Engine oil level indicator

The vehicle must be on level
ground and the engine must
have been off for more than
30 minutes for this level check to
be accurate.
Oil level correct
This is indicated by the fl ashing of
"OIL"
or the display of a specifi c mes-
sage in the instrument panel, coupled
with the service warning lamp and ac-
companied by an audible signal.
If the low oil level is confi rmed by a
check using the dipstick, the level must
be topped up to avoid damage to the
engine.

the dipstick and the oil fi ller cap on your
engine.
Oil level incorrect This is indicated by the fl ashing of
"OIL --"
or the display of a specifi c mes-
sage in the instrument panel. Contact a
CITROËN or a qualifi ed workshop.
There are 2 marks on the

via the oil fi ller cap, us-
ing the correct grade of
oil for your engine.

This information is displayed for a few
seconds when the ignition is switched

RECOMMENDATIONS FOR VENTILATION AND AIR
CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air
intake grilles located at the base of the windscreen, the nozzles, the vents
and the air outlets, as well as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.

)
Ensure that the passenger compartment fi lter is in good condition and
have the fi lter elements replaced regularly (refer to the "Checks" sec-
tion).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).

)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a set-
ting high enough to quickly
change the air in the passenger
compartment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.



Stop & Start
The heating and air conditioning systems only work when the engine is run-
ning. To maintain a comfortable temperature in the passenger compartment,
you can temporarily deactivate the Stop & Start system (see "Driving").

Lost keys

Visit a CITROËN dealer with the vehicle's registration document, your per-
sonal identifi cation documents and if possible the key code label.
The CITROËN dealer will be able to fi nd the key code and the transponder
code required to order a new key.






Do not throw the remote con-
trol batteries away, they contain
metals which are harmful to the
environment.
Take them to an approved col-
lection point.

Remote control

The high frequency remote control is a sensitive system; do not operate it
while it is in your pocket as there is a possibility that it may unlock the ve-
hicle, without you being aware of it.
Do not repeatedly press the buttons of your remote control out of range and
out of sight of your vehicle. You run the risk of stopping it from working and
the remote control would have to be reinitialised.
The remote control does not operate when the key is in the ignition switch,
even when the ignition is switched off, except for reinitialisation.


Locking the vehicle

Driving with the doors locked may make access to the passenger compart-
ment by the emergency services more diffi cult in an emergency.
As a safety precaution (with children on board), remove the key from the
ignition switch when you leave the vehicle, even for a short time.


Anti-theft protection

Do not make any modifi cations to the electronic engine immobiliser system;
this could cause malfunctions.


When purchasing a second-hand vehicle

Have the pairing of all of the keys in your possession checked by a
CITROËN dealer, to ensure that only your keys can be used to open and
start the vehicle.

FUEL TANK


Capacity of the tank: approximately
60 litres.

When the low fuel level in the
tank is reached, this warning
lamp comes on in the instru-
ment panel, accompanied by
an audible warning and an alert
message. When it fi rst comes
on, around 6 litres
of fuel re-
main in the tank.
Until suffi cient fuel has been added,
every time the ignition is switched on,
this warning lamp appears, accompa-
nied by an audible signal and an alert
message. Depending on version, when
driving, this audible signal and the dis-
play of this alert message are repeated
with increasing frequency, as the level
drops towards 0
.
You must refuel as soon as possible to
avoid running out.
If you run out of fuel (Diesel), refer also
to "Checks".


Low fuel level

Refuelling

Additions of fuel must be of at least
5 litres to be registered by the fuel gauge.
Opening the fi ller cap may result in an
inrush of air. This vacuum is entirely
normal and results from the sealing of
the fuel system.
If you have put in the wrong
fuel for your vehicle, you must
have have the tank drained and
refi lled with the correct fuel be-
fore you start the engine.

)
Press control A
until the automatic
opening of the fuel fl ap is heard.
This control remains active for a few
minutes after switching off the igni-
tion. If necessary, switch the ignition
on again to reactivate it.

If you are fi lling your tank to the top,
do not persist after the third cut-off;
this could cause your vehicle to mal-
function.

)
Take care to select the pump that
delivers the correct fuel for your ve-
hicle.

)
Introduce the nozzle so as to push
in the metal non-return fl ap B.


)
Make sure that the nozzle is pushed
in as far as possible before starting
to refuel (risk of blowback).

)
Maintain this position while refuel-
ling.

)
Push the fuel fl ap to close it.





With Stop & Start, never refuel
with the system in STOP mode;
you must switch off the ignition
with the key.

MISFUEL PREVENTION
(DIESEL) *

Mechanical device which prevents fi ll-
ing the tank of a Diesel vehicle with
petrol. It avoids the risk of engine dam-
age that can result from fi lling with the
wrong fuel.
Located in the fi ller neck, the misfuel
prevention device appears when the
fi ller cap is removed.


Operation

When a petrol fi ller nozzle is introduced
into the fuel fi ller neck of your Diesel
vehicle, it comes into contact with the
fl ap. The system remains closed and
prevents fi lling.

Do not persist but introduce a Diesel
type fi ller nozzle.


It remains possible to use a fuel
can to fi ll the tank; this must be
done slowly.
In order to ensure a good fl ow of
fuel, do not place the nozzle of
the fuel can in direct contact with
the fl ap of the misfuel prevention
device.

This equipment will become available
during the year.

*
According to country of sale.

Travelling abroad
As Diesel fuel pump nozzles
may be different in other coun-
tries, the presence of the misfuel
prevention device may make re-
fuelling impossible.
Before travelling abroad, we
recommend that you check with
the CITROËN dealer network,
whether your vehicle is suitable
for the fuel pumps in the country
in which you want to travel.
