for the TPMS to trigger the Tire PressureWarning on the instrument panel.
Resetting the TPMS Sensors
After replacing one or more wheels, the TPMS sensors must be reset to ensure tire pressurewarnings are accurate. However, note that theTPMS sensors do not need to be reset after
replacing a tire or rotating wheels.
Note: When changing to 21" wheels
(Performance Plus models), the TPMS may
generate false tire pressure warnings. Bring
Model S to a Tesla Service center for further
adjustment.
Note: Do not reset the TPMS sensors in an
attempt to clear tire pressure warnings.
To reset TPMS sensors:
1. Inflate all tires to their recommend
pressures, as indicated on the Tire and Loading Information label located on the
driver’s door pillar.
2. Get ready to drive for ten minutes, then,
on the Model S touchscreen, touch
Controls > Settings > Service & Reset >
Tire Pressure Monitor > Reset Sensors .
3. Follow the onscreen instructions.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays frequently, contact Tesla to determine if a tiresensor needs to be replaced. Tire sensors
must be replaced by a Tesla service technician
who can perform a brief setup procedure. If a non-Tesla service center repairs or replaces atire, the tire sensor will not work until Tesla
performs the setup procedure.
TPMS Malfunction
Model S has also been equipped with a TPMS
malfunction indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the tire pressure
indicator light. When the system
detects a malfunction, the indicator
flashes for approximately one
minute after Model S powers on, and
then remains continuously lit. This
sequence continues upon
subsequent vehicle start-ups as long
as the malfunction exists. When the
TPMS malfunction indicator is on,
the system might not be able to
detect or signal under- and over-
inflated tires as intended.
TPMS malfunctions can occur for a variety of reasons, including installing replacement oralternate tires or wheels that prevent theTPMS from functioning properly. Alwayscheck the TPMS malfunction indicator light
after replacing one or more tires or wheels on
your vehicle 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 Repair KitYour Model S has no spare tire. Depending on
the legislations that apply to the region in which you purchased Model S, a tire repair kitmay or may not be included. If a tire repair kitwas not provided in Model S upon delivery,you can purchase one from Tesla.
Note: Although Model S does not have a spare
tire, in the event of a flat tire, Roadside
Assistance provides towing coverage for up
to 50 miles.
The tire repair kit consists of a compressor
and a canister of tire sealant (enough to repair
one tire). When injected into a tire, the sealant
can penetrate a small puncture up to 1/4"
(6 mm) to form a temporary repair.
Note: For punctures larger than 1/4” (6 mm),
severe tread damage, a damaged sidewall,
ripped tires or tires that have come off the
rim, call Roadside Assistance.
Warning: The tire repair kit is a temporary
repair only. You must repair or replace a
damaged tire as soon as possible.Warning: Do not exceed 30 mph
(48 km/h) when driving with a tire that
has been temporarily repaired with sealant.Warning: Follow all directions and
warnings on the tire repair kit before
starting a repair.Caution: Do not drive on a deflated tire as
this can cause serious damage.Tire Sealant Canister
The tire sealant provided in the Tesla tire repair kit is approved for use with Model S andis designed not to damage the TPMS (TirePressure Monitoring System) sensors.
Therefore, you must replace it only with one
of the same type and capacity (see Replacing
the Sealant Canister on page 117). Tire
sealant canisters can be purchased from Tesla.
The tire sealant has an expiration date printed
on the outside of the canister. If the expiration
date has passed, the sealant might not work as expected. Always replace an expired tire
sealant canister.Warning: Do not use any tire sealant
other than the one available from Tesla. Doing so could cause tire pressure
sensors to malfunction.Warning: Always read and follow the
safety and handling instructions printed on the sealant canister.Warning: Keep tire sealant out of the
reach of children.Warning: Tire sealant can be harmful if it
contacts the eyes or if swallowed or
inhaled. If the sealant comes into contact with your eyes, immediately flush withwater and seek medical attention ifirritation persists. If swallowed, do notinduce vomiting and seek medical
assistance immediately. If inhaled,
breathe fresh air. Inhalation can cause
drowsiness and dizziness. If breathing is
affected, seek medical assistance
immediately.

Uniform Tire Quality Grading
The following information relates to the tire
grading system developed by the National
Highway Traffic Safety Administration
(NHTSA), which grades tires by tread wear,
traction and temperature performance. Tires
that have deep tread, and winter tires, are
exempt from these marking requirements.
Where applicable, quality grades are found on
the tire’s sidewall between the tread shoulder and maximum section width. For example:
• TREADWEAR 180
• TRACTION AA
• TEMPERATURE A
The quality grades are described next. Note: In addition to the marking requirements,
passenger car tires must conform to Federal Safety Requirements.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified government test course.
For example, a tire graded 150 wears one and
a half times better on a government test
course than a tire graded 100. The relative
performance of tires depends on the actual
conditions of their use, however, and can depart significantly from the norm due to
variations in driving habits, service practices, road characteristics, and climate.
Traction
The traction grades, from highest to lowest,
are: AA, A, B, and C. These grades represent a
tire’s ability to stop on wet pavement as
measured under controlled conditions on test
surfaces of asphalt and concrete. A tire
marked C might have poor traction performance.Warning: Defective tires are dangerous.
Do not drive if a tire is damaged,
excessively worn, or is inflated to an
incorrect pressure. The safety of the
vehicle and occupants can be adversely
affected. Check tires regularly for wear
and to ensure there are no cuts, bulges or
exposure of the ply/cord structure.Warning: The traction grade assigned to
the tire is based on straight-ahead
braking tests, and doesn’t include:acceleration, cornering, hydroplaning or
peak traction characteristics.
Temperature
The temperature grades are A (the highest), B, and C, representing the tire’s resistance tothe generation of heat and its ability to
dissipate heat when tested under controlled
conditions on a specified indoor laboratory test wheel. Sustained high temperature cancause the tire to degenerate and reduce tirelife, and excessive temperature can lead to
sudden tire failure.
The grade C corresponds to the minimum
level of performance that all passenger car
tires must meet under the Federal Motor Safety Standard No. 109. Grades B and A
represent levels of performance on the
laboratory test wheel that exceed the
minimum requirements.
Warning: A tire’s temperature grade is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup and
possible tire failure.
