Opening the filler cap may result in an inrush of

air. This vacuum is entirely normal and results

from the sealing of the fuel system.

Until sufficient fuel has been added, every time

the ignition is switched on, this warning lamp

appears, accompanied by an audible signal

and an alert message. When driving, this

audible signal and alert message are repeated

with increasing frequency, as the level drops

towards 0.

You must refuel as soon as possible to avoid

running out.

Practical information

Fuel supply cut-off

Your vehicle is equipped with a safety device

which cuts off the fuel supply in the event of a

collision.

If you are filling your tank to the top, do not

persist after the third cut-off; this could

cause your vehicle to malfunction.

The petrol or Diesel engine of your 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, the use of unleaded fuel

is compulsory.

The filler neck is narrower, admitting unleaded

petrol nozzles only.

F

Introduce the nozzle so as to push in the

metal non-return flap.

Make sure that the nozzle is pushed in as

far as possible before starting to refuel (risk

of blowback).

Maintain this position while refuelling.

Push the fuel flap to close it.

If you have put in the wrong fuel for

your vehicle, you must have the tank

drained and refilled with the correct

fuel before you start the engine.

229

Practical information

Misfuel prevention (Diesel)*

Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of

engine damage that can result from filling with the wrong fuel.

Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.

Operation

It remains possible to use a fuel can 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.

Not all Diesel vehicles are fitted with

misfuel protection, so before travelling

abroad, we recommend that you check

with the CITROËN dealer network,

whether your vehicle is suitable for the

fuel pumps in the country in which you

intend to travel.

In order to ensure a good flow of fuel,

do not place the nozzle of the fuel can

in direct contact with the flap of the

misfuel prevention device and pour

slowly.

When a petrol filler nozzle is introduced into the

fuel filler neck of your 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.

quality and specification.

In order to optimise the operation of

units as important as those in the

braking system, CITROËN selects and

offers very specific products.

Checking this system must be done by a

CITROËN dealer or a qualified workshop.

After washing the vehicle, dampness,

or in wintry conditions, ice can form

on the brake discs and pads: braking

efficiency may be reduced. Make light

brake applications to dry and defrost

the brakes.

Electric parking brake

This system does not require any

routine servicing. However, in the

event of a problem, have the system

checked by a CITROËN dealer or a

qualified workshop.

AdBlue^®and SCR system

for BlueHDi Diesel engines

The AdBlue^®is held in a special tank with

Once the AdBlue^®tank is empty,

a capacity of about 17 litres: this provides

a driving range of about 12 500 miles

(20 000 km). An alert is triggered automatically

to warn you when the reserve level is

reached: you can then drive about 1 500 miles

(2 400 km) before the tank is empty.

a system required by regulations

prevents starting of the engine.

If the SCR system is faulty, the level

of emissions from your vehicle will no

longer meet the Euro 6 standard: your

vehicle becomes polluting.

In the event of a confirmed fault

with the SCR system, you must go

to a CITROËN dealer or a qualified

workshop as soon as possible: after

a running distance of 650 miles

(1 100 km), a system will be triggered

automatically to prevent engine

starting.

During each scheduled service of your vehicle

by a CITROËN dealer or a qualified workshop,

the AdBlue^®tank is refilled in order to allow

normal operation of the SCR system.

To assure respect for the environment and

conformity with the new Euro 6 emissions

standard, without adversely affecting the

performance or fuel consumption of Diesel

engines, CITROËN has taken the decision to

equip its vehicles with an effective system that

associates SCR (Selective Catalytic Reduction)

with a particle filter (FAP) for the treatment of

exhaust gases.

In either case, a range indicator gives

you the distance you can travel before

the vehicle is immobilised.

If the estimated mileage of your vehicle

between two services is greater than

12 500 miles (20 000 km), it will be necessary

to top-up the AdBlue^®.

SCR system

Using a fluid called AdBlue^®containing urea, a

catalytic converter turns up to 85% of nitrogen

oxides (NOx) into nitrogen and water, which are

harmless to health and the environment.

Practical information

Topping-up the AdBlue^®

Filling the AdBlue^®tank is an operation

included in every routine service on your

vehicle by a CITROËN dealer or a qualified

workshop.

Precautions in use

AdBlue^®is a urea-based solution. This liquid is

non-flammable, colourless and odourless (kept

in a cool area).

Nevertheless, given the capacity of the tank, it

may be necessary to top-up the fluid between

services, more particularly if an alert (warning

lamps and a message) signals the requirement.

You can go to a CITROËN dealer or a qualified

workshop.

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,

wash (irrigate) the eyes with large amounts of

water or with an eye wash solution for at least

15 minutes. If a burning sensation or irritation

persists, get medical attention.

If swallowed, immediately wash out the mouth

with clean water and then drink plenty of water.

In certain conditions (high exterior temperature,

for example), the risk of release of ammonia

cannot be excluded: do not inhale the fluid.

Ammonia vapour has an irritant effect on

mucous membranes (eyes, nose and throat).

Use only AdBlue^®fluid that meets the

ISO 22241 standard.

If you envisage topping-up yourself, please

read the following warnings carefully.

Never dilute AdBlue^®with water.

Never pour AdBlue^®into the Diesel fuel

tank.

Freezing of the AdBlue^®

AdBlue^®freezes at temperatures below

around -11°C.

The supply in a non-drip container or bottle

simplifies topping up. You can obtain 1.89 litre

(half a US gallon) bottles or 5 or 10 litre

containers from a CITROËN dealer or a

qualified workshop.

The SCR system includes a heater

for the AdBlue^®tank, allowing you

to continue driving in all weather

conditions.

Keep AdBlue^®out of the reach of

children, in its original container or

bottle.

Never transfer AdBlue^®to another

container: it would lose its purity.

Never top up from an AdBlue^®

dispenser reserved for heavy goods

vehicles.

Recommendations on storage

Procedure

AdBlue^®freezes at about -11°C and

deteriorates above 25°C. It is recommended

that bottles be stored in a cool area and

protected from direct sunlight.

Before starting the top-up procedure, ensure

that the vehicle is parked on a flat and level

surface.

Under these conditions, the fluid can be kept

for at least a year.

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

has completely thawed out.

F

Switch off the ignition and remove the

key, or if your vehicle has one, press the

START/STOP button to switch off the

engine.

Never store bottles of AdBlue^®in your

vehicle.

F

Raise the boot floor for access to the

AdBlue^®tank.

Secure the boot floor by attaching its cord

to the hook on the parcel shelf support.

Unclip the black plastic blanking plug using

its tab.

Do not dispose of AdBlue^®bottles or

containers in the household waste.

Place them in a container provided

for this purpose or take them to your

dealer.

F

Insert your fingers into the aperture and

turn the blue cap a 6^thof a turn anti-

clockwise.

F

Carefully lift off the cap, without dropping it.

Practical information

F

After emptying the bottle, wipe away any

spillage around the tank filler using a damp

cloth.

Important: in the event of a top-

up after a breakdown because of

a lack of additive, you must wait

around 5 minutes before switching

on the ignition, without opening the

driver's door, locking the vehicle,

introducing the key into the ignition

switch, or introducing the key of the

"Keyless Entry and Starting" system

into the passenger compartment.

Switch on the ignition, then, after

10 seconds, start the engine.

If any additive is split or splashed, wash

immediately with cold water or wipe

with a damp cloth.

If the additive has crystallised, clean it

off using a sponge and hot water.

F

Obtain a bottle of AdBlue^®. After first

checking the use-by date, read carefully

the instructions on use on the label before

pouring the contents of the bottle into your

vehicle's AdBlue^®tank.

F

Refit the blue cap to the tank and turn it a

6^thof a turn clockwise, to its stop.

Refit the black plastic blanking plug,

clipping it in on the flap

Detach the cord from the parcel shelf

support and lower the boot floor.

Never dispose of AdBlue^®additive

bottles in the household waste. Place

them in a special container provided

this purpose or take them to your

dealer.

Important: if your vehicle's AdBlue^®

tank is completely empty - which

is confirmed by the alert displays

and the impossibility of starting the

engine - you must add at least 3.8 litres

(so two 1.89 litre bottles).
