Fuel tank
Capacity of the tank: Approximately
53
litres.
Low fuel level
When the level in the tank becomes
low, this warning lamp comes on in
the instrument panel, accompanied
by the display of a
message and an
audible signal. When it first comes
on, there remains about 6


litres of
fuel in the tank.
Refuelling
Fuel top-ups must be of at least 5 litres in order
t o be registered by the fuel gauge.
Opening the filler cap may create a
noise
caused by an inrush of air. This vacuum is To refuel in complete safety:

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 filler neck is narrower, admitting unleaded
petrol nozzles only.
If your vehicle is fitted with Stop & Start,
never refuel with the engine in STOP
mode; you must switch off the ignition.
Misfuel prevention (Diesel)
(Depending on country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol.
Operation
Until sufficient fuel is added, this warning lamp
reappears every time the ignition is switched
on, accompanied by the message and the
audible signal. When driving, this message
and audible signal are repeated with increasing
frequency as the fuel level drops towards 0 .
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel) , refer to the corresponding section. entirely normal and results from the sealing of
the fuel system.
Practical information

181
It remains possible to use a fuel can to fill
t he tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with a
CITROËN dealer whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.
When a
petrol filler nozzle is introduced into
the fuel filler neck of a Diesel vehicle, it comes
into contact with the flap. The system remains
closed and prevents filling.
Do not persist but introduce a Diesel type
filler nozzle.
Compatibility of fuels
The use of any other type of (bio) fuel
(vegetable or animal oils, pure or diluted,
domestic fuel, etc.) is strictly prohibited
(risk of damage to the engine and fuel
syste m). The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol
respectively.
Diesel fuels conforming to the EN590,
EN16734 and EN16709 standards respectively
and containing up to 7%, 10%, 20% and 30%
fatty acid methyl ester respectively. The use of
B20
or B30 fuels, even occasionally, imposes
special maintenance conditions referred to as
"Arduous conditions".
Paraffinic Diesel fuel conforming to the
EN15940

standard.
Diesel at low temperature
At temperatures below 0°C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating
correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50% full.
At temperatures below -15°C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Cer tain fuels could damage your vehicle's
engine.
In cer tain countries, the use of a
par ticular
fuel may be required (specific octane
rating, specific trade name, etc.) to ensure
correct operation of the engine.
For all additional information, consult a


dealer.

Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a
level drops significantly, have the
corresponding system checked by a
CITROËN
dealer or a
qualified workshop.
The fluids must comply with the
manufacturer's requirements and with the
vehicle's engine.

Practical information

191
During the 30 minutes after topping up the
o il, the check per formed with the oil level
indicator in the instrument panel when the
ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close
to the " MAX" mark. If not, check the
brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Engine coolant
Check the engine coolant level
regularly.
It is normal to top up this fluid
between two services. The check and top-up must only be done with
the engine cold.
A low level presents a
risk of serious damage
to the engine.
The level of this fluid should be close to the
" MAX " mark but should never exceed it.
If the level is close to or below the " MIN" mark,
it is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying out any
work.
To avoid the risk of scalding if you need to top
up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow
the pressure to drop.
Once the pressure has dropped, remove the
cap and top up to the required level.
If topping up, clean the cap before
replacing it. Use only DOT4 brake fluid
from a sealed canister.

Take care with objects or clothing that
could be caught in the blades of the
fan!Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The screenwash fluid must be topped up with
a ready for use mix.
In winter (temperatures below zero), a liquid
containing an anti-freeze agent must be
used which is appropriate for the prevailing
conditions, in order to preser ve the elements of
the system (pump, tank, ducts, etc.).
Filling with pure water is prohibited
under all circumstances (risk of freezing,
limestone deposits, jets, etc.).
Diesel fuel additive (Diesel
with particle filter)
or The minimum level in the particle
filter additive tank is indicated by fixed
illumination of this warning lamp,
accompanied by an audible warning
and a
message warning that the level
of additive is too low.
To p p i n g u p
This additive must be topped up without delay
by a CITROËN dealer or a qualified workshop.

Important: in the event of a
top-up after
a

breakdown because of a lack of
AdBlue, you must wait around 5
minutes
before switching on the ignition, without
opening the driver's door, unlocking
the vehicle, introducing the key into
the ignition switch, or introducing
the key of the Keyless Entr y and
Star ting system into the passenger
compartment .
Switch on the ignition, then wait for
10


seconds before starting the engine.
Keep AdBlue
® out of the reach of children,
in its original container or bottle.
Procedure
Before starting the top-up procedure, ensure
that the vehicle is parked on a flat and level
sur face.
Do not pour AdBlue
® if the temperature of the
vehicle is less than -11°C. Park your vehicle in
a

warmer area for a

few hours to allow the top-
up to be carried out.
In the event of an AdBlue
® breakdown,
confirmed by the message "Add AdBlue:
Starting impossible", you must top up with
at least 5

litres.
Never pour AdBlue
® into the Diesel fuel
tank.
If any AdBlue
® is splashed, or if there
are any spillages on the bodywork, rinse
immediately with cold water or wipe with
a

damp cloth.
If the fluid has crystallised, clean it off
using a

sponge and hot water.
