for example tyres with special
approval, the system must be
actively reset. The current tyre
inflation pressures are then
accepted as the specified values.
When operating the system, please
also comply with the other informa-
tion and notes in the Tyre inflation
pressure chapter, see page 292.
The following requirements must be
met for the system, otherwise relia-
ble signalling of a loss of tyre infla-
tion pressure is not ensured:
• After each tyre or wheel change,
the system has detected the fit-
ted tyres, updated the relevant
information and, after a short
journey, shown it on the Control
Display.
If the system does not detect the tyres
automatically, enter the specifications
for the fitted tyres in the tyre settings.
• RDC only becomes active after a
journey of several minutes:
• After a tyre or wheel change.
• After a reset, in the case of tyres with
special approval.
• After changing the tyre setting.
• In the case of tyres with special
approval:
• After every tyre or wheel change, a
reset must be carried out with the
correct tyre infl ation pressure.
• A reset must be carried out after the
tyre inflation pressure has been
adjusted to a new value.
• Wheels with TPM wheel elec-
tronics.
If the system does not detect the
tyres automatically, the specifica-
tions for the fitted tyres can be
entered in the tyre settings.
The tyre sizes of the fitted tyres can
be found in the tyre inflation pres-
sure information, see page 292, or
directly on the tyres.
The tyre specifications do not have
to be re-entered if the tyre inflation
pressure is corrected.
For summer and winter tyres, the
tyre data last entered for each type
is saved. This means that the set-
tings can be retrieved again after a
tyre or wheel change.
Safety note
WA R N I N G
The display showing the specified
tyre inflation pressures does not
replace the tyre inflation pressure information on the vehicle. If incorrect
data has been entered into the tyre
settings, the specified tyre inflation pressures will also be incorrect. As a
result, reliable signalling of a loss of
tyre inflation pressure can no longer be guaranteed. There is a danger of
injury and damage to property. Make
sure that the tyre sizes of the fitted tyres are displayed correctly and that
they match the specifications on the
tyres and the tyre inflation pressure information.

General
Safety note
WA R N I N G
A damaged standard tyre with too lit-
tle or no tyre inflation pressure impairs driving char acteristics, for
example steering and braking. Tyres
with run-flat properties allow a limited level of stability to be maintained.
There is a danger of accidents. Do
not continue driving if the vehicle is fit-
ted with standard tyres. Comply with the notes on run-flat tyres and contin-
uing to drive with these tyres.
If a tyre inflation pressure check is
required

properly, for example
insufficient air was added.

form a reset.
If no tyre damage can be identified, contact any authorized Toyota retailer
or Toyota authorized repairer, or any
reliable repairer.
2 Repair the flat tyre, for example
using a flat tyre kit or by chang-
ing the wheel.
The use of sealant, for example a
flat tyre kit, can damage the TPM
wheel electronics. Have the elec-
tronics replaced at the next oppor-
tunity.
■Safety notes
■Maximum speed
If a tyre is damaged you can con-
tinue your journey, but do not
exceed a maximum speed of 80
km/h, 50 mph.
■Continuing a journey with a
flat tyre
Note the following if you continue a
journey with a flat tyre:
1 Avoid violent or sudden braking
and steering manoeuvres.
2 Do not exceed a speed of 80
km/h, 50 mph.
3 As soon as there is an opportu-
nity, check the tyre inflation
pressure in all four tyres.
In the case of ty res with special approval: if all four tyres are inflated to
the correct tyre inflation pressures, the
Tyre Pressure Monitor might not have been reset. Perform a reset.
■Possible driving distance with
a deflated tyre
The possible driving distance varies
depending on the load and stresses
the vehicle is subjected to, for
example speed, road properties,
outside temperature. The driving
distance can be shorter or, if the
driving style is more careful, longer.
If the vehicle is moderately loaded
and used under favourable condi-
tions, it is possible to travel up to 80
km, 50 miles.
■Driving properties with dam-
aged tyres
On a journey with damaged tyres,
handling characteristics change
and may result in the following situ-
ations, for example:
• The vehicle losing traction more
quickly.
• Longer braking distances.
• Different self-steering character-
istics.
Adapt your driving style. Avoid
abrupt steering or driving over
obstacles, for example kerbs or
potholes.
Run-flat tyres
WA R N I N G
A run-flat tyre which has low tyre infla- tion pressure or no tyre inflation pres-
sure at all will change the vehicle's
handling characteristics, for example there may be reduced directional sta-
bility when braking, longer braking
distances and different self-steering characteristics. There is a danger of
accidents. Drive with care and do not
exceed a speed of 80 km/h, 50 mph.

3125-1. MOBILITY
■Final tyre failure
Vibration or loud noises during the
journey may be an indication that
the tyre has finally failed.
Reduce your speed and stop the
vehicle. Parts of the tyre could
detach, which might lead to an acci-
dent.
Do not continue driving, but contact
any authorized Toyota retailer or
Toyota authorized repairer, or any
reliable repairer.
The tyre inflation pressure depends
on the temperature of the tyre.
The tyre inflation pressure
increases as the tyre temperature
increases, for example during driv-
ing or due to exposure to sunlight.
Tyre inflation pressure decreases if
the tyre temperature drops.
Due to the given warning thresh-
olds, therefore, this behaviour may
trigger a warning if there are major
temperature drops.
After a temperature-related warn-
ing, the specified pressures are dis-
played again on the Control Display
after driving a short distance.
No warning can be given in the
event of extreme, sudden tyre fail-
ure caused by external factors.
Tyres with special approval: the
system will not function correctly if
a reset has not been carried out, for
example, a flat ty re is reported in
spite of the correct tyre pressure.
• A wheel without TPM wheel elec-
tronics is fitted, for example
emergency wheel: have the
wheels checked if necessary.
• Malfunction: have the system
checked.
• Fault due to systems or devices
with the same radio frequency:
the system is automatically reac-
tivated upon leaving the field of
interference.
• Tyre Pressure Monitor malfunc-
tion: have the system checked

or Toyota authorized repairer, or
