Instruments and controls
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.
EMISSIONS CONTROLS
EOBD (European On Board
Diagnosis) is a diagnostics
system which complies with,
among others, the standards
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before a
long journey.
concerning authorised emissions of:
-
-
-
CO (carbon monoxide),
HC (unburnt hydrocarbons),
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).
NOx (nitrous oxides) or particles,
detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
The driver is warned of any malfunction
of this emission control system by the
illumination of this specific warning lamp in
the instrument panel.
Driving with under-inflated tyres
increases fuel consumption.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN
dealer or a qualified workshop.
DETECTION
System which automatically checks the
pressures of the tyres while driving.
The tyre pressures for your vehicle can
be found on the tyre pressure label
(see the "Identification markings" section).
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
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.
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.
