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.
