A few definitions…
Range
(miles or km) Current fuel consumption
(mpg or l/100 km or km/l)
Average fuel
consumption
(mpg or l/100 km or km/l) Average speed
(mph or km/h) Distance travelled
(miles or km)
This indicates the distance which
can still be travelled with the fuel re-
maining in the tank in relation to the
average fuel consumption over the
last few miles (kilometres) travelled. This value may vary following a
change in the style of driving or
the relief, resulting in a signifi cant
change in the current fuel con-
sumption.
When the range falls below 20 miles
(30 km), dashes are displayed. After
fi lling with at least 5 litres of fuel,
the range is recalculated and is dis-
played when it exceeds 60 miles
(100 km).
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer. This function is only displayed from
20 mph (30 km/h).
This is the average fuel consump-
tion during the last few seconds.
This is the average fuel consump-
tion since the last trip computer zero
reset.
This is the average speed calculat-
ed since the last trip computer zero
reset (ignition on). This indicates the distance travelled
since the last trip computer zero reset.
Stop & Start time
counter
(minutes/seconds or hours/
minutes)
If your vehicle is fi tted with Stop &
Start, a time counter calculates the
time spent in STOP mode during a
journey.
It resets to zero every time the igni-
tion is switched on with the key.

Warning lamp is on Cause Action/Observations

Low fuel
level fi xed. When it fi rst comes on there
remains
approximately
5 litres of
fuel in the tank. You must refuel as soon as possible to
avoid running out of fuel.
This warning lamp wil come on every time
the ignition is switched on, until a suffi cient
addition of fuel is made.
Fuel tank capacity: 71 litres.
Never continue to drive until you run out
of fuel, this could damage the emission
control and injection systems.

Maximum
coolant
temperature fi xed red.
The temperature of the
cooling system is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down
before topping up the level, if necessary.
If the problem persists, contact a
CITROËN dealer.

Battery
charge fi xed. The battery charging circuit
has a fault (dirty or loose
terminals, slack or cut
alternator belt, ...). The warning lamp should go off when the
engine is started.
If it does not switch off, contact a CITROËN
dealer.

unfastened fi xed.
The driver and/or the front/
rear passenger has not
fastened or has unfastened
their seat belt. Pull the strap then insert the tongue in the
buckle.

Seat belts
not fastened/ unfastened fi xed, associated
with the seat belt not fastened/unfastened
warning lampl. The illuminated dots represent the not
fastened/unfastened passengers.
They come on:
- fi xed for 30 about seconds on starting the
vehicle,
- fi xed from 0 to 12 mph (0 to 20 km/h) when driving,

Capacity of the tank: approximately
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 multifunction
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 ensure
that only unleaded petrol nozzles
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.

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.
Consult a CITROËN dealer.
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).
MISFUEL PREVENTION
Mechanical device which prevents
fi lling the tank of a Diesel vehicle
with petrol. It avoids the risk of
engine damage 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 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 is still possible to use a fuel can
to fi ll the reservoir.
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.

BLEEDING THE DIESEL FUEL FILTER
Protective cover
Removal of the cover Bleeding water from the fuel
filter
Bleed regularly (at each oil change).
To bleed the water, slacken the bleed

sor, located at the base of the fi lter.
Continue until all the water has
fl owed out.
Then retighten the bleed screw or
the water detection sensor.

V6 HDi 240 engines

 Pull the protective cover upwards
to remove it.

HDi 140 engine

 Remove the protective cover
by first unclipping at 3 , then 1
and 4 .

 Unclip at 2 by pulling towards
you, then lift up. Refi tting

 Firstly clip in at 2 .

 Lower and centre the cover.

 Clip in at 3 and 4 , pushing verti-

RUNNING OUT OF FUEL (DIESEL)
HDi 110 engine

 Unclip the protective cover to gain
access to the priming pump. HDi 140 and HDi 160 engines

 Unclip the protective cover to gain
access to the priming pump.
Priming the fuel system
In the event of running out of fuel:

 after fi lling (minimum 5 litres)
and removing the protective cover,
operate the manual priming pump,
until some resistance is felt,

 operate the starter motor while
depressing the accelerator pedal
slightly until the engine starts. HDi engines make use of ad-
vanced technology.
All maintenance and repairs require
special qualifi cations which only a
CITROËN dealer can guarantee.
V6 HDi 240 engine with electric
pump
In the event of running out of fuel:

 after adding fuel, turn the ignition
key to position M , wait for a few
seconds,

 operate the starter motor until
the engine starts.
If the engine fails to start after sev-
eral attempts, contact a CITROËN
dealer.
If the engine fails to start at the fi rst
attempt, wait fi fteen seconds before
trying again.
If the engine fails to start after a
few attempts, operate the priming
pump again and then try to start the
engine.
When the engine is idling, accelerate
slightly to complete the bleeding of
the circuit.
