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” section).
A clogged passenger compartment

odours.
Oil filter

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 occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence 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 an
audible signal and lighting of the
service warning lamp.
This alert tells you that the particle

If this alert persists, consult a
CITROËN dealer.

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
require any maintenance
(no oil change).
Automatic gearbox The gearbox does not
require 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 quality
a n d s p e c i fi c a t i o n s .
Do not use a dry cloth with an abra-
sive product for the maintenance of
aluminium parts; use a sponge and
soapy water.
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 level checking interval for this com-
ponent.
Refer to the Warranty and
Maintenance Record for details of
the level checking interval for this

SOLUTION ANSWER
The stored stations do not function ( n o s o u n d , 8 7 . 5 M h z i s d i s p l a y e d . . . ) .
An incorrect waveband is selected.
The quality of reception of the radio station listened to gradually deteriorates or the stored stations do not function (no s o u n d , 8 7 . 5 M h z i s d i s p l a y e d . . . ) .
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.
Press RADIO, select Radio Menu then "Waveband" to return to the waveband on which the stations are stored.
The vehicle is too far from the transmitter used by the station listened to or there is no transmitter in the geographical area through which the vehicle is travelling.
T h e e n v i r o n m e n t ( h i l l s , b u i l d i n g s , t u n n e l s , b a s e m e n t c a r p a r k s . . . ) b l o c k reception, including in RDS mode.
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.
T h e s w i t c h - o f f i s n o r m a l : t h e s y s t e m s w i t c h e s t o e c o n o m y m o d e a n d switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
This phenomenon is normal and does not indicate a failure of the audio equipment.
Have the aerial checked by a CITROËN dealer. The aerial is absent or has been damaged (for exam ple when going through a c a r w a s h o r i n t o a n u n d e r g r o u n d c a r p a r k ) .
