Puncture
The STOP warning lamp comes on.
Stop as soon as it is safe to do so,
avoiding any sudden movement of the
steering wheel and the brakes.
Make a temporary repair to the tyre
using the puncture repair kit or by
fi tting the spare wheel.
Change the damaged wheel, and have
the tyre pressures checked as soon as
possible.
Sensor(s) fault or not detected
The Service warning lamp comes on.
When changing a wheel or in the
event of a sensor fault, the tyre
pressure is no longer monitored.
Contact a CITROËN dealer or a
qualifi ed workshop to replace the faulty
sensor(s).
All repairs and changing of tyres on a
wheel fi tted with this system must be
carried out by a CITROËN dealer or a
qualifi ed workshop.
If when changing a tyre, you fi t a
wheel not detected by your vehicle
(for example: fi tting snow tyres), you
must have the system reinitialised
by a CITROËN dealer or a qualifi ed
workshop.
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.
TYRE UNDER-INFLATION
DETECTION EMISSIONS CONTROLS
Deflated tyre
The Service warning lamp comes on.
Following a warning, the under-infl ation
of the tyre will not necessarily be
visible.
Check the tyre pressure as soon as
possible.
Refer to the "Changing a wheel"
section of chapter 7.
If the damaged wheel is replaced by
one without a sensor (for example,
the spare wheel), the message
is maintained to indicate that the
pressure of the wheel cannot be
monitored, so providing a reminder that
the damaged wheel with sensor must
be repaired. Sensors continuously monitor the tyre
pressures and trigger a warning in the
event of under-infl ation, a puncture or
a fault with a sensor. 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.
The driver is warned of any malfunction
of this emission control system by the
illumination of this specifi c 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 qualifi ed
workshop.
Any anomaly is indicated
by visual and audible
information and is
accompanied by a
message in the screen.
Good practice
This system does not avoid the need
to have the tyre pressures 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 heavy loads
and high speeds.
Observing the recommended tyre
pressures helps reduce the vehicle's
fuel consumption.
The system may temporarily be
disturbed by electro-magnetic
emissions on a frequency close to that
used by it.
