Tesla MODEL S Operating Manual page 178

3. Follow the onscreen instructions.
Caution: Selecting the incorrect wheel
size may result in false tire pressure
warnings. If a tire pressure warning
displays, exit the vehicle, close the
rear trunk and all doors, wait for the
touchscreen to go black, then re-
enter the vehicle and ensure that the
correct wheel size is selected before
touching Reset TPMS.
Note: On some older versions of Model S,
when changing to 21" wheels, the TPMS may
generate false tire pressure warnings. Bring
Model S to a Tesla Service Center for further
adjustment.
Warning: Do not reset the TPMS sensors
in an attempt to clear tire pressure
warnings.
Replacing a Tire Sensor
If the Tire Pressure warning indicator displays
frequently, contact Tesla to determine if a tire
sensor needs to be replaced. If a non-Tesla
Service Center repairs or replaces a tire, the
tire sensor may 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, 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 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 your
vehicle to ensure that the replacement tires or
wheels allow the TPMS to continue to function
properly.
Maintenance
Tire Care and Maintenance
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.
