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.

MONITORING

Warning and indicator lamps

Visual indicators which inform the driver of the occurrence of a malfunction (warn-
ing lamp) or of the operation of a system (operation or deactivation indicator
lamp).

When the ignition is switched on
Certain warning lamps come on for a few seconds when the ignition is switched on.
When the engine is started, these warning lamps should go off.
If they remain on, before moving off, refer to the information on the warning lamp in
question.

Associated warnings
The illumination, fi xed or fl ashing, of certain warning lamps may be accompanied
by an audible signal and a message in the multifunction screen or in the instru-
ment panel central screen associated with the satellite navigation system.

Warning lamps

When the engine is running or the vehicle is being driven, the illumination of one of the follow-
ing warning lamps indicates a malfunction which requires action on the part of the driver.
The warning comes on in the instrument panel or appears in the instrument panel central
screen associated with the satellite navigation system.
If your vehicle has a screen, a
warning lamp coming on is al-
ways accompanied by the dis-
play of an additional message,
to assist you in identifying the
problem.
If you encounter any problems,
do not hesitate to contact a
CITROËN dealer or a qualifi ed
workshop.

Action/Observations








STOP


fi xed, alone
or associated
with another
warning lamp,
accompanied by
an audible signal
and a message in

lamp is associated with
a serious braking system,
power steering, engine
lubrication or cooling system
malfunction or a punctured
tyre. Stop as soon as it is safe to do so as
there is a risk that the engine will cut out
while driving.
Park, switch off the ignition and contact a
CITROËN dealer or a qualifi ed workshop.






Maximum
coolant

fi xed red. The temperature of the
cooling system is too high. Stop as soon as it is safe to do so.
Wait until the engine has cooled down
before topping up the level, if necessary.
If the problem persists, contact a
CITROËN dealer or qualifi ed workshop.

RECOMMENDATIONS FOR VENTILATION AND AIR
CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air
intake grilles located at the base of the windscreen, the nozzles, the vents
and the air outlets, as well as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.

)
Ensure that the passenger compartment fi lter is in good condition and
have the fi lter elements replaced regularly (refer to the "Checks" sec-
tion).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).

)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a set-
ting high enough to quickly
change the air in the passenger
compartment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.



Stop & Start
The heating and air conditioning systems only work when the engine is run-
ning. To maintain a comfortable temperature in the passenger compartment,
you can temporarily deactivate the Stop & Start system (see "Driving").
