- The warning lamp comes on if the driver’s seat belt is not fastened
when the ignition is switched on
and between 0 and 20 km/h (ap-
prox. 12 mph).
- Above 20 km/h (approx. 12 mph), the warning lamp ﬂ ashes for ap-
proximately 120 seconds, ac-
companied by an audible signal.
It then remains on.

System which informs the driver
when the next service is due, in
accordance with the manufacturer’s
servicing schedule.
The point at which the service is due
is calculated from the last indicator
zero reset. It is determined by two
parameters:
- the distance travelled,
- the time elapsed since the last
service.

Maintenance indicator zero reset Engine oil level indicator
After each service, the maintenance
indicator must be reset to zero.
Your CITROËN technician resets the
indicator to zero after each service.
However, if you do your own servicing,
the procedure for resetting to zero is
as follows :

 switch off the ignition,

 press and hold the trip distance
recorder zero reset button,


switch on the ignition; the distance re-
corder display begins a countdown,

 when the display indicates "=0" ,
release the button; the spanner
disappears. System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is displayed for a
few seconds when the ignition is
switched on, after the service infor-
mation.
The level read will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 15 minutes.
Oil level correct
Oil level low
This is indicated by the ﬂ ashing of

"OIL" , accompanied by an audible
signal and a message on the multi-
function screen.
If the low oil level is conﬁ rmed by a
check using the dipstick, it is essen-
tial that the level is topped up to pre-
vent damage to the engine. Oil level gauge fault
This is indicated by the ﬂ ashing of

"OIL--" . Contact a CITROËN dealer.
Dipstick
Refer to the "Checks" section to lo-
cate the dipstick and the oil ﬁ ller cap
on your engine. There are 2 marks on
the dipstick:
- A = max; never ex-
ceed this level,
- B = min; top up the
level via the oil ﬁ ller
cap, using the type
of oil suited to your
engine.
Following this operation, if you wish
to disconnect the battery, lock the
vehicle and wait at least ﬁ ve minutes
for the zero reset to be taken into ac-
count.

Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows for a few moments, then close
them again.
The air conditioning operates by
using power from the engine. This
results in a slight increase in fuel
consumption.
Dust filter/Odour filter
(active carbon)
There is a ﬁ lter for excluding odours
and dust.
This ﬁ lter has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see "Maintenance
Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating efﬁ ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air
ﬂ ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

comfort in the passenger compart-
ment, the control should not remain
in position
0 (position 1 minimum ).

The heating/ventilation and manual
air conditioning systems can only
function with the engine running. This position is for excluding
disagreeable odours or emis-
sions coming from outside
the cabin. With a press on
control 2 , the entry of air from outside
is closed off, the lamp comes on.
This should be cancelled as soon as
possible to prevent misting and to al-
low fresh air into the cabin.
To deactivate air recirculation, press
again on control 2 , the warning lamp

lamp comes on.
It switches off automatically to avoid
excessive power consumption.
One press stops the demisting.
A further press starts it again.
If the engine is stopped before the
end of demisting, the operation will
resume the next time the engine is
started.
6 - Air conditioning
The air conditioning will only operate
when the engine is running.
Press on control 6 The warn-
ing lamp comes on.
For air conditioning, the air
blower control 3 must not be
on position "0" .
Air conditioning is obtained by mix-
ing the warm air with refrigerated air.
The temperature control 4 adjusts
the air conditioning provided the
control 6 is operational.

 When you enter the vehicle, the
temperature inside the vehicle
may be much colder (or warmer)
than a comfortable temperature.
There is no point in modifying
the displayed temperature to
try to attain the desired level of
comfort. The system operates
automatically to compensate this
temperature discrepancy as rap-
idly as possible.

 When starting the engine from
cold, in order to avoid distributing
too much cold air, the blower will
attain its optimum level gradually.
