Quality of the fuel used for
petrol engines

The petrol engines are perfectly com-
patible with E10 or E24 type petrol
biofuels (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
vehicles 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 vehicle
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 unleaded
fuel is compulsory.
The fi ller neck is narrower, admitting un-
leaded 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


Take care when working under
the bonnet, as certain areas of
the engine may be extremely hot
(risk of burns) and the cooling
fan could start at any time (even
with the ignition off).


The check is carried out either
when the ignition is switched
on using the oil level indicator
in the instrument panel, or us-
ing the dipstick.
It will only be correct if the vehicle is on
level ground and the engine has been
off for more than 30 minutes.
It is normal to top up the oil level be-
tween two services (or oil changes).
CITROËN recommends that you check
the level, and top up if necessary, every
3 000 miles (5 000 kms).
After topping up the oil, the check when
switching on the ignition with the oil
level indicator in the instrument panel
is not valid during the 30 minutes after
topping up.


















Oil level


Engine oil change
Refer to the maintenance and warranty
guide for details of 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.











Brake fluid level


Changing the fl uid
Refer to the maintenance and warranty
guide for details of the interval for this
operation.

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












Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. With the engine cold, un-
screw the cap 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.
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.

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

Check all of these levels regularly, in
line with the maintenance and warranty
guide. Top them up if necessary, unless
otherwise indicated.
If a level drops signifi cantly, have the
corresponding system checked by a
CITROËN dealer or a qualifi ed work-
shop.

Oil specifi cation
The oil must be the correct grade for
your engine and conform to the manu-
facturer's recommendations.








The cooling fan may start after
switching off the engine: take
care with articles and clothing
that might become caught by the
fan blades.
The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

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 corro-
sive.
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)
The additive reservoir low level is indi-
cated 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 lter additive level is too low.


Screenwash / headlamp wash
fluid 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.
In wintry conditions, the use of a fl uid
with an ethyl alcohol or methanol base
is recommended.
To check the level or top up
the fl uid on vehicle fi tted with
headlamp washers, immobilise
the vehicle and switch of the
engine.



Open the bonnet and secure it with
the stay.


Open the screenwash reservoir fi ll-
er cap.


Take and pinch the level gauge to
block its breather.


Remove the gauge completely from
the reservoir to read the level in the
transparent section.


Top up if necessary.


Refi t the fi ller cap to the reservoir
and close the bonnet.

Particle emission filter (Diesel)

The start of saturation of the particle
emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an
audible 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 specifi -
cation. The involvement of a CITROËN
dealer or a qualifi ed workshop is essen-
tial when replacing or disconnecting the
battery. On a new vehicle, the fi rst op-
erations of regeneration of the
particle emissions fi lter may be
accompanied by the smell of
"burning", which is perfectly nor-
mal.
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. 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.
Unless otherwise indicated, check
these components in accordance with
the maintenance and warranty guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed work-
shop.





















Air filter and passenger compartment filter


Refer to the maintenance and
warranty guide 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 driving), replace
them twice as often if necessary
.
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.















Oil filter

Replace the oil fi lter each time
the engine oil is changed.
Refer to the maintenance and
warranty guide for details of
the replacement interval for
this component.













12 V 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 "12 V battery" section for
details of the precautions to be taken
before disconnecting the battery and
following its reconnection.

Automatic gearbox
The gearbox does not require
any maintenance (no oil change).
Refer to the maintenance and
warranty guide for details of
the level checking interval for
this component.
















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 work-
shop.





















Manual parking brake

















Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
those in the braking system,
CITROËN selects and offers
very specifi c products.
After washing the vehicle, damp-
ness, or in wintry conditions, ice
can form on the brake discs and
pads: braking effi ciency may be
reduced. Make light brake ap-
plications to dry and defrost the
brakes.
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 quali-
fi ed workshop.
















Brake pads

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 circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn.


Brake disc wear

For information on checking
brake disc wear, contact a
CITROËN dealer or a quali-
fi ed workshop.
For more information, refer to the "Electric
parking brake - Operating faults" section.








Manual gearbox

The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the maintenance and
warranty guide for the details
of the level checking interval
for this component.







Electronic gearbox

The gearbox does not require
any maintenance (no oil change).
