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.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. 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 (see
the "Identification 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).
Other wise, add 0.3 bar to the values
indicated on the label.
Driving with under-inflated tyres
increases fuel consumption.
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.

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 tyre or
tyres concerned is reinflated, repaired
or replaced.
The spare wheel (space-saver type or a
steel rim) does not have a sensor.
Under-inflation alert
The aler t is given by the fixed illumination
of this warning lamp, accompanied by
an audible signal, and depending on
equipment, the display of a message.
In the event of a problem on one of the tyres,
the symbol or the message appears, according
to equipment, to identify it.

Operating fault
The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by
the illumination of the service warning lamp
indicates a fault with the system.
In this case, monitoring of the tyre pressures is
not assured.
This alert is also displayed when one or more
wheels is not fitted with a sensor (for example,
a space-saver or steel spare wheel).
Go to a CITROËN dealer or a qualified
workshop
to have the system checked
or, following the repair of a puncture, to
have the original wheel, equipped with a
sensor, refitted.
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 after changing a tyre, a wheel is not
detected by your vehicle (fitting snow
tyres for example), you must have the
system reinitialised by a CITROËN
dealer or a qualified workshop.

DSC/ASR
The DSC and ASR systems offer increased
safety in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep the DSC and ASR systems
activated in all conditions, and particularly
in difficult conditions.
The correct operation of these systems
depends on observation of the
manufacturer's recommendations regarding
as much the wheels (tyres and rims),
braking and electronic components as the
assembly and repair procedures used by
CITROËN dealers.To benefit in full from the effectiveness
of the DSC and ASR systems in wintry
conditions, the vehicle must be fitted with
four snow tyres, allowing the the vehicle to
retain neutral behaviour on the road.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
