If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
Operating principleEach wheel (except for the emergency 
spare wheel) has a sensor in the infla-
tion valve which periodically measures 
the tyre pressure. The system informs 
the driver via the display 1 and on-
board computer  2 that the tyres are suf-
ficiently inflated and warns if they are 
underinflated or leaking. The warning 
light  4 
 on the instrument panel 
comes on to warn the driver if the pres-
sure is too low.
Resetting the standard level 
for the tyre pressures
This should be done:
–  when the standard tyre pressure  needs to be changed to adapt to 
usage conditions (empty, carrying a 
load, motorway driving, etc.);
–  after swapping wheels over;
–  after changing a wheel.
This function is an addi-
tional driving aid.
However, the function does 
not take the place of the 
driver. It cannot, therefore, under 
any circumstances replace the vig-
ilance or the responsibility of the 
driver.
Check the tyre pressures, including 
the emergency spare wheel, once a 
month.
TYRE PRESSURE MONITORING SYSTEM (1/4)
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.).
With the ignition on:
–  Make short presses on the control  3 
to select the tyre pressure display 
(see “On-board computer: settings” 
in Section 1);
–  press and hold (around 3 seconds)  the button  3 to launch the reset. A 
flashing tyre followed by the mes-
sage “Pressure ref Ongoing” indi-
cates that the request to learn the 
reference pressure has been taken 
into account;
–  reset can take several minutes of  driving.12

TYRE PRESSURE MONITORING SYSTEM (3/4)
“Check tyre pressure sensors”
The warning light 
 flashes for 
several seconds, then stays on, along 
with the message “Check tyre pressure 
sensors” and a missing wheel  B.
This message appears along with the 
© warning light.
This message appears when at least 
one wheel fitted on the vehicle does not 
have sensors (e.g. emergency spare 
wheel). In other cases, contact an au-
thorised dealer.
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, sensors, etc.).
Contact an authorised dealer to replace 
the tyres and to find out about avail-
able accessories compatible with the 
system: the use of any other accessory 
could affect the correct operation of the 
system or damage a sensor.
B
Changing a wheel
The system may take sev-
eral minutes depending on 
use for the new wheel po-
sitions and pressures to be recog-
nised; check the tyre pressures after 
all operations.

Interchangeability of wheelsIf you wish to swap the wheels around, 
please consult an approved dealer to 
reinitialise the system.
Each of the sensors incor-
porated in the valves 5  is 
dedicated to a single wheel: 
under no circumstances 
should you swap the wheels, with-
out resetting the system.
There is a risk of incorrect informa-
tion which could have serious con-
sequences.
