Maintenance indicator
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.
More than 620 miles (1 000 km)
remain before the next service is due
For 5 seconds after the ignition is
switched on, the spanner symboli-
sing the service operations comes on.
The distance recorder display line
indicates the distance remaining
before the next service is due.

Example: 1 900 miles remain before
the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates: 5 seconds after the ignition is switched
on,
the spanner is switched off ; the
distance recorder resumes its normal
operation. The display then indicates
the total and trip distances.
Less than 620 miles (1 000 km)
remain before the next service is due

Example: 500 miles remain before
the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates:
5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation. The
spanner remains on to indicate that
a service must be carried out soon. Service overdue
For 5 seconds after the ignition is
switched on,
the spanner ﬂ ashes
to indicate that the service must be
carried out as soon as possible.

Example: the service is overdue by
300 miles.
For 5 seconds after the ignition is
switched on, the display indicates:
5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation. The
spanner remains lit .
The distance remaining may be
weighted by the time factor, depen-
ding on the driver's driving habits.
Therefore, the spanner may also
come on if you have exceeded the
two year service interval.

Maintenance indicator zero reset
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 servi-
cing, 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.
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. Engine oil level indicator
System which informs the driver
whether the engine oil level is cor-
rect or not.
This information is indicated 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 displaying of the
message "Oil level incorrect".
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 displaying of
the message "Oil level measure-
ment invalid". Consult a CITROËN
dealer.

Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air ﬂ ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (exterior temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.

 Please do not block the sunshine
sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and
leave all of the vents open, optimum
comfort will be maintained and humid-
ity and condensation will be removed
regardless of the exterior climatic con-
ditions.
The temperature in the passenger
compartment can only be lower than
the exterior temperature if the air
conditioning is on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the in-
terior temperature is very high, venti-
late the passenger compartment with
the windows open for a few minutes,
then close the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses the engine
power during its operation. As a result,
the fuel consumption of the vehicle in-
creases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high tem-
peratures), switching off the air condi-
tioning permits the recovery of engine
power and therefore increases the
towing capacity.
Air inlet
Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spray-
ing at the air inlet. Air circulation
Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the ﬂ aps in the boot.
The front and rear vents are ﬁ tted
with thumbwheels to adjust the air
ﬂ ow and direction. We recommend
that you leave all of the vents open.
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
and Warranty Guide").

 Fetch the vehicle chock located
in the boot.

 Immobilise the vehicle by placing
the chock at the front or at the
rear of one of the rear wheels.

 Open the lower compartment of
the centre armrest by pulling it.

 Ensure that the cup holder B is
folded away.

 Remove the rubber mat covering
the base of the armrest. This strap does not permit
application of the parking
brake.
To re-engage the electric parking
brake (after rectifying the malfunc-
tion or battery failure), give a long
pull on the control A until the parking
brake warning lamp (!) ﬂ ashes on the
instrument panel then give a second
long pull until this warning lamp is lit
permanently.
The time required for the subse-
quent application may be longer
than during normal operation.
It is essential that the ignition is
not switched on until the parking
brake has re-engaged (ﬂ ashing of
the warning lamp (!) on the instru-
ment panel then warning lamp lit
permanently) to avoid damage to
the parking brake.
Take care not to allow moisture or
dust in the proximity of the diagnostic
socket D which is essential for the
maintenance of your vehicle.

 Release the strap from its loca-
tion C .

 Pull the strap to release the
brake. A loud knock conﬁ rms the
release of the brake.

 Take care to put the strap
back in its location C correctly.
Otherwise, it will no longer be
possible to apply the brake.
Consult a CITROËN dealer.

 Put the rubber mat back in place
on the base of the armrest.

 Remove and stow the chock.

pump. HDi 138 and HDi 173 engines

 Unclip the protective cover
to gain access to the priming
pump.
Priming the fuel circuit
In the event of running out of fuel:

 after ﬁ lling (minimum 5 litres)
and removing the protective
cover, operate the manual prim-
ing pump, until some resistance
is felt,

 operate the starter motor while
depressing the accelerator pedal
slightly until the engine starts. HDi engines are the result
of advanced technology.
All maintenance and repairs require
special qualiﬁ cations which only a
CITROËN dealer can guarantee.
V6 HDi 208 engine with electric
pump
In the event of running out of fuel:

 after adding fuel, turn the ignition
key to position M , wait for a few
seconds,

 operate the starter motor until
the engine starts.
If the engine fails to start after sev-
eral attempts, contact a CITROËN
dealer.
If the engine fails to start at the ﬁ rst
attempt, wait ﬁ fteen seconds before
trying again.
If the engine fails to start after a
few attempts, operate the priming
pump again and then try to start the
engine.
When the engine is idling, acceler-
ate slightly to complete the bleeding
of the circuit.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signiﬁ cantly, have the
corresponding system checked by a
CITROËN dealer.
Oil level Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
Oil speciﬁ cation
The oil must correspond to your en-
gine and conform to the manufactur-
er’s recommendations. Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.
This ﬂ uid must be changed regularly.
Fluid which has been used exces-
sively may cause a loss of braking
efﬁ ciency.
Fluid speciﬁ cation
The brake ﬂ uid must conform to the
manufacturer’s recommendations
and fulﬁ l the DOT4 standards.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (1,000 km).
Check this level also between each
scheduled service and before long
journeys. The brake ﬂ uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited. Power steering fluid or power
steering and suspension
fluid level
This ﬂ uid must be topped up
by a CITROËN dealer.
Dipstick
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 en-
gine.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, par-
ticularly in summer and
winter.
When carrying out work on the bat-
tery, refer to the "Practical information" section for details of the precautions
to be taken before disconnecting the
battery and following its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" paragraph).
A clogged cabin ﬁ lter may have an
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Oil filter
Replace the oil ﬁ lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
converter, this ﬁ lter makes an ac-
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally
notice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a mes-
sage appears on the instrument
panel display, accompanied by an
audible signal and lighting of the
service warning lamp.
This alert tells you that the particle
ﬁ lter is starting to ﬁ ll up (in conditions
of urban driving of exceptionally long
duration: low speeds, trafﬁ c jams
etc.)
To regenerate the ﬁ lter, it is advised
to drive as soon as possible, when
trafﬁ c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least ﬁ ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the Maintenance and
Warranty Guide for details of the
replacement interval for this compo-
nent.
