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).
Otherwise, add 0.3 bar (30 kPa) to the
values indicated on the label.
Under-inflation alert
This is indicated by continuous
illumination of this warning lamp,
an audible signal and, depending
on equipment, the display of
a message.
F
Reduce speed immediately, avoid excessive
steering movements and sudden braking.
F
Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check.
F
If it is not possible to make this check
immediately, drive carefully at reduced
speed.
or
F
In case of a puncture, use the temporary
puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is
reinitialised.
Reinitialisation
The system must be reinitialised after any
adjustment to the pressures of one or more
tyres, and after changing one or more wheels.
Before reinitialising the system, ensure
that the pressures of the four tyres
are correct for the conditions of use
of the vehicle and conform to the
recommendations on the tyre pressure
label.
The under-inflation alert can only be relied
on if the reinitialisation of the system has
been done with the pressures in the four
tyres correctly adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Reinitialisation of the system is done on the
touch screen, with the ignition on and the
vehicle stationary.
F
In the Driving menu, select the " Driving
functions " tab, then " Under-inflation
initialisation ".
F
Confirm the instruction by pressing " Yes ",
an audible signal and a message confirm
the reinitialisation.
The new pressure parameters saved are
treated as reference values by the system.
Malfunction
F
If you have a compressor, such as the one
in the temporary puncture repair kit, check
the pressures of the four tyres when cold.
In this case, under-inflation monitoring of the
tyres is no longer provided.
Have the system checked by a CITROËN
dealer or a qualified workshop.
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the Service warning lamp
indicates a fault with the system.
A message appears, accompanied by an
audible signal.
