for the respective load conditions
will apply, in accordance with the
vehicle's actual load condition.
Example: for a partially loaded
vehicle, the optimum tyre inflation
pressure is the one stated for a par-
tially loaded vehicle.
More information regarding wheels
and tyres can be obtained from any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
The current tire pressure of each
installed wheel can be displayed on
the control display.
To ensure that they are displayed
correctly, the tyre sizes must be
stored in the system and must have
been set, see page 290, for the
mounted tyres.
The current tyre inflation pressure
value is shown on each tyre.Tyres heat up while driving. The
tyre inflation pressure increases
with the temperature of the tyre.
Tyres have a natural, uniform loss
of tyre inflation pressure.
Inflating devices can display a pres-
sure that may be up to 0.1 bar too
low.
The tyre inflation pressure inscrip-
tions on the tyre inflation pressure
sign on the door pillar only relate to
cold tyres or tyres at the same tem-
perature as the ambient tempera-
ture.
Only check the tyre inflation pres-
sures when the tyres are cold, i.e.:
• A driving distance of max. 2 km,
1.25 miles has not been
exceeded.
• If the vehicle has not moved
again for at least 2 hours after a
journey.
Regularly check the tyre inflation
pressure of the emergency wheel in
the boot and correct the pressure if
necessary.

WARNING
The inflation pressures on the tyre
label are applicable only for tyres
explicitly mentioned on the label.
Inflation pressures for tyres that may
be covered by the label – by size,
speed category and load rating/load
index – but not explicitly mentioned
on the label may be different. Please
obtain adequate inflation pressures in
accordance with the tyre manufac-
turer's specifications from your tyre
dealer.

Tire chains cannot be mounted.
Snow tires should be used instead.
The system monitors the tyre infla-
tion pressure in the four fitted tyres.
The system warns if the tyre infla-
tion pressure in one or more tyres
has fallen.
Sensors in the tyre valves measure
the tyre inflation pressure and tyre
temperature.
The system detects the fitted tyres
automatically. The system shows
the preset specified pressures on
the Control Display and compares
them to the current tyre inflation
pressures.
If tyres are fitted which are not
listed on the tyre inflation pressure
labels in the vehicle, see page 278, for example tyres with special
approval, the system must be
actively reset. The current tyre
inflation pressures are then
accepted as the specified values.
To operate the system, also please
comply with the other information
and notes in the chapter Tyre infla-
tion pressure, see page 278.
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.

NOTICE
■Driving with tire chains
Do not fit tire chains. Tire chains may
damage the vehicle body and sus-
pension, and adversely affect driving
performance.

Safety note
WARNING
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.
