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
details of the interval for this opera-
tion. Oil specifi cation
The oil must correspond to your
engine and conform to the manufac-
turer's recommendations.
Brake fluid level
Draining the circuit
Refer to the servicing booklet for
details of the interval for this opera-
tion.
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 tem-
perature of the coolant is regulated
by the fan. This can operate 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
engine 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
reliability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

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 quality
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 .
