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.

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.

Driving Tips to Maximize RangeYou can maximize your driving range usingthe same driving habits that you use to
conserve fuel in a gasoline-powered vehicle. In
addition to driving habits, energy
consumption depends on environmental conditions (such as cold weather and hillyroads). To get the maximum mileage from a
charge:
• Avoid frequent and rapid acceleration. • Instead of using the brake to slow down, move your foot off the accelerator.
Whenever Model S is moving and your
foot is off the accelerator, regenerative
braking slows down Model S and feeds
surplus energy back to the Battery (see
Regenerative Braking on page 53).
• Keep tires at the recommended inflation pressures (see Tire Care and Maintenance
on page 109).
• Lighten your load by removing any unnecessary cargo.
• Limit the use of resources such as heating and air conditioning. Using seat heaters to
keep warm is more efficient than heating the cabin. To automatically limit the
amount of power that the climate control system uses to maintain the temperatureof the Battery and the cabin area, touch
Controls > Driving > Range Mode > ON .
Note: On Dual Motor vehicles, you can turn on
Range Mode only when acceleration is set to Sport (if you change Acceleration to Insane,Range Mode automatically turns off).
The power meter on the instrument panel and
the Energy app (described next) provide
feedback on energy usage. With this
feedback, you will soon become familiar with how driving habits and environmental
conditions impact how much energy Model S
is using.
Energy App Use the energy app to view real-time and
projected energy usage. Choose from two
types of charts:
• Consumption Chart: - display how much energy Model S has consumed over thepast 5, 15 or 30 miles (10, 25 or 50 kms).
• Trip Chart - If your Model S is equipped with the navigation option, you can trackthe amount of energy being consumed
while navigating to a destination. The gray
line represents predicted usage and the
green line represents actual usage. Touchthe zoom icon in the top right corner to change the zoom level.
Note: The Trip Chart displays energy usage
only if you are currently navigating to a destination.
Note: In some situations, values and distances
on the Trip chart may be inaccurate. For example, when charging Model S during anactive navigation route. To resolve
inaccuracies, cancel and reinitiate navigation to the destination.
Saving Energy Model S has an energy-saving feature that
reduces the amount of energy being
consumed when Model S is not in use. Touch Controls > Displays > Energy Saving and
choose from the following options:
• OFF . All display systems remain powered
when Model S is not in use, providing the most responsive experience. More energy
is consumed.
• NIGHTLY . Model S shifts to the energy-
saving mode at night (10 pm to 5 am).
• ON. Significantly less energy is consumed
whenever Model S is not in use. The start-
up time of the instrument panel and
Bluetooth could be slower.
• Always Connected . Preserves cell
connectivity when energy saving is active.
This allows the mobile app to connect to
Model S more quickly, and provides
immediate 3G internet access when entering the car. Slightly more energy isconsumed.

Touch the circled X in the top left corner
of a window to close it (or you can touch anywhere outside the window).
2. Sunroof
If Model S is equipped with a sunroof,
touch to adjust its position (see Sunroof
on page 15).
3. Suspension
If Model S is equipped with Smart Air
Suspension, touch to manually raise or lower Model S, or to remove a previously
saved auto-raising location (see Smart Air
Suspension on page 83). Model S must
be powered on and you must press the
brake pedal before you can change
suspension settings. Smart Air Suspension
causes Model S to self-level, even when
powered off. Therefore, when towing or
lifting, you must disable self-leveling (see
Instructions for Transporters on page 150
and Jacking and Lifting on page 132).
4. Driving
• Steering mode Adjust the amount of effort requiredto turn the steering wheel. Sport feels
more responsive whereas Comfort
feels easier to drive and park (see
Steering Wheel on page 37).
• Acceleration (Dual Motor vehicles only)
Choose an acceleration level. Sport is the standard level of acceleration and allows you to maximize driving range(see the Range Mode setting below).
Choose Insane if you want to increase
peak torque by approximately 50 per cent. If you choose Insane, the Range
mode setting, if on, automatically turns off.
• Creep
When on, Model S slowly movesforward when in Drive and backward
in Reverse when you release the brake
(similar to a conventional vehicle with an automatic transmission). You can
adjust this setting only when Model S
is in Park.
• Traction ControlTo allow the wheels to spin on a
standard single motor Model S, you can turn off traction control. On a dualmotor Model S, you can enable Slip
Start. If you turn off Traction Control
(or enable Slip Start), a warning
message displays on the instrument
panel. Traction control turns off for
the current drive only. On dual motor
vehicles, traction control is
automatically turned on again when the speed exceeds 40 mph
(64 km/h). See Traction Control on
page 54.
• Regenerative braking
When you release the accelerator
when driving, regenerative braking
slows Model S and feeds any surplus
energy back to the Battery. If set to
Low, Model S does not slow down as
quickly, but you may experience less range (see Regenerative Braking on
page 53).
Note: Regardless of the setting, the
energy gained by regenerative
braking is reduced if the Battery is
full, or if it is extremely cold or hot
(the surplus energy is used to heat or
cool the Battery).
• Range Mode
If on, Model S conserves energy by
limiting the power of the climate
control system. Cabin heating and
cooling may be less effective, but seat
heaters turn on to compensate. In
Dual Motor vehicles, Range Mode can
be turned on only when acceleration
is set to Sport (see above).
5. Cold Weather
If Model S is equipped with the cold
weather option, you can control all seat heaters as well as the heated wipers andsteering wheel. Heaters that are turned on
are displayed in red. To turn off all seat
heaters, touch All Off. Note that you can
also control the front driver and
passenger seats using the main climate
control panel located on the bottom of

Overview of Climate ControlsThe climate controls are always available at the bottom of the touchscreen. By default, climate
control is set to Auto On, which maintains optimum comfort in all but the most severe weather conditions. When you adjust the temperature, the system automatically adjusts the heating, air
conditioning, air distribution, air circulation, and fan speed to maintain your selected temperature.
To override these settings, touch Auto On (see Customizing Climate Control on page 81).
The fan, heating, and air conditioning systems are powered by the Battery. Therefore, prolonged use decreases driving range.
Note: The following illustration is provided for demonstration purposes only. Depending on
vehicle options, software version, market region, and settings, the information displayed may be
slightly different.1. The front seats are equipped with heating
pads that operate at three levels from 3
(highest) to 1 (lowest).
When operating, the indicator turns red
and displays the setting number.
Note: If Model S is equipped with the
optional cold weather package, you can
also control seat heaters in the rear seats
as well as heated wipers by touching
Controls > Cold Weather (see Controls on
page 74). When equipped with executive seats, you can control the seat and the
backrest separately in each second row
passenger seat.
2. Touch the up or down arrow to set the
cabin temperature (from LO, 63° F to
HI, 90° F/LO, 17° C to HI, 32° C). To apply
a temperature setting to both the driver
and passenger side at the same time,
touch SYNC TEMP on the temperature
popup that appears when you touch an
arrow.
3. Automatic/Manual climate control (see
Customizing Climate Control on page

flow to the windshield and operates the
heating and fan at their maximum level.
Touch once for Normal Defrost and twice
for Max Defrost. When on, touch again to
turn off and restore the air distribution,
heating, and fan to their previous settings.
5. Turn climate control system on/off.
6. The rear window defroster warms up the
rear window* for 15 minutes, then
automatically shuts off.
*If Model S is equipped with the optional
tech package, exterior side mirrors are
also heated.Warning: To avoid burns resulting from
prolonged use, individuals who have
peripheral neuropathy, or whose capacity to feel pain is limited because of diabetes,
age, neurological injury, or some other
condition, should exercise caution when using the climate control system and seat
heaters.

80Model S Owner's Manual

Ventilation
Outside air is drawn into Model S through the
grill in front of the windshield. Keep the grill
clear of obstructions such as leaves and snow.
To direct the flow of air inside Model S, move
the interior vents up, down, or from side to
side.
Note: You can direct the outer face level vents
toward the side windows to help defrost or defog them.
Cabin Air Filter
Model S has an air filter that prevents pollen,
industrial fallout, road dust and other particles
from entering through the vents. Tesla replaces the air filter at the regularly
scheduled maintenance intervals of every 12 months, or every 12,500 miles (20,000 km).
Climate Control Operating Tips
• To conserve energy, you can limit the power of the climate control system by
turning on Range Mode. Cabin heating and cooling may be less effective, butseat heaters turn on to compensate.
Touch Controls > Driving > Range Mode .
• If the climate control system operates more loudly than you prefer, reduce thefan speed or adjust the air flow to draw in
outside air (instead of recirculating).
• In addition to cooling the interior, the air conditioning system also cools the
Battery. Therefore, in hot weather, the air
conditioning system can turn on even if
you turned it off. This is normal because the system’s priority is to cool the Battery
to ensure it stays within an optimum
temperature range to support long life and optimum performance.
• To ensure the climate control system operates efficiently, close all windows and
ensure that the exterior grill in front of the
windshield is free of ice, snow, leaves, and
other debris.
• To reduce the time it takes to reach a comfortable temperature in hot weather,
drive with the windows slightly open for a
few minutes when you first start driving.
• In very humid conditions, it is normal for the windshield to fog slightly when you
first turn on the air conditioning. This fog
clears within a few seconds.
• It is normal for a small pool of water to form under Model S when parked. Extra
water produced by the dehumidifying
process is drained underneath.
