used products
Avoid prolonged contact of used oil or fluids
with the skin.
Most of these fluids are harmful to health or
indeed very corrosive.
Do not discard used oil or fluids into sewers
or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a CITROËN dealer
or consult the maintenance and warranty
guide contained in the handbook pack.
To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.
changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fluids recommended by the
manufacturer, which fulfil DOT4 standards.
The level must be between the MIn and
MA
x marks on the reservoir.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible.
If you have to remove/refit the engine
styling cover, handle it with care to
avoid damaging the fixing clips.

There are two marks on
the dipstick:
Oil change
It is imperative that this is carried out at the
intervals specified in the manufacturer's
servicing schedule. Ask for advice at at
CITROËN dealer.
Remove the dipstick before filling.
Check the level after filling (never exceed
the maximum mark).
Screw the cap back onto the sump before
closing the bonnet.
Viscosity selection
When topping-up, the oil selected must meet
the manufacturer's requirements.
Warning lamps
Checking by means of the warning
lamps on the instrument panel is
described in the "Ready to go -
Instruments and controls" section.
A
= maximum
If you fill past this mark,
contact a CITROËN dealer
or a qualified workshop.
B = minimum
Never allow the level to fall
below this mark.
Oil level
Check the level regularly and top up between
changes. The maximum consumption is
0.5 litre per 600 miles (1
000 km). Check
the level with the vehicle level, engine cold,
using the dipstick.

cooling systemPower steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MI n and
MA
x marks.
For access to the reservoir filler cap, remove
the protective cover by turning its three
fixing screws a quarter turn, then remove the
second cover fitted to the cap.
topping up
The level must be between the
MI n and
MA x marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer or a qualified workshop.
Windscreen wash and headlamp
wash level
Capacity of the reservoir: approximately
5.5 litres.
For access to the reservoir filler cap, pull on
the telescopic filler pipe and unclip the cap.
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
In wintry conditions, the use of an alcohol or
methanol based fluid is recommended.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible.
Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
For access to the header tank filler cap,
remove the protective cover by turning its
three fixing screws a quarter turn.

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.These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.

Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the diesel
filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger
compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.

Oil filter
Brake pads
Brake pad wear depends on the style of
driving, in particular for vehicles which are
used in town, over short distances. It may
be necessary to check the thickness of the
pads, even between services.
Brake disc wear
For any information on checking the brake
disc wear, contact a CITROËN dealer or a
qualified workshop.
Parking brake
Where the parking brake travel is too great
or there is a reduction in the performance
of the system, the parking brake should be
adjusted, even between services.
Have the system checked by a CITROËN
dealer or a qualified workshop.
If this warning lamp comes on,
have the brake pad wear checked
by a CITROËN dealer or a
qualified workshop. In order to avoid damaging the
electrical units, we strongly advise you
not to use high pressure washing to clean
the engine compartment.
After washing the vehicle dampness, or in
winter, ice may form on the brake discs and
pads: braking efficiency may be reduced.
Make some light brake applications to dry
and de-ice the brakes. Only use products recommended by
CITROËN or products of equivalent quality
and specification.
In order to optimise the operation of units as
important as the braking system, CITROËN
selects and offers specific products.
Change the filter regularly, in accordance
with the manufacturer's servicing schedule.

Operating fault
If this alert persists, do not ignore the
warning; it indicates that a fault has occurred
in the exhaust / particle filter system.
Have the whole system checked by a
CITROËN dealer or a qualified workshop.
If there is risk of blockage of the
filter, this warning lamp comes on
in the instrument panel.
Saturation /
r
egeneration
Because of the higher exhaust
gas temperature resulting from the
normal operation of the particle filter, it is
recommended that you do not park the
vehicle over inflammable materials (grass,
dry leaves, pine needles,

...) so as to avoid
any risk of fire.
Particle filter system (diesel)
An addition to the catalytic converter, this
filter makes an active contribution to the
preservation of air quality by the retaining
of the unburnt pollutant particles. Black
exhaust fumes are thus no longer emitted.
Operation
This filter, fitted in the exhaust system,
accumulates particles of soot. The engine
management unit controls the automatic
periodic elimination of the soot particles
(regeneration).
The regeneration procedure is invoked
according to the quantity of particles
accumulated and the driving conditions
of the vehicle. During this phase, you
may notice some unusual phenomena -
increased idling speed, cooling fan running,
increase in smoke and higher exhaust gas
temperature
- which does not affect the
operation of the vehicle or the environment. 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. To regenerate the filter, it is advised to drive
as soon as possible, when traffic conditions
and the law permit, at a speed of at least

40 mph (around 60 km/h), with an engine
speed above 2 000 rpm for about fifteen
minutes (until the warning lamp and/or the
message disappears).
If possible, avoid switching off the engine
before the end of regeneration of the
filter; repeated interruptions could cause
premature deterioration of the engine oil. It
is not recommended to end regeneration of
the filter with the vehicle stationary.
This alert tells you that the particle filter
is starting to fill up (in conditions of urban
driving of exceptionally long duration: low
speeds, traffic jams etc.)

In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited
to low or minus temperatures. With Stop & Start, never refuel with
the system in STOP mode; you must
switch off the ignition with the key. When the fuel tank level E
(Empty) is reached, this warning
lamp comes on.
You then have around 10 to
12 litres in the reserve, depending on the
capacity of the tank, the engine type, the
driving conditions and the profile of the road.
Refuel without delay to avoid running out of
fuel.
The capacity of the fuel tank is
approximately 90 litres.
Fuel tanks of different capacities, 60 and
120 litres, may be fitted. The fuel tank must be filled with the engine
off.
-
Open the fuel filler flap.
-

Support the black cap with one hand.
-

With the other hand, insert the key
, then
turn it anticlockwise.
-
Remove the black cap and hook it onto

the clip located on the inside of the flap.
A label affixed to the inside of the flap
reminds you of the type of fuel to be used.
When filling the fuel tank, do not continue
after the 3rd cut-off of the nozzle. This could
cause malfunctions.
-
After filling the fuel tank, lock the black

cap and close the flap.

A nd AdB L u E® AddItIVE
AdBlue® is the brand name of the solution
needed for operation of the SCR system.
BlueHDI vehicles have a specific AdBlue
®
additive tank with a capacity of 15 litres.
It has an exterior filler located behind the
fuel filler flap below the fuel filler cap and
closed with a blue filler cap.
The objective of BlueHDi is to reduce by
up to 90% the emissions of NOx (nitrous
oxides) in the air, using a system that
converts NOx into water vapour and nitrogen
in a dedicated catalytic converter: SCR
(Selective Catalytic Reduction).
This objective meets the "Euro 6" emissions
standard adopted by the European Union
aimed at limiting the emissions of pollutants
from internal combustion engines.
The SCR technology used on BlueHDi
engines involves the injection of AdBlue
®
fluid into the exhaust system. This operation can also be carried out
by a CITROËN dealer or a qualified
workshop.
Scr technology
Filling of the AdBlue® tank can be done
using:
-

5 or 10 litres containers equipped with a

10 centimetre filler tube or the filling kit
available from CITROËN dealers,
-

1.89 litre botles that are screwed onto

the filler neck, available from CITROËN
dealers,
-

or when at a fuel filling station equipped

with a special AdBlue
® delivery pump for
heavy or light vehicles.

Good practice
While the quantity of AdBlue® in the additive
tank
is sufficient, no information is displayed.
On the other hand, once the additive level
drops to the quantity needed for a range
of 1 500 miles (2 400 km) driving, you
are warned by different temporary signals
(warning lamp, message, audible signal).
As more miles are covered, these signals
intensify and the message becomes
permanent.
Filling the additive tank
For light vehicles, 5 or 10 litre containers
and 1.89 litre (1/2 US gallon) bottles are
available from CITROËN dealers.
If you want to fill the AdBlue
® tank yourself,
ensure that you have a suitable filler pipe,
which may or may not be supplied with the
additive container. When the AdBlue® tank is empty,
restarting becomes impossible.
It is strongly recommended that you do
not wait for the successive alerts before
topping-up the AdBlue
® tank, but do this as
soon as possible.
