Changing the battery
The remote control is supplied by a
6 V-28L battery, which is supplied.
Information on the display indicates
when it is time to replace this battery.
Unclip the casing then replace the
battery.
The remote control must then be
reinitialised, see below.
Always switch off the program-
mable heating while fi lling with
fuel to avoid any risk of fi re or
explosion.
To avoid any risk of poisoning and
asphyxiation, the programmable
heating must not be used, even
for short periods, in an enclosed
space such as a garage or work-
shop which is not equipped with an
exhaust gas extraction system.
Do not park the vehicle on an
infl ammable surface (dry grass,
dead leaves, paper…), there is a
risk of fi re.

The programmable heating system
is supplied by the vehicle's fuel tank.
Before use, ensure that the quantity
of fuel remaining is suffi cient. If the
fuel tank is at the reserve, we strong-
ly advise that you do not programme
the heating.


Do not discard the used
batteries, take them to an
approved collection point.

Reinitialising the remote control
If the vehicle's battery is disconnected
or the remote control's battery is re-
placed, the remote control must be
reinitialised.
After switching on the power, press
button 4
(OFF) for 1 second within
the next 5 seconds. If the operation
has taken place correctly the mes-
sage "OK"
is displayed on the remote
control screen.
If a problem occurs, the message
"FAIL"
appears. Repeat the operation.

In addition, your programmable
heating can be used to pre-heat
your vehicle's passenger com-
partment.
The interior volumetric protection
alarm movement sensor may be
disturbed by the fl ow of air from
the programmable heating when
it is in operation.
To avoid any unexpected trigger-
ing of the alarm during use of the
programmable heating, it is ad-
visable to deactivate the interior
volumetric protection.

FUEL TANK


Capacity of the tank: approxi-
mately
71 litres

*
.



Low fuel level

When the minimum level
in the tank is reached,
this warning lamp comes
on in the instrument
panel, accompanied by an audible
warning and a message on the mul-
tifunction screen. When it fi rst comes
on, there remains around 5 litres of
fuel in the tank.
You must refuel to avoid running out
of fuel.


)
Press at the top left corner, then
pull open from the left.


)
turn the key a quarter turn to lock
and unlock the fi ller cap,

)
when refuelling, place the cap on
hook A
,

)
fi ll the tank, but do not persist
after the third cut-off
; this could
cause your vehicle to malfunction.


While you are refuelling, the engine
must be stopped and the ignition
switched off.


For a petrol engine with a cata-
lytic converter, unleaded fuel is
compulsory.



Opening the fuel flap

Additions of fuel must be of at least
5 litres to be taken into account by
the fuel gauge.
The fi ller neck is narrower to en-
sure that only unleaded petrol noz-
zles can be put in.
Opening the fi ller cap may create
a noise of an inrush of air. This
vacuum, which is entirely normal,
is caused by the sealing of the fuel
system.


Refuelling








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

ACCESS










Quality of the fuel used for
petrol engines

The petrol engines are perfectly
compatible with E10 type petrol
biofuels (containing 10 % ethanol),
conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for
vehicles marketed for the use of this
type of fuel (BioFlex vehicles). The
quality of the ethanol must comply
with European standard EN 15293.
For Brazil only, special vehicles are
marketed to run on fuels containing
up to 100 % ethanol (E100 type).














Quality of the fuel used for
Diesel engines

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
diluted, domestic fuel...) is strictly
prohibited (risk of damage to the en-
gine and fuel system).


















MISFUEL PREVENTION
(DIESEL) *

Mechanical device which prevents
fi lling the tank of a Diesel vehicle
with petrol. It avoids the risk of en-
gine damage that can result from fi ll-
ing 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 intro-
duced 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.

DRIVING








GEAR EFFICIENCY
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 engagement recommen-
dations must not be considered
compulsory. In fact, the confi gu-
ration of the road, the amount of
traffi c and safety remain determin-
ing 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 in-
strument panel screen in the form of
an arrow accompanied by the sug-
gested 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 overtak-
ing...), the system will not recom-
mend a gear change.
The system never suggests:


- engaging fi rst gear,

- engaging reverse gear,

- engaging a lower gear.

DRIVING











STOP & START

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 engine 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



- 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
.
Going into engine STOP mode

The "ECO"
warning lamp comes
on in the instrument panel and
the engine goes into standby:
If your vehicle is fi tted
with the system, 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.

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 func-
tionality of the vehicle, such as for ex-
ample, braking, power steering...

Never refuel with the engine in
STOP mode; you must switch
off the ignition with the key.
Special cases: STOP mode not
available
In this case, the "ECO"

warning lamp fl ashes for a
few seconds then goes off.

This operation is perfectly normal.
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.
