Practical information07
► Take care to select the pump that delivers the
correct fuel type for the vehicle's engine (see a
reminder label on the inside of the filler flap).
►  Turn the filler cap to the left.
►  Remove the filler cap and hang it on its carrier
(on the filler flap).
►  Introduce the filler nozzle and push it in as
far as possible before starting to refuel (risk of
blowback).
►  Fill the tank.
Do not continue past the third cut-off of the
nozzle, as this may cause malfunctions.
►  Refit the filler cap.
►  Turn it to the right.
►  Push the filler flap to close it.
If you have put in the wrong fuel for the
vehicle, you must have the fuel tank
drained and filled with the correct fuel before
starting the engine.
The vehicle is fitted with a catalytic converter, a
device which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded fuel.
The filler neck is narrower, admitting unleaded
petrol nozzles only.
Misfuel prevention (Diesel)
(Depending on country of sale.)
This mechanical device prevents filling the tank of
a Diesel vehicle with petrol.
Located in the filler neck, the misfuel prevention
device is visible when the filler cap is removed.
Operation

When a petrol filler nozzle is inserted into the
fuel filler neck of a Diesel vehicle, it comes into
contact with the flap. The system remains closed
and prevents filling.
Do not persist but introduce a Diesel type filler
nozzle.
It remains possible to use a fuel jerrycan
to fill the tank.
Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Before travelling abroad, it is advisable to
check with a dealer if the vehicle is suitable
for the distribution equipment of the countries
visited.
Charging system (Electric)
400 V electrical system
The electrical system, which operates at a voltage
of approximately 400 V, is identified by orange
cables, and its components are marked with this
symbol:


An electric vehicle’s power train can
become hot during use and after
switching off the ignition.
Observe the warning messages shown on
labels, particularly inside the flap.
All work on or modifications to the vehicle’s
electrical system (including the traction
battery, connectors, orange cables and
other components visible from the interior or
exterior) is strictly prohibited - risk of severe
burns or potentially fatal electric shock (short-
circuit / electrocution)!
In the event of a problem, always contact a
dealer or a qualified workshop.


This label is intended solely for use by
firefighters responding to an incident
involving the vehicle and for maintenance
technicians.
Never allow water or dust to enter the
connector or charging nozzle - risk of
electrocution or fire!
Never connect / disconnect the charging
nozzle or cable with wet hands - risk of
electrocution!
In the event of an accident or impact
The electrical system or the traction
battery may be seriously damaged in the event
of an accident or impact involving the vehicle
underbody.
Stop as soon as it is safe to do so and switch
off the ignition.
Contact a dealer or a qualified workshop
without delay.
In the event of exposure to a fire
Immediately exit and evacuate all
passengers from the vehicle. Never attempt to
fight the fire yourself - risk of electrocution!

reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is important
to have them regularly checked by a dealer or a
qualified workshop.
Timing and accessory kits
Timing and accessory kits are used from
the time the engine is started until it is
switched off. It is normal for them to wear over
time.
A faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
recommended replacement frequency, stated in
distance travelled or time elapsed, whichever is
reached first.
AdBlue® (BlueHDi)
To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of Diesel engines, the Manufacturer
has taken the decision to equip its vehicles with a
system that associates SCR (Selective Catalytic
Reduction) with a Diesel particle filter (DPF) for
the treatment of exhaust gases.
SCR System
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special tank
holding about 15 litres.
Its capacity allows a driving range of
approximately 5,600 miles (9,000 km), which may
vary considerably depending on your driving style.
An alert system is triggered once the reserve level
is reached: it is then possible to drive for a further
1,500 miles (2,400 km) before the tank is empty
and the vehicle blocked.
For more information on the Warning and
indicator lamps and the associated alerts,
or the Indicators, please refer to the
corresponding sections.
Once the AdBlue® tank is empty, a system
required by legislation prevents starting
of the engine.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard: the vehicle becomes
polluting.
In the event of a confirmed SCR system
malfunction, it is essential to visit a dealer or a
qualified workshop. After 680 miles (1,100 km),
a device is automatically activated to prevent
the engine from starting.
In both cases, a range indicator indicates
the distance that can be travelled before the
vehicle is stopped.
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 reserve level has been reached.
For the correct operation of the SCR
system:
–

U

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

Ne

ver transfer AdBlue
® to another container
as it would lose its purity.
–

Ne

ver dilute AdBlue
® with water.
It is possible to obtain AdBlue
® from a dealer or a
qualified workshop as well as at service stations
equipped with AdBlue
® pumps specially designed
for passenger vehicles.
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.
