For access to the reser voir filler cap, remove
the protective cover by turning its three fixing
screws a quarter turn, then remove the second
cover fitted to the cap.
Engine coolant level
Check the coolant level regularly.
It is normal to top up this fluid
between two services.
Check the coolant level regularly,
according to the use made of your vehicle
(every 3,000
miles (5,000 km)/3 months);
if necessary, top up using coolant
recommended by the manufacturer.
The check and top up must only be done
with the engine cold.
A low coolant level presents a
risk of
serious damage to your engine.
When the engine is hot, the temperature of the
coolant is regulated by the electric fan. This
may operate with the ignition off; furthermore,
because the cooling system is under pressure,
wait for at least one hour after the engine has
stopped before carrying out any work. F

Checks
These operations allow your vehicle to be
kept in good working order. Ask for advice
from a CITROËN dealer or refer to the
manufacturer's service schedule included
in the handbook pack.
Battery
The battery does not require any
maintenance.
However, check regularly that the
terminals are correctly tightened
(models without quick release
terminals) and that the connections
are clean. Models 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.
Filter, air
At the start of winter, have your battery checked
by a CITROËN dealer or a qualified workshop.
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.
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if
necessary .
Filter, passenger
compartment
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component. Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace it twice as often if
necessary
.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
A clogged passenger compartment
filter may have an adverse effect on
the per formance of the air conditioning
system and generate undesirable odours.
As an addition to the catalytic converter,
this filter makes an active contribution to the
preser vation of air quality by retaining unburnt
pollutant particles. Black exhaust fumes are
also eliminated.
7
Practical information

130
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 triggered
depending on the amount of particles
accumulated and the vehicle use conditions.
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. 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, etc.) so as to
avoid any risk of fire.
Saturation/Regeneration
If there is risk of blockage of the
filter, this warning lamp comes on in
the instrument panel.
This alert tells you that the particle filter is
starting to saturate (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
and the law permit, at a
speed of at least
37

mph (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 the filter regeneration;
repeated interruptions could cause premature
deterioration of the engine oil. It is not
recommended to end regeneration of the filter
with the vehicle stationary.
Malfunction
If this alert persists, do not ignore the warning;
it indicates that a fault has occurred in the
exhaust system/particle filter assembly.
Have the whole system 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.
If this warning lamp comes on, have
the brake pad wear checked by
a
CITROËN dealer or a qualified
workshop.
Practical information

131
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN or
a


qualified workshop.
Parking brake
If excessive travel or a loss of
e ffectiveness of this system is
noticed, the parking brake must
be checked, 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 reser voir. 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.
Purging water from the filterThe HDi engines use advanced technology.
All work must be done by personnel that
have had special training, which can be
ensured by going to 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.
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.

To w i n g
General recommendations
Obser ve the legislation in force in your
c o u nt r y.
Ensure that the weight of the towing
vehicle is higher than that of the towed
vehicle.
The driver must remain at the wheel of
the towed vehicle and must have a valid
driving licence.
When towing a
vehicle with all four wheels
on the ground, always use an approved
towbar; rope and straps are prohibited.
The towing vehicle must move off gently.
When the vehicle is towed with its engine
off, there is no longer braking and steering
assistance.
In the following cases, you must always
call on a
professional recovery ser vice:
-

v
ehicle broken down on a motor way or
main road,
-
f

our-wheel drive vehicle,
-

w
hen it is not possible to put the
gearbox into neutral, unlock the
steering, or release the parking brake,
-

t
owing with only two wheels on the
ground,
-

w
here there is no approved towbar
available.
The charging operation must be carried
out in a

ventilated area away from naked
flames or any possible sources of sparks
to eliminate the risk of explosion and fire.
Do not try to charge a

frozen battery: it
must first be thawed out to avoid the risk
of explosion. If the battery has frozen,
before charging it have it checked by
a

specialist who will verify that the internal
components have not been damaged and
that the case is not cracked, which could
mean that there is a

risk of a

leak of toxic
and corrosive acid.
Proceed with a

slow charge at low current
for a

maximum of about 24

hours to avoid
damaging the battery.
Charging the battery using
a battery charger
F Go to the battery located in the front left
f l o o r.
F

D
isconnect the battery.
F

F
ollow the instructions for use provided by
the manufacturer of the charger.
F

R
econnect starting with the negative (-)
terminal.
F

C
heck the condition of the terminals and
clamps. If they are covered with sulphate
(whitish or greenish deposits), disconnect
them and clean them all.
After refitting of the battery by a
CITROËN
dealer or a
qualified workshop, the Stop
& Start system will only be active after
a


continuous period of immobilisation
of the vehicle, a period which depends
on the climatic conditions and the state
of charge of the battery (up to about
8


h o u r s).
The presence of this label, in particular
with the Stop & Start system, indicates
the use of a
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.
