Driving
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes the last values stored during
the reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
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.
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.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
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):
Under-inflation alert
The alert is kept active until the system is
reinitialised.
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.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
► Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
► Stop the vehicle as soon as it is safe to do
so.
– worsens road-holding.
– lengthens braking distances.
– causes premature wear of the tyres.
– increases energy consumption.
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.
The loss of pressure detected may not
always cause visible deformation of the
tyre.
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.
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).
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
With the vehicle stationary, the system
can be reinitialised in the
Settings>Vehicle touch screen application.
► Then select Safety > Tyre Pressure Setup.
