Quality of the fuel used for
petrol engines
The petrol engines are perfectly
compatible with E10 type petrol
biofuels (containing 10 % ethanol),
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
compatible with biofuels which con-
form to current and future European
standards (Diesel fuel which com-
plies with standard 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 cer-
tain Diesel engines; however, this
use is subject to strict application
of the special servicing conditions.
Consult a CITROËN dealer.
The use of any other type of (bio)fuel
(vegetable or animal oils, pure or di-
luted, domestic fuel...) is strictly pro-
hibited (risk of damage to the engine
and fuel system).
MISFUEL PREVENTION
Mechanical device which prevents
fi lling the tank of a Diesel vehicle
with petrol. It avoids the risk of
engine damage that can result from
fi lling with the wrong fuel.
Located in the fi ller neck, the misfuel
prevention device appears when the
fi ller cap is removed.
Operation
When a petrol fi ller nozzle is intro-
duced into the fuel fi ller neck of your
Diesel vehicle, it comes into contact
with the fl ap. The system remains
closed and prevents fi lling.

Do not persist but introduce a
Diesel type fi ller nozzle.
It is still possible to use a fuel can
to fi ll the reservoir.
In order to ensure a good fl ow of
fuel, do not place the nozzle of the
fuel can in direct contact with the fl ap
of the misfuel prevention device.

Fluid change
Refer to the Maintenance and

This fl uid must be changed regular-
ly. 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 meet the DOT4 standard.
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.
Check this level also between each
scheduled service and before long
journeys.
Take care when doing anything un-
der the bonnet, as some parts of the
engine can be extremely hot (risk of
burns). The brake fl uid level should
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
In order to maintain the reli-
ability of the engine and emis-
sion control system, the use
of additives in the engine oil is
prohibited. Power steering fluid or power

level via the oil fi ller
cap, using the type
of oil suited to your
engine.
