Practical information

The check and top-up must only be done with the

engine cold.

Filling with pure water is prohibited under

all circumstances (risk of freezing,

limestone deposits, etc.).

12 V battery

The battery does not require any

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.

maintenance.

However, check regularly that the terminals

are correctly tightened (versions without quick

release terminals) and that the connections are

clean.

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.

For more information on the precautions

to take before any work on the 12 V

battery, refer to the corresponding section.

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.

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.

Once the pressure has dropped, remove the cap

and top up to the required level.

Checks

Unless otherwise indicated, check these

components in accordance with the

manufacturer's service schedule and according to

your engine.

can adversely affect air conditioning

system performance and generate undesirable

odours.

Otherwise, have them checked by a dealer or a

qualified workshop.

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.).

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.

oil is changed.

Particle filter (Diesel)

Electric parking brake

Wheels and tyres

The inflation pressure of all tyres,

including the spare wheel, must be

checked on "cold” tyres.

When the particle filter is approaching

saturation, this warning lamp comes on

temporarily, accompanied by a message warning

of the risk of filter clogging.

This system does not require any routine

servicing. However, in case of an issue, do

not hesitate to have the system checked by a

dealer or a qualified workshop.

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.

The pressures indicated on the tyre pressure label

are valid for "cold" tyres. If you have driven for

more than 10 minutes or more than 6 miles (10

kilometres) at over 31 mph (50 km/h), add 0.3 bar

(30 kPa) to the values indicated on the label.

For more information on the Electric

parking brake, refer to the corresponding

section.

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.

Brake pads

Under-inflation increases fuel

consumption. Non-compliant tyre

pressure causes premature wear on tyres and

has an adverse effect on the vehicle's road

holding - risk of an accident!

Brake wear depends on the style of driving,

particularly in the case of vehicles used in

town, over short distances. It may be necessary to

have the condition of the brakes checked, even

between vehicle services.

Driving with worn or damaged tyres reduces the

braking and road holding performance of the

vehicle. It is recommended to regularly check the

condition of the tyres (tread and sidewalls) and

wheel rims as well as the presence of the valves.

When the wear indicators no longer appear set

back from the tread, the depth of the grooves is

less than 1.6 mm; it is imperative to replace the

tyres.

Unless there is a leak in the circuit, a drop in the

brake fluid level indicates that the brake pads are

worn.

New vehicle

During the first few particle filter

regeneration operations, you may notice a

"burning" smell. This is perfectly normal.

After washing the vehicle, moisture, or in

wintry conditions, ice can form on the

brake discs and pads: braking efficiency may

be reduced. Gently dab the brakes to dry and

defrost them.

qualified workshop. After 680 miles (1,100 km),

a device is automatically activated to prevent

the engine from starting.

Fitting different tyres on the front and rear axles

can cause the ESC to mistime.

SCR System

In both cases, a range indicator indicates

the distance that can be travelled before the

vehicle is stopped.

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.

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.

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.

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.

Timing and accessory kits

Supply of AdBlue^®

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.

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 more information on the Warning and

indicator lamps and the associated alerts,

or the Indicators, please refer to the

corresponding sections.

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.

For the correct operation of the SCR

system:

– Use only AdBlue^®fluid that meets the ISO

22241 standard.

– Never transfer AdBlue^®to another container

as it would lose its purity.

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.

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

– Never 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.

In the event of a confirmed SCR system

malfunction, it is essential to visit a dealer or a

Practical information

Recommendations on storage

Procedure

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.

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.

If the fluid has frozen, it can be used once it has

completely thawed out at room temperature.

►ꢀ Turn the blue cap of the AdBlue^®tank a 6^thof a

turn anti-clockwise and remove it.

Never store AdBlue^®containers in your

vehicle.

Never pour AdBlue^®into the Diesel fuel

tank.

►ꢀ 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.

Precautions for use

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.

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).

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.

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.

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.

Switch on the ignition, then wait for 10

seconds before starting the engine.

►ꢀ Press the "START/STOP" button to switch off

the engine.
