CHECKS
To check the main levels
and certain components,
in accordance with the
manufacturer's servicing schedule,
refer to the pages of the Maintenance
and Warranty Guide which correspond
to your vehicle's engine.
Only use products recommended
by CITROËN or products
of equivalent quality and
specifi cation.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers
specifi c products.
In order to avoid damaging the
electrical units, high pressure washing
to clean the engine compartment is
strictly prohibited.
Oil filter
Change the fi lter regularly, in
accordance with the servicing
schedule. Refer to the servicing booklet to
fi nd out the replacement interval
for these components.
Depending on the environment
(dusty atmosphere...) and the use of
the vehicle (urban driving...), change
them twice as often if necessary.
Refer to the "Under the bonnet" section
of chapter 6. Particle emission filter (Diesel)
It is imperative that particle emission
fi lter maintenance is carried out by a
CITROËN dealer.
On acceleration after the vehicle has
been running for a prolonged period
at very low speed or at idle, you may,
in exceptional circumstances, notice
the emission of water vapour at the
exhaust. This water vapour does not
have any adverse effect on vehicle
handling or the environment.
Battery
At the start of winter, have your battery
checked by a CITROËN dealer.
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.
Unless there is a leak on the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.
Brake disc/drum wear status
For any information relating to
checking the brake disc/drum wear
status, contact a CITROËN dealer.
Handbrake
Where the handbrake travel is too
great or there is a reduction in the
performance of the system, the
handbrake should be adjusted, even
between services.
Have the system checked by a
CITROËN dealer. Carbon filter and passenger
compartment filter
The carbon fi lter permits continuous
and effective fi ltering of dust.
If the passenger compartment fi lter
becomes clogged, this may reduce
the performance of the air conditioning
system and generate unpleasant
odours.
We recommend the use of a combined
passenger compartment fi lter. By
means of its second special active
fi lter, it contributes to the purifi cation
of the air breathed by the occupants
and to the cleanness of the passenger
compartment (reduction of allergic
symptoms, unpleasant odours and
greasy deposits).
Manual gearbox
Have the level checked in accordance with
the manufacturer's servicing schedule.

Battery
ECONOMY MODE FUNCTION
After the engine has stopped, with
the key in the ignition position, certain
functions (windscreen wiper, electric
windows, courtesy lights, audio
equipment, etc.) can only be used for a
cumulative duration of thirty minutes, to
prevent discharging the battery.
Once the thirty minutes are over, the
message "Economy mode active"
appears on the display and the active
functions are put on standby.
To resume the use of these functions
immediately, start the engine and let it
run for a few seconds.
A fl at battery will prevent the engine
from starting.
To charge the battery using
a battery charger
- disconnect the battery,
- follow the instructions for use
given by the battery charger
manufacturer,
- reconnect starting with the negative (-) terminal,
- check that the terminals and connectors are clean. If they are
covered with sulphate (white or
greenish deposit), disconnect them
and clean them.
BATTERY
This is housed in a compartment
located underneath the fl oor, in front of
the driver's seat.
Before disconnecting the battery, you
must wait for 2 minutes after switching
off the ignition.
Never disconnect a terminal when the
engine is running.
Never charge a battery without fi rst
disconnecting the terminals.
Close the sunroof and the windows
before disconnecting the battery. If
they do not operate normally following
reconnection of the battery, they must
be reinitialised.
It is advisable to disconnect the
battery if the vehicle is not to be used
for a period of more than one month.
After every reconnection of the battery,
switch on the ignition and wait 1 minute
before starting to allow the electronic
systems to be initialised. If slight
diffi culties are experienced after this,
please contact a CITROËN dealer.
The door open monitoring electrical
system consumes power, remember
to close the sliding doors when your
vehicle is parked for long periods.
To start the vehicle from
another battery
- connect the red cable to the positive (+) terminals of the
two batteries,
- connect one end of the green or black cable to the negative (-)
terminal of the slave battery,
- connect the other end of the green or black cable to an earth point on
the broken down vehicle as far as
possible from the battery,
- operate the starter, let the engine run,
- wait for the engine to return to idle, then disconnect the cables. For the sunroofs safety auto-
reverse, refer to the "Accesses"
section of chapter 2. For the electric windows safety
auto-reverse, refer to the "Mirrors
and windows" section of chapter 3.

SOLUTION ANSWER
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode.
The aerial is absent or has been damaged (for exam ple when going through a car wash or into an underground car park).
This phenomenon is normal and does not indicate a failure of the audio equipment.
Have the aerial checked by a CITROËN dealer.
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 if the phenomenon is too frequent and always on the same route.
With the engine off, the audio equipment switches off after a few minutes of use.
When the engine is switched off, the audio equipme nt operating time depends on the battery charge.
The switch-off is normal: the audio equipment switches to economy mode and switches off to prevent discharging of the vehicle's battery.
The stored stations do not function (no sound, 87.5 Mhz is displayed...)
An incorrect waveband is selected. Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on which the stations are stored.
Start the vehicle's engine to increase the battery charge.
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...).
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.
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
