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 malfunction
Your 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 tire
sensor has been damaged. The aerosol
sealant can damage the sensor. Therefore,
whenever tire sealant has been used, the tire
sensor must be replaced.
Setting the tire pressures
Your vehicle allows you to use two sets of tire
pressures, refer to Specifications and tire
pressures, page 10-4.
Replacing a tire sensor
If 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. Tire sensors must be set up by
Tesla Motors. If a non-Tesla service center
repairs or replaces a tire, the tire pressure
monitoring sensor will not provide tire
pressure information until a Tesla service
technician has performed a brief set-up
procedure.
Type approval
The 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.
