Malfunction
The flashing and then fixed
illumination of the under-inflation
warning lamp indicates a fault with
the system.
In this case, the pressure in the tyres is no
longer monitored.
This alert is also displayed if:
- one or more wheels is not fitted with a
sensor,
- there is a wireless device using the same
frequency near the vehicle,
- there is snow or ice build-up in the wings or
in the rims,
- the tyre pressure monitoring system battery
charge level is insufficient,
- the wheel sensor identifiers have not been
logged by a CITROËN dealer or a qualified
workshop.
Go to a CITROËN dealer or a qualified
workshop to have the system checked or,
following a puncture, to have the original
wheel, equipped with a sensor, refitted
with a tyre.

Any tyre repair or replacement on a wheel
fitted with this system must be carried
out by a CITROËN dealer or a qualified
workshop.
If you fit the second set of tyres stored
in the system, the malfunction alert will
appear until this second set is selected in
the configuration menu.
Managing sets of tyres
If you have registered a second set of tyres with
a CITROËN dealer or a qualified workshop,
every time the set of tyres is changed (e.g.
"winter" tyre), select the set you have just
installed in the configuration menu.
Once the new set has been fitted, check
and adjust the pressure to the value stated
on the tyre pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
The other set of tyres is selected via the
instrument panel display screen, with the
ignition on and the vehicle stationary.
