Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►  Monitor your environment and keep your
hands on the wheel to be able to react to anything
that may happen any time.
►  Drive smoothly, anticipate the need for braking
and maintain a longer safety distance, especially
in bad weather.
►  Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►  During long trips, take a break every two
hours.
Important!
Never leave the engine running in a closed
space without sufficient ventilation.
Internal combustion engines emit toxic
exhaust gases such as carbon monoxide.
Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied. Risk of overheating and damage
to the braking system!
Do not park the vehicle or leave the engine
running on a flammable surface (dry
grass, dead leaves, etc.). The exhaust system
of your vehicle is very hot, even several
minutes after the engine stops. Risk of fire!
Never leave a vehicle unattended with the
engine running. If you have to leave your
vehicle with the engine running, apply the
parking brake and put the gearbox into neutral
or position N or P (depending on the type of
gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
►  check that the depth of water does not exceed
15 cm, taking account of waves that might be
generated by other users,
►  deactivate the Stop & Start function,
►  drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
►  do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when driving,
the driver should pay particular attention.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during charging
to cool the on-board charger and the traction
battery.
On the inside
During use, you may hear certain perfectly normal
noises specific to electric vehicles, such as:
–

Traction ba
ttery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
– Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.

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!

Practical information07
The check and top-up must only be done with the
engine cold.
A low level presents a risk of serious damage to
the engine.
The level of this fluid should be close to the "MAX"
mark but should never exceed it.
If the level is close to or below the "MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of this
fluid is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when
necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi), and
in particular on the supply of AdBlue, refer to the
corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according to
your engine.
Otherwise, have them checked by a dealer or a
qualified workshop.
Only use products recommended by the
Manufacturer or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, the Manufacturer selects and
offers very specific products.
12 V battery
The battery does not require any
maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by a
dealer or by a qualified workshop.
Passenger compartment filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city
driving), change it twice as often, if necessary.
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate undesirable
odours.
Air filter
Depending on the environment and the use
of the vehicle (e.g. dusty atmosphere, city
driving), change it twice as often, if necessary.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).

Practical information07
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.

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.
