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.

These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice from a CITROËN
dealer or consult the manufacturer's service
schedule contained in the handbook pack.
Checking by means of the warning
lamps on the instrument panel is
described in the "Ready to go -
Instruments and controls" section.
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 system
Check the coolant level regularly,
according to the use made of your
vehicle (every 3 000 miles or 5 000 kms
/
3

months);
if necessary, top-up using coolant
recommended by the manufacturer.
Topping-up the coolant between services is
normal.
The check and top-up must be done with the
engine cold.
A low coolant level presents the risk of
serious damage to your engine. For access to the header tank filler cap,
remove the protective cover by turning its
three fixing screws a quarter turn.
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.
To avoid the risk of scalding, with a cloth
around the cap, slacken the cap by a quarter
turn to release the pressure. When the
pressure has dropped, remove the cap and
top-up the level with coolant.changing the brake fluid
The brake fluid must be changed at
the intervals stated, according to the
manufacturer's service schedule.
Use brake fluid recommended by the
manufacturer, meeting the DOT4 standard.
The level must be between the MI
n 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. Engine oil grade
When topping-up, the oil selected must meet
the manufacturer's requirements. Oil change
It is imperative that this is carried out at the
intervals specified in the manufacturer's
service schedule. Ask for advice from a
CITROËN dealer.
Refill the engine oil using the procedure
described for topping-up.
Check the level after filling (never exceed
the maximum mark).
Levels and checks

143
topping-up
The level must be between the MI n and
MA
x marks on the expansion bottle.
As close as possible to the MA
x mark is
recommended.
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.
Power 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.
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.

Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.
Good practice
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.
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 bled to remove water.
Y

ou can also bleed the fuel filter
regularly, every time the engine oil
is changed.
Bleeding water from the filter
-

Connect a transparent pipe to the head

of the bleed screw 1 .
-

Place the other end of the transparent

pipe in a recipient.
-

Slacken the bleed screw

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 and the engine.
Refuel without delay to avoid running out of
fuel.
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.
BlueH d i and AdBlue
The blue cap is only present on BlueHDi
Diesel versions.
