (32 km/h) or
slower. Slip start automatically disables when the speed exceeds 40 mph (64 km/h).This indicator displays on the
instrument panel whenever the
traction control system is actively
controlling brake pressure and
motor power to minimize wheel spin.Warning: Traction control can not
prevent accidents caused by driving dangerously or turning too sharply at
high speeds.
Allowing Wheel Slip
Under normal conditions, the traction control
system should remain enabled. Disable it only in circumstances where you deliberately want
the wheels to spin, such as:
• Starting on a loose surface, such as gravel or snow.
• Driving in deep snow, sand or mud.
• Rocking out of a hole or deep rut.
To allow the wheels to spin on a standard single motor Model S, touch Controls >
Driving > Traction Control > Off .
To allow the wheels to spin on a dual motor
Model S, touch Controls > Driving > Traction
Control > Slip Start .
This indicator displays at the top
center of the touchscreen whenever
the wheels are allowed to spin (i.e.
when the traction control system on
a standard single-motor Model S is
turned off, or when Slip start on a
dual-motor Model S is enabled.
Although the traction control system automatically reactivates the next time you
start Model S, it is strongly recommended that you enable it immediately after thecircumstances that required you to disable it
have passed.

How Speed Assist Works
If Model S is equipped with Driver Assistance
features, a camera mounted on the windshield behind the interior rear view mirror detectsspeed limit signs. The signs are then analyzed
and compared against GPS data to determine
the speed limit at your current driving
location. For routes where no signs are present, speed limits are determined using
GPS data (if available). Instead of determining the speed limit based on signs and GPS data,you can also manually enter an arbitrary
speed limit.
When you turn on Speed Assist, the
speedometer displays a gray line to indicate
the speed limit. Warnings (described below) take effect when you exceed this limit.
In situations where the system does not have
confidence in the acquired speed limit, the speedometer displays a dashed line instead,
and warnings do not take effect. The system
may be uncertain about a speed limit if a
speed, although initially detected, is no longer known or may no longer apply. In some cases,the dashed line displays at the originallydetected speed, whereas in other cases itdisplays at 0 mph.
If you set the speed limit warning to Display
(see Controlling Speed Assist below), a speed
limit sign displays in the center of the
instrumental panel whenever you exceed the speed limit and the speedometer displays the
excess speed in gray.
Note: A speed limit sign also displays in the
center of the instrumental panel when an
automatically detected speed limit changes.
If you set the speed limit warning to Chime
(see Controlling Speed Assist) and exceed the speed limit, the speedometer displays excessspeed in gray, and you also hear a warningchime.
Note: Speed limit warnings go away
automatically after 10 seconds, or when Model
S slows down below the specified limit.
Warning: Do not rely on Speed Assist to
determine the appropriate speed limit.

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.

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.
