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.Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
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.
12 V battery
When carrying out work on the battery, refer
to the "12 V battery" section for details of the
precautions to be taken before disconnecting
the battery and following its reconnection.
The battery does not require any maintenance.
However, check that the terminals are clean
and correctly tightened, particularly in summer
and winter.
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.
Checks

Particle filter (Diesel)
On a new vehicle, the first operations
of regeneration of the particle filter
may be accompanied by the smell of
"burning", which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
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.According to your version of instrument panel, the start of
saturation of the particle emissions filter is indicated by:
Electronic gearbox
The gearbox does not require any
maintenance (no oil change).

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.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.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between two
services.
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.
For more information, refer to the "Electric
parking brake - Operating faults" section.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Checks

Once the AdBlue® tank is empty,
a s
ystem 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.
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.

251
The engine start prevention system
required by regulations is activated
automatically once the AdBlue
® tank
is empty.
Range indicators
When switching on the ignition, an indicator
gives an estimate of the distance that can
be travelled with your vehicle before engine
starting is automatically prevented, once the
vehicle starts using the reserve of AdBlue
® or
after a fault is detected with the SCR system.
In the event of simultaneous system fault and
low AdBlue
® level, the shortest range 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.

Checks

In the event of a fault with the the SCR emissions control system
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.
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. In the event of the detection of a fault
If it is a temporary fault, the alert
disappears during the next journey,
after a self diagnosis test of the SCR
emissions control system. 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 temporary display in the instrument
panel of "NO START IN" and a distance,
indicating the remaining range express in
miles or kilometres before engine starting is
prevented
- (e.g.: "NO START IN 350 miles"
means "Starting will be prevented in 350 miles"). During an authorised driving phase
(between 650 miles and 0 miles) (1 100 km and 0 km)
