The maintenance indicator informs you when the next service is due, in conformity with the servicing pro-gramme detailed in the vehicle’s Maintenance Guide. This informa-tion is determined depending on two parameters: the mileage travel-led and the time elapsed since the previous service.
Operation
When the ignition is switched on and for several seconds afterwards, the maintenance spanner symbol appears; the total mileage recorder shows how many miles remain to be travelled before the next service is due (in thousands and hundreds of miles).
Functioning if the distance to the next service is less than 600 miles
Each time the ignition is switched o n , a n d f o r fi v e s e c o n d s , t h e m a i n -tenance symbol and the mileage will fl a s h .
For example: you have the following distance left to travel before the next service: 900 km.

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 i n f r o n t ) w i l l fl a s h .
For example: the preset service dis-tance has been exceeded by 300 km. Your vehicle must be serviced as soon as possible.
A few seconds after you have swit-ched on the ignition, the total mi-leage recorder returns to its normal operation and the maintenance symbol remains illuminated.
Resetting the mileage indicator to zero
Your CITROËN dealer performs this operation after each service. Howe-ver, if you carry out the servicing yourself, the procedure for resetting to zero is as follows:
- Switch off the ignition, then place the key on position S, steering lock.
- Press control 1 and keep it pressed.
- Switch on the ignition.
- Keep control 1 pressed until the zero appears and the maintenance symbol disappears.
- Switch off the ignition.
Maintenance intervals
If your vehicle is used in particularly harsh conditions, it is necessary to select the maintenance schedules for "special operating conditions" (see the Maintenance Guide) which consist of more frequent services.

VENTILATION
Air intake
Make sure that the exterior air inlet grille at the base of the windscreen is clean (free of dead leaves, snow etc.).
If washing the vehicle with a high pressure jet, take care to avoid tar-geting close to the air inlet.
Air vents
The air vents have grilles for direct- i n g t h e fl o w o f a i r ( u p / d o w n , r i g h t / left) with controls for adjusting the volume of air.
Air circulation
Optimal comfort is obtained by a good distribution of air in the front and the rear of the passenger com-partment.
T o e n s u r e e f fi c i e n t o p e r a t i o n , t a k e care not to obstruct the air outlets located under the front seats.

At any time of year, the air condition-
ing is useful for removing air humidity
and misting.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If you are towing a heavy trailer or if
outside temperatures are very high,
the air conditioning may be tempo-
rarily interrupted in favour of engine
cooling.
Sensor
The automatic air conditioning inside the passenger compartment makes use of the sunlight sensor, which is located on the dashboard behind the instrument panel.
Take care not to obstruct it.
Water arising from condensation in
the air conditioning is allowed to drain
out through an aperture provided for
this purpose; a pool of water may
thus form beneath the vehicle when
stationary.
You are recommended to have the
air conditioning system checked on
a regular basis (see Maintenance
Guide).
The air conditioning uses energy
from the engine to operate. This re-
sults in extra fuel consumption
