MONITORING













Service indicator zero reset















Engine oil level indicator

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 correct
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 30 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
or a qualifi ed workshop.

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 (risk
of engine damage),

- B
= min; top up the
level via the oil fi ller,
using the type of oil
suited to your en-
gine.


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 sunlight
the interior temperature is excessive,
air the passenger compartment by
opening the windows for a few mo-
ments, 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's servicing
schedule (see the servicing booklet).


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 thumb wheels 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.

- passenger compartment tem-
perature, 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 ve-

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.

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.
