Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows for a few moments, then close
them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.

cordance with the vehicle servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
F o r o p t i m u m o p e r a t i n g e f fi c i e n c y ,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
a n d t h u m b w h e e l s t o a d j u s t t h e a i r fl o w
and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunshine sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

Refuelling
A l a b e l o n t h e i n s i d e o f t h e fl a p r e -
minds you of the type of fuel to be
used for your engine.
More than 5 litres of fuel must be
added in order to be registered by
the fuel gauge.
The key cannot be removed from
the lock until the cap is put back on
the tank.
Opening the cap may cause an in-
rush of air. This vacuum, which is
perfectly normal, is caused by the
sealing of the fuel system. P e t r o l v e h i c l e s : t h e fi l l e r n e c k h a s a

Capacity of the tank: approximately 60 litres.
Low fuel level When the minimum level
in the fuel tank is reached,
this warning lamp in the in-
strument panel comes on,
accompanied by an audible signal
and a message on the multifunction

have approximately 6 litres of fuel
remaining in the tank.
You must refuel to avoid running out
of fuel.
If you run out of fuel (Diesel), refer to
the "Checks" section also.
Fuel cut-off switch
Your vehicle is equipped with a safety
device which cuts off the fuel supply in
the event of a collision. T o fi l l t h e t a n k s a f e l y :
you

switch off the en-
gine,

then turn it to the left,

after the 3rd cut-off of the nozzle ;
this could cause malfunctions.
When the tank is full:
put the cap back in place,
turn the key to the right, then re-
move it from the cap,

Quality of the fuel used for
petrol engines
The petrol engines are perfectly
compatible with E10 type petrol
biofuels (containing 10 % ethanol),
conforming to European standards
EN 228 and EN 15376.
E85 type fuels (containing up to 85 %
ethanol) are reserved exclusively for
vehicles marketed for the use of this
type of fuel (BioFlex vehicles). The
quality of the ethanol must comply
with European standard EN 15293.
F o r B r a z i l o n l y , s p e c i a l v e h i c l e s a r e
marketed to run on fuels containing
up to 100 % ethanol (E100 type). Quality of the fuel used for
Diesel engines
The Diesel engines are perfectly
compatible with biofuels which con-
form to current and future European
standards (Diesel fuel which com-
plies with standard EN 590 mixed
with a biofuel which complies with
standard EN 14214) available at the
pumps (containing up to 7 % Fatty
Acid Methyl Ester).
The B30 biofuel can be used in cer-
tain Diesel engines; however, this
use is subject to strict application
of the special servicing conditions.
Consult a CITROËN dealer.
The use of any other type of
(bio)fuel (vegetable or animal oils,
pure or diluted, domestic fuel...) is
strictly prohibited (risk of damage to
the engine and fuel system). Special features of BioFlex
engines
A BioFlex vehicle has been designed
to run on unleaded petrol (RON 95
or RON 98) or ethanol (this is a mix-
ture containing 85 % ethanol and
15 % unleaded petrol, called E85).
So, regardless of the quantity of fuel
remaining in your tank and irrespec-
tive of its type (RON 95/RON 98,
E85 or a mixture of the two), you
c a n fi l l y o u r t a n k a t a n y t i m e w i t h u n -
leaded petrol (RON 95 or RON 98)
or ethanol (E85).
There is no problem driving on un-
leaded petrol only with this vehicle.
In winter conditions, starting the
engine from cold may sometimes
p r o v e d i f fi c u l t . D u r i n g t h e s e v e r y
cold periods you are advised to
use unleaded petrol rather than
E85 to ensure optimum starting
conditions.
