top-up
-

Obtain a bottle of
AdBlue
®. After first
checking the use-by date, read carefully
the instructions on use on the label
before pouring the contents of the bottle
into your vehicle's AdBlue
® tank.
Important: if your vehicle's
AdBlue
® tank is completely empty -
which is confirmed by the alert messages
and the impossibility of starting the engine,
you must add at least 3.8 litres
(so two 1.89 litre bottles).
-

After emptying the bottle, wipe away any

spillage around the tank filler using a
damp cloth.
If any fluid is split or splashed, wash


immediately with cold water or wipe
with a damp cloth.
If the fluid has crystallised, clean it off using
a sponge and hot water.
Use only AdBlue
® that meets

the ISO 22241 standard.
Please check the use-by date.
Read the instructions on the label.
Ensure that you have a suitable filler pipe,
which may or may not be supplied with the
container.

ait 10 seconds before starting the
engine.
Keep AdBlue
® out of the reach of
children, in its original container.
Never transfer AdBlue
® to another container:
it would loose its purity.
Never dilute the fluid with water.
Never pour the fluid into the Diesel fuel tank.
recommendations on storage
Never store containers or bottles of
AdBlue® in your vehicle.
Freezing of the AdBlue
®
The SCR system includes an AdBlue®
tank heater that ensures operation of
the vehicle in normal conditions.
In exceptional situations, such as when the
vehicle is kept at temperatures below -15°C
(5°F) for a long period, there may be an
emission fault alert related to freezing of the
AdBlue
® additive.
Park the vehicle in an area at a more
moderate temperature for a few hours until
the AdBlue
® becomes a fluid again.
The emissions warning lamp does not go off
immediately, but does so after a few miles
of driving.
Never dispose of AdBlue® fluid bottles
in the household waste.
Place them in a special container provided
this purpose or take them to your dealer.
AdBlue® freezes at about -11°C
(12.2° F) and deteriorates above 25°C
(77°F).
It is recommended that containers and
bottles be stored in a cool area and
protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
Additive that has been frozen can be used
once it has thawed out in ambient air.

Access to the battery
Unscrew the 6 access cover retaining
screws.
Lift off or remove completely the access
cover.
Press lever 1 downwards to spread the
clamp.
Remove the terminal 2 from the negative (-)
post. The batteries contain harmful
substances such as sulphuric acid and
lead. They must be discarded in accordance
with the provisions of the law and must not,
in any circumstances, be discarded with
household waste.
Take used batteries to a special collection
point.
The charging operation must be carried
out in a ventilated area away from
naked flames or any possible sources of
sparks to eliminate the risk of explosion
and

fire.
Do not attempt to charge a frozen battery: it
must first be thawed to eliminate the risks of
explosion. If the battery has frozen, before
charging it have it checked by a specialist
who will check that the internal components
have not been damaged and that the
container is not cracked, which could mean
that there is a risk of a leak of toxic and
corrosive acid.
Proceed with a slow charge charge at low
current for a maximum pf about 24 hours to
avoid damaging the battery. Before disconnecting the battery, you must
wait for 2 minutes after switching off the
ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without first
disconnecting the terminals.
Close the windows and doors before
disconnecting the battery.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight difficulties
are experienced after this, please contact a
CITROËN dealer or a qualified workshop.

For more information, refer to your registration certificate.
In each country, it is imperative that the towed loads authorised by
local legislation are complied with. To find out your vehicle's towing
capacities and its gross train weight, consult a franchised dealer.
The maximum authorised speed is reduced when towing (comply
with the legislation in force in your country).
With load transfer, the braked trailer weight can be increased,
on condition that the equivalent of this load is removed from the
vehicle so that the GTW is not exceeded. Warning: towing with a
lightly loaded towing vehicle may have an adverse effect on its road
holding.
The GTW and towed load values indicated are valid up to a
maximum altitude of 1000 metres; the towed load mentioned must
be reduced by 10 % for each additional 1000 metres.
High ambient temperatures may result in a reduction in the
performance of the vehicle in order to protect the engine; when the
ambient temperature is higher than 37 °C, limit the towed weight.
The kerb weight is equal to the weight without load + driver (75
kg) +
fuel tank filled to 90%. Before towing a trailer, check
that:
-

the nose weight on the

towbar ball does not exceed
the value (S) indicated on
the trailer's weights plate,
-

the maximum trailer weight

is less than the value
indicated on the trailer's
weights plate and the Gross
Vehicle Weight (GVW)
does not exceed the value
indicated on the vehicle's
weights plate.
-

in the case of a self-
supporting trailer

, the Gross
Train Weight must not
exceed the value indicated
on the vehicle's weights
plate.
