After each service, the service indi-
cator must be reset to zero.
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 dis-
tance recorder 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 that you
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 preserve the sealing of the air
conditioning compressor, operate
the air conditioning at least once a
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
excessive, air the passenger com-
partment by opening the windows
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
accordance with the vehicle's ser-
vicing schedule (see "Maintenance
and Warranty Guide").
Air circulation
Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning in the passenger com-
partment uses a number of sensors
(sunshine sensor, ambient tempera-
ture sensor...) that relieve you of the
need to make frequent adjustments
to the displayed temperature.
Take care not to obstruct the sun-
shine sensor, located on the dash-
board behind the instrument panel.

DIGITAL AIR CONDITIONING
The air conditioning system oper-
ates with the engine running.
1. Automatic comfort regulation
A press on this button,
confi rmed by the display of
the A/C warning lamp and
of AUTO on the screen, pro-
vides automatic control, at the tem-
perature selected, of all the following
5 functions:
- air fl ow,
- passenger compartment tempe- rature, left and right,
- air distribution,
- air conditioning,
- automatic air recirculation. For this facility to operate, it is rec-
ommended that all air vents are kept
open.
Using the
AUTO mode will prevent
the formation of mist inside the
vehicle in cold or humid weather.
When starting from cold, in order to
avoid a rush of cold air, the air fan at-
tains its optimum level progressively. 2. Adjustment of temperature
To display the desired temperature,
press button:
-
- to decrease the temperature,
- + to increase the temperature.
A setting around 21 will provide
an agreeable temperature level.
However, depending on your prefer-
ence, anything between 18 and 24
is quite normal.
For optimum comfort, it is recom-
mended to avoid a difference of set-
tings of more than than 3 between
right and left.
Actual temperatures experienced in
the passenger compartment are de-
pendent on external factors and for
this reason might not be identical to
those displayed.
On entering the vehicle, the inside
temperature may be much colder (or
hotter) than would be comfortable. It
serves no purpose to alter the tem-
perature displayed in an attempt to
attain your preference more rapidly.
The system operates automatically
to correct the difference in tempera-
ture as soon as possible.

Manual resumption of one or more
functions
It is possible to adjust each of the
functions 3 , 4 , 6 and 10 manually.
The display of the "AUTO" function
will then go off.

adjustment of passenger com-
partment temperatures (for the
front and rear passengers)

ton cancels all personal settings,
including the passenger's tem-
perature, and returns the system
to automatic operation.
