Recommendations on storage
AdBlue® freezes at about -11°C and deteriorates
above +25°C. Containers should be stored in a
cool area and protected from direct sunlight.
Under these conditions, the fluid can be kept for
at least a year.
If the fluid has frozen, it can be used once it has
completely thawed out at room temperature.
Never store AdBlue® containers in your
vehicle.
Precautions for use
AdBlue® is a urea-based solution. This fluid 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 running water. In the
event of contact with the eyes, immediately rinse
the eyes with large amounts of water or with an
eye wash solution for at least 15 minutes. Seek
medical attention if you feel a persistent burning
sensation or irritation.
If swallowed, immediately wash out the mouth
with clean water and then drink plenty of water.
In certain conditions (high temperature, for
example), the risk of release of ammonia cannot
be excluded: do not inhale the fluid. Ammonia
vapours have an irritant effect on mucous
membranes (eyes, nose and throat).
Store AdBlue® out of the reach of children,
in its original container.
Procedure
Before starting the top-up procedure, ensure that
the vehicle is parked on a flat and level surface.
In wintry conditions, ensure that the temperature
of the vehicle is above -11 °C. Otherwise, the
AdBlue
® may be frozen and therefore cannot be
poured into its tank. Park your vehicle in a warmer
area for a few hours to allow the top-up to be
carried out.
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.
Important: in the event of a top-up after an
AdBlue breakdown, you must wait about
5 minutes before switching on the ignition,
without opening the driver's door, unlocking
the vehicle or bringing the electronic key into
the passenger compartment.
Switch on the ignition, then wait for 10
seconds before starting the engine.
►  Press the "START/STOP" button to switch off
the engine.


►  Turn the blue cap of the AdBlue® tank a 6th of a
turn anti-clockwise and remove it.
►  With a container of AdBlue
®: after checking
the expiry date, read carefully the instructions
on the label before pouring the contents of the
container into the vehicle's AdBlue tank.
►  With an AdBlue
® pump: introduce the nozzle
and fill the tank until the automatic cut-off of the
nozzle.
In order not to overfill the AdBlue® tank:
–
Add betw
een 10 and 13 litres using
AdBlue
® containers.
–
St
op after the nozzle’s first automatic cut-
out, if you are refilling at a service station.
If the AdBlue® tank is completely empty
– which is confirmed by the “Top
up AdBlue: Starting impossible” message – it is
essential to add at least 5 litres.

►  Remove the bulb and change it.
To refit, carry out these operations in reverse
order, directing the bulb’s positioning lug
downwards.

circumstances be discarded with household
waste.
Take used remote control batteries and vehicle
batteries to a special collection point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be carried
out in a well ventilated area and away from
naked flames and sources of sparks, to avoid
any risk of explosion or fire.
Wash your hands afterwards.
Electric motor
Flat accessory battery
It is not possible to start the motor or
recharge the traction battery.
Precautions before working on the
accessory battery
Select mode P, switch off the ignition, check
that the instrument panel is off and that the
vehicle is not plugged in.
Recharging the accessory battery
Do not recharge the battery without first
disconnecting the terminals and removing the
battery from the motor compartment.
Do not disconnect the battery terminals while
the READY lamp is lit, or while the vehicle is
charging.
Access to the battery
The battery is located under the bonnet.

For access to the (+) terminal:
►  Release the bonnet by pulling the internal
release lever, then the external safety catch.
►  Raise the bonnet.
(+) Positive terminal.
This terminal has a quick-release clamp.
(-) Negative terminal.
As the battery's negative terminal is not
accessible, a remote earth point is located facing
the battery.
Vehicles equipped with DS MATRIX LED
VISION headlamps
Never connect jump leads to the metal part on
the back of the headlamps.
Risk of headlamp damage!
Starting using another battery
If your vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the backup battery has
a nominal voltage of 12 V and a capacity at
least equal to that of the discharged battery.
The two vehicles must not be in contact with
each other.

164In the event of a breakdown08
► At the end of the charging operation, switch
off charger B before disconnecting the cables
from battery A.

24v 12v
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components related
to the Stop & Start system.
Never try to charge a frozen battery - risk
of explosion!
If the battery has frozen, have it checked by
a dealer or by a qualified workshop who will
verify that the internal components have not
been damaged and that the case has not
cracked, which would mean a risk of toxic and
corrosive acid leaking.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Disconnecting the battery
In order to maintain an adequate state of charge
for starting the engine, it is recommended that
the battery be disconnected if the vehicle is taken
out of service for a long period. Before disconnecting the battery:
► 
Close all openings (doors, boot, windows,
roof).
►  Switch off all electrical consumers (audio
system, wipers, lighting, etc.).
►  Switch off the ignition and wait for 4 minutes.
At the battery, it is only necessary to disconnect
the (+) terminal.
Quick-release terminal clamp
Disconnecting the (+) terminal

►  Depending on equipment, lift the plastic cover
on the (+) terminal.
►  Raise lever A fully to release clamp B.
►  Remove clamp B by lifting it off.
Reconnecting the (+) terminal

► Raise lever A fully.
►  Refit the open clamp B on the (+) terminal.
►  Push clamp B fully down.
►  Lower lever A to lock clamp B.
►  Depending on equipment, lower the plastic
cover on the (+) terminal.
Do not force the lever as locking will be
impossible if the clamp is not positioned
correctly; start the procedure again.
After reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
If minor problems nevertheless persist following
this operation, contact a dealer or a qualified
workshop.
Referring to the relevant section, reset certain
equipment:
– Electronic key.
– Electric windows.
– Date and time.
– Preset radio stations.
After reconnection of the battery, the
“Collision risk detection system fault”
message is displayed on the instrument panel
when the ignition is switched on. This
operation is perfectly normal. The message
will disappear while driving.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous period of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
