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.

Refer to the manufacturer's service schedule
for the checking 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.

AdBlue® fluid 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.

When switching on the ignition, this 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 fluid has been
topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® topped-up.
You can also top-up the tank yourself.
For more information on AdBlue
® and the SCR
system, and in particular on topping-up the
AdBlue
®, refer to the corresponding section. When switching on the ignition, this 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 fluid has been topped-up.
Go to a CITROËN dealer or a qualified
workshop to have the AdBlue
® topped-up.
You can also top-up the tank yourself.
Other wise you will not be able to restart your
engine. When switching on the ignition, this 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.
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.
Remaining range between 350 and 1500 miles (600 and 2 400 km)Remaining range between 0 and 350 miles (0 and 600 km)Breakdown related to a lack of AdBlue®

In the event of a fault with the SCR emissions control system
These warning lamps come 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 it is a temporary fault, the alert
disappears during the next journey,
after self-diagnosis of the SCR system.
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. In the event of the detection of a fault
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), these warning lamps come on,
accompanied by an audible signal and the
display of a message (e.g.: "Emissions fault:
Starting prevented in 150 miles") indicating
the remaining range expressed 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.
Other wise, you will not be able to restart your
engine.
