ACCESS
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, you must use
unleaded fuel.
The fi ller neck is narrower, allowing only
unleaded petrol nozzles to be intro-
duced.

If you have put in the wrong fuel
for your vehicle, you must have
the fuel tank drained and fi lled
with the correct fuel before start-
ing the engine.

Fuel cut-off

Your vehicle is equipped with a safe-
ty device which cuts off the fuel sup-
ply in the event of a collision.
The petrol engines are perfectly
compatible with E10 or E24 type pet-
rol biofuels (containing 10 % or 24 %
ethanol), conforming to European
standards EN 228 and EN 15376.
E85 type fuels (containing up to
85 % ethanol) are reserved exclu-
sively for vehicles marketed for the
use of this type of fuel (BioFlex ve-
hicles). The quality of the ethanol
must comply with European stan-
dard EN 15293.
For Brazil only, special vehicles are
marketed to run on fuels containing
up to 100 % ethanol (E100 type).

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.
Contact a CITROËN dealer or a
qualifi ed workshop.
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).
