Practical information

Topping up the engine oil level

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.

Filling with pure water is prohibited under

all circumstances (risk of freezing,

limestone deposits, etc.).

For the location of the engine oil filler cap, please

refer to the corresponding under-bonnet engine

compartment illustration.

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.

►ꢀ Add oil in small quantities, avoiding any spills

on engine components (risk of fire).

►ꢀ Wait a few minutes before checking the level

again using the dipstick.

Diesel fuel additive (Diesel with

particle filter)

On reaching the minimum level

►ꢀ After checking the level, carefully screw the

oil filler cap back on and replace the dipstick in

its tube.

this warning lamp comes on fixed, accompanied

by an audible warning and a message warning

that the additive level is too low.

Within 30 minutes of adding oil, the oil

level indication in the instrument panel

when the ignition is switched on is not valid.

Topping up

This additive must be topped up without delay by

a dealer or a qualified workshop.

Once the pressure has dropped, remove the cap

and top up to the required level.

AdBlue (BlueHDi)

Brake fluid

An alert is triggered when the reserve level is

reached.

The level of this fluid should be close to the

"MAX" mark. If not, check the brake pad

wear.

Screenwash fluid

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.

Top up to the required level when

necessary.

To know how often the brake fluid should be

replaced, refer to the manufacturer's servicing

schedule.

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.).

Clean the cap before removing it to refill.

Use only DOT4 brake fluid from a sealed

container.

Engine coolant

It is normal to top up this fluid between

two services.

171

Practical information

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.

As soon as the traffic conditions permit,

Checks

regenerate the filter by driving at a speed of at

least 37 mph (60 km/h) until the warning lamp

goes off.

Unless otherwise indicated, check these

components in accordance with the

manufacturer's service schedule and according to

your engine.

If the warning lamp stays on, this

indicates a low Diesel additive level.

For more information on Checking levels, refer

to the corresponding section.

Otherwise, have them checked by a dealer or a

qualified workshop.

Air filter

Depending on the environment and the use

of the vehicle (e.g. dusty atmosphere, city

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.

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.

driving), change it twice as often, if necessary.

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.

12 V battery

New vehicle

During the first few particle filter

regeneration operations, you may notice a

"burning" smell. This is perfectly normal.

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.

Oil filter

Manual gearbox

Change the oil filter each time the engine

oil is changed.

The gearbox does not require any

maintenance (no oil change).

For more information on the precautions

to take before any work on the 12 V

battery, refer to the corresponding section.

Practical information

Brake pads

Wheels and tyres

Shock absorbers

Brake wear depends on the style of driving,

The inflation pressure of all tyres,

including the spare wheel, must be

checked on "cold” tyres.

It is not easy for drivers to detect when

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.

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

brake fluid level indicates that the brake pads are

worn.

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.

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.

Timing and accessory kits

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.

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!

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.

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.

Using different size wheels and tyres from those

specified can affect the lifetime of tyres, wheel

rotation, ground clearance, the speedometer

reading and have an adverse effect on road

holding.

Brake disc wear

For information on checking brake disc

wear, contact a dealer or a qualified

workshop.

AdBlue^®(BlueHDi)

To respect the environment and ensure

Electric parking brake

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.

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.

For more information on the Electric

parking brake, refer to the corresponding

section.

Fitting different tyres on the front and rear axles

can cause the ESC to mistime.

173

Practical information

In either case, a range indicator gives the

distance that can be travelled before the

vehicle is immobilised.

Recommendations on storage

SCR system

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.

Using a liquid called AdBlue^®that contains urea,

a catalytic converter turns up to 85% of 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.

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.

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

completely thawed out at room temperature.

Its capacity allows a driving range of

approximately 5,600 miles (9,000 km), highly

dependent on your driving style.

Never store AdBlue^®containers in your

vehicle.

An alert system is triggered automatically once

the reserve level is reached: you can then drive for

a further 1,500 miles (2,400 km) before the tank is

empty and the vehicle disabled.

Supply of AdBlue^®

Precautions for use

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.

AdBlue^®is a urea-based solution. This fluid is non-

flammable, colourless and odourless (when kept

in a cool place).

For more information on the Warning and

indicator lamps and the associated alerts,

or the Indicators, refer to the corresponding

sections.

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).

For the correct operation of the SCR

system:

– Use only AdBlue^®fluid that meets the ISO

22241 standard.

Once the AdBlue^®tank is empty, a system

required by regulations 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 fault with the SCR

system, you must go to a dealer or a qualified

workshop as soon as possible: after travelling

a distance of 685 miles (1,100 km), a system

will be triggered automatically to prevent

engine starting.

– Never transfer AdBlue^®to another container

as it would lose its purity.

– Never dilute AdBlue^®with water.

It is possible to obtain AdBlue^®from a dealer or a

qualified workshop.

You can also visit a service station

equipped with AdBlue^®pumps specially

designed for passenger vehicles.

Store AdBlue^®out of the reach of children,

in its original container.

174

Practical information

Procedure

Do not dispose of AdBlue^®containers in

the household waste.

Place them in a container reserved for this

purpose or take them back to where you

bought them.

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.

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

turn anti-clockwise and remove it.

Free-wheeling

In certain situations, you must allow the vehicle to

free-wheel (while being towed, on a rolling road,

in an automatic car wash, or being transported by

rail or sea freight, etc.).

►ꢀ With a container of AdBlue^®: after checking

the expiry date, read the instructions on the

label carefully 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 nozzle automatically

cuts out.

Never pour AdBlue^®into the Diesel fuel

tank.

The procedure varies according to the type of

gearbox and parking brake.

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.

With manual or EAT6

automatic gearbox and electric

parking brake

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.

The system only registers AdBlue^®top-ups of

5 litres or more.

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.

Release procedure

►ꢀ With the engine running and while depressing

the brake pedal, move the gear selector to the

neutral position.

►ꢀ While depressing the brake pedal, switch off

the ignition.

►ꢀ Release the brake pedal, then switch on the

ignition again.

►ꢀ While depressing the brake pedal, press the

control lever to release the parking brake.

If the AdBlue^®tank is completely empty

– which is confirmed by the message "Top

up AdBlue: Starting impossible" – 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.
