Dashboard button
 Make a long press on this button. An audible signal confirms the reinitialisation.
Operating fault
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.
In this case, under-inflation monitoring of the tyres is no longer assured. Have the system checked by a CITROËN dealer or a qualified workshop.
Before doing anything to the system, the pressures of the four tyres must be checked and the system reinitialised.
