Quality of the fuel used for
petrol engines

The petrol engines are perfectly com-
patible with E10 or E24 type petrol bio-
fuels (containing 10 % or 24 % etha-
nol), conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for ve-
hicles marketed for the use of this type
of fuel (BioFlex vehicles). The quality of
the ethanol must comply with European
standard EN 15293.
For Brazil only, special vehicles are
marketed to run on fuels containing up
to 100 % ethanol (E100 type).













Quality of the fuel used for
Diesel engines

The Diesel engines are perfectly com-
patible with biofuels which conform to
current and future European standards
(Diesel fuel which complies with stan-
dard EN 590 mixed with a biofuel which
complies with standard EN 14214)
available at the pumps (containing up
to 7 % Fatty Acid Methyl Ester).
The B30 biofuel can be used in certain
Diesel engines; however, this use is sub-
ject to strict application of the special ser-
vicing conditions. Contact a CITROËN
dealer or a qualifi ed workshop.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or dilut-
ed, domestic fuel...) is strictly prohibited
(risk of damage to the engine and fuel
system).
The petrol or Diesel engine of your ve-
hicle is fi tted with a catalytic converter, a
device which helps to reduce the level of
harmful emissions in the exhaust gases.

For petrol engines, the use of un-
leaded fuel is compulsory.

The fi ller neck is narrower, admitting
unleaded petrol nozzles only.


Fuel supply cut-off

Your vehicle is equipped with a safety
device which cuts off the fuel supply in
the event of a collision.

CHECKING LEVELS

Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).

Oil level


Engine oil change
Refer to the servicing booklet for the
interval for this operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's
recommendations.



Brake fluid level

The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the servicing booklet for the
interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.



Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.


Coolant level

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 operate with the ig-
nition off.

On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate 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 pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

Changing the coolant

The coolant does not have to be changed.


Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

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.










Additive level (Diesel with
particle emissions filter)
According to your version of instrument
panel, the additive reservoir low level is
indicated by:

Topping up
The reservoir must be topped up with-
out delay by a CITROËN dealer or a
qualifi ed workshop.


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that the particle emissions fi l-
ter additive level is too low,

- fi xed illumination of the
service warning lamp, ac-
companied by an audible
signal and a message that
the particle emissions fi lter additive level is too low. or

Screenwash/headlamp wash
level
Specifi cation of the fl uid
To ensure optimum cleaning and to
avoid freezing, the fl uid should never be
topped up or replaced by plain water.

CHECKS

Unless otherwise indicated, check
these components in accordance with
the servicing booklet and according to
your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed workshop.


Battery

The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion 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 compo-
nents.

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 component.










Particle emission filter (Diesel)

According to your version of instrument
panel, the start of saturation of the par-
ticle emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that there is a risk of blockage
of the particle emissions fi lter,






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery.

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 l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.
As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
On a new vehicle, the fi rst opera-
tions of regeneration of the particle
emissions fi lter may be accom-
panied by the smell of "burning",
which is perfectly normal.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. or

-
temporary illumination of
the service warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of
the particle emissions fi lter.

Electric parking brake


This system does not require any
routine servicing. However, in
the event of a problem, have the
system checked by a CITROËN
dealer or a qualifi ed workshop.

For more information, see "Driving - Electric parking brake - § Operating faults".
















Brake pads

Brake disc wear

If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be done by
a CITROËN dealer or a qualifi ed work-
shop.

















Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.

In order to optimise the opera-
tion 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 compart-
ment is strictly prohibited
.



Manual parking brake

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop. Brake wear depends on the
style of driving, particularly 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 system, a
drop in the brake fl uid level indicates
that the brake pads are worn.
