TYRE UNDER-INFLATION
DETECTION
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as
the vehicle is moving.
A pressure sensor is located in the
valve of a each tyres (except the spare
wheel).
The system triggers an alert if a drop
in pressure is detected in one or more
tyres.
The tyre under-infl ation detection sys-
tem is an aid to driving which does not
replace the need for the driver to be
vigilant or to drive responsibly.
This system does not avoid the
need to check the tyre pressures
regularly (including the spare
wheel) and before a long jour-
ney.
Driving with under-infl ated tyres
adversely affects road holding,
extends braking distances and
causes premature tyre wear,
particularly under arduous con-
ditions (vehicle loaded, high
speed, long journey).
Driving with under-infl ated tyres
increases fuel consumption.
The tyre pressures for your vehi-
cle can be found on the tyre pres-
sure label (see the "Identifi cation
markings" section).
The tyre pressures must be
checked when the tyres cold
(vehicle stopped for 1 hour or
after driving for less then 6 miles
(10 km) at moderate speed).
Otherwise, add 0.3 bar to the val-
ues indicated on the label.

cates a fault with the system.
Operating fault
The alert is given by the fi xed il-
lumination of this warning lamp,
accompanied by an audible sig-
nal, and depending on equip-
ment, the display of a message.
Under-inflation alert
The alert is maintained until the
tyre or tyres concerned is rein-
fl ated or repaired.
The loss of pressure detected
does not always lead to visible
deformation of the tyre. Do not
rely on just a visual check.
This alert is also displayed when
one or more wheels is not fi tted
with a sensor.
In the event of a problem on one of
the tyres, the symbol or the message
appears, according to equipment, to
identify it.
Reduce speed, avoid sudden steer-
ing movements or harsh brake ap-
plications.
Stop as soon as it is safe to do so.
In the event of a puncture, use the
temporary puncture repair kit or the
spare wheel (according to equip-
ment),
or
if you have a compressor, the one in
the temporary puncture repair kit for
example, check the four tyre pres-
sures when cold,
or
if it is not possible to check the tyre
pressures at the time, drive care-
fully at reduced speed. In this case, monitoring of the tyre pres-
sures is not assured.
Have the system checked by a
CITROËN dealer or a qualifi ed work-
shop.
