Air conditioning
We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following functions:
a i r fl o w , t e m p e r a t u r e i n t h e p a s s e n -
ger compartment and air distribu-
tion, by means of various sensors
(ambient temperature, sunshine).
This eliminates any need for you to
change your settings other than the
temperature value displayed.
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 condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the
i n t e r i o r t e m p e r a t u r e i s v e r y h i g h , fi r s t
ventilate the passenger compartment
with the windows open for a few min-
utes, 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.

On sloping ground: immobilise
the vehicle by placing the chocks
(if your vehicle has them) in front
or behind the two front wheels,
against the slope
On level ground: immobilise the vehicle by placing the chocks
(if your vehicle has them) in
front and behind one of the front
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
l a m p i s o n fi x e d .
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

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 correctly. Otherwise,
it will no longer be possible to ap-
ply the brake. Consult a CITROËN
dealer.
Put the rubber mat back in place
on the base of the armrest.

In the event of a malfunction with
the system, the "ECO OFF" switch
w a r n i n g l a m p fl a s h e s t h e n c o m e s

Have it checked by a CITROËN
dealer.

Maintenance
This system requires a battery with
a s p e c i a l s p e c i fi c a t i o n a n d t e c h n o l -
ogy (reference numbers available
from CITROËN dealers).
Fitting a battery not listed by
CITROËN introduces the risk of
malfunction of the system.

Check this level also between each
scheduled service and before long

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your en-
gine.
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 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" section).

Complementary to the catalytic

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 recom-
mended by CITROËN or
products of equivalent quality
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 .
