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.

Cooling of the engine when stopped
The engine cooling fan may star t after
the engine has been switched off.
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.

For more information on the Warning
and indicator lamps and the associated
alerts, or the Indicators , refer to the
corresponding sections.
Once the AdBlue
® tank is empty, a system
required by regulations prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from your vehicle will no longer
meet the Euro 6

standard: your vehicle
becomes polluting.
In the event of a

confirmed fault with the
SCR system, you must go to a
CITROËN
dealer or a

qualified workshop as soon
as possible: after travelling a
distance
of 685

miles (1,100 km), a system will be
triggered automatically to prevent engine
starting.
In either case, a range indicator gives you
the distance you can travel before the
vehicle is immobilised.
Freezing of the AdBlue
®
AdBlue® freezes at temperatures below
around -11°C.
The SCR system includes a
heater for the
AdBlue
® tank, allowing you to continue
driving in very cold conditions.
Supply of AdBlue®
It is recommended that the AdBlue® be topped
up as soon as the first alert is issued indicating
that the reser ve level has been reached.
In order to ensure that the SCR system
operates correctly:
-

U

se only AdBlue
® fluid that meets the
ISO
22241
standard.
-

N

ever transfer AdBlue
® to another
container: it would lose its purity.
-

N

ever dilute AdBlue
® with water.
You can obtain AdBlue
® from a CITROËN
d
ealer or a

qualified workshop.
You can also visit a

ser vice station equipped
with AdBlue
® pumps specially designed for
passenger vehicles.
Recommendations on
storage
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never keep bottles or containers of
AdBlue
® in your vehicle.
Precautions for use
AdBlue® is a urea-based solution. This liquid
is
non-flammable, colourless and odourless
(when kept in a
cool place).
In the event of contact with the skin, wash the
affected area with soap and water. In the event
of contact with the eyes, wash (irrigate) the
eyes with large amounts of water or with an eye
wash solution for at least 15
minutes. If you feel
a

persistent burning sensation or irritation, get
medical attention.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (at high temperature,
for example), the risk of release of ammonia
cannot be excluded: do not inhale the vapour.
Ammonia has an irritant effect on mucous
membranes (eyes, nose and throat).
AdBlue
® freezes below about -11°C and
deteriorates above 25°C. It should be stored in
a

cool place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a
year.

and 13

litres
using AdBlue
® containers.
Or

hen filling at a ser vice station, to stop
after the third automatic cut-off of the
nozzle.
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.
