Instruments and controls
EMISSIONS CONTROLS
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrous oxides) or particles, detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
TYRE UNDER-INFLATION DETECTION
System which automatically checks the
pressures of the tyres while driving.
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. 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 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
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres. 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 values
indicated on the label.
The tyre pressures for your vehicle can be
found on the tyre pressure label.
The driver is warned of any
malfunction of this emission
control system by the illumination
of this specific warning lamp in
the instrument panel.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN
dealer or a qualified workshop.
Refer to the "Technical data -
Identification markings" section.

Levels and checks
Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation / Regeneration Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles, ...) so as to avoid
any risk of fire.
Particle filter system (Diesel)
An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
Operation
This filter, fitted to the exhaust system,
accumulates particles of soot. The engine
management unit controls the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature - which does not affect the
operation of the vehicle or the environment. After prolonged idling or driving at very
low speeds, you may occasionally
notice water vapour being emitted from the
exhaust when accelerating. This is of no
consequence to the running of the vehicle or
to the environment. To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least
40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)

TECHNICAL DATA
Diesel engines
Quality of the fuel used for Diesel engines
The Diesel engines are perfectly compatible with biofuels which conform \
to current and future European standards (Diesel fuel which
complies with standard EN 590 mixed with a biofuel which complies with s\
tandard EN 14214) available at the pumps (containing up to
5% Fatty Acid Methyl Ester).
The B30 biofuel can be used in certain Diesel engines; however, this use is subject to strict application of the special servicing con\
ditions
given in the maintenance and warranty guide. Contact a CITROËN dealer\
or a qualified workshop.
The use of any other type of (bio)fuel (vegetable or animal oils, pur\
e or diluted, domestic fuel...) is strictly prohibited (risk of damage to the
engine and fuel system). ENGINES AND GEARBOXES
