TYRE UNDER-INFLATION
DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Under-infl ated tyre
The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver.
Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold.
The STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
or very defl ated tyre), and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
screen locating the wheel
or wheels which are not detected or
indicating a fault in the system.
Have the faulty sensor(s) checked by
a CITROËN dealer.
All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic perform-
ance of the vehicle is maintained
and prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to electro-mag-
netic signals on a frequency close
to that used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are fi tted.
The spare wheel is not fi tted with a
sensor.
