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

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.If this warning lamp comes on,
have the brake pad wear checked
by 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.
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. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
manufacturer's service schedule included in
the handbook pack.
cHEcKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
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.
Oil filter
Change the filter regularly, in accordance
with the manufacturer's service schedule.
Levels and checks

145
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
2. HDi engines uses 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. -
