12 V battery
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
The presence of this label, in particular with
the Stop & Start system, indicates the use of
a specific 12 V lead-acid battery with special
technology and specification. The involvement
of a CITROËN dealer or a qualified workshop
is essential when replacing or disconnecting
the battery. 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.
Refer to the manufacturer's
service schedule for details of the
replacement intervals for these

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 CITR
oËn
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, refer to the
"Electric parking brake - Operating
faults" section.

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
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.
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. 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. 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: you
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.

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.
In the event of the risk of non-starting related to a lack of AdBlue®
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.
Pressing this button displays the driving range
temporarily.
Above 3 000 miles (5 000 km), the value is not
specified.
The engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank is
e m pt y.
