printed Owner's Manual.
With Tire Pressure Monitor
TPM:
The corrected tire inflation pres-
sures are applied automatically.
Make sure that the correct tire
settings have been made.
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.
Depending on the previous dis-
plays, the status display
appears when the engine is run-

been driven for at least 30 min-
utes.

tire inflation pressure levels
deviate from the intended tire
pressure value.
5 Correct the tire inflation pres-
sure if the actual tire inflation
pressure deviates from spec-
ified tire inflation pressure.
The display of the current tire
pressure may be limited when
the vehicle is stationary. After a
short drive, the tire pressure is
updated.
With tires that cannot be found

the Control Display, reset the
Tire Pressure Monitor TPM.
For speeds of up to 100
mph/160 km/h and for optimum
driving comfort, note the pres-
sure values in the tire inflation
pressure table, refer to page
273, and adjust as necessary. These pressure values can also
be found on the tire inflation
pressure label on the driver's
door pillar.
Do not exceed a speed of 100
mph/160 km/h.

pressure values.
If tires are being used that are
not specified on the tire inflation
pressure details on the vehicle,
refer to page 270, 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 270.
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-
p l a y.
Enter the inform
ation about the
mounted tires in th e tire settings
when the system does not automat-
ically detect the tires.
• TPM does not activate until
after driving for a few minutes:
• After a tire or wheel replacement.
• Reset, for tires without special approval.
• After changing the tire setting.
• For tires with special approval:
• After a tire or wheel replacement, a reset was perfo rmed with the
correct tire inflation pressure.
• After the tire inflation pressure was adjusted to a new value, a
reset was p erformed.
• 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 270, or
directly on the tires.
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.

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.

Actions in the event of a
flat tire

2945-1. MOBILITY
2Repair 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.
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.
• Tire Pressure Monitor mal- function: have the system
checked by your Toyota
dealer.
• Each tire, including the spare (if provided) should be
checked monthly when cold
and inflated to the inflation
pressure recommended by
the vehicle manufacturer on
the vehicle placard or tire
inflation pressure label. (If
your vehicle has tires of a dif-
ferent size than the size indi-
cated on the vehicle placard
or tire inflation pressure label,
you should determine the
proper tire inflation pressure
for those tires.) As an added
safety feature, your vehicle
has been equipped with a tire
pressure monitoring system
(TPMS) that illuminates a low
tire pressure telltale when one
or more of your tires is signifi-
cantly under-inflated. Accord-
ingly, when the low tire
pressure telltale illuminates,
you should stop and check
your tires as soon as possi-
ble, and inflate them to the
proper pressure. Driving on a
significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces
fuel efficiency and tire tread
life, and may affect the vehi-
cle's handling and stopping
ability. Please note that the
TPMS is not a substitute for
proper tire maintenance, and
it is the driver's responsibility
to maintain correct tire pres-
sure, even if under-inflation
has not reached the level to
trigger illumination of the
TPMS low tire pressure tell-
tale. Your vehicle has also
been equipped with a TPMS
malfunction indicator to indi-
cate when the system is not
operating properly. The TPMS
malfunction indicator is com-
bined with the low tire pres-
sure telltale. When the system
detects a malfunction, the tell-
tale will flash for approxi-
mately one minute and then
remain continuously illumi-
nated. 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 func-
