Driving
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.

Malfunction
The flashing and then fixed illumination of the

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 PEUGEOT
dealer or a qualified workshop.
Before doing anything to the system,
the pressures of the four tyres must be
checked and the system reinitialised.
