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 gen-
tly, 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
(sun roof 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.

Switch off the headlamps and front
foglamps when the level of light does
not require their use.
Avoid running the engine before mov-
ing off, particularly in winter; your ve-
hicle will warm up much faster while
driving.
As a passenger, if you avoid connect-
ing your multimedia devices (fi lm, mu-
sic, video game...), you will contribute
towards limiting the consumption of
electrical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.
Limit the causes of excess
consumption
Spread loads throughout the vehicle;
place the heaviest items in the bottom
of the boot, as close as possible to the
rear seats.
Limit the loads carried in the vehicle
and reduce wind resistance (roof bars,
roof rack, bicycle carrier, trailer...). Use
a roof box in preference.
Remove roof bars and roof racks after
use.
At the end of winter, remove snow
tyres and refi t your summer tyres.
Observe the recommendations
on maintenance
Check the tyre pressures regularly,
when cold, referring to the label in the
door aperture, driver's side.
Carry out this check in particular:
- before a long journey,
- at each change of season,
- after a long period out of use.
Don't forget the spare wheel and the
tyres on any trailer or caravan.
Have your vehicle serviced regularly
(engine oil, oil fi lter, air fi lter...) and ob-
serve the schedule of operations rec-
ommended by the manufacturer.
When refuelling, do not continue after
the 3 rd cut-off of the nozzle to avoid
any overfl ow.
At the wheel of your new vehicle,
it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see
the fuel consumption settle down to a
consistent average.

engine is started.
If it does not go off, contact a CITROËN
dealer or qualifi ed workshop without delay.
Low fuel level
fi xed,
accompanied
by and audible
signal and a
message. When it fi rst comes on there
remains approximately
6 litres
of fuel in the tank.
At this point, you begin to use
the fuel reserve. Refuel as soon as possible to avoid
running out of fuel.
Until suffi cient fuel is added, this warning
lamp will come on every time the ignition
is switched on, accompanied by an
audible signal and a message.
Depending on version, the audible
signal and message are repeated with
increasing frequency as the fuel level
drops towards "0"
.
Fuel tank capacity: approximately
60 litres
.
Never continue to drive until you run
out of fuel, as this could damage the
emission control and injection systems.
