A few definitions… 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)
Distance travelled
(miles or km) Average speed
(mph or km/h)
This indicates the distance which
can still be travelled with the fuel re-
maining in the tank based on the av-
erage fuel consumption over the last
few miles (kilometres) travelled. This fi gure may increase follow-
ing a change in the style of driving
or terrain, 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. This function is only displayed
above 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 indicates the distance travelled
since the last trip computer zero reset. This is the average speed calculat-
ed since the last trip computer zero
reset (ignition on).

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 (exterior temperature, sun-
shine). This eliminates any need for
you to change your settings other
than the temperature value dis-
played.

 Please do not block the sunshine
sensor A .
If you select the automatic mode (by
pressing the "AUTO" control) and
leave all of the vents open, optimum
comfort will be maintained and humid-
ity and condensation will be removed
regardless of the exterior climatic con-
ditions.
The temperature in the passenger
compartment can only be lower than
the exterior temperature if the air
conditioning is on.
VENTILATION, HEATING AND AIR CONDITIONING RECOMMENDATIONS
In order to be effective, the air condi-
tioning must be used with the windows
closed. If the vehicle has been parked
in the sun for a long period and the in-
terior temperature is very high, venti-
late 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 the engine
power during its operation. As a result,
the fuel consumption of the vehicle in-
creases.
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 condi-
tioning permits the recovery of engine
power and therefore increases 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 has to be changed in ac-
cordance with the vehicle mainte-
nance schedule (see: "Maintenance
and Warranty Guide").

It controls the temperature, air fl ow
and intake and distributes the ven-
tilation 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 mirrors. The in-
dicator lamp comes on.
Demisting is switched off automatically
to prevent an excessive consumption
of current and in relation to the exterior
temperature.
It may be stopped by pressing con-
trol 7 again or when the engine is
switched off.
7. Rear demisting - de-icing
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 op-
timum level gradually to pre-
vent an excessive distribution
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 exterior
mirrors demisting when you consider
this necessary as low current con-
sumption reduces fuel consumption.

 Press control 8 sever-
al times to set the air
intake mode, the indi-
cator lamp comes on.

It must be cancelled as soon as
possible to permit renewal of the
air in the passenger compartment
and demisting.

C O M F O R T When starting with the engine
cold, the 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 - de-icing
In certain cases, the

"AUTO" mode may not be
suffi cient to demist or de-
ice the windows (humidity,
several passengers, ice).

 Press control 9 to clear the win-
dows quickly. The indicator light
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 - de-icing
Switch off the rear screen and exterior
mirrors demisting when you consider
this necessary as low current con-
sumption 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 light comes on.
Demisting is switched off automatically
to avoid excessive consumption of
current and depending on the exterior
temperature.
It may be stopped by pressing con-
trol 8 again or when the engine is
switched off.
In this latter case, the demisting
resumes if the engine is switched on
again within one minute.

Precautions in use:
The alarm volumetric movement
sensor may be disturbed by the air-
fl ow from the programmable heating
while in operation.
To avoid a false alarm while using the
programmable heating, it is recom-
mended to deactivate the volumetric
protection. Always switch off the program-
mable heating while refuelling in
order to avoid the risk of fi re or
explosion.
To avoid any risk of intoxication or
asphyxiation, the additional heat-
ing must not be used, even for
short periods, in an enclosed area
such as a garage or workshop not
equipped with a system for the ex-
traction of exhaust gases.
Do not park the vehicle over in-
fl ammable materials (e.g. dry
grass, dead leaves or paper) as
this could present a fi re risk.
The programmable heating sys-
tem is supplied by the vehicle’s
fuel tank. Before use, ensure that
the remaining fuel level is suf-
fi cient. If you are on the reserve
fuel level , we strongly advise you
not to use the programmable
heating system.

FUEL TANK

Capacity of the tank: approxi-
mately 71 litres.
Low fuel level
When the minimum level
in the tank is reached,
this warning lamp comes
on in the instrument
panel, accompanied by an audible
warning and a message on the mul-
tifunction screen.

You have enough fuel left to drive
approximately 30 miles (approx.
50 km).
 Press at the top left corner, then
pull open from the left.
 turn the key a quarter turn to lock
and unlock the fi ller cap,

 when refuelling, place the cap on
hook A ,

 fi ll the tank, but do not persist
after the third cut-off ; this could
cause your vehicle to malfunc-
tion.

While you are refuelling, the en-
gine must be stopped and the ig-
nition switched off.

For a petrol engine with a cata-
lytic converter, unleaded fuel is
compulsory.

Fuel quality
A label inside the fi ller fl ap tells you
which type of fuel to use.
The petrol engines are designed to
run on RON 95.
However, for better performance
(petrol engine), we recommend
RON 98.
In winter conditions, starting from
cold may sometimes seem diffi cult.
During periods of very cold weather
we recommend the use of 95 or 98
unleaded petrol in preference to
E85 so as to ensure optimum start-
ing performance.
BioFlex engine
A Biofl ex vehicle is one that has
been designed to operate equally
on unleaded petrol (95 or 98 RON)
or on bioethanol (in Europe this is a
mixture of 85 % ethanol and 15 %
unleaded petrol, known as E85).
As a result, no matter how much fuel
remains in the tank, and whatever
this fuel may be (unleaded petrol,
E85 or a mixture of the two) you can
refuel at any time with unleaded pe-
trol (95 or 98 RON) or with bioetha-
nol (E85).
There is no problem in running this
vehicle on only unleaded petrol.

If you should put in fuel that is
not suitable for your vehicle’s
engine type, it is imperative to
have the tank drained before
you start the engine again.
