ECO-DRIVING

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 effi ciency indicator invites you to
change up; it is displayed in the instru-
ment 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
traffi 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 win-
dows 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 defrosting
controls, if not automatic.
Switch off the heated seat as soon as
possible.

Switch off the headlamps and front fo-
glamps 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.
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO
2 emissions.

25

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 (en-
gine oil, oil fi lter, air fi lter...) and observe
the schedule of operations recommend-
ed 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.

A few definitions
(trip computer)

Range
(miles or km)
Current fuel
consumption
(mpg or l/100 km or km/l)

Average fuel
consumption
(mpg or l/100 km or km/l)

Average speed
(mph or km/h)
Distance travelled
(miles or km)
This indicates the distance which
can still be travelled with the fuel re-
maining in the tank in relation to the
average fuel consumption over the
last few miles (kilometres) travelled.
This value may vary following a
change in the style of driving or
the relief, resulting in a signifi cant
change in the current fuel con-
sumption.
When the range falls below 20 miles
(30 km), dashes are displayed. After
fi lling with at least 5 litres of fuel,
the range is recalculated and is dis-
played when it exceeds 60 miles
(100 km).
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer
or a qualifi ed workshop. This function is only displayed from
20 mph (30 km/h). This is the average fuel consump-
tion during the last few seconds.
This is the average fuel consump-
tion since the last trip computer zero
reset.
This is the average speed calculated
since the last trip computer zero reset
(ignition on). This indicates the distance travelled
since the last trip computer zero reset.








Stop & Start time
counter
(minutes / seconds or hours /
minutes)
If your vehicle is fi tted with Stop &
Start, a time counter calculates the
time spent in STOP mode during a
journey.
It resets to zero every time the igni-
tion is switched on with the key.

COMFORT

Air conditioning

We recommend use of the automatic
regulation of the air conditioning.
It permits automatic and optimised
control of all of the following func-
tions: air fl ow, temperature in the
passenger compartment and air
distribution, by means of various
sensors (ambient temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.


)
Take care not to cover the sun-
shine sensor A
.
If you select the automatic mode
(by pressing the "AUTO" control)
and leave all of the vents open, opti-
mum comfort will be maintained and
humidity and condensation will be
removed regardless of the exterior
climatic conditions.
The temperature in the passenger
compartment can only be lower than
the ambient temperature if the air
conditioning is on.
HEATING, VENTILATION
AND AIR CONDITIONING
RECOMMENDATIONS In order to be effective, the air con-
ditioning must be used with the win-
dows closed. If the vehicle has been
parked in the sun for a long period
and the interior temperature is very
high, fi rst ventilate the passenger
compartment with the windows
open for a few minutes, then close
the windows.
To keep the air conditioning system
in good working order it is essential
that it is operated at least once a
month.
The air conditioning uses engine pow-
er during its operation. As a result,
the fuel consumption of the vehicle
increases.
In certain cases of particularly ardu-
ous use (e.g. towing the maximum
load on a steep gradient in high tem-
peratures), switching off the air con-
ditioning saves engine power and
improves the towing capacity.


Air inlet

Check that the exterior grille for the
air inlet, at the bottom of the wind-
screen, is clean and free of dead
leaves, snow, etc.
When washing the vehicle using a
high pressure nozzle, avoid spray-
ing at the air inlet.


Air circulation

Maximum comfort is obtained by
means of a good distribution of air in
the passenger compartment, both in
the front and in the rear.
To obtain a uniform distribution of
air, take care not to block the ex-
terior air intake grille located at the
base of the windscreen, the vents,
the air outlets under the front seats
and the air extractor located behind
the fl aps in the boot.
The front and rear vents are fi tted
with thumbwheels to adjust the air
fl ow and direction. We recommend
that you leave all of the vents open.


Dust filter / Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter must be changed in line
with the vehicle's servicing schedule
(see the vehicle's servicing booklet).

COMFORT
The "Demisting" mode controls the
temperature, air fl ow and intake
and distributes the ventilation to the
windscreen and front side windows.
Resuming manual control exits from
"Demisting" mode. It must be can-
celled to permit renewal of the air
in the passenger compartment and
demisting.
Once the screen is clear, press-
ing control 1
returns the system to
"AUTO"
mode.


)
Press control 7
, with
the engine running,
to demist the rear
screen and the door
mirrors. The indica-
tor lamp comes on.
7. Rear demisting - defrosting
The heated rear screen operates in-
dependently of the air conditioning
system.
8. Intake of exterior air /
Recirculation of interior air
This function enables you to isolate
the passenger compartment from
exterior fumes and odours.


- When starting with the engine
cold, the fl ow will reach its
optimum level gradually to
prevent an excessive distribu-
tion of cold air.

- When entering the vehicle af-
ter it has been parked for a
fairly long period, if the inte-
rior temperature is very differ-
ent from your comfort setting
there is no need to change
the temperature displayed
in order to quickly reach the
level of comfort required. The
system automatically uses its
maximum performance to cor-
rect the difference in tempera-
ture as quickly as possible.

- The water resulting from the
air conditioning condensation
is discharged via an open-
ing provided for this purpose;
therefore, a puddle of water
may form underneath the ve-
hicle when stationary.

- In all seasons, if the weather
is cool, the air conditioning
is useful as it removes the
humidity from the air and the
condensation. Avoid driving
for prolonged periods with the
air conditioning switched off.

However, demisting resumes when
the engine is switched on again.
Switch off the rear screen and door
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.
)
Press control 8
to set
the air intake mode,
the indicator lamp
comes on.






With Stop & Start, when demist-
ing has been activated, the STOP
mode is not available.

Demisting is switched off automatically
to prevent an excessive consumption
of current and in relation to the ambient
temperature.
It may be stopped by pressing con-
trol 7
again or when the engine is
switched off.
It must be cancelled as soon as
possible to permit renewal of the
air in the passenger compartment
and demisting.



You can store the air condition-
ing settings. Refer to the "Storing
driving positions" section.

COMFORT
When starting with the engine
cold, air fl ow will reach its opti-
mum level gradually to prevent an
excessive distribution of cold air.
When entering the vehicle after it
has been parked for a fairly long
period, if the interior temperature
is very different from your comfort
setting there is no need to change
the temperature displayed in or-
der to quickly reach the level of
comfort required. The system
automatically uses its maximum
performance to correct the differ-
ence in temperature as quickly as
possible.
The water resulting from the air
conditioning condensation is dis-
charged via an opening provided
for this purpose; therefore, a pud-
dle of water may form underneath
the vehicle when stationary.
In all seasons, if the weather is
cool, the air conditioning is use-
ful as it removes the humidity
from the air and the condensa-
tion. Avoid driving for prolonged
periods with the air conditioning
switched off.
9. Front demisting - defrosting
In certain cases, the
"AUTO"
mode may not
be suffi cient to demist
or defrost the windows
(humidity, several pas-
sengers, ice).


)
Press control 9
to clear the win-
dows quickly. The indicator lamp
comes on.
This system controls the temperature,
air fl ow and intake and distributes the
ventilation to the windscreen and front
side windows.
Resuming manual control exits from
the "Demisting" mode. It must be
cancelled as soon as possible to
permit renewal of the air in the pas-
senger compartment and demisting.
Pressing one of the controls 1a

and 1b
returns the system to the
"AUTO"
mode.
8. Rear demisting - defrosting

Switch off the rear screen and exterior
mirrors demisting when you consider
this necessary as low current consump-
tion reduces fuel consumption.

The heated rear screen
operates independently
of the air conditioning
system.


)
Press control 8
, with the en-
gine running, to demist the rear
screen and the mirrors. The indi-
cator lamp comes on.
Demisting is switched off automatical-
ly to avoid excessive consumption of
current and depending on the exterior
temperature.
It may be stopped by pressing
control 8
again or when the engine
is switched off.
In this latter case, the demisting re-
sumes if the engine is switched on
again within one minute.






With Stop & Start, when demisting
has been activated, the STOP mode
is not available.
