Dynamic stability control
(ESP/ASR)
The ESP/ASR system is put
into service automatically

come on continuously, this indicates
the occurrence of a fault in the ESP/
ASR system or in the hill start as-
sistance. Engine autodiagnostics system
If this comes on, it indicates
the occurrence of a fault in
the engine management
system.
If it fl ashes, it indicates the occur-
rence of a fault in the emission con-
trol system.

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.
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
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.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

DIESEL FUEL
Refuelling
A label on the inside of the fuel fi ll-
er fl ap indicates the approved fuel
quality type.
To fi ll the tank safely:

 it is imperative that you switch
off the engine,

 open the fuel fi ller fl ap,

 insert the key in the fuel tank cap
then turn it to the left. Petrol engines are designed to run
on 95 RON fuel.
However, for better vehicle perform-
ance (petrol engines), we recom-
mend 98 RON.

For petrol engines with catalytic
converter, use of unleaded fuel is
obligatory
The fi ller neck has a narrower orifi ce
to admit only petrol fi ller nozzles.

UNLEADED PETROL
When you are fi lling your fuel
tank, do not persist after the
third cutoff; this could cause
your vehicle to malfunction.
FUEL TANK

Capacity of the tank: approxi-
mately 60 litres.
Low fuel level
When the minimum level in
the fuel tank is reached, this
warning lamp in the instru-
ment panel comes on, ac-
companied by an audible signal and a
message on the multifunction screen.

You have enough fuel left to drive
approximately 30 miles (50 km).
Fuel cut-off switch
Your vehicle is equipped with a safe-
ty device which cuts off the fuel sup-
ply in the event of a collision.

If you have put in fuel that is
wrong for your vehicle, it is es-
sential to have the tank drained
before you start the engine.
A label inside the fuel fi ller fl ap indi-
cates the fuels authorised:

In winter conditions, starting
from cold may seem diffi cult.
During periods of very cold
weather we recommend the use
of 95 or 98 unleaded petrol in
preference to B85 so as to ensure
optimum starting performance.
BioFlex
Your vehicle has been designed to
operate
equally on unleaded pet-
rol (95 or 98) or on bioethanol (in
Europe this is a mixture of 85 %
ethanol and 15 % unleaded petrol,
known as E85 ).
Other than the question of the two
authorised fuels, your vehicle is
used in the same way as a tradition-
al petrol vehicle.

Temporary manual operation
when in automatic mode
By pulling either of the paddles " + "
or " - ", you can exercise temporary
control over the changing of gears.
The request to change gear will be
taken into account. You will still be in
automatic mode. The warning lamp

A remains lit up in the instrument
panel.
This function enables you to antici-
pate certain situations such as the
approach of a bend or the need to
overtake another vehicle.

 Move the selector to position A .
The warning lamp A lights up in
the instrument panel to confi rm
the selection.
The gearbox then functions in auto-
matic mode, without any action on
your part.
It constantly selects the gear that is
best suited to the following condi-
tions:
- driving style,
- road profi le,
- optimum fuel consumption.
Operation in automatic mode
Cancellation of automatic
mode
The change from position A (driv-
ing in automatic mode) to position

M (driving in manual mode) or vice
versa can be made at any time. The
warning lamp A disappears in the in-
strument panel.

Protective cover
Removal

 Remove the protective cover by
unclipping fi rst point 1 , then 3
and 4 .

 Unclip point 2 pulling towards
you, then lift.
Refi tting

 Clip point 2 fi rst.

 Lower the cover, centring it.

 Clip points 1 and 4 , pushing ver-
tically and slightly rearwards.

 Clip point 3 , pushing vertically. Draining water from the fuel
filter
Bleed on a regular basis (at every
oil change).
To evacuate the water, slacken the
bleed screw or the water-in-diesel-
fuel sensor, which is located at the
base of the fi lter.
Persist until water ceases to fl ow
out.
Then retighten the bleed screw or
the water-in-diesel-fuel sensor.
