Practical information07
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing, limescale,
etc.).
Diesel fuel additive (Diesel with
particle filter)
On reaching the minimum level in the
particle filter additive tank, this warning
lamp comes on fixed, accompanied by an audible
signal and a warning message.
Topping up
The topping up of this additive must be carried
out quickly.
Visit a dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the 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 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.
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 with
special technology and specifications.
Its replacement should be carried out only by a
dealer or 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)
The start of clogging of the particle filter is
indicated by the temporary lighting of this
warning lamp, accompanied by an alert message.
As soon as traffic conditions allow, regenerate
the filter by driving at a speed of at least 37 mph
(60 km/h), with an engine speed above 2,500
rpm, for about 15 minutes (until the warning lamp
goes out).
If it is not possible to reach 37 mph (60 km/h),
leave the engine running at idle for about 15
minutes, then drive with an engine speed above
2,500 rpm for 15 minutes.

165
Practical information07
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
The 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 its Diesel engines, the
Manufacturer has taken the decision to equip
its vehicles with a system that combines 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 17 litres.
Its capacity allows a driving range of
approximately 3,900 miles (6,500 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 is immobilised.
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 device
required by law prevents the engine from
being restarted.
If the SCR system is faulty, the level of
emissions from the vehicle will no longer meet
the Euro 6 standard and the vehicle starts
polluting the environment.
In the event of a confirmed SCR system
malfunction, it is essential to visit a dealer or a
qualified workshop. After 660 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.
You can obtain AdBlue
® from a dealer or a
qualified workshop, as well as 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.

182
In the event of a breakdown08
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 electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt, etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►  Connect the red cable to the (+) terminal of
flat battery A (at the metal elbow), then to the (+)
terminal of the backup battery B or of the booster.
►  Connect one end of the green or black cable
to the (-) terminal of the backup battery B or of
the booster (or to an earth point on the assisting
vehicle).
►  Connect the other end of the green or black
cable to the earth point C.
►  Start the engine on the assisting vehicle and
leave it running for a few minutes.
►  Operate the starter on the broken down
vehicle and let the engine run.
If the engine does not start immediately, switch
off the ignition and wait a few moments before
trying again.
►  Wait for it to return to idle.
►  Disconnect the jump leads in reverse order.
►  Refit the plastic cover to the (+) terminal, if
the vehicle has one.
►  Allow the engine to run for at least 30 minutes,
with the vehicle stationary, so that the battery
reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions (e.g.
Stop & Start).
Charging the battery using a battery
charger
For optimum service 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:
–

When using the v
ehicle mainly for short
journeys.
–

If the v
ehicle is to be taken off the road for
several weeks.
Contact a dealer or a qualified workshop.
To charge the vehicle's battery yourself,
use only a charger compatible with
lead-acid batteries with 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.
►  Switch the ignition off.
►  Switch off all electrical consumers (audio
system, lighting, wipers, etc.).


►  Switch off charger B before connecting
the cables to the battery, so as to avoid any
dangerous sparks.
►  Ensure that the charger cables are in good
condition.
