CITROËN dealer.
Oil level
Draining the engine
Refer to the servicing booklet for de-
tails of the interval 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
Draining the circuit
Refer to the servicing booklet for de-
tails of the interval for this operation.

Coolant level
Draining the circuit
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 temperature of the coolant is
regulated by the fan. This can oper-
ate with the ignition off.

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
b a t t e r y , r e f e r t o t h e " P r a c t i c a l
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).

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

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
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).
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 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-
l 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

To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
