TPMS Malfunction
Your vehicle 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 low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the system
may not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may 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
telltale after replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function properly.
The TPMS malfunction indicator is combined
with the tire pressure indicator light. If Model
Y detects a fault with the TPMS, this indicator
flashes for one minute whenever you power on
Model Y.
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.
NOTE: Installing accessories that are not approved by Tesla
can interfere with the TPMS.
CAUTION: Avoid placing powered USB devices near
the card reader on the center console as powered USB
devices may interfere with the tire pressure monitoring
system.
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 two minutes of driving over 25 km/h.
WARNING: If your Model Y is equipped with
aftermarket tires that differ in size from those printed
on the Tire and Loading Information Label, 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
173). 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, use
the mobile app to schedule a service appointment 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.
Seasonal Tire Types
Understand Your Tire Type
The type of tires that your vehicle is originally equipped with
depends on vehicle model and market region. It is important
to understand the capabilities of your vehicle's tires and
whether they are suited for summer, all-season, or winter
driving. Check the information on the sidewall of a tire for
information about a tire's performance characteristics (see
Understanding Tire Markings on page 200).
Summer and All-Season Tires
Summer tires and all season tires are designed for maximum
dry and wet road performance but are not designed to
perform well in winter conditions. All-season tires are
designed to provide adequate traction in most conditions
year-round, but may not provide the same level of traction as
winter tires in snowy or icy conditions. All-season tires can
be identified by āALL SEASON" and/or "M+Sā (mud and
snow) on the tire sidewall.
If driving in cold temperatures or on roads where snow or ice
may be present, Tesla recommends using winter tires.
WARNING: In cold temperatures or on snow or ice,
summer and all-season tires do not provide adequate
traction. Selecting and installing the appropriate tires
for winter conditions is important to ensure the safety
and optimum performance of your Model Y.
Winter Tires
Use winter tires to increase traction in snowy or icy
conditions. When installing winter tires, always install a
complete set of four tires at the same time. Winter tires must
be the same diameter, brand, construction and tread pattern
on all four wheels.
Winter tires can be identified by a mountain/
snowflake symbol on the tire's sidewall.
When driving with winter tires, you may experience more
road noise, shorter tread life, and less traction on dry roads.
