Use the cruise control only where the
driving conditions allow running at a
constant speed for a while and at an
adequate safe distance.
Do not activate the cruise control in urban
areas, in heavy traffic, on winding or steep
roads, on slippery or flooded roads, or in
conditions of poor visibility (heavy rain,
fog, falling snow etc.).
In some circumstances, it may not
be possible to maintain or reach the
programmed speed: towing, vehicle
heavily loaded, steep climb, etc.
The use of mats not approved by the
manufacturer may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the pedals:
-
e
nsure that the mat is positioned
c o r r e c t l y,
-

n
ever place one mat on top of another.Lane departure warning
system
System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motor ways
and main roads.The lane departure warning system
cannot, in any circumstances replace the
need for vigilance on the part of the driver.
It is necessary to obser ve the driving
regulations and take a break every two
hours.
Activation
F When switching on the ignition or with the engine running, press this button to activate
the system; the indicator lamp comes on.
Deactivation
F Press this button again, the indicator lamp goes off.
The status of the system remains in memory
when the ignition is switched off.

seat cushion:
-

o
n the right-hand side, if the marking on the
road has been crossed on the right,
-

o
n the left-hand side, if the marking on the
road has been crossed on the left.
No warning is given while the direction indicator
is active and for approximately 20 seconds
after the direction indicator is switched off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
Malfunction
In the event of a malfunction, the
Ser vice warning lamp comes on,
accompanied by an audible signal
and a message in the screen.

Fuel
Tank capacity: approximately 60 litres.
Low fuel level
When the low fuel level is reached
in the tank, this warning lamp
comes on in the instrument panel,
accompanied by an audible warning
and the display of an alert message.
When it first comes on, about
6 litres of fuel is left in the tank.
Until sufficient fuel has been added, every time
the ignition is switched on, this warning lamp
appears, accompanied by an audible signal
and an alert message. When driving, this
audible signal and alert message are repeated
with increasing frequency, as the level drops
towards 0 .
You must refuel as soon as possible to avoid
running out of fuel.
If you run out of fuel (Diesel), refer to the
corresponding section.
Refuelling
Additions of fuel must be of at least 5 litres, in
order to be registered by the fuel gauge. With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key, or the START/
STOP button if your vehicle has Keyless
Entry and Starting.
Opening the filler cap may create a noise
caused by an inrush of air. This vacuum is
entirely normal, resulting from the sealing of the
fuel system.

opening of the fuel flap is heard.
This control remains active for a few minutes after switching off the ignition. If necessary,

If you are filling your tank to the top, do not
persist after the third cut- off; this could
cause your vehicle to malfunction.
Your vehicle is fitted with a catalytic converter,
which helps to reduce the level of harmful
emissions in the exhaust gases.
For petrol engines, you must use unleaded
fuel.
The filler neck is narrower, allowing only
unleaded petrol nozzles to be introduced.

If you have put in the wrong fuel for
your vehicle, you must have the fuel
tank drained and filled with the correct
fuel before star ting the engine.
Fuel cut-off
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
Misfuel prevention
(Diesel)
(Depending on the country of sale.)
Mechanical device which prevents filling the
tank of a Diesel vehicle with petrol. It avoids
the risk of engine damage that can result from
filling with the wrong fuel.
Located in the filler neck, the misfuel
prevention device appears when the filler cap
is removed.
Operation
When a petrol filler nozzle is introduced into
your Diesel tank, it comes into contact with the
flap. The system remains closed and prevents
filling.
Do not persist but introduce a Diesel type
filler nozzle.It remains possible to use a fuel can to fill
the tank.
In order to ensure a good flow of fuel,
do not place the nozzle of the fuel can in
direct contact with the flap of the misfuel
prevention device and pour slowly. Travelling abroad
As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may make
refuelling impossible.
Not all Diesel vehicles are fitted with
misfuel protection, so before travelling
abroad, we recommend that you check
with the dealer network whether your
vehicle is suitable for the fuel pumps in the
country in which you intend to travel.

Compatibility of fuels
Fuel used for petrol engines
The petrol engines are compatible with biofuels
that conform to current and future European
standards and which can be obtained from
filling stations:Petrol that meets standard EN228,
mixed with a biofuel that meets
standard EN15376.
The only petrol additives authorised for
use are those that meet the B715001
standard.
Fuel used for Diesel engines
The Diesel engines are compatible with
biofuels that conform to current and future
European standards and which can be
obtained from filling stations. Diesel fuel that meets standard
EN590 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 7% Fatty Acid Methyl
Ester), For more information, contact the dealer
network or a qualified workshop.Diesel fuel that meets standard
EN16734 mixed with a biofuel that
meets standard EN14214 (possibly
containing 0 to 10% Fatty Acid
Methyl Ester),
Paraffinic Diesel fuel that meets
standard EN15940 mixed with
a biofuel that meets standard
EN14214 (possibly containing 0 to
7% Fatty Acid Methyl Ester).
The use of B20 or B30 fuel meeting
standard EN16709 is possible in
your Diesel engine. However, this
use, even occasional, requires strict
application of the special ser vicing
conditions referred to as "Arduous
conditions".
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). The only Diesel additives authorised for
use are those that meet the B715000
standard.
Diesel at low temperature
At temperatures below 0°C (+32°F), the
formation of paraffins in summer-type Diesel
fuels could entail an abnormal operation
of the fuel supply circuit. To avoid this, we
recommend using winter-type Diesel fuel and
keeping the fuel tank more than 50% full.
If, despite this, at temperatures below -15°C
(+5°F) the engine has problems starting,
just leave the vehicle in a garage or heated
workshop for a little while.
Travelling abroad
Certain fuels could damage the engine of your
vehicle.
In certain countries, the use of a particular
fuel may be required (specific octane rating,
specific sales name…) to ensure correct
operation of the engine.
For any additional information, contact the
dealer network.

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy saving mode
System that manages the duration of use of
certain functions to conser ve a sufficient level
of charge in the battery.
After the engine has stopped, you can
still use functions such as the audio
equipment, windscreen wipers, dipped
beam headlamps,
courtesy lamps, etc. for a
maximum combined period of thirty minutes.
This period may be greatly reduced if the
battery is not fully charged.
Switching to this mode
Once this period has elapsed, a message
appears in the screen indicating that the
vehicle has switched to the energy saving
mode and the active functions are put on
st a n d by.If the telephone was operated via
the touch screen at that moment, the
