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:
air fl ow, temperature in the passen-
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
interior temperature is very high, fi rst
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
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 must be changed in line
with the vehicle's servicing schedule
(see: "Maintenance and Warranty
Guide").

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 manufac-
turer'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 regular-
ly. 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 meet the DOT4 standard.
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.
Check this level also between each
scheduled service and before long
journeys.
Take care when doing anything un-
der the bonnet, as some parts of the
engine can be extremely hot (risk of
burns). 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 reli-
ability of the engine and emis-
sion 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 exceed
this level,
- B = min; top up the
level via the oil fi ller
cap, using the type
of oil suited to your
engine.
