TYRE PRESSURE LOSS WARNING (1/3)
1
When fitted to the vehicle, this system
notifies the driver if one or more tyres
lose pressure.
Operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure while driving.
Warning light
1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punc-
tured tyre, etc.).
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.
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 a wheel (however this practice is not recommended);
– after changing a wheel.
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.).

Note:
The standard tyre pressure cannot be
less than that recommended and indi-
cated on the door frame.
Display
Display 2 on the instrument panel in-
forms you of any tyre pressure faults
(flat tyre, punctured tyre, etc.).
“CHECK TYRE PRESSURES”
Warning light
comes on, along
with the message “CHECK TYRE
PRESSURES”.
These indicate that at least one tyre is
flat.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light
goes off after a
few minutes’ driving.
“TYRE PUNCTURE”
The warning light
comes on
steady, accompanied by the message
“TYRE PUNCTURE” and a beep.
This message appears along with the
® warning light.
They indicate that at least one wheel
is punctured or severely underinflated.
Replace it or contact an approved
dealer if it is punctured. Top up the tyre
pressure if the wheel is deflated.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow.
Resetting procedure
With the ignition on:
– repeatedly press button 3 or 4 to
select the “TYRE PRESSURE
ACQUISITION” function on the dis-
play 2;
– press and hold (around 3 sec- onds) button 3 or 4 to start initiali-
sation. Display of the message “TP
ACQUISTION LAUNCHED” indi-
cates that the reset request for the
tyre pressure reference value has
been taken into account.
Reinitialisation is carried out after a few
minutes’ driving.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.
