Automatic Reset of TPMS Sensors
After replacing one or more wheels (but not
after replacing a tire), the TPMS sensors are
relearned to ensure tire pressure warnings are
accurate. TPMS sensors reset automatically
within 10 minutes of driving over 15 mph
(25 km/h).
Warning: If your Model Y is equipped with
aftermarket tires that dier in size from
those printed on the Tire and Loading
Information Label (see Vehicle Loading
on page 184), it is the driver's
responsibility to determine the correct
tire pressure. Do not drive on public roads
when tires are not inflated to the correct
pressure.
Warning: Do not depend on TPMS
sensors to accurately determine pressures
and trigger alerts. It is the driver's
responsibility to maintain correct tire
pressures (see Maintaining Tire Pressures
on page 167). Over or under-inflated tires
can result in loss of control or tire
damage, which can lead to serious injury.
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 Y 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-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.
Note: If a tire has been replaced or repaired
using a dierent 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.
