TESLA MODEL S 2018 Owner's Manual 

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

Seasonal Tire Types
Summer Tires
Your vehicle may be originally equipped with high performance summer tires or all season
tires. Tesla recommends using winter tires if
driving in cold temperatures or on roads
where snow or ice may be present. Contact
Tesla for winter tire recommendations.Warning: In cold temperatures or on
snow or ice, summer tires do not provide adequate traction. Selecting and installingthe appropriate tires for winter conditions
is important to ensure the safety and
optimum performance of your Model S,
even when equipped with dual-motors.
All-Season Tires
Your Model S may be originally equipped with
all-season tires. These tires are designed to provide adequate traction in most conditions
year-round, but may not provide the same level of traction as winter tires in snowy or icy
conditions. All-season tires can be
identifiedby “ALL SEASON" and/or "M+S” (mud and
snow) on the tire sidewall.
Winter Tires
Use winter tires to increase traction in snowy
or icy conditions. When installing winter tires,
always install a complete set of four tires at
the same time. Winter tires must be the same
size, brand, construction and tread pattern on all four wheels. Contact Tesla for winter tire
recommendations.
When equipped with winter tires, refer to the
tire warning label on the door pillar.
Winter tires can be identified by amountain/snowflake symbol on the
tire

Tire Pressure MonitoringEach tire should be checked monthly when
cold and
inflated to the recommended
pressures that are printed on the Tire and
Loading Information label located on the driver

TPMS malfunctions can occur for a variety of
reasons, including installing replacement or
alternate tires or wheels that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction indicator light after replacing one or more tires or wheels on yourvehicle to ensure that the replacement tires or
wheels allow the TPMS to continue to function
properly.
Note: If a tire has been replaced or repaired
using a
different tire sealant than the one
available from Tesla, and a low tire pressure is
detected, it is possible that the tire sensor has
been damaged. Contact Tesla to have the fault repaired as soon as possible.
Tire Care and Maintenance
Maintenance153

Cleaning the ExteriorTo prevent damage to the paint, immediately
remove corrosive substances (bird droppings, tree resin, dead insects, tar spots, road salt,
industrial fallout, etc.). Do not wait until
Model S is due for a complete wash. If
necessary, use denatured alcohol to remove
tar spots and stubborn grease stains, then
immediately wash the area with water and a
mild, non-detergent soap to remove the
alcohol.
Follow these steps when washing the exterior
of Model S:
1. Rinse Thoroughly
Before washing,
flush grime and grit from
the bodywork using a hose. Flush away
accumulations of mud in areas where
debris easily collects (such as wheel
arches and panel seams). If salt has been used on the highways (such as during
winter months), thoroughly rinse all traces of road salt from the underside of thevehicle.
2. Hand Wash
Hand wash Model S using a clean soft
cloth and cold or lukewarm water
containing a mild, high-quality car
shampoo.
3. Rinse with Clean Water
After washing, rinse with clean water to
prevent soap from drying on the surfaces.
4. Dry Thoroughly and Clean Exterior Glass
After washing and rinsing, dry thoroughly
with a chamois.
Clean windows and mirrors using an automotive glass cleaner. Do not scrape,
or use any abrasive cleaning
fluid on glass
or mirrored surfaces.
Cautions for Exterior CleaningCaution: Do not use windshield treatmentfluids. Doing so can interfere with wiper
friction and cause a chattering sound.Caution: Do not use hot water or
detergents.Caution: Do not wash in direct sunlight.Caution: If using a pressure washer,
maintain a distance of at least 30 cm
between the nozzle and the surface of
Model S. Keep the nozzle moving and do
not concentrate the water jet on any one
area.Caution: Do not aim water hoses directly
at window, door or hood seals, or through
wheel apertures onto brake components.Caution: Avoid using tight-napped or
rough cloths, such as washing mitts.Caution: If washing in an automatic car
wash, use Touchless car washes only. These car washes have no parts (brushes,
etc.) that touch the surfaces of Model S.
Using any other type of car wash could
cause damage that is not covered by the
warranty.Caution: Ensure the wipers are off before
washing Model S to avoid the risk of
damaging the wipers.Caution: Do not use chemical based
wheel cleaners. These can damage the
finish on the wheels.
Caution: Avoid using a high pressure
power washer on the camera(s) or
parking sensors (if equipped) and do not
clean a sensor or camera lens with a
sharp or abrasive object that can scratch
or damage its surface.Warning: Never spray liquid at a high
velocity (for example, if using a pressure
washer) towards the charge port while
Model S is charging. Failure to follow
these instructions can result in serious
injury or damage to the vehicle, charging
equipment, or property.
Cleaning
154Model S Owner

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

To preserve the cosmetic appearance of the
body, you can occasionally treat the paint surfaces with an approved polish containing:

Checking and Replacing WiperBladesCaution: Wiper blades do not lock into a
lifted position. When cleaning or
replacing a wiper blade, lift the wiper arm
only a short distance from the windshield,
just far enough to access the blade. Do
not lift a wiper arm beyond its intended
position. Doing so can cause damage that
is not covered by the warranty.
To make wiper blades easy to access, turn offthe wipers, shift Model S into Park, then use
the touchscreen to move them to the service
position. Touch Controls > Settings > Service
& Reset > Service Mode > ON .
Note: Wipers automatically return to their
normal position when you shift Model S out of Park.
Periodically check and clean the edge of the wiper blade and check the rubber for cracks,
splits and roughness. If damaged, replace the blade immediately to prevent damage to the
glass.
Contaminants on the windshield, or on the wiper blades, can reduce the
effectiveness of
the wiper blades. Contaminants include ice,
wax spray from car washes, washer
fluid with
bug and/or water repellent, bird droppings,
tree sap, and other organic substances.
Follow these guidelines for cleaning:

Warning: Do not operate the washers
while cleaning Model S. Windshield
washer
fluid can irritate eyes and skin.
Read and observe the washer fluidmanufacturer

Removing the Maintenance PanelTo check
fluid levels, remove the maintenance
panel:
1. Open the hood.
2. Pull the maintenance panel upward to
release the clips that hold it in place.
Caution: The maintenance panel protects
the front trunk from water. When re-
attaching, make sure it is fully seated.
Checking Battery Coolant
If the quantity of
fluid in the cooling system
drops below the recommended level, the
instrument panel displays a warning message.
Stop driving Model S as soon as safety
permits and contact Tesla.
Fluid Level Check
Tesla checks the Battery coolant level at the
regularly scheduled maintenance intervals.
On a single motor Model S, you can check the
fluid level visually. BUT DO NOT REMOVE THE
FILLER CAP AND DO NOT ADD FLUID. Doing
so can result in damage not covered by the
warranty.To check the
fluid level, park Model S
on level ground. When Model S is cool, remove
the maintenance panel (see Removing the
Maintenance Panel on page 159). The
fluidlevel can be seen by looking at the outside
marks on the side of the reservoir.
The fluid level should be between the MIN and
the MAX marks. If you notice that the fluidlevel has dropped significantly, contact Tesla
before using Model S.
Do Not Top Up Battery Coolant
Warning: Battery coolant can be
hazardous and can irritate eyes and skin.
Under no circumstances should you
remove the
filler cap and/or add coolant.
If the instrument panel warns you that the
fluid level is low, contact Tesla
immediately.
To maximize the performance and life of the
Battery, the cooling system uses a specificmixture of G-48 ethylene-glycol coolant
(HOAT). Contact Tesla for more specificinformation about the coolant.
