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-
t i o n s : a i r fl o w , t e m p e r a t u r e i n t h e
passenger compartment and air
distribution, by means of various
sensors (ambient temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.
Take care not to cover the sun-
shine 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 humidity and
condensation will be removed regard-
less of the exterior climatic conditions.
The temperature in the passenger
compartment can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air con-
ditioning must be used with the win-
dows closed. If the vehicle has been
parked in the sun for a long period
and the interior temperature is very
h i g h , fi r s t v e n t i l a t e t h e p a s s e n g e r
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 engine power
during its operation. As a result, the fuel
consumption of the vehicle increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high
temperatures), switching off the air
conditioning saves engine power
and improves 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 spraying
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
t h e fl a p s i n t h e b o o t .
T h e f r o n t a n d r e a r v e n t s a r e fi t t e d
with thumbwheels to adjust the air
fl o w a n d d i r e c t i o n . W e r e c o m m e n d
that you leave all of the vents open.

D R I V I N G
Immobilise the vehicle by plac-
ing a 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 park-
i n g b r a k e w a r n i n g l a m p ( ! ) fl a s h e s
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
b r a k e h a s r e - e n g a g e d ( fl a s h i n g o f
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 diagnos-
tic 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
b r a k e . A l o u d k n o c k c o n fi r m s t h e
release of the brake.
Take care to put the strap
back in its location C correct-
ly. 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.

RUNNING OUT OF FUEL (DIESEL)
HDi 110 engine
Unclip the protective cover to gain
access to the priming pump. HDi 140 and HDi 163 engines
Unclip the protective cover to gain
access to the priming pump.
Priming the fuel system
In the event of running out of fuel:
a f t e r fi l l i n g ( m i n i m u m 5 l i t r e s )
and removing the protective cov-
er, operate the manual priming
pump, until some resistance is
felt,
operate the starter motor while
depressing the accelerator pedal
slightly until the engine starts. HDi engines make use of ad-
vanced technology.
All maintenance and repairs re-
q u i r e s p e c i a l q u a l i fi c a t i o n s w h i c h
only a CITROËN dealer can guar-
antee.
V6 HDi 240 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 several
attempts, contact a CITROËN dealer.

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.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Warranty and Maintenance
Record 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 cor-
rectly tightened, particularly
in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Warranty and
Maintenance Record 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 passenger compartment

odours.
Oil filter

the engine oil is changed. Particle filter system (Diesel)
Complementary to the catalytic
c o n v e r t e r , t h i s fi l t e r m a k e s a n a c -
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 no-
tice 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

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles used in town, over
short distances. It may be
necessary to have the condition of
the brakes checked, even between
vehicle services.
Unless there is a leak in the circuit, a
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer.
Only use products recommended
by CITROËN or products of equiv-
a l e n t q u a l i t y a n d s p e c i fi c a t i o n s .
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
f e r s v e r y s p e c i fi c p r o d u c t s .
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly
prohibited .
Refer to the Maintenance and
Warranty Guide for the details of the
level checking interval for this com-
ponent.
