ACCESS
FUEL TANK

Capacity of the tank: approxi-
mately 60 litres.



Low fuel level

When the low fuel level is
reached, this warning lamp
on the instrument panel
comes on, accompanied by
an audible warning and a message
on the multifunction screen.
When it fi rst comes on, about 7 litres

of fuel remain in the tank.
Until suffi cient fuel has been
added, this warning lamp appears
every time the ignition is switched
on, accompanied by an audible
warning and a message. Depending
on version, this audible warning
and message are repeated with
increasing frequency as the fuel
level drops towards " 0
".
Refuel as soon as possible to avoid
running out. A label on the inside of the fuel fi ller
fl ap reminds you of the type of fuel
to use, depending on your engine
type.
Additions of fuel must be of at least
5 litres to be registered by the fuel
gauge.

Refuelling


If you are fi lling your tank to
the top, do not persist after the
3rd cut-off; this could cause
malfunctions.






With Stop & Start, never refuel with
the system in STOP mode; you
must switch off the ignition with the
key. Opening the fi ller cap may result in
an inrush of air. This is entirely nor-
mal and results from the sealing of
the fuel system.


)
Press control switch A
, situated
on the switch panel on the left of
the dashboard, until the fuel fl ap
opens.
This control switch remains ac-
tive for a few minutes after
switching of the ignition. If nec-
essary, switch the ignition on
again to reactivate it.

)
Take care to select the pump
that delivers the correct type of
fuel for your vehicle.

)
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 throughout
the refuelling operation.

)
Push the fuel fl ap to close it.

ACCESS
The petrol or Diesel engine of your ve-
hicle is fi tted with a catalytic converter, a
device which helps to reduce the level of
harmful emissions in the exhaust gases.

For petrol engines, you must use
unleaded fuel.
The fi ller neck is narrower, allowing only
unleaded petrol nozzles to be intro-
duced.

If you have put in the wrong fuel
for your vehicle, you must have
the fuel tank drained and fi lled
with the correct fuel before start-
ing the engine.













Quality of the fuel used for
petrol engines











Quality of the fuel used for
Diesel engines

Fuel cut-off

Your vehicle is equipped with a safe-
ty device which cuts off the fuel sup-
ply in the event of a collision.
The petrol engines are perfectly
compatible with E10 or E24 type pet-
rol biofuels (containing 10 % or 24 %
ethanol), conforming to European
standards EN 228 and EN 15376.
E85 type fuels (containing up to
85 % ethanol) are reserved exclu-
sively for vehicles marketed for the
use of this type of fuel (BioFlex ve-
hicles). The quality of the ethanol
must comply with European stan-
dard EN 15293.
For Brazil only, special vehicles are
marketed to run on fuels containing
up to 100 % ethanol (E100 type).

The Diesel engines are perfectly
compatible with biofuels which con-
form to current and future European
standards (Diesel fuel which com-
plies with standard EN 590 mixed
with a biofuel which complies with
standard EN 14214) available at the
pumps (containing up to 7 % Fatty
Acid Methyl Ester).
The B30 biofuel can be used in cer-
tain Diesel engines; however, this
use is subject to strict application
of the special servicing conditions.
Contact a CITROËN dealer or a
qualifi ed workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or di-
luted, domestic fuel...) is strictly pro-
hibited (risk of damage to the engine
and fuel system).

DRIVING
GEAR SHIFT INDICATOR *

System which reduces fuel con-
sumption by advising the driver to
change up on vehicles fi tted with a
manual gearbox.

Operation

The system intervenes only when
driving economically.
Depending on the driving situation
and your vehicle's equipment, the
system may advise you to skip one
or more gears. You can follow this
instruction without engaging the in-
termediate gears.
The gear recommended should not
be considered compulsory. In fact,
the confi guration of the road, the
amount of traffi c and safety remain
determining factors when choosing
the best gear. Therefore, the driver
remains responsible for deciding
whether or not to follow the advice
given by the system.
This function cannot be deactivated.

* According to engine.
Example:


- You are in third gear.

- You press the accelerator pedal
moderately.

- The system may suggest that
you engage a higher gear, if ap-
propriate.
The information appears in the form
of an arrow in the instrument panel
screen.
Depending on your vehicle's equip-
ment, this arrow may be accompa-
nied by the recommended gear.

In the case of driving which
makes particular demands
on the performance of the
engine (fi rm pressure on
the accelerator pedal, for example,
when overtaking...), the system will
not recommend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

DRIVING
The Stop & Start system puts the en-
gine temporarily into standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine restarts automatically - START
mode - as soon as you want to move
off. The restart takes place instantly,
quickly and silently.
Perfect for urban use, the Stop &
Start system reduces fuel consump-
tion and exhaust emissions as well
as the noise level when stationary.

Operation


Going into engine STOP mode

The "ECO"
warning lamp comes
on in the instrument panel and
the engine goes into standby:


- with the electronic gearbox
system
, at speeds below 4 mph
(6 km/h), press the brake pedal or
put the gear lever in position N
. If your vehicle is fi tted with the sys-
tem, a time counter calculates the
sum of the periods in STOP mode
during a journey. It rests itself to zero
every time the ignition is switched on
with the key.
Special cases: STOP mode not
available

Never refuel with the en-
gine in STOP mode; you
must switch off the ignition
with the key.
For your comfort, during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
for example, braking, power steer-
ing... STOP mode is not invoked
when:


- the driver's door is open,

- the driver's seat belt is not fas-
tened,

- the vehicle has not exceeded
6 mph (10 km/h) since the last
engine start using the key,

- the electric parking brake is ap-
plied or being applied,

- the engine is needed to maintain
a comfortable temperature in the
passenger compartment,

- demisting is active,

- some special conditions (battery
charge, engine temperature,
braking assistance, ambient
temperature...) where the engine
is needed to assure control of a
system.
In this case, the "ECO"
warning
lamp fl ashes for a few seconds then
goes off.

This operation is perfectly normal.
