TYRE PRESSURE LOSS WARNING (1/3)
When fitted to the vehicle, this system
notifies the driver if one or more tyres
lose pressure.
Operating principle
Each wheel has a sensor in the inflation
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, punctu-
red tyre, etc.).
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 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.).
This function is an additio-
nal driving aid.
However, the function is
not intended to replace the
driver. It cannot, therefore, under
any circum-stances replace the vig-
ilance or the responsibility of the
driver.
Check the tyre pressures once a
month.

Note
The standard tyre pressure cannot be
less than that recommended and indi-
cated on the door frame.
Display
Check tyre pressure
The warning light
comes on (not
flashing).
This indicates 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.
Puncture
Warning light
comes on steady,
accompanied by a beep and warning
light
®They indicate that at least one wheel
is punctured or severely underinfla-
ted. Replace it or contact an approved
dealer if it is punctured. Top up the tyre
pressure if the wheel is deflated.
Check tyre sensors
The warning light
flashes for
several seconds, then stays on, along
with the warning light
©.
They indicate that at least one wheel is
not fitted with sensors. In other cases,
contact an authorised dealer.
TYRE PRESSURE LOSS WARNING (2/3)

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 warning light 5 on the dis-
play 2;
– press and hold (around 3 seconds) button 3 or 4 to start initialisation.
When the «SET» warning light
flashes for around five seconds, this
indicates 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.
