34EMISSIOnS cOntrOLS
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards on emissions
limits of:
-
CO (carbon monoxide),
-
HC (unburnt hydrocarbons),
-
NOx (nitrogen oxides), detected by
oxygen sensors placed downstream of
the catalytic converters,
-
particles.

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 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 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.
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 emissions
control system by the illumination
of this warning lamp in the
instrument panel.
If this warning lamp comes on, have it
checked by a CITROËN dealer or a qualified
workshop.
To locate it, refer to the "Technical
data
- Identification markings" section.
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).
