FAMILIARISATION
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.


Optimise the use of your
gearbox

With a manual gearbox, move off
gently, change up without waiting and
drive by changing up quite soon. If
your vehicle has the system, the gear
shift indicator invites you to change
up; it is displayed in the instrument
panel, follow its instructions.

With an automatic or electronic gear-
box, stay in Drive "D"
or Auto "A"
, ac-
cording to the type of gearbox, without
pressing the accelerator pedal heavily
or suddenly.



Drive smoothly


Maintain a safe distance between ve-
hicles, use engine braking rather than
the brake pedal, and press the accel-
erator progressively. These practices
contribute towards a reduction in fuel
consumption and CO
2 emissions and
also helps reduce the background traf-
fi c noise.

If your vehicle has cruise control, make
use of the system at speeds above
25 mph (40 km/h) when the traffi c is
fl owing well.



Control the use of your
electrical equipment

Before moving off, if the passenger
compartment is too warm, ventilate it
by opening the windows and air vents
before using the air conditioning.
Above 30 mph (50 km/h), close the
windows and leave the air vents
open.
Remember to make use of equipment
that can help keep the temperature
in the passenger compartment down
(sunroof and window blinds...).
Switch off the air conditioning, unless
it has automatic digital regulation, as
soon as the desired temperature is at-
tained.
Switch off the demisting and defrost-
ing controls, if not automatic.
Switch off the heated seat as soon as
possible.

ACCESS
FUEL TANK

Capacity of the tank: approxi-
mately 60 litres.



Low fuel level

When the low fuel level is
reached, this warning lamp
on the instrument panel
comes on, accompanied by
an audible warning and a message
on the multifunction screen.
When it fi rst comes on, about 7 litres

of fuel remain in the tank.
Until suffi cient fuel has been
added, this warning lamp appears
every time the ignition is switched
on, accompanied by an audible
warning and a message. Depending
on version, this audible warning
and message are repeated with
increasing frequency as the fuel
level drops towards " 0
".
Refuel as soon as possible to avoid
running out. A label on the inside of the fuel fi ller
fl ap reminds you of the type of fuel
to use, depending on your engine
type.
Additions of fuel must be of at least
5 litres to be registered by the fuel
gauge.

Refuelling


If you are fi lling your tank to
the top, do not persist after the
3rd cut-off; this could cause
malfunctions.






With Stop & Start, never refuel with
the system in STOP mode; you
must switch off the ignition with the
key. Opening the fi ller cap may result in
an inrush of air. This is entirely nor-
mal and results from the sealing of
the fuel system.


)
Press control switch A
, situated
on the switch panel on the left of
the dashboard, until the fuel fl ap
opens.
This control switch remains ac-
tive for a few minutes after
switching of the ignition. If nec-
essary, switch the ignition on
again to reactivate it.

)
Take care to select the pump
that delivers the correct type of
fuel for your vehicle.

)
Introduce the nozzle so as to push
in the metal non-return fl ap B.

)
Make sure that the nozzle is
pushed in as far as possible
before starting to refuel (risk of
blowback).

)
Maintain this position throughout
the refuelling operation.

)
Push the fuel fl ap to close it.

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.













Quality of the fuel used for
petrol engines











Quality of the fuel used for
Diesel engines

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).
