MAINTENANCE INDICATOR
It tells you when the next service is due , in conformity with the maintenance schedule in the Mainten ance guide.
This information is calculated as a function of two parameters: the mileage covered , and the time elapsed since
the last service.
Functioning
From switching on the ignition and
for a few seconds, the spanner
symbol for maintenance lights
up ; the instrument panel tells you
how many miles remain before the
next service.
For example: you have the
following distance left to travel
before the next service:
Functioning if the distance to the
next service is less than 1 000 km
(approx. 600 miles)
Each time the ignition is switched
on, and for ive seconds, the main -
tenance symbol and the mileage will
lash.
Example: before the next service
there remain: 500 km (approx.
300 miles). When you switch on the
ignition and for 5 seconds after that,
the instrument panel indicates: Functioning if the service
interval is exceeded
Each time the ignition is switched
on, the maintenance symbol and
the extra mileage travelled (with a
minus in front) will lash.
For example:
the preset service
distance has been exceeded by
300 km (approx. 10 miles). Your
vehicle must be serviced as soon
as possible.
A few seconds after that, the engine
oil level indicator is displayed, then
the total mileage recorder resumes
its normal role. The instrument
panel shows you the total and trip
mileage counters. A few seconds after that, the en
-
gine oil level indicator is displayed,
then the total mileage recorder
resumes its normal role and the
maintenance symbol remains lit
up.
It informs you that a service is
imminently due. The instrument
panel gives you the total and trip
mileages. A few seconds after you have
switched on the ignition, the
total mileage recorder returns
to its normal operation and
the
maintenance symbol remains
illuminated.

Maintenance intervals
If your vehicle is used in particularly harsh conditions, it is ne
cessary to select the maintenance schedules for
“special operating conditions” (see the Maintenance Guide) which consist of more frequent services.
Note: the maintenance spanner will come on, and the display will read
‘’0’’ if the maximum length of time between services is attained be fore the
mileage limit is reached.
Resetting the maintenance indicator to zero

you intend to service the vehicle yourself, the procedure for reset ting the
maintenance indicator is as follows:
- Switch off the ignition.
- Press and hold down button 1.
- Switch on the ignition.
- The distance remaining until the next service lashes.
- Keep button 1 pressed until the display shows “=0” and the maintenance

Complementary to the catalytic converter, this ilter makes an active
contribution to the preservation of air quality
by retaining the unburnt pollutant particles. Black exhaust fu mes are thus no longer emitted.
Clogging of the particle ilter
If there is risk of clogging, a message appears on the multifun ction display, accompanied by a sound signal and
lighting of the SERVICE warning lamp.
This alert tells you that the particle ilter is starting to ill up (in conditions of urban driving of exceptionally long
duration: low speeds, trafic jams etc.)
To regenerate the ilter, it is advised to drive as soon as possi ble, when trafic conditions permit, at a speed of
60 km/h (around 40 mph) or more for at least ive minutes (until the alert message disappears).
If this alert persists, consult a CITROËN dealer.
Observation: After prolonged idling or driving at very low speeds, you may occa sionally notice water vapour being
emitted from the exhaust when accelerating. This is of no conse quence to the running of the vehicle or to the
environment.
