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.
13. Date and time

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 assistance level 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 assistance level to Chime (see
Controlling Speed Assist) and exceed the
speed limit, the speedometer displays excess
speed in gray, and you also hear a warning
chime.
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 Driver Assistance
features, 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: Never depend on Lane
Departure Warning to inform you of
unintentionally driving outside of the
boundaries 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 injury
or death. Lane Departure Warning is for
guidance purposes only. 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.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 Assist on or off, touch Controls >
Settings > Driver Assistance > Lane Departure
Warning .
Limitations and Inaccuracies
Lane Departure Warning can not always
clearly detect lane markings and you may experience unnecessary or invalid warnings inthese 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 thecamera'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 road
construction.
• 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 Park Assist Works
If Model S is equipped with the Park Assist option, both the front and rear bumpers
include several sensors. When moving slowly
in Drive or Reverse, the sensors alert you if an object is detected close to the front or rear
bumper, respectively.Warning: The Park Assist images
provided below are representative only.
The exact number and location of Park
Assist sensors may vary depending on
the date your Model S was manufactured.
When driving less than 3 mph (4.8 km/h), the
sensors are activated.
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, causing
either no readings or false readings (see Limitations and False Warnings on page
55). Therefore, depending on Park
Assist to determine if Model S is
approaching an obstruction can result indamage 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
Whenever Model S is moving slowly inReverse or Drive at a speed of less than 3 mph
(4.8 km/h) , the left side of the instrument
panel provides feedback to alert you if an object is detected near the corresponding
back or front bumper. When reversing, visual feedback also displays on the touchscreen,
immediately below the camera view (see Rear
View Camera on page 64).
If chimes are turned on (see Controlling
Audible Feedback on page 54), 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.
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 ordamage 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. The chimes are muted
until you shift into a different gear or drive
over 3 mph (4.8 km/h).

Limitations and False WarningsThe parking sensors may not function
correctly in these situations:
• One or more of the parking sensors is damaged, dirty, or covered (such as mud,
ice, or snow).
• Object is located below approximately 8 inches (20 cm) (such as a curb or lowbarrier).
• Weather conditions (heavy rain, snow, or fog) are interfering with sensor operation.
• Object is thin (such as a sign post).
• A sensor’s operating range has been exceeded.
• Object is sound-absorbing or soft (such as powder snow).
• Object is sloped (such as a sloped embankment).
• Model S has been parked in, or being driven in, extremely hot or cold
temperatures.
• The sensors are affected by other electrical equipment or devices that
generate ultrasonic waves.
• Object is located too close to the bumper. • A bumper is misaligned or damaged.
• An object that is mounted to Model S is interfering with and/or obstructing the
sensor (such as a bike rack or a bumper
sticker).
Other Parking Aids
In addition to Park Assist, when shifted into
Reverse gear, the backup camera displays a
view of the area behind Model S. See Rear
View Camera on page 64.

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
58Model 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 traction control system
minimizes wheel spin by controlling brake
pressure and motor power.The electronic stability control
indicator displays on the instrument
panel whenever the traction control
system is actively controlling brake
pressure and motor power.Warning: Traction control does not
prevent accidents caused by driving
dangerously or turning too sharply at
high speeds.
Turning Off
Under normal conditions, you should leave
traction control on. Turn it off 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 turn traction control off, touch Controls >
Driving > Traction Control > Off .
The Traction Control Off indicator
displays at the top center of the
touchscreen whenever the traction
control system is turned off.
Although traction control turns on again
automatically the next time you start Model S,
turn it on using the touchscreen as soon as
the circumstances that required you to turn it off have passed.
