Maintenance indicator
System which informs the driver
when the next service is due, in ac-
cordance with the manufacturer's
servicing schedule.
The point at which the service is due
is calculated from the last indicator
zero reset. It is determined by two
parameters:
- the distance travelled,
- the time elapsed since the last service. 5 seconds after the ignition is switched
on,
the spanner is switched off ; the
distance recorder resumes its normal
operation. The display then indicates
the total and trip distances.
Less than 620 miles (1 000 km)
remain before the next service is due

Example: 560 miles (900 km) re-
main before the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates: Service overdue
For 5 seconds after the ignition is
switched on,
the spanner fl ashes
to indicate that the service must be
carried out as soon as possible.

Example: the service is overdue by
300 miles/km.
For 5 seconds after the ignition is
switched on, the display indicates:
5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation. The
spanner remains on to indicate that
a service must be carried out soon. 5 seconds after the ignition is
switched on, the distance recorder
resumes its normal operation.
The
spanner remains lit . More than 620 miles (1 000 km)
remain before the next service is due
For 5 seconds after the ignition is
switched on, the spanner symbol-
ising the service operations comes
on. The distance recorder display
line indicates the distance remaining
before the next service is due.

Example: 4 800 miles/km remain
before the next service is due.
For 5 seconds after the ignition is
switched on, the display indicates:
The distance remaining may be
weighted by the time factor, depend-
ing on the driver's driving habits.
Therefore, the spanner may also
come on if you have exceeded the
two year service interval.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding circuit checked by a
CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for de-
tails of the interval for this operation. Oil specifi cation
The oil must correspond to your en-
gine and conform to the manufactur-
er's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.
This fl uid must be changed regularly.
Fluid which has been used exces-
sively may cause a loss of braking
effi ciency.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations
and fulfi l the DOT4 standards.
Coolant level
Draining the circuit
The coolant does not have to be
changed.
Fluid specifi cation
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. The brake fl uid level should
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 temperature of the coolant is
regulated by the fan. This can oper-
ate with the ignition off.

On vehicles which are fi tted with
a particle emission fi lter, the fan
may operate after the vehicle has
been switched off, even if the en-
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,
unscrew the cap by two turns to
allow 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.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and in re-
lation 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,
particularly in summer and winter.
When carrying out work on the
battery, refer to the "Practical
information" 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 servicing
booklet for details of the
replacement intervals for
these components.
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
fi lter may have an adverse effect
on the performance of the air
conditioning system and generate
undesirable odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particulate filter system
(Diesel)
Complementary to the catalytic
converter, this fi lter makes an active
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 notice 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 multifunction
screen, accompanied by a sound
signal and lighting of the service
warning lamp.
This alert tells you that the particle
fi lter is starting to fi ll up (in condi-
tions of urban driving of excep-
tionally long duration: low speeds,
traffi c jams etc.)
To regenerate the fi lter, it is advised
to drive as soon as possible, when
traffi c conditions permit, at a speed
of 40 mph (around 60 km/h) or
more for at least fi ve minutes (until
the alert message disappears).
If this alert persists, consult a
CITROËN dealer.
Refer to the servicing booklet for
details of the replacement interval
for this component.

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of
vehicles 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
drop in the brake fl uid level indicates
that the brake pads are worn.
Manual gearbox
The gearbox does not
require any maintenance
(no oil change).
6-speed electronic gearbox
system
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 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 effectiveness 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 qua-
lity and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and
offers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
