The tyre under-inflation detection cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high speed,
long journey):

The inflation pressures defined for the
vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly when
the tyres are "cold" (vehicle stopped for 1 hour
or after a journey of less than 6 miles (10 km)
at moderate speeds).
Otherwise, add 0.3 bar to the pressures shown
on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation alert
This is signalled by the fixed illumination
of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
►  Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
►  Stop the vehicle as soon as it is safe to do so.
The loss of pressure detected may not
always cause visible deformation of the
tyre.
Do not rely on just a visual check.
►  Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of all four tyres when cold.
►  If it is not possible to carry out this check
immediately, drive carefully at reduced speed.
►  In the event of a puncture, use the temporary
puncture repair kit or the spare wheel (depending
on equipment).
Driving too slowly may not ensure
optimum monitoring.
The alert is not immediately triggered in the
event of a sudden loss of pressure or tyre blow-
out. This is because analysis of the values read
by the wheel's speed sensors can take several
minutes.
The alert may be delayed at speeds below 25
mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is
reinitialised.
Reinitialisation
►  The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system
can be reinitialised in the Settings>Vehicle
touch screen application.
►  Then select Safety > Tire Pressure Setup.
►  Press YES to confirm.
The reinitialisation is confirmed by the display of
a message and an audible signal.
