Practical information

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

Brake pads

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.

Brake disc wear

Only use products recommended by
CITROËN or products of equivalent
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.
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.

Manual gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.

Electronic gearbox

The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for details of the checking
interval for this component.

Parking brake

If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.

Checking this system must be done by a
CITROËN dealer or a qualified workshop.

To avoid damaging the electrical units,
never use

a high pressure jet wash in

the engine compartment.

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.

Practical information

AdBlue

additive and SCR system

for BlueHDi Diesel engines

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.

Presentation of the SCR system

Using an additive called AdBlue

containing urea,

a catalytic converter turns up to 85% of nitrous
oxides (NOx) into nitrogen and water, which are
harmless to health and the environment.

Once the AdBlue

tank is empty, a

system required by regulations prevents
starting of the engine.
If the SCR 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.

The AdBlue

additive is held in a special

tank located under the boot at the rear of
the vehicle. It has a capacity of 17 litres: this
provides a driving range of about 12 500 miles
(20 000 km), after which an alert is triggered
warning you when the reserve remaining is
enough for just 1 500 miles (2 400 km).

During each scheduled service of your vehicle
by a CITROËN dealer or a qualified workshop,
the AdBlue

additive tank is refilled in order to

allow normal operation of the SCR system.

If the estimated mileage between two services
is greater than 12 500 miles (20 000 km), we
recommend that you go to a CITROËN dealer
or a qualified workshop to have the necessary
top-up carried out.

177

Practical information

Range indicators

Once the AdBlue

tank is on reserve or after

detection of a fault with the SCR emissions
control system, when the ignition is switched
on, an indicator displays an estimate of the
distance that can be covered, the range, before
engine starting is prevented.
In the event of simultaneous system fault and
low AdBlue

level, the shortest range figure is

the one displayed.

Range greater than 1 500 miles (2 400 km)
When the ignition is switched on, no
information on range is displayed automatically
in the instrument panel.

The engine start prevention system
required by regulations is activated
automatically once the AdBlue

tank is

empty.

In the event of the risk of non-starting related to a lack of AdBlue

Remaining range between 350 and 1500 miles (600 and 2 400 km)

When switching on the ignition, the
UREA warning lamp comes on, accompanied
by an audible signal and the display of a
message (e.g.: "Top up emissions additive:
Starting prevented in 900 miles") indicating
the remaining range expressed in miles or
kilometres.
When driving, the message is displayed every
200 miles (300 km) until the additive tank has
been topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue

tank topped-up.

You can also top-up the tank yourself.
For more information on topping-up the
AdBlue

additive, refer to the corresponding

section.

178

Practical information

Remaining range between 0 and 350 miles (0 and 600 km)

Breakdown related to a lack of AdBlue

additive

To be able to start the engine,
we recommend that you call on
a CITROËN dealer or a qualified
workshop for the top-up required.
If you carry out the top-up yourself, it
is essential to add at least 3.8 litres of
AdBlue

to the tank.

When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of a message (e.g. "Top
up emissions additive: Starting prevented in
350 miles") indicating the remaining range
expressed in miles or kilometres.
When driving, the message is displayed every
30 seconds until the additive tank has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue

tank topped-up.

You can also top-up the tank yourself.
Otherwise you will not be able to restart your
engine.

When switching on the ignition, the SERVICE
warning lamp comes on and the UREA warning
lamp flashes, accompanied by an audible
signal and the display of the message "Top up
emissions additive: Starting prevented".
The AdBlue

tank is empty: the system required

by regulations prevents engine starting.

For more information on topping-up the
AdBlue

additive, refer to the corresponding

section.

179

Practical information

In the event of a fault with the SCR emissions control system

In the event of the detection
of a fault

During an authorised driving phase (between
650 miles and 0 miles) (1 100 km and 0 km)

A system that prevents engine starting is activated automatically from 650 miles (1 100 km) after confirmation of a fault with the SCR emissions
control system. Have the system checked by a CITROËN dealer or a qualified workshop as soon as possible.

If it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.

The UREA, SERVICE and diagnostic warning
lamps comes on, accompanied by an audible
signal and the display of the message
"Emissions fault".
The alert is triggered when driving when the
fault is detected for the first time, then when
switching on the ignition for subsequent
journeys, while the fault persists.

If a fault with the SCR system is confirmed (after
30 miles (50 km) covered with the permanent
display of the message signalling a fault), the
SERVICE and engine diagnostic warning lamps
come on and the UREA warning lamp flashes,
accompanied by an audible signal and the
display of a message (e.g.: "Emissions fault:
Starting prevented in 150 miles") indicating the
remaining range express in miles or kilometres.
While driving, the message is displayed every
30 seconds while the fault with the SCR system
persists.
The alert is repeated when switching on the
ignition.
You should go to a CITROËN dealer or a
qualified workshop as soon as possible.
Otherwise, you will not be able to restart your
engine.

Starting prevented

To be able to start the engine, you must call on
a CITROËN dealer or a qualified workshop.

You have exceeded the authorised
driving limit: the starting prevention
system inhibits engine starting.

Every time the ignition is switched on, the SERVICE
and engine diagnostic warning lamps come on and
the UREA warning lamp flashes, accompanied by
an audible signal and the display of the message
"Emissions fault: Starting prevented".

Practical information

Freezing of the AdBlue

additive

The AdBlue

additive 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.

Topping-up the AdBlue

additive

Precautions in use

Filling the AdBlue

tank is an operation

included in every routine service on your
vehicle by a CITROËN dealer or a qualified
workshop.
Nevertheless, given the capacity of the tank,
it may be necessary to top-up the additive
between services, more particularly if an alert
(warning lamps and a message) signals the
requirement.
You can got to a CITROËN dealer or a qualified
workshop.
If you envisage topping-up yourself, please
read the following warnings carefully.

Keep AdBlue

out of the reach of

children, in its original bottle.
Never transfer AdBlue

to another

container: it would lose its purity.

Never dilute the additive with water.
Never pour the additive into the Diesel
fuel tank.

Never top-up from an AdBlue

dispenser reserved for heavy goods
vehicles.

Use only AdBlue

additive that meets the

ISO 22241 standard.

The supply in a non-drip bottle simplifies
topping-up. You can obtain 1.89 litre (half a US
gallon) bottles from a CITROËN dealer or a
qualified workshop.

The AdBlue

additive is an urea-based

solution. This liquid is non-flammable,
colourless and odourless (kept in a cool area).
In the event of contact with the skin, wash
the affected area with soap and 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 ambient
temperature, for example), the risk of release
of ammonia cannot be excluded: do not inhale
the product. Ammonia vapour has an irritant
effect on mucous membranes (eyes, nose and
throat).

181

Practical information

Recommendations on storage

Never store bottles of AdBlue

in your

vehicle.

Procedure

Switch off the ignition and remove the key.

For access to the AdBlue

tank, raise the

boot carpet then, depending on equipment,
lift out the spare wheel and/or the
storage box.

Without pressing, turn the black cap a

quarter turn anti-clockwise and lift it off.

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.
Under these conditions, the additive can be
kept for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.

Before topping-up, 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

so 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 a 6

of a turn anti-

clockwise.

Lift off the cap.

182

Practical information

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.

Important

: if your vehicle's AdBlue

tank is completely empty - which is
confirmed by the alert messages and
the impossibility of starting the engine,
you must add at least 3.8 litres (so
two 1.89 litre bottles).

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.

Important: in the event of a top-up
after a breakdown because of a lack
of additive

, signalled by the message

"Top up emissions additive: Starting
prevented", you must wait around
5 minutes before switching on the ignition,
without opening the driver's door,
locking the vehicle or introducing the
key into the ignition switch

Switch on the ignition, then, after
10 seconds, start the engine.

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.

After emptying the bottle, wipe away any

spillage around the tank filler using a damp
cloth.

Refit the blue cap to the tank and turn it a

of a turn clockwise, to its stop.

Refit the black cap and turn it a quarter of

a turn clockwise without pressing. Ensure
that the indicator on the cap lines up with
the indicator on the support.

Depending on equipment, return the spare

wheel and/or the storage box to the bottom
of the boot.

Refit the boot carpet and close the tailgate.
