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.

control of the various front and rear
lamps providing the vehicle’s ligh-
ting.
Main lighting
The various front and rear lamps of
the vehicle are designed to adapt
the driver’s visibility progressively in
relation to the climatic conditions:
- sidelamps, to be seen,
- dipped beam headlamps to see without dazzling other drivers,
- main beam headlamps to see clearly when the road is clear.
Additional lighting
O t h e r l a m p s a r e fi t t e d t o f u l fi l t h e
requirements of particular driving

Model with rear foglamp only Model with front and rear
foglamps
In good or rainy weather, both day and night, the front foglamps and the rear
foglamp are prohibited. In these situations, the power of their beams may
dazzle other drivers. They should only be used in fog or snow.
In these weather conditions, it is your responsibility to swit ch on the foglamps
and dipped beam headlamps manually as the brightness sensor may d etect
s u f fi c i e n t l i g h t .
Do not forget to switch off the front foglamps and the re ar foglamp when they
are no longer necessary. Switching off of the lamps when
the ignition is switched off
On switching off the ignition, all of the
lamps turn off immediately, except
for dipped beam if guide-me-home
lighting is activated.
Switching on the lamps after
the ignition is switched off
To reactivate the lighting control, ro-
tate ring
A to the "0" position - lamps
off, then to the desired position.
On opening the driver’s door a
temporary audible signal warns the
driver that the lighting is on.
The lamps, with the exception of
the sidelamps, switch off automati-
cally after a maximum duration of
thirty minutes to prevent dischar-
ging of the battery.
In some climatic conditions (e.g.
l o w t e m p e r a t u r e o r h u m i d i t y ) , t h e
presence of misting on the internal
surface of the glass of the head-
lamps and rear lamps is normal;
it disappears after the lamps have
been on for a few minutes.

system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured

S e n s o r ( s ) n o t d e t e c t e d o r f a u l t y
The service warning
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
markings" section) to ensure that
the optimum dynamic performance
of the vehicle is maintained and
prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.

programme (ESP)
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. T h i s i s i n d i c a t e d b y fl a s h i n g
of this warning lamp on the
instrument panel. Deactivation
I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
Press the "ESP OFF" button, lo-
cated in the centre of the dash-
board. Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).
Press the "ESP OFF" button again
to reactivate them manually.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated. Operating fault
If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.

ceptional safety in normal driving,
but this should not encourage the
d r i v e r t o t a k e e x t r a r i s k s o r d r i v e a t
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.
The anti-skid regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme acts
on the brake of one or more wheels
and on the engine to keep the vehicle
on the trajectory required by the driver,
within the limits of the laws of physics.
