Puncture
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged (punctured or
very defl ated) tyre, and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected
Under-infl ation detection is absent
from one (or several) tyre(s). Contact a
CITROËN dealer to replace the faulty
sensor(s).
This message is also displayed when
one of the tyres is away from the
vehicle (being repaired) or when a
wheel without a sensor is fi tted.
All repairs and changing of tyres on a
wheel fi tted with this system must be
carried out by a CITROËN dealer.
The tyre under-infl ation detection
system is a driving aid which does
not take the place of vigilance or the
responsibility of the driver.
This system does not remove the need
to have the tyre pressure checked
regularly (including the spare wheel), to
ensure that the dynamic performance
of the vehicle remains at its best and
to avoid premature wear of the tyres,
in particular in the case of arduous
driving (heavy load, high speed).
The system may temporarily be
disturbed by radio broadcasts on a
frequency close to it.
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrogen oxides) or particles,
detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
Therefore, the driver is warned of any
malfunction of this emission control
system by the lighting of this specifi c
warning light on the instrument panel.
There is a risk of damage to the
catalytic converter. Have it checked by
a CITROËN dealer.
Flat tyre
Check the tyre pressure as soon as
possible.
Refer to the "Changing a wheel"
section of chapter 7.
If the damaged tyre is temporarily
stored inside the vehicle, it will again
emit this message to remind you of the
necessity of having it repaired. This will
prevent another warning of the same
type being displayed.
Sensors check the tyre pressure during
driving (speed higher than 12 mph
[20 km/h]) and trigger a warning in the
event of a malfunction or puncture.
EOBD (European On Board
Diagnosis) is a diagnostics
system which complies with,
among others, the standards
concerning authorised
emissions of:
Any anomaly detected
(fl at or punctured tyre,
malfunction of a sensor)
is indicated by visual and
audible information and
is accompanied by a message on the
display.
