Practical information

For more information on the Warning

and indicator lamps and the associated

alerts, refer to the corresponding section.

The AdBlue^®is contained in a

special tank holding about

17 litres.

AdBlue^®(BlueHDi

engines)

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.

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 estimated distance travelled by your

vehicle between two services is greater than

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

to top up the AdBlue.

To respect the environment and ensure

compliance with the Euro 6 standard, without

adversely affecting the performance or fuel

consumption of its Diesel engines, CITROËN

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.

Supply of AdBlue^®

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 your vehicle will no longer

meet the Euro 6 standard: your vehicle

becomes polluting.

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.

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 travelling the distance of

685 miles (1,100 km), a system preventing

the engine starting will be triggered

automatically.

In either case, a range indicator gives you

the distance you can travel before the

vehicle is immobilised.

In order to ensure that the SCR system

operates correctly:

SCR system

Use only AdBlue^®liquid that meets the

ISO 22241 standard.

Never transfer AdBlue^®to another

container: it would lose its purity.

Never dilute AdBlue^®with water.

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.

149

Practical information

You can obtain AdBlue^®from a CITROËN

dealer or a qualified workshop.

In winter, check that the temperature of the

vehicle is above -11°C. If not, in freezing

Precautions in use

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

non-flammable, colourless and odourless (kept

in a cool area).

weather, the AdBlue^®

cannot be poured into the

tank. Park your vehicle somewhere warmer for

a few hours before topping up.

You can also visit a service station

equipped with AdBlue^®pumps specially

designed for private vehicles (for those

versions with access to the AdBlue^®tank

via the fuel filler flap).

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. If a burning sensation or irritation

persists, get medical attention.

If swallowed, immediately rinse the mouth with

clean water and then drink plenty of water.

In certain conditions (high temperature, for

example), the risk of releasing ammonia cannot

be discounted: do not inhale the fluid. Ammonia

vapour has an irritant effect on mucous

membranes (eyes, nose and throat).

In the event of an AdBlue^®breakdown,

confirmed by the message "Add AdBlue:

Starting impossible", you must top up with

at least 5 litres.

Never top up from an AdBlue^®dispenser

reserved for heavy goods vehicles.

Never pour AdBlue^®into the Diesel fuel

tank.

Recommendations on

storage

AdBlue^®freezes at about -11°C and

deteriorates above 25°C. It should be stored in

a cool place and protected from direct sunlight.

Under these conditions, the fluid can be kept

for at least a year.

For the specifics associated with the

access configuration for the AdBlue^®tank

(via the boot or via the fuel filler flap), refer

to the descriptions given in detail further

on.

Keep AdBlue^®out of reach of children, in

its original container or bottle.

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

has completely thawed out.

If any AdBlue^®is splashed, or if there are

any spillages on the side of the body, 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.

Never keep containers or bottles of

AdBlue^®in your vehicle.

Procedure

Before starting the top up procedure, ensure

that the vehicle is parked on a flat and level

surface.

150

Practical information

F Switch off the ignition and remove the key.

F Take non-drip bottles 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.

Important: in the event of a top-up after

a breakdown because of a lack of

AdBlue, 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.

F With Keyless Entry and Starting, press the

"START/STOP" button to switch off the

engine.

F After filling, perform the same operations in

reverse order.

Switch on the ignition, then wait for 10

seconds before starting the engine.

Access to the AdBlue^®tank

via the fuel filler flap

Access to the AdBlue^®tank

via the boot

Filling the AdBlue^®tank is an operation

included in every routine service on your

vehicle by a CITROËN dealer or a qualified

workshop.

A blue cap under the fuel filler flap indicates

access to the AdBlue^®tank.

Nevertheless, given the capacity of the tank, it

may be necessary to top up the fluid between

services, as soon as an alert (warning lamps

and a message) indicates it.

You are recommended to go to a CITROËN

dealer or a qualified workshop.

F From the boot, lift the carpet and then,

depending on the equipment, lift out the

spare wheel and/or the storage box.

F Without pressing, turn the black cap a

quarter turn anti-clockwise and lift it off.

F Turn the blue cap anti-clockwise.

Read the following procedure carefully to

be able to top up properly.

F Switch off the ignition and remove the key.

If you intend to do the topping-up yourself,

read the following procedure carefully.

F With Keyless Entry and Starting, press the

"START/STOP" button to switch off the

engine.

The supply in a non-drip bottle simplifies the

topping-up.

151

Practical information

F With the vehicle unlocked and the fuel filler

flap open, turn the AdBlue^®blue filler cap

anti-clockwise.

F Obtain a container of AdBlue^®. After first

checking the use-by date, read carefully

the instructions on use on the label before

pouring the contents of the container into

your vehicle's AdBlue^®tank.

Advice on care and

maintenance

For the care of the stickers in the rear door

windows, we recommend the following:

Use a wide jet at a temperature of

between 25°C and 40°C.

Recommendations on the care and

maintenance of your vehicle are given in the

Maintenance and Warranty Guide.

Where possible, direct the jet at right

angles to the stickers.

Leather

Leather is a natural product. Appropriate

regular care and cleaning is essential for its

durability.

F Insert the AdBlue^®pump nozzle and fill the

tank until the nozzle stops automatically.

Refer to your vehicle's Maintenance and

Warranty Guide for information on all the

special precautions to observe.

Important:

To prevent the AdBlue^®tank from

overflowing, it is recommended:

F To top up between 10 and 13 litres

using AdBlue^®containers.

F If filling in a service station, stop after

the third automatic shut-off of the

nozzle.

Care of the stickers

These styling stickers are treated to give good

resistance to ageing and tearing.

They have been designed to allow you to

customise your vehicle's bodywork.

When using a high pressure jet wash, keep the

end of the lance at least 30 centimetres from

the stickers.

F After refilling, carry out these same

operations in reverse order.
