Screenwash and headlamp
wash fluid
Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with plain water.
Reservoir capacities:
- screenwash: approximately 3 litres,
- screenwash and headlamp wash: approximately 6 litres. Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
lighting of the service warning lamp,
accompanied by an audible warning
and a message on the multifunction
screen.
Topping up
This additive must be topped up by
a CITROËN dealer without delay.
Used products
Avoid prolonged contact of
used oil or fl uids with the
skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or
fl uids into sewers or onto
the ground.
Take used oil to a CITROËN deal-
er (France) or an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
minimum level of this fl uid is
indicated by an audible signal
and a message on the multifunction
screen.
Top up the level when you next stop
the vehicle.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Warranty and Maintenance
Record 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 Warranty and
Maintenance Record 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
fi lter may have an adverse effect on
the performance of the air condition-
ing system and generate undesirable
odours.
Oil filter
Replace the oil fi lter each
time the engine oil is
changed. Particle filter system (Diesel)
Complementary to the catalytic
converter, this fi lter makes an ac-
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 message
appears on the multifunction screen,
accompanied by an audible 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 exception-
ally 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 Warranty and Maintenance
Record 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 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
drop in the brake fl uid level indicates
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6-speed electronic gearbox
system The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire 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 qual-
ity and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .

Warranty Guide for the details of the
level checking interval for this com-
ponent.

Refi tting the wheel
Dimension of the spare wheel
If your spare wheel is of different di-
mensions to those on the vehicle
(identifi ed by a label), it is essential
to use it only on a temporary basis,
to drive not above 50 mph (80 km/h)
and to have the original wheel refi tted
as soon as possible.
Switch on your hazard
warning lamps.

Ensure
that
occupants
get out of the vehicle and wait in
a safe location.

Never get underneath the vehicle
if it is supported only by the jack;
use an axle stand.

The jack is designed specifi cally
for your vehicle, do not use it for
other applications.

The wheel should be correctly
positioned fl at in the centre of
its well. Aluminium wheels
If your vehicle is equipped with al-
uminium wheels and a steel spare
wheel, then if fi tting the latter it is
normal to note that the heads of the
wheel bolts do not come to bear on
the wheel rim.
The steel spare wheel is secured
by the conical tapering of the wheel
bolts’ shafts, see diagram.
When refi tting the aluminium wheel,
ensure that the wheel bolt heads are
in undamaged condition.

 Refi t the wheel in place.

 Undo the yellow central screw by
a few turns, then position it at the
centre of the wheel.

 Do up the central screw until tight
so that the wheel is securely re-
tained in place.
Refi t the repaired original wheel
as soon as possible.

With a spare wheel fi tted, drive
with caution.
