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 (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.
In order to maintain the re-
liability of the engine and

the use of additives in the engine
oil is prohibited. Power steering fluid or power

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and in relation to your en-
gine.
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-
t e r y , r e f e r t o t h e " P r a c t i c a l i n f o r m a t i o n "
section for details of the precautions
to be taken before disconnecting 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 clogged passenger compartment

ing system and generate undesir-
able odours.
Oil filter

changed. Particulate 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 instrument
panel display, accompanied by a
sound signal and lighting of the
service warning lamp.
This alert tells you that the particle

nent.

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).
Automatic gearbox The gearbox does not re-
quire any maintenance
(no oil change). Brake disc wear status
For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.
Handbrake If the handbrake travel is
too long or if a loss of ef-
fectiveness of this system
is noticed, the handbrake
must be adjusted, 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 .
Refer to the Maintenance and
Warranty Guide for the details of the
checking interval for this component.

SOLUTION RESPONSE
The stored stations do not function (no sound, 87.5 Mhz is displayed...)
An incorrect waveband is selected.
The vehicle is too far from the transmitter used by the station listened to or there is no transmitter in the geographical area th rough which the vehicle is travelling.
The environment (hills, buildings, tunnels, baseme nt car parks...) block reception, including in RDS mode.
Press RADIO, select RADIO MENU then AM/FM WAVEBAND to return to the waveband on which the stations are stored.
Activate the RDS function by means of the short-cut menu to enable the system to check whether there is a more powerful transmitter in the geographical area.
This phenomenon is normal and does not indicate a failure of the audio equipment.
Sound cut-outs of 1 to 2 seconds in radio mode.
During this brief sound cut-out, the RDS searches for any frequency permitting better reception of the station. Deactivate the RDS function by means of the short-cut menu if the phenomenon is too frequent and always on the same route.
With the engine off, the system switches off after a few minutes of use.
When the engine is switched off, the system's oper ating time depends on the battery charge. The switch-off is normal: the system switches to economy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
The aerial is absent or has been damaged (for exam ple when going through a car wash or into an underground car park). Have the aerial checked by a CITROËN dealer.
The quality of reception of the radio station listened to gradually deteriorates or the stored stations do not function (no sound, 87.5 Mhz is displayed...).
