Eco- driving
Eco-driving is a range of everyday practices
t hat allow the motorist to optimise their fuel
consumption and CO
2 emissions.
Optimise the use of your
gearbox
With a manual gearbox, move off gently
a nd change up without waiting. When
accelerating, change up early.
With an automatic gearbox, give preference
to automatic mode and avoid pressing the
accelerator pedal heavily or suddenly.
The gear efficiency indicator invites you to
engage the most suitable gear: as soon as the
indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted with an automatic gearbox,
this indicator appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles,
u se engine braking rather than the
brake pedal, and press the accelerator
progressively. These practices contribute
towards a
reduction in fuel consumption and
CO
2 emissions and also help reduce the
b
ackground traffic noise.
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 31
mph (50 km/h), close the windows
and leave the air vents open.
Consider using equipment that can help
keep the temperature in the passenger
compartment down (sunroof blind and window
blinds, etc.).
Switch off the air conditioning, unless it has
automatic regulation, as soon as the desired
temperature is attained. Switch off the headlamps and front foglamps
when the ambient light level does not require
their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a
passenger, if you avoid connecting your
multimedia devices (film, music, video game
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
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.
If your vehicle has cruise control, make use of
the system at speeds above 25

mph (40

km/h)
when the traffic is flowing well. Switch off the demisting and defrosting
controls when not required, if they are not
automatically controlled.
Switch off the heated seat as soon as
possible.

Heated seats
F Use the adjustment wheel to switch on and select the level of heating required:
0: Of f.
1: Low.
2: Medium.
3: High.
With the engine running, the front seats can be
heated separately. Do not use the function when the seat
is not occupied.
Reduce the intensity of the heating as
soon as possible.
When the seat and passenger
compartment have reached an
adequate temperature, you can stop
the function; reducing the consumption
of electrical current reduces fuel
consumption.
Prolonged use at the highest setting is
not recommended for those with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (illness,
taking medication, for example).
There is a risk of overheating the system if
material with insulating properties is used,
such as cushions or seat covers.
Do not use the function:
-
i
f wearing damp clothing,
-
i
f child seats are fitted.
To avoid breaking the heating element in
the seat:
-
d
o not place heavy objects on the seat,
-
d
o not kneel or stand on the seat,
-
d
o not place sharp objects on the seat,
-
d
o not spill liquids onto the seat.
To avoid the risk of short-circuit:
-
d
o not use liquid products for cleaning
the seat,
-
n
ever use the heating function when
the seat is damp.

Recommendations for ventilation and air conditioning
In order for these systems to be fully
effective, follow the operation and
maintenance guidelines below:
F
T
o ensure that the air is distributed
evenly, keep the external air intake
grilles at the base of the windscreen, the
nozzles, the vents, the air outlets and
the air extractor in the boot free from
obstructions.
F

D
o not cover the sunshine sensor,
located on the dashboard; this is used
for regulation of the automatic air
conditioning system.
F

O
perate the air conditioning system for
at least 5
to 10 minutes once or twice
a
month to keep it in per fect working
o r d e r.
F

E
nsure that the passenger compartment
filter is in good condition and have the
filter elements replaced regularly. We
recommend the use of a
combined
passenger compartment filter. Thanks to
its special active additive, it contributes
to the purification of the air breathed by
the occupants and the cleanliness of
the passenger compartment (reduction
of allergic symptoms, bad odours and
greasy deposits). If after an extended stop in sunshine,
the interior temperature is very high,
first air the passenger compartment for
a
few moments.
Put the air flow control at a
setting high
enough to quickly change the air in the
passenger compartment.
The condensation created by the air
conditioning results in a discharge of water
under the vehicle which is per fectly normal.
Stop & Star t
The heating and air conditioning systems
only work when the engine is running.
To maintain a
comfortable temperature
in the passenger compartment, you may
temporarily deactivate the Stop & Start
system.
For more information on Stop & Star t ,
refer to the corresponding section.
F

T

o 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.
F

I

f the system does not produce cold air,
switch it off and contact a

CITROËN
dealer or a

qualified 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.
To avoid the windows misting up and
deterioration in the quality of the air:
-

d

o not drive for too long with the
ventilation switched off.
-

d

o not keep air recirculation set for an
extended period.

minimum, you are
stopping ventilation.
Avoid driving for too long without
ventilation – risk of misting and
deterioration of air quality!

Central and side vents. Illumination of the button indicates the
presence of pulsed air in the specified
direction.
