Practical information
A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
Screenwash and headlamp
washer fluid
To check the level or top up this fluid on
vehicles fitted with headlamp washers,
immobilise the vehicle and switch off the engine.
Reservoir capacity: approximately 5.5 litres.


To access the filler cap, pull the telescopic filler
neck and unclip the cap.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).
AdBlue (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular on the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them 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
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
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.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Passenger compartment

Practical information
7A clogged passenger compartment filter can adversely affect air conditioning
system performance and generate
undesirable odours.
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
In addition to the catalytic converter, this filter
actively contributes to the preservation of
air quality by trapping the unburnt pollutant
particles. Black exhaust fumes are therefore not
emitted.
Operation
This filter, inserted into the exhaust system,
accumulates the carbonaceous particles. The
engine management computer automatically
and periodically manages the removal of
carbonaceous particles (regeneration).
The regeneration procedure is triggered
according to the amount of accumulated
particles and the conditions of use of the vehicle.
During this phase, you may notice certain
phenomena - accelerated idling, triggering of
the cooling fan, increased smoke and increased
temperature at the exhaust - which have no
impact on the operation of the vehicle and the
environment.
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 while
accelerating. This has no impact on the
vehicle’s behaviour and the environment.
Due to the high exhaust temperatures
caused by the normal operation of the
particle filter, it is recommended not to park
the vehicle on flammable materials (grass, dry
leaves, pine needles, etc.) to avoid any risk of
fire.
Saturation/Regeneration
If there is a risk of clogging, this warning
lamp comes on, accompanied by a
message on the instrument panel display.
This warning is due to the start of saturation of
the particle filter (exceptionally long urban driving
conditions: reduced speed, traffic jams, etc.).
In order to regenerate the filter, it is
recommended to drive as soon as possible -
when traffic conditions and regulations permit
- at a speed of at least 37 mph (60 km/h), with
an engine speed above 2,000 rpm for about
15 minutes (until the warning lamp and/or the
message disappear).
If possible, avoid switching off the engine
before the end of filter regeneration; repeated
interruptions can lead to early deterioration of the
engine oil. It is not recommended to terminate
the filter regeneration with the vehicle stationary.
Malfunction
If this alert persists, do not ignore this warning;
this indicates that a malfunction has occurred in
the exhaust system/particle filter assembly.
Have the assembly checked by a CITROËN
dealer or a qualified workshop.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
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.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
If this warning lamp comes on, have the
brake pads checked by a CITROËN
dealer or a qualified workshop.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.

Practical information
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Diesel fuel filter
The Diesel fuel filter is located under the bonnet,
close to the brake fluid reservoir.
If this warning lamp comes on, the filter
must be purged to remove water.
You can also purge the fuel filter regularly, every
time the engine oil is changed.
Bleeding the water in the filter

► Couple a clear hose to the bleed screw
1head.
► Place the other end of the clear hose in a
container.
► Loosen bleed screw 2.
► Switch on the ignition.
► Wait for the scavenge pump to stop.
► Switch off the ignition.
► Tighten bleed screw 2.
► Remove, then drain the clear hose and the
container.
► Start the engine.
► Check that there are no leaks.
HDi engines make use of advanced
technology. Any intervention requires a
special qualification guaranteed by the
CITROËN dealer network or a qualified
workshop .
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
