Tire Pressure Monitoring
System
WARNING: The TPMS is not a substitute
for manually checking tire pressures.
The TPMS only provides a tire pressure
warning and does not re-inflate the tires.
S
WARNING: The TPMS cannot register
damage to a tire. Regularly check the
condition of your tires.
S
The Tire Pressure Monitoring System (TPMS)
monitors the pressure of the tires using
sensors located in each wheel and receivers
located within the vehicle. The sensors
communicate with the receiver using Radio
Frequency (RF) signals.
Note: Installing accessories that are not
approved by Tesla Motors may interfere with
the TPMS system. Tire pressure warnings are displayed
on the instrument panel using an
amber warning indicator (telltale). A warning
is also displayed on the Touch Screen.
If the tire pressure warning light illuminates,
stop and check your tires as soon as possible
and inflate them to the correct pressure. If the
low pressure warning occurs frequently, the
cause must be determined and rectified.
The tire pressure warning indicator will
extinguish when all tires have been inflated to
the correct pressure.
TPMS malfunctionYour vehicle has 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. When the
system detects a malfunction, the indicator
will flash. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists.
When a malfunction occurs, the system may
not be able to detect or signal low tire
pressure as intended. TPMS malfunctions can
occur for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction indicator after
replacing one or more tires or wheels to
ensure that the replacement or alternate tires
and wheels allow the TPMS to function
properly. Note:
If a tire has been replaced or repaired
after using the tire sealant, and a low tire
pressure is detected, it is possible that the
wheel sensor has been damaged. The aerosol
sealant can damage the wheel sensor that
measures tire pressure. Therefore, whenever
tire sealant has been used, the wheel sensor
must be replaced.
Setting the tire pressuresYour vehicle allows you to use two sets of tire
pressures, refer to Specifications and tire
pressures, page 11-4 .Replacing a tire sensorIf you are experiencing frequent low tire
pressure warnings or the Touch Screen
reports a “Tire Pressure Hardware Fault”, the
system should be checked by Tesla Motors to
determine if a tire sensor requires
replacement.Type approvalThe TPMS devices comply with Part 15 of the
FCC rules and RSS-210. Operation is subject
to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept interference received, including interference that may
cause undesired operation.

Wheels and tires glossaryAccessory weightThe combined weight (in excess of those
items replaced) of items available as factory
installed equipment.BeadThe inner edge of a tire that is shaped to fit to
the rim and form an air tight seal. The bead is
constructed of steel wires which are
wrapped, or reinforced, by the ply cords.Cold tire pressureThe air pressure in a tire which has been
standing in excess of three hours, or driven
for less than one mile.Curb weightThe weight of a standard vehicle, including
any optional equipment fitted, and with the
correct fluid levels.Gross vehicle weightThe maximum permissible weight of a vehicle
with driver, passengers, load, luggage, and
equipment.kPa (kilo pascal)A metric unit used to measure pressure. One
kilo pascal equals approximately .145 psi.Maximum inflation pressureThe maximum pressure to which the tire
should be inflated. This pressure is given on
the tire side wall in lbf/in
2. Note: This pressure is the maximum allowed
by the tire manufacturer. It is not the pressure
recommended for use.
Maximum loaded vehicle weightThe sum of curb weight, accessory weight,
vehicle capacity weight, and production
options weight.Production options weightThe combined weight of options installed
which weigh in excess of 3 lb more than the
standard items that they replaced, and are
not already considered in curb or accessory
weights. PSI (lbf/in
2)
Pounds per square inch, unit of measure for
pressure.RimThe metal support for a tire, or tire and tube,
upon which the tire beads are seated.Vehicle capacity weightThe number of seats multiplied by 150 lb plus
the rated amount of load/luggage.
