Seat Heaters The front seats are equipped with heating
pads that operate at three levels from 3
(highest) to 1 (lowest). To operate the seat heaters, see Climate Controls on page 111.
If Model S is equipped with the optional cold
weather package, you can also control seat
heaters in all rear seating positions, as well as
heated wipers and washer nozzles by
touching Controls > Cold Weather (see
Controls on page 104).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.

Overview of Climate Controls
The climate controls are always available at the bottom of the touchscreen. By default, climate control is set to Auto, 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 (see Customizing Climate Control on page 112).
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, heated wipers, and heated steering wheel by touching Controls > Cold Weather (see Controls on page 104). When equipped with the optional
executive rear 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. 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. Touch the fan icon to customize and automate climate control settings (See Customizing
Climate Control on page 112.)
4. The windshield defroster distributes air
flow to the windshield. Touch once to turn on, touch a
second time to operate the heating and fan at their maximum level, and touch a third time to
turn
off and restore the air distribution, heating, and fan to their previous settings.
5. Turn climate control system on/off.
Note: The label on this button says Keep Climate On if you have set the climate control system
to maintain your temperature settings when parked (see Customizing Climate Control on
page 112).
6. The rear window defroster warms up the rear window for 15 minutes, then automatically shuts
off. Exterior side mirrors are also heated.
Note: Depending on date of manufacture and options selected at time of purchase, some
vehicles are not equipped with a heater in the exterior side mirrors.
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.

Customizing Climate ControlThe climate control system is designed to automatically provide optimum comfort in most
situations. All you need to do is set the desired temperature, and the air conditioning, air
recirculation, air distribution, and fan speed automatically maintain your selected temperature. You can even keep the climate control system on while you are away from the vehicle so that the
selected temperature is maintained.
To override the automatic setting, touch AUTO to customize individual settings. Then touch the
setting you want to change. When you change a setting, the AUTO icon turns from blue to gray
and RESET AUTO displays instead. Touch RESET AUTO to change all settings on the panel back to
their defaults. Or, you can touch AUTO associated with any individual setting to change it back to
its default.
In addition to the five settings shown above (and described below), if Model S is in Park, a Climate
Timer displays below the above popup (see Keep Climate On on page 114).
1. Touch RESET AUTO to change all settings back to their default values.
2. Touch A/C ON or A/C OFF to turn the air conditioning on and
off, respectively. Turning it offreduces cooling, but saves energy.
Because Model S runs much quieter than a gasoline-powered vehicle, you may notice the
sound of the A/C compressor as it is operating. To minimize noise, reduce the fan speed.

3.Choose how air is drawn into Model S:Outside air is drawn into Model S (see Ventilation on page 115). Although
less efficient than recirculating the air in very hot or cold climate
conditions, this setting draws more air into the rear seating areas, and is
recommended when occupants are seated in the Tesla built-in rear facing
child seats.Air inside Model S is recirculated. This prevents outside air (traffic fumes)
from entering, but reduces dehumidifying performance. Recirculating the
air is the most
efficient way to cool the front cabin area. To prevent the
windshield from fogging in some conditions, briefly change the setting
every hour to draw in outside air.
If your Model S is equipped with the HEPA (High Efficiency Particulate
Air) filter, you can ensure the best possible quality of air inside the cabin.
When selected, outside air is drawn in and filtered through the medical-
grade HEPA filter in addition to the secondary filtration systems. The
HEPA filter is extremely effective at removing particles, including
pollution, allergens, bacteria, pollen, mold spores, and viruses. Both the
HEPA
filter and the secondary filtration system also contain activated
carbon to remove a broad spectrum of odors and gases. When you
engage the HEPA option, the fan operates at the highest speed. In
addition, the positive pressure inside the cabin minimizes the amount of
outside air that can leak into the vehicle.
Note: Some gases, such as carbon monoxide, are not
effectively removed
by activated carbon.
4. Choose where air flows into the cabin. You can choose more than one location:
Foot-level ventsFace-level ventsWindshield vents
Note: When air is directed to the foot-level vents, approximately one third of the air continues
to flow to the windshield vents to assist in defogging. However, when air is directed to the
face-level vents, no air flows to the windshield because the air flowing through the face-level
vents may be adequate to assist in defogging the windshield.
5. Touch the arrows to set the speed of the fan.
Note: Adjusting the fan speed may change the selected setting for how air is drawn into
Model S in order to increase or reduce
airflow. If you set the fan speed very high (for example,
setting 10), Model S may automatically switch from drawing in outside air to recirculating air to achieve the high air
flow. Touch RESET AUTO to reset all settings to their default values.

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 20,000 km.
Cabin Overheat Protection The climate control system can reduce cabin
temperatures in extremely hot ambient conditions for a period of up to twelve hours
after you exit Model S. When enabled, air
conditioning turns on when cabin
temperatures exceed 40

Inspecting and Maintaining TiresRegularly inspect the tread and side walls for
any sign of distortion (bulges), foreign objects,
cuts or wear.Warning: Do not drive Model S if a tire is
damaged, excessively worn, or inflated to
an incorrect pressure. Check tires
regularly for wear, and ensure there are
no cuts, bulges or exposure of the ply/
cord structure.
Tire Wear
Adequate tread depth is important for proper
tire performance. Tires with a tread depth less
than 3 mm are more likely to hydroplane in
wet conditions and should not be used. Tires
with a tread depth less than 4 mm do not
perform well in snow and slush and should not
be used when driving in winter conditions.
Model S is originally
fitted with tires that have
wear indicators molded into the tread pattern. When the tread has been worn down to 3 mm,
the indicators start to appear at the surface of
the tread pattern, producing the
effect of a
continuous band of rubber across the width of
the tire. For optimal performance and safety,
Tesla recommends replacing tires before the
wear indicators are visible.
Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every
10,000 km.
Unbalanced wheels (sometimes noticeable as
vibration through the steering wheel)
affectvehicle handling and tire life. Even with regular
use, wheels can get out of balance. Therefore,
they should be balanced as required.
If tire wear is uneven (on one side of the tire
only) or becomes abnormally excessive, check
the alignment of wheels.
Note: When replacing only two tires, always
install the new tires on the rear.
Punctured Tires
A puncture eventually causes the tire to lose
pressure, which is why it is important to check tire pressures frequently. Permanently repair
or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when
penetrated, provided the object remains in the
tire. If, however, you feel a sudden vibration or
ride disturbance while driving, or you suspect a tire is damaged, immediately reduce your
speed. Drive slowly, while avoiding heavy
braking or sharp steering and, when safe to do so, stop the vehicle. Arrange to have Model S
transported to a Tesla Service Center, or to a nearby tire repair center.
Note: In some cases, you can temporarily
repair small tire punctures (under 6 mm) using
an optional tire repair kit available from Tesla.
This allows you to slowly drive Model S to Tesla or to a nearby tire repair facility.Warning: Do not drive with a punctured
tire, even if the puncture has not caused the tire to
deflate. A punctured tire candeflate suddenly at any time.
Flat Spots
If Model S is stationary for a long period in
high temperatures, tires can form
flat spots.
When Model S is driven, these flat spots cause
a vibration which gradually disappears as the
tires warm up and regain their original shape.
To minimize
flat spots during storage, inflatetires to the maximum pressure indicated on the tire wall. Then, before driving, release airto adjust tire pressure to the recommended
levels.
Improving Tire Mileage To improve the mileage you get from your
tires, maintain tires at the recommended tire
pressures, observe speed limits and advisory
speeds, and avoid:

Replacing Tires and Wheels
Tires degrade over time due to the
effects of
ultraviolet light, extreme temperatures, high
loads, and environmental conditions. It is
recommended that tires are replaced every six
years, or sooner if required.
Wheel and tires are matched to suit thehandling characteristics of the vehicle.
Replacement tires must comply with the
original
specification. If tires other than thosespecified are used, ensure that the load and
speed ratings marked on the tire (see Understanding Tire Markings on page 172)
equal or exceed those of the original
specification.
Ideally, you should replace all four tires at the same time. If this is not possible, replace the
tires in pairs, placing the new tires on the rear.
Always balance the wheel after replacing a
tire.
If you replace a wheel, the TPMS (Tire Pressure
Monitoring System) sensors need to be reset to ensure they provide accurate warnings
when tires are under- or
over-inflated (see
Resetting the TPMS Sensors on page 152).
For the
specification of the original wheels
and tires installed on Model S, see Wheels and
Tires on page 171.
Warning: For your safety, use only tires
and wheels that match the original
specification. Tires that do not match the
original specification can affect the
operation of the TPMS.
Warning: Never exceed the speed rating
of your vehicle

Cleaning the Interior
Frequently inspect and clean the interior to maintain its appearance and to prevent
premature wear. If possible, immediately wipe up spills and remove marks. For general
cleaning, wipe interior surfaces using a soft
cloth (such as
microfiber) dampened with a
mixture of warm water and mild non-
detergent cleaner (test all cleaners on a
concealed area before use). To avoid streaks,
dry immediately with a soft lint-free cloth.
Interior Glass
Do not scrape, or use any abrasive cleaning
fluid on glass or mirrored surfaces. This can
damage the reflective surface of the mirror
and the heating elements in the rear window.
Airbags
Do not allow any substance to enter an airbag
cover. This could
affect correct operation.
Dashboard and Plastic Surfaces
Do not polish the upper surfaces of the
dashboard. Polished surfaces are
reflectiveand could interfere with your driving view.
Leather Seats
Leather is prone to dye-transfer which can
cause discoloration, particularly on light colored leather. White and tan leather iscoated with an anti-soiling treatment. Wipespills as soon as possible using a soft cloth
moistened with warm water and non-
detergent soap. Wipe gently in a circular
motion. Then wipe dry using a soft, lint-free
cloth. Using detergents or commercially
available leather cleaners and conditioners is
not recommended because they can discolor or dry out the leather.
Polyurethane Seats
Wipe spills as soon as possible using a soft
cloth moistened with warm water and non-
detergent soap. Wipe gently in a circular
motion. After cleaning, allow the seats to air
dry.
Cloth Seats
Wipe spills as soon as possible using a soft
cloth moistened with warm water and non-
detergent soap. Wipe gently in a circular
motion. Then wipe dry using a soft, lint-free
cloth. Vacuum the seats as needed to remove
any loose dirt.
Carpets
Avoid over-wetting carpets. For heavily soiled
areas, use a diluted upholstery cleaner.
Seat Belts
Extend the belts to wipe. Do not use any type
of detergent or chemical cleaning agent.
Allow the belts to dry naturally while
extended, preferably away from direct
sunlight.
Tesla Built-In Rear Facing Child Seats
Vacuum the seats to remove any loose dirt. Wipe the seats with a soft cloth dampened
with warm water. You can also use an upholstery cleaner designed for automotive
use. Extend the belts to wipe. Allow the belts
to dry naturally, preferably away from direct
sunlight.
Touchscreen and Instrument Panel
Clean the touchscreen and instrument panel
using a soft lint-free cloth
specificallydesigned to clean monitors and displays. Do not use cleaners (such as a glass cleaner) and
do not use a wet wipe or a dry statically- charged cloth (such as a recently washed
microfiber). To wipe the touchscreen without
activating buttons and changing settings, you
can enable clean mode. Touch Controls >
Displays > Clean Mode . The display darkens to
make it easy to see dust and smudges.
Chrome and Metal Surfaces
Polish, abrasive cleaners or hard cloths can
damage the
finish on chrome and metal
surfaces.
Cautions for Interior Cleaning
Caution: Using solvents (including
alcohol), bleach, citrus, naphtha, or silicone-based products or additives on
interior components can cause damage.Caution: Statically-charged materials can
cause damage to the touchscreen or
instrument panel.Warning: If you notice any damage on an
airbag or seat belt, contact Tesla
immediately.Warning: Do not allow any water,
cleaners, or fabric to enter a seat belt
mechanism.Warning: Exposure to chemical cleaners
can be hazardous and can irritate eyes

Maintenance155

Checking Brake FluidWarning: Contact Tesla immediately if
you notice increased movement of the brake pedal or a
significant loss of brakefluid. Driving under these conditions can
result in extended stopping distances or complete brake failure.
The Brake indicator on the
instrument panel alerts you if the
quantity of
fluid in the brake
reservoir drops below the
recommended level. If it displays
while driving, stop as soon as safety
permits by gently applying the
brakes. Do not continue driving.
Contact Tesla immediately.
Fluid Level Check
Tesla checks the brake
fluid level at the
regularly scheduled maintenance intervals. To
check it yourself, park Model S on level
ground. When Model S is cool, remove the
maintenance panel (see Removing the
Maintenance Panel on page 159).
Check the fluid level visually by looking at the
outside marks on the side of the reservoir
without removing the
filler cap.
The brake
fluid level should always be
between the MIN and the MAX marks.
Note: Although brake
fluid level drops slightly
during normal use as a result of brake pad
wear, it should not drop below the MIN mark.
Topping Up the Brake Fluid
Do not top up your brake
fluid. Tesla service
does this when you bring Model S in for
regular servicing. The following instructions
are provided for information purposes and future reference only:
1. Clean the filler cap before removing it to
prevent dirt from entering the reservoir.
2. Unscrew the cap and remove it.
3. Top up the reservoir to the MAX mark
using the appropriate brake
fluid.4. Replace the filler cap, ensuring it is fully
secured.
Warning: Only use new fluid from a
sealed air-tight container. Never use
previously used
fluid or fluid from a
previously opened container
