The tyre under-inflation detection
system is an aid to driving which does
not replace the need for vigilance on
the part of the driver.
Under-inflation detection
System which continuously and automatically checks the pressures of the four tyres after switching on the ignition.
A pressure sensor is located in the valve of each tyre (except the spare wheel).
The system triggers an alert if a drop in pressure is detected in one or more tyres, compared to the reference pressure registered in the system. This
reference pressure must be reinitialised every time the tyre pressures are adjusted or a wheel changed.
The system operates on condition that the sensor identifiers have first been memorised in the system by a CITROËN dealer or a qualified workshop.
You can memorise two sets of tyres (e.g. wheels with "standard" tyres and wheels with "winter" tyres).Driving with under-inflated tyres
increases fuel consumption.This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre pressures for your vehicle can
be found on the tyre pressure label.
For more information on Identification
markings
, refer to the corresponding
section.
The tyre pressures must be checked
when the tyres are cold (vehicle
stopped for 1 hour or after driving for
less then 6 miles (10 km) at moderate
speed). Other wise, add 0.3 bar to the
values indicated on the label.

top as soon as it is safe to do so. The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check. The alert is maintained until the
reference pressure is reinitialised after
the inflation, repair or replacement of
the tyres concerned. In the event of
the repair or replacement of tyres, the
sensor identifiers must be registered in
the system by a CITROËN dealer or a
qualified workshop.
The spare wheel does not have
a sensor, so there is no need to
reinitialise the system for driving with
the spare wheel fitted.

temporary puncture repair kit, for example),

pressures immediately, drive carefully at

n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
Reinitialising the reference
pressure
Before reinitialising the system, ensure
that the pressures in the four tyres are
suitable for the conditions of use of the
vehicle and are as specified on the tyre
pressure label.
The under-inflation detection system
cannot warn of an incorrect pressure at
the time of reinitialisation.
The system must be reinitialised after any
adjustment of tyre pressures and after
changing one or more wheels.

The reinitialisation instruction is entered in
the screen menu, with the ignition in the "ON"
position and the vehicle stationary.
F Press several times on the INFO button,
located below the instrument panel to the
left of the steering wheel.

2/3 or 3/3 depending on the
instrument panel) .
F

P
ress and hold the INFO button for at least
3 seconds to reinitialise the under-inflation
detection system.
Reinitialisation of the system is confirmed
by the flashing of the warning lamp in the
instrument panel. The under-inflation alert is only reliable
if the system has been reinitialised
with the four tyre pressures correctly
adjusted.
Operating fault
The flashing and then fixed illumination of the
under-inflation warning lamp accompanied by
the display of a message indicates a fault with
the system.
In this case, monitoring of the tyre pressures is
not assured.
This alert is also displayed if:
-

a
t least one wheel is not fitted with a
sensor (spare wheel in use),
-

a w
ireless device operating on the same
frequency is close to the vehicle,
-

t
here are accumulations of snow or ice in
the wings or wheels,
-

t
he state of charge of the tyre pressure
monitoring system battery is too low,
-

t
he wheel sensor identifiers have not been
memorised in the system by a CITROËN
dealer or a qualified workshop. Any tyre repair or replacement on a
wheel fitted with this system must be
carried out by a CITROËN dealer or a
qualified workshop.
If you fit the second set of tyres
memorised in the system, a fault will
be signalled until the second set is
selected in the configuration menu. Go to a CITROËN dealer or a qualified
workshop to have the system checked
or, after a puncture, to have the original
wheel, equipped with a sensor, refitted.

Managing sets of tyres
If you have had a second set of tyres registered
by a CITROËN dealer or a qualified workshop,
every time you change the set of tyres (fitting
a set of winter tyres, for example), you must
select the set you have just fitted in the
configuration menu.After fitting the new set of tyres, you
should check and adjust the tyre
pressures to the values specified on the
tyre pressure label.
For more information on Identification
markings and in particular the
tyre pressure label, refer to the
corresponding section. Selection of the other set of tyres is done via
the menu screen, with the ignition on and the
vehicle stationary.
F

P

select the menu for managing sets of tyres
(located in menu 3/3) .
F Press and hold the INFO button for at least
3 seconds to change successively from
set of tyres 1 to set of tyres 2 or the other
way round. The system automatically reinitialises
the reference pressure based on the
pressure in the new set (the under-
inflation detection warning lamp flashes
during the operation).
