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 diluted, domestic fuel...) is
strictly prohibited (risk of damage to
the engine and fuel system). Special features of BioFlex
engines
A BioFlex vehicle has been designed
to run on unleaded petrol (RON 95
or RON 98) or ethanol (this is a mix-
ture containing 85 % ethanol and
15 % unleaded petrol, called E85).
So, regardless of the quantity of fuel
remaining in your tank and irrespec-
tive of its type (RON 95/RON 98,
E85 or a mixture of the two), you
can fi ll your tank at any time with un-
leaded petrol (RON 95 or RON 98)
or ethanol (E85).
There is no problem driving on un-
leaded petrol only with this vehicle.
In winter conditions, starting the
engine from cold may sometimes
prove diffi cult. During these very
cold periods you are advised to
use unleaded petrol rather than
E85 to ensure optimum starting
conditions.

RUNNING OUT OF FUEL (DIESEL)
HDi 135 and 140 engine
Detach the protection cover to gain
access to the priming pump. HDi 90 and 110 engine
Detach the protection cover to gain
access to the priming pump. Priming the fuel system
In the event of running out of fuel:

 after fi lling (minimum 5 litres),
squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,

 then operate the starter, gently
pressing the accelerator until the
engine starts.
If the engine fails to start at the fi rst
attempt, wait 15 seconds before
trying again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.
HDi engines are of a highly
technical nature.
All maintenance and re-
pairs require specialist knowledge
which only your CITROËN dealer
can assure.
