TYRE PRESSURE MONITORING SYSTEM (1/4)
If the vehicle is equipped with the func-
tion, this system monitors the tyre pres-
sure.
It should always be done after checking
the tyre pressure of all four tyres when
cold.
1
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).
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 on-board compu-
ter 1 that the tyres are sufficiently in-
flated and warns if they are underinfla-
With the ignition on:
– make short presses on the con-
trol 2 to select the tyre pressure
display (please refer to “On-board
Computer” in Section 1);
– press and hold (around three sec-
onds) the control 2 to launch initial-
isation. Flashing tyres followed by
the message “Pressure ref ongoing”
means that the request to learn the
reference pressures has been taken
into account;
ted or leaking. The warning light
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 (how-
ever this practice is not recom-
mended);
– reset can take several minutes of dri-
ving.
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 vi-
gilance or the responsibility of the
driver.
– after changing a wheel.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
