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

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.

adb lue® 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 ad
blue
® 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 ad blue
® 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. o
nce the a db lue
® 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 a db lue® 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 ad blue
® 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
