Driving
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Snow chains
Reinitialisation
Reinitialise the system after adjusting one or
more tyre pressures and after changing one or
more wheels.
The system does not have to be
reinitialised after fitting or removing snow
chains.
Under-inflation detection does not
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) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
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.
Under-inflation alert
This is signalled by the fixed illumination
of this warning lamp, accompanied by an
audible signal and 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.
– worsens road-holding.
– lengthens braking distances.
– causes premature wear of the tyres.
– increases fuel consumption.
With the vehicle stationary, the system is
reinitialised via the Driving /
Vehicle touch screen menu.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not rely on just a visual check.
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.
Malfunction
► Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make 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).
These warning lamps come on in
the event of a malfunction.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds).
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Otherwise, add 0.3 bar to the pressures
shown on the label.
The alert is kept active until the system is
reinitialised.
