Ty r e u n d e r - i nfl ation 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.
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).

Driving with under-inflated tyres
increases fuel consumption.
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.


The tyre under-inflation detection system is
an aid to driving which does not replace the
need for the driver to be vigilant or to drive
responsibly.

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.



Reduce speed, avoid sudden steering
movements or harsh brake applications.


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 equipment),
or


if you have a compressor, the one in the
temporary puncture repair kit for example,
check the four tyre pressures when cold,
or


if it is not possible to check the tyre
pressures at the time, drive carefully at
reduced speed.

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.


The loss of pressure detected does not
always lead to visible deformation of the
tyre. Do not rely on just a visual check.


Operating fault


The flashing and then fixed
illumination of the under-inflation
warning lamp accompanied by the
illumination of the "ser vice" warning
lamp indicates a fault with the system.

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.
In this case, monitoring of the tyre pressures is
not assured.

185Safety

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.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
The correct operation of these systems
depends on obser vation 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.
