SYSTEM A (cntd.)
Resetting the standard level for the
tyre pressures
This should be done:
– after each reinflation or readjustment of the pressure of one of the tyres;
– when the standard tyre pressure needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after changing a wheel;
– after using the tyre inflation kit;
– after swapping a wheel (however, this practice is not recommended).
It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).2

Resetting procedure
With the ignition on:
– repeatedly press one of the but- tons 3 or 4 to select the “TIRES SET
TPW” function on the display 2;
– press and hold (around 3 seconds) button 3 or 4 to start initialisation.
The display of the message “SET
TPW LAUNCHED” for around five
seconds indicates that the reset re-
quest for the tyre pressure reference
value has been taken into account.
Reinitialisation is carried out after a few
minutes’ driving.
TYRE PRESSURE LOSS WARNING (3/7)
Display
The display 2 on the instrument panel
informs you of any tyre pressure faults
(flat tyre, punctured tyre, etc.).
“INFLATE TIRES AND SET TPW”
Warning light
comes on, along
with the message “INFLATE TIRES
AND SET TPW”. They indicate that at
least one tyre is flat or punctured.
In the event of a flat tyre, inflate the re-
levant tyre.
In the event of a puncture, change the
tyre or consult an authorised dealer.
Check and readjust the pressure of the
four tyres when cold, and launch the
reset of the tyre pressure reference
value. Warning light
goes out
after launching the reinitialisation of the
tyre pressure reference value.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.
