Bottles or containers are available from the
dealer network or a qualified workshop.
Never top up from an AdBlue
® dispenser
reserved for heavy goods vehicles.
Recommendations on storage
AdBlue® freezes below around -11°C and
deteriorates above 25°C. It is recommended
that bottles or containers be stored in a
cool
place 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 ambient
temperature.
Never store bottles or containers of
AdBlue
® in your vehicle.
Do not dispose of AdBlue
® bottles or
containers in the household waste.
Place them in a

container provided for
this purpose or take them to your dealer.
Procedure
Before topping up, ensure that the vehicle is
parked on a flat and level sur face.
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 its tank. Park your
vehicle in a

warmer area for a few hours to
allow the top up to be carried out.

F After emptying the bottle or container, wipe away any spillage around the tank filler
using a
damp cloth.
If any AdBlue

for around 5 minutes before switching
on the ignition, without opening the
driver's door , or unlocking the vehicle ,
or placing the key in the ignition
switch .
Switch on the ignition, then after
10


seconds, start the engine.
Advice on care and
maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Textured paint
Textured paint reacts to light with variations of
appearance and finish that emphasise the car's
lines and form. This paint coating has particles
that remain visible and create a unique satin
relief effect. Its lightly granulated texture gives
it a
surprising feel. Observe the following recommendations
to avoid damaging the paint finish:
-

c
hoose a high pressure wash, or at
least a high water delivery; roller brush
washing is compatible.
-
g
ently wipe the body with a clean
microfibre cloth.
-
c
arefully wipe off any fuel spilt on the
body using a soft cloth, then allow to
d r y.
-

c
lean off minor marks (for example,
finger marks), using the product in the
"TECHNATURE" range intended for
removing insects.
H o w eve r,
-

d
o not select the programme with hot
wax finish.
-

d
o not use waterless cleaning.
-

n
ever polish the vehicle.
-

d
o not use paint restorers, abrasive
or polishing products, or bright paint
preser vers (wax polish, for example).
It is always preferable to have paint
repairs carried out in the dealer network or
by a


qualified workshop.

Running out of fuel
(Diesel)
On vehicles fitted with Diesel engines, the fuel
system must be primed if you run out of fuel.For more information on Misfuel
prevention (Diesel) , refer to the
corresponding section.
If the engine does not start first time, do
not keep trying, but start the procedure
again from the beginning.

Temporary puncture
repair kit
Scan the QR code on page 3 to view
e xplanatory videos.
Comprising a
compressor and a sealant
cartridge, it allows the temporary repair of
a

tyre so that you can drive to the nearest
garage.
It is designed to repair most punctures which
could affect the tyre, located on the tyre tread
or shoulder.
The vehicle's electrical system allows the
connection of the compressor for long
enough to inflate a
tyre after a puncture
repair.
Under-inflation detection
After repair of the tyre, the warning
lamp will remain on until the system is
reinitialised.
For more information on Under-inflation
detection , refer to the corresponding
section.

12 V battery
Procedure for starting the engine using another
battery or charging a
discharged battery.
General points
Lead-acid starter batteries
Batteries contain harmful substances
such as sulphuric acid and lead.
They must be disposed of in accordance
with regulations and must not, in any
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, so as to avoid the risk of explosion
or fire.
Wash your hands afterwards.

Access to the battery
The battery is located under the bonnet.
To access it:
F
o
pen the bonnet using the interior release
lever, then the exterior safety catch,
F

s
ecure the bonnet stay,
F

l
ift the plastic cover on the (+) terminal.The battery (-) terminal is not accessible.
A remote earth point is located on the
front left-hand wheel arch.
Starting using another battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a
battery booster. Never try to start the engine by connecting
a
battery charger.
Never use a 24 V or higher battery
b o o s t e r.
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.
Switch off all the electrical consumers
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are not
close to moving parts of the engine (fan,
belts, etc.).
Do not disconnect the (+) terminal while
the engine is running. F

Charging the battery using
a

battery charger
For optimum ser vice life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances it may be necessary to
charge the battery:
-

i
f you use your vehicle mostly for short
journeys,
-

i
f the vehicle is to be taken off the road for
several weeks.
Contact the dealer network or a
qualified
workshop.
If you plan to charge your vehicle's battery
yourself, use only a
charger compatible
with lead-acid batteries of a
nominal
voltage of 12
V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities. It is not necessary to disconnect the
battery.
Never try to charge a frozen battery – Risk
of explosion!
If the battery has frozen, have it checked
in the dealer network or by a
qualified
workshop who will check that the internal
components have not been damaged and
that the container has not cracked, which
would mean a
risk of toxic and corrosive
acid leaking.
Disconnecting the battery
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
F

S
witch off the ignition.
F

S
witch off all electrical consumers (audio
system, lighting, wipers,etc.).
F

S
witch off the charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
F

E
nsure that the charger cables are in good
condition.
F

C
onnect the charger B cables as follows:
-

t
he positive (+) red cable to the (+)
terminal of the battery A ,
-

t
he negative (-) black cable to the earth
point C on the vehicle.
F

A
t the end of the charging operation, switch
off the charger B before disconnecting the
cables from the battery A . If this label is present, it is essential to
use only a
12 V charger to avoid causing
irreversible damage to the electrical
components related to the Stop & Start
system.
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 ser vice for a
long
period.
Before disconnecting the battery:
F

c
lose all openings (doors, boot, windows,
roof (for Cabrio versions)),
