Practical information
7Store 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 so cannot be poured
into the tank. Park the vehicle in a warmer area
for a few hours to allow the top-up to be carried
out.
Never pour the 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 anti-
clockwise and remove it.
►

With a container of

AdBlue
®: after checking
the expiry date, read the instructions on the
label carefully before pouring the contents of the
container into the vehicle's AdBlue
® tank.
►
With an
AdBlue® pump: insert the nozzle and
fill the tank until the nozzle automatically cuts
out.
In order not to overfill the AdBlue® tank:
–
Add between 10 and 13 litres using
AdBlue® containers.
–
Stop after the nozzle’ s first automatic cut-
out, if you are refilling at a service station.
The system only registers AdBlue
®
intermediate top-ups of 5

litres or more.
If the AdBlue® tank is completely empty
– which is confirmed by the message
“Top up AdBlue: Starting impossible ” – it is
essential to add at least 10 litres.
Top-up detection may not be instantaneous
after addition. It may take a few minutes of
driving before the top-up detection is effective.
Free-wheeling
In certain situations, it is necessary to put the
vehicle into free-wheeling mode (e.g. towing, on
a rolling road, automatic car wash (Wash mode),

Advice on care and maintenance
General recommendations
Observe the following recommendations to avoid
damaging the vehicle.
Exterior
Never use a high-pressure jet wash in
the engine compartment - risk of
damaging the electrical components!
Do not wash the vehicle in bright sunshine or
extremely cold conditions.
When washing the vehicle in an
automatic roller-brush car wash, be sure
to lock the doors and, depending on version,
move the electronic key away and deactivate
the "hands-free" function (Hands-Free
Tailgate Access).
When using a pressure washer, keep the jet
nozzle at a minimum distance of 30 cm from
the vehicle (particularly when cleaning areas
containing chipped paint, sensors or seals).
Promptly clean up any stains containing
chemicals liable to damage the vehicle's
paintwork (including tree resin, bird
droppings, insect secretions, pollen and tar).
Depending on the environment, clean the
vehicle frequently to remove salty deposits
(in coastal areas), soot (in industrial areas)
and mud/salts (in wet or cold areas). These
substances can be highly corrosive.
Contact a PEUGEOT dealer or a qualified
workshop for advice on removing stubborn
stains requiring special products (such as tar
or insect removers).
Preferably, have paint touch-ups performed
by a PEUGEOT dealer or a qualified
workshop.
Interior
When washing the vehicle, never use a
water hose or high-pressure jet to clean
the interior.
Liquids carried in cups or other open
containers can spill, presenting a risk of
