If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
Operating principle
Each 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.
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.

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 (how-
ever this practice is not recom-
mended);
– after changing a wheel.
This function is an additio-
nal 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.
