Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.

CITROËN dealer.
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. O i l s p e c i fi c a t i o n
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Fluid change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation.

too long may cause a loss of braking

Coolant level
Draining the system
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the
manufacturer's recommendations.
The reading will only be
correct if the vehicle is on
level ground and the engine
has been off for more than
15 minutes.
The check is carried out either when
the ignition is switched on using the
oil level indicator on the instrument
panel, or using the dipstick.
Between two oil changes, the con-
sumption should not exceed 0.5 litre
per 600 miles (approx. 1 000 km).
Check this level also between each
scheduled service and before long
journeys. T h e b r a k e fl u i d l e v e l s h o u l d
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the tem-
perature of the coolant is regulated
by the fan. This can operate with the
ignition off.
O n v e h i c l e s w h i c h a r e fi t t e d w i t h

gine is cold.
In addition, as the cooling system is
pressurised, wait at least one hour
after switching off the engine before
carrying out any work.
To avoid any risk of scalding, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction

Topping up
This additive must be topped up by
a CITROËN dealer without delay.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection. Air filter and passenger
compartment filter
Refer to the Maintenance
and Warranty Guide for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" paragraph).
A c l o g g e d c a b i n fi l t e r m a y h a v e a n
adverse effect on the performance
of the air conditioning system and
generate undesirable odours.
Oil filter
R e p l a c e t h e o i l fi l t e r e a c h
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
c o n v e r t e r , t h i s fi l t e r m a k e s a n a c -
tive contribution to the preservation
of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving
at very low speeds, you may oc-
casionally notice water vapour be-
ing emitted from the exhaust when
accelerating. This is of no conse-
quence to the running of the vehicle
or to the environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the serv-
ice warning lamp.
This alert tells you that the particle
fi l t e r i s s t a r t i n g t o fi l l u p ( i n c o n d i -

tionally long duration: low speeds,

If this alert persists, consult a
CITROËN dealer.

Guide for details of the replacement in-
terval for this component.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles 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
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6 - s p e e d e l e c t r o n i c g e a r b o x
system The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake If a loss of effectiveness
of this system is noticed,
the parking brake must be
checked, even between
two services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent qual-
i t y a n d s p e c i fi c a t i o n s .
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
f e r s v e r y s p e c i fi c p r o d u c t s .
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
