Checks
12 V battery
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.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
Air filter and passenger compartment filter
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary.
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours. Replace the oil filter each time the
engine oil is changed.
Oil filter
Refer to the manufacturer's service schedule
for details of the replacement interval for this
component.

Particle filter system (Diesel)
Complementary to the catalytic converter,
this filter makes an active contribution to the
preservation of air quality by trapping unburnt
pollutant particles. Black exhaust fumes are
thus no longer emitted.
After prolonged idling or driving at very low
speeds, you may occasionally notice water
vapour being emitted from the exhaust when
accelerating. This is of no consequence to the
running of the vehicle or to the environment.
If there is risk of blockage, a message
appears in the instrument panel screen,
accompanied by an audible signal and
illumination of the service warning lamp.
This alert tells you that the particle filter
is approaching saturation (in conditions
of urban driving of exceptionally long
duration: low speeds, traffic jams etc.)
To regenerate the filter, it is advised to
drive as soon as possible, when traffic
conditions permit, at a speed of 40 mph
(around 60 km/h) or more for at least
five minutes (until the alert message
disappears).
If this alert persists, contact a CITROËN
dealer or a qualified workshop.

Brake pads
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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Manual parking brake
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.
If 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.
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.
For more information on the
Electric parking brake , refer to the
corresponding section.

AdBlue® 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
per formance 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.
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. The AdBlue
® is held in a special tank with
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.
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.
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
®. Once the AdBlue
® tank is empty, a
s
ystem 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.
In either case, a range indicator gives
you the distance you can travel before
the vehicle is immobilised.

Precautions in use
AdBlue® is a 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 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).
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. Use only AdBlue
® fluid that meets the
ISO

22241 standard.
Never dilute AdBlue
® with water.
Never pour AdBlue® into the Diesel fuel
tank.
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 litre containers
from a CITROËN

dealer or a qualified
workshop.
Never top-up from an AdBlue
®
dispenser reserved for heavy goods
vehicles.
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.
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.
If you envisage topping-up yourself, please
read the following warnings carefully.

Charging the battery using a battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances it may be necessary to
charge the battery:
-
i
f you use your vehicle essentially for short
journeys,
-

i
f the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
If you envisage charging your vehicle's
battery yourself, use only a charger
compatible with lead-acid batteries of a
nominal voltage of 12 V.
Never try to charge a frozen battery.
If the battery has been frozen, have
it checked by a CITROËN dealer or a
qualified workshop, who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
It is not necessary to disconnect the
battery. Follow the instructions for use provided
by the manufacturer of the charger.
Never reverse polarities.
If this label is present, it is essential
to use only a 12 V charger, to avoid
