NOTES
This information generally
records the state of a compo-
nent, a module, a system, or the
environment, for instance:
• Operating states of system components, e.g., fill levels,
tire inflation pressure, battery
status.
• Malfunctions and faults in important system compo-
nents, for instance lights and
brakes.
• Responses by the vehicle to special situations such as air-
bag deployment or engage-
ment of the driving stability
control systems.
• Information on vehicle-dam- aging events.
The data is required to perform
the control device functions.
Furthermore, it also serves to
recognize and correct malfunc-
tions, and helps the vehicle
manufacturer to optimize vehicle
functions.
The majority of this data is tran-
sient and is only processed
within the vehicle itself. Only a
small share of the data is stored
event-related in event or fault
memories.
When servicing, for instance
during repairs, service pro-
cesses, warranty cases, and
quality assurance measures,
this technical information can be
read out from the vehicle
together with the vehicle identifi- cation number.
Your Toyota dealer can read out
the information. The socket for
OBD Onboard Diagnosis
required by law in the vehicle is
used to read out the data.
The data is collected, pro-
cessed, and used by the rele-
vant organizations in the service
network. The data documents
technical conditions of the vehi-
cle, helps with the identification
of the fault, compliance with
warranty obligations and quality
improvement.
Furthermore, the manufacturer
has product monitoring duties to
meet in line with product liability
law. To fulfill these duties, the
vehicle manufacturer needs
technical data from the vehicle.
The data from the vehicle can
also be used to check customer
claims for warranty and guar-
anty.
Fault and event memories in the
vehicle can be reset when your
Toyota dealer performs repair or
servicing work.
Depending on the vehicle equip-
ment, comfort and Customize
settings can be stored in the
vehicle and modified or reset at

The tire inflation pressure speci-
fications can be found in the tire
inflation pressure table in the
printed Owner's Manual.
With Tire Pressure Monitor
TPM:
With tires that cannot be found
in the tire pressure values on
the Control Display, reset the
Tire Pressure Monitor TPM.
Regularly check the tire inflation
pressure and correct it as
needed:
• At least twice a month.
• Before embarking on an extended trip.
The friction during hard braking
may produce brake dust and make the rims dirty. Brake dust
can be removed by cleaning the
rims. Toyota recommends using
vehicle care and cleaning prod-
ucts from Toyota.
A current measured value is
available after approx. 30 min-
utes of normal driving.

Reset the Tire Pressure Monitor
TPM, refer to page 282.
Replace the nonworking tire and
the sealant container of the
Mobility System promptly.
Tire chains cannot be mounted.
Snow tires should be used
instead.
The system monitors tire infla-
tion pressure in the four
mounted tires. The system
warns you if there is a loss of
pressure in one or more tires. Sensors in the tire valves mea-
sure the tire inflation pressure
and tire temperature.
The system detects the
mounted tires automatically. The
system displays the specified
nominal pressure values on the
Control Display and compares
these values to the actual tire
pressure values.
If tires are being used that are
not specified on the tire inflation
pressure details on the vehicle,
refer to page 248, such as tires
with special approval, the sys-
tem needs to be actively reset.
The system will then take over
the actual tire inflation pressures
as the target pressures.
When operating the system,
also note the additional informa-
tion found in the Tire inflation
pressure, refer to page 248,
chapter.

The following conditions must
be met for the system; other-
wise, reliable flagging of a loss
of tire inflation pressure is not
assured:
• After each tire or wheel change, the system detects
and updates the mounted
tires and displays them after a
short trip on the Control Dis-
play.
Enter the information about the
mounted tires in th e tire settings
when the system does not automat-
ically detect the tires.
• For tires with special
approval:
• After a tire or wheel replacement, a reset was performed with the
correct tire inflation pressure.
• After the tire inflation pressure was adjusted to a new value, a
reset was performed.
• Wheels with TPM wheel elec-
tronics.
The information about the
mounted tires can be entered in
the tire settings if the system
does not automatically detect
the tires.
The tire sizes of the mounted
tires can be gathered from the
tire inflation pressure details on
the vehicle, refer to page 266, or
directly on the tires.
The tire details do not need to
be re-entered when the tire infla-
tion pressure is corrected.
For summer and winter tires, the
tire details entered last are
stored. After a tire or wheel
replacement, the settings of the
tire sets used last can be
selected.

Safety information
WARNING
The display of the target pres-
sures is not a sub
stitute for the
tire inflation pressure details on
the vehicle. Incorrect entries in
the tire settings can lead to incor-
rect target tire inflation pressure
values. In this case, it cannot be
guaranteed that the notification of
a loss of tire inflation pressure will
be reliable. There is a risk of injury
and risk of damage to property.
Ensure that the tire sizes of the
mounted tires are displayed cor-
rectly and match the details on the
tires and on the vehicle.

■Measure
1 Reduce the vehicle speed.
Do not exceed a speed of 80
mph/130 km/h.
2 At the next opportunity, for
instance at a gas station,
check the tire inflation pres-
sure in all four tires and cor-
rect if necessary.
3 Reset the system.
■Message
In addition, a symbol with the
affected tire appears in a vehicle
message on the Control Display.
■Measure
Reduce your speed and stop
cautiously. Avoid sudden brak-
ing and steering maneuvers.
1 Identify the damaged tire.
Check the tire inflation pressure in
all four tires, for instance using the
tire pressure gauge of a flat tire kit.
For tires with special approval: if
the tire inflation pressure in all four
tires is correct, t he TPM may not
have been reset. In this case, per-
form the reset.
If tire damage cannot be found,
contact your Toyota dealer.
2 Repair the flat tire, e.g., with
a flat tire kit or by changing
the wheel.
Use of sealant, for instance from
the flat tire kit, may damage the
TPM wheel electronics. Have
the electronics replaced at the
next opportunity.

MOBILITY
The tire inflation pressure
depends on the tire's tempera-
ture.
Driving or exposure to the sun
will increase the tire's tempera-
ture, thus increasing the tire
inflation pressure.
The tire inflation pressure is
reduced when the tire tempera-
ture falls again.
These circumstances may
cause a warning when tempera-
tures fall very sharply.
Following a temperature-related
warning, the target pressures
are displayed on the Control
Display again after a short dis-
tance.
The system cannot indicate sud-
den serious tire damage caused
by external circumstances.
Tires with special approval: the
system will not function correctly
if a reset was not performed, for
example a flat tire may be indi-
cated although the tire inflation
pressures are correct. • A wheel without TPM wheel
electronics, such as an emer-
gency wheel, is mounted:
have the wheels checked, if
needed.
• Malfunction: have the system checked.
• Interference caused by sys- tems or devices with the
same radio frequency: after
leaving the area of the inter-
ference, the system automati-
cally becomes active again.
• For tires with special approval: the system was
unable to complete the reset.
Perform a system reset again.
• Each tire, including the spare (if provided) should be
checked monthly when cold
and inflated to the inflation
