Puncture
The STOP warning lamp comes on and this warning lamp is
displayed in the instrument panel, accompanied by an audible
signal and an alert message identifying the wheel concerned.
Stop as soon as it is safe to do so, avoiding any sudden movement
of the steering wheel and the brakes.
Repair or change the damaged wheel (punctured or very defl ated
tyre), and have the tyre pressure checked as soon as possible.
Sensor(s) not detected or faulty
This warning lamp is displayed in the instrument panel
accompanied by an alert message to identify the wheel or wheels
which are not detected or to indicate a fault in the system.
Contact a PEUGEOT dealer or a qualifi ed workshop to replace the
faulty sensor(s).
This message is also displayed when one of the wheels is away
from the vehicle (being repaired) or when one or more wheels
without a sensor are fi tted.
If your vehicle has a spare wheel, this does not have a sensor.
All repairs and changing of tyres on a wheel fi tted with this
system must be carried out by a PEUGEOT dealer or a qualifi ed
workshop.
If, when changing a tyre, you install a wheel which is not detected
by your vehicle (example: fi tting of snow tyres), you must have
the system reinitialised by a PEUGEOT dealer or a qualifi ed
workshop.
This system does not avoid the need to have the tyre pressures
checked regularly (refer to the "Identifi cation markings" section)
to ensure that the optimum dynamic performance of the vehicle is
maintained and prevent premature wear of the tyres, particularly in
arduous driving conditions (heavy load, high speed).
The tyre pressures must be checked cold, at least once a month.
Remember to also check the pressure of the spare wheel if your
vehicle has one.
The tyre under-infl ation detection system may experience
temporary interference due to electro-magnetic signals on a
frequency close to that used by the system.
