■Measure
1 Reduce the vehicle speed.
Do not exceed a speed of 80
mph/130 km/h.
2 Stop at a filling station, etc.
and check the tire inflation

General information
Safety information
WARNING
A damaged regular tire with low or
missing tire inflation pressure
impacts handling, such as steer-
ing and braking response. Do not
continue driving if the vehicle is
equipped with normal tires.
If a tire inflation pressure
check is required
SymbolPossible cause
Inflation was not carried
out according to specifi-
cations, e.g., when the
tire has not been suffi-
ciently inflated or in the
case of a natural steady
tire pressure loss.
If the tire inflation pressure
is too low
A yellow warning light is
illuminated in the instru-
ment cluster.
SymbolPossible cause
There is a tire inflation
pressure loss.

message on the Control Display.
■Measure
Reduce your speed and stop
cautiously. Avoid sudden brak-
ing and steering maneuvers.
A low tire inflation pressure may

Control System to be switched
on.

1 Check the tire pressure and
correct as needed.
2 Perform a system reset.
If there is a significant loss
of tire inflation pressure
A yellow warning light is
illuminated in the instru-
ment cluster.
SymbolPossible cause
There is a flat tire or a
major loss in tire infla-
tion pressure.

detected a wheel
change, but no reset
was done.

tire inflation pressures
stored during the last

■Message
In addition, a symbol with a
vehicle message appears on the
Control Display.
■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.
If the tire inflation pressure
is too low
A yellow warning light is
illuminated in the instru-
ment cluster.

pressure loss.

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-
