of a problem in one
of the systems which
does not have a spe-
cifi c warning lamp.
It is accompanied by a message on
the multifunction screen.
The warning lamp comes on tempo-
rarily in the case of minor faults.
In the case of major faults, the warning
lamp remains on until the operating
fault is rectifi ed. Contact a CITROËN
dealer as soon as possible. Braking
If this comes on, it indicates
the occurrence of a fault in
one of the braking systems:
- signifi cant drop in the fl uid level in the circuit,
-
electronic brake force distribution
(EBFD) faulty (simultaneous lighting
of the ABS warning lamp),
Stop the vehicle as soon as it is safe
to do so.
Contact a CITROËN dealer.
Dynamic stability control
(ESP/ASR)
The ESP/ASR system is put
into service automatically
when the vehicle is started.
Unless the system has been de-
activated, if this warning lamp and
the indicator lamp on the button
come on continuously, this indi-
cates the occurrence of a fault in the
ESP/ASR system or in the hill start
assistance. Engine autodiagnostics system
If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
If it fl ashes, it indicates the occur-
rence of a fault in the emission control
system.
Central alert
- punctured wheel,
- braking,
- coolant temperature,
Stop the vehicle as soon as it is safe
to do so.
Contact a CITROËN dealer.
Anti-lock braking system (ABS) If this comes on, it indicates
the occurrence of a fault in
the anti-lock braking system.
However, this does not prevent op-
eration of the vehicle’s servo-assisted
braking system.

Air conditioning
To ensure that your system operates
correctly, it is recommended to 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 keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every 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 windows
closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
ventilate the passenger compartment
by opening the windows for a few
moments, 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 servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air fl ow
and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

DIESEL FUEL
Refuelling
A label on the inside of the fuel fi ller
fl ap indicates the type of fuel to be
used.
To fi ll the tank safely:

 it is imperative that you switch
off the engine,

 open the fuel fi ller fl ap,

 insert the key in the fuel tank cap
then turn it to the left. Petrol engines are designed to run
on 95 RON fuel.
However, for better vehicle perform-
ance (petrol engines), we recommend
98 RON.

For petrol engines with catalytic
converter, use of unleaded fuel is
obligatory.
The fi ller neck has a narrower orifi ce
to admit only petrol fi ller nozzles.
UNLEADED PETROL

When you are fi lling your fuel
tank, do not persist after the
third cut-off; this could cause
your vehicle to malfunction.
FUEL TANK

Capacity of the tank: approxi-
mately 60 litres.
Low fuel level
When the minimum level
in the fuel tank is reached,
this warning lamp in the in-
strument panel comes on,
accompanied by an audible signal
and a message on the multifunction
screen.

You have enough fuel left to drive
approximately 30 miles (50 km).
Fuel cut-off switch
Your vehicle is equipped with a safety
device which cuts off the fuel supply
in the event of a collision.

If you have put in fuel that is
wrong for your vehicle, it is es-
sential to have the tank drained
before you start the engine.
A label inside the fuel fi ller fl ap indi-
cates the fuels authorised:

In winter conditions, starting from
cold may seem diffi cult. During
periods of very cold weather we
recommend the use of 95 or 98
unleaded petrol in preference to
B85 so as to ensure optimum
starting performance.
BioFlex
Your vehicle has been designed to
operate
equally on unleaded pet-
rol (95 or 98) or on bioethanol (in
Europe this is a mixture of 85 %
ethanol and 15 % unleaded petrol,
known as E85 ).
Other than the question of the two
authorised fuels, your vehicle is
used in the same way as a traditional
petrol vehicle.

Temporary manual operation
when in automatic mode
By pulling either of the paddles
" + " or " - ", you can exercise tempo-
rary control over gear changing.
The request to change gear will be
taken into account. You will still be
in automatic mode. The warning
lamp A remains lit up in the instru-
ment panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

 Move the selector to position A .
The warning lamp A lights up in
the instrument panel to confi rm
the selection.
The gearbox then functions in auto-
matic mode, without any action on
your part.
It constantly selects the gear that is
best suited to the following condi-
tions:
- driving style,
- road profi le,
- optimum fuel consumption.
Operation in automatic mode
Cancellation of automatic
mode
The change from position A (driv-
ing in automatic mode) to position M
(driving in manual mode) or vice
versa can be made at any time. The
warning lamp A disappears in the in-
strument panel.

BLEEDING THE DIESEL FILTER
Protective cover
Removal

 Remove the protective cover by
unclipping fi rst point 1 , then 3
and 4 .

 Unclip point 2 pulling towards
you, then lift.
Refi tting

 Clip point 2 fi rst.

 Lower the cover, centring it.

 Clip points 1 and 4 , pushing ver-
tically and slightly rearwards.

 Clip point 3 , pushing vertically. Bleeding water from the fuel
filter
Bleed on a regular basis (at every
oil change).
To evacuate the water, slacken the
bleed screw or the water-in-diesel-
fuel sensor, which is located at the
base of the fi lter.
Persist until water ceases to fl ow out.
Then retighten the bleed screw or
the water-in-diesel-fuel sensor.
