Screenwash and headlamp wash
fl uid

Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be
topped up with or replaced with plain
water.











Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by
illumination of the service warning
lamp, accompanied by an audible
warning and a message in the multi-
function screen.

Topping up
This additive must be topped up by
a CITROËN dealer or a qualifi ed
workshop 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
dealer or a qualifi ed workshop
(France) or to an authorised waste
disposal site.
In the case of vehicles fi tted
with headlamp washers, the
low fl uid level is indicated
by an audible signal and a
message in the screen.
Top up the reservoir when you next
stop the vehicle.









Coolant level

Changing the coolant
The coolant does not have to be
changed.

Fluid specifi cation
The coolant must conform to the
manufacturer's recommendations.

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, un-
screw the cap by two turns to al-
low the pressure to drop. When the
pressure has dropped, remove the
cap and top up the level.

12 V battery

The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical information"
section for details of the precautions
to be taken before disconnecting the
battery and following its reconnection.










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 oc-
casionally notice water vapour be-
ing emitted from the exhaust when
accelerating. This is of no conse-
quence 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 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 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 or a qualifi ed
workshop.





The presence of this label, in par-
ticular with the Stop & Start system,
indicates the use of a specifi c 12 V
lead-acid battery with special tech-
nology and specifi cation, for which
the involvement of a CITROËN
dealer or a qualifi ed workshop is
required when replacing or discon-
necting the battery. Failure to observe this recommen-
dation may shorten the life of the
battery.
Unless otherwise indicated, check
these components in accordance
with the servicing booklet and ac-
cording to your engine.
Otherwise, have them checked by
a CITROËN dealer or a qualifi ed
workshop.





















Air filter and passenger
compartment filter
Refer to the servicing
booklet for details of the
replacement intervals for
these components.
Depending on the environ-
ment (e.g. dusty atmosphere) and
the use of the vehicle (e.g. city driv-
ing), 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 undesir-
able odours.














Oil filter

Replace the oil fi lter each
time the engine oil is
changed.
Refer to the servicing
booklet for details of the
replacement interval for this compo-
nent.

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

PRACTICAL INFORMATION

Temporary use spare wheel
If your vehicle is equipped with a
spare wheel for temporary use only,
when fi tting this it is normal to ob-
serve that the wheel bolts do not
come to bear directly on the wheel
rim.
The spare wheel is secured by the
conical tapering of the wheel bolt’s
shaft.
When refi tting the original wheel, en-
sure that the wheel bolts and wash-
ers are clean and in good condition.


Fitting a wheel



)
Position the wheel with the aid of
the centring guide 3
.

)
Do up the 3 bolts by hand, then
remove the centring guide 3
.
Position the 4 th bolt.

)
Pre-tighten the wheel bolts, us-
ing the wheelbrace 4
.

)

Retract the jack 5
and disengage it.


)
Tighten the wheel bolts, using
the wheelbrace 4
.

)
Ensure that the tyre pressure is
correct.

Under-infl ation detection

Wheels with under-infl ation detection
have tyre pressure sensors. Have repairs
to them carried out by a CITROËN dealer
or a qualifi ed workshop. The spare wheel
does not have a sensor.



Security bolts (alloy wheels)

Each wheel may be equipped with
one security bolt (depending on the
country of sale).
To remove it:


)
remove its protective cover us-
ing of the tool for removing the
chrome covers 2
.

)
use the security bolt socket 6

with the wheelbrace 4
.



Spare wheel dimensions

If your spare wheel has dimensions
different from those of the standard
vehicle wheels (identifi ed by a la-
bel), it is imperative to use the spare
wheel only temporarily, to drive
with caution, not to exceed 50 mph
(80 km/h) and to have the tyre re-
paired and the standard wheel refi t-
ted as soon as possible.


Tyre pressures

These are indicated on the label
on the front left-hand door pillar
(see "Technical Data - Identifi cation
markings").
The wheel bolts are specifi c
to each type of wheel.
If new wheels are fi tted, check with
your CITROËN dealer or a qualifi ed
workshop that the wheel bolts are
compatible with the new wheels.
Make a note of the code number on
the head of the security bolt sock-
et. This will enable you to obtain a
replacement security bolt socket
from your dealer.
