Instruments and controls
EMISSIONS CONTROLS
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 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. EOBD (European On Board
Diagnosis) is a diagnostics
system which complies with,
among others, the standards
DETECTION
Sensors continuously monitor the tyre
pressures and trigger a warning in the event
of under-inflation, a puncture or a fault with
a sensor.
Any anomaly is indicated by visual and
audible information and is accompanied by a
message in the screen.
Deflated tyre
The Service warning lamp comes on.
Following a warning, the under-inflation of
the tyre will not necessarily be visible.
Check the tyre pressure as soon as
possible.
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 fitting the spare
wheel.
Change the damaged wheel, and have the
tyre pressures checked 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.
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 qualified workshop to replace the faulty
sensor(s).
