Quality of the fuel used for
petrol engines

The petrol engines are per fectly compatible
with E10 or E24 type petrol biofuels (containing10 % or 24 % ethanol), conforming to Europeanstandards EN 228 and EN 15376.
E85 type fuels (containing up to 85 % ethanol)
are reser ved exclusively for vehicles marketed for the use of this type of fuel (BioFlex
vehicles). The quality of the ethanol mustcomply with European standard EN 15293.
For Brazil only, special vehicles are marketed
to run on fuels containing up to 100 % ethanol(E10 0 type). If
you are filling your tank to the top, do notpersist after the third cut- off; this could
cause your vehicle to malfunction. The petrol or Diesel engine of your vehicle isfitted with a catalytic conver ter, a device which
helps to reduce the level of harmful emissions
in the exhaust gases.
For petrol engines, the use of unleaded fuel
is compulsory. The filler neck is narrower, admitting unleaded
petrol nozzles only.



Fuel supply cut-off

Your vehicle is equipped with a safety device
which cuts off the fuel supply in the event of acollision.
If you have put in the wrong fuel for your vehicle, you must have havethe tank drained and refilled withthe correct fuel before you star t the engine.
)Introduce the nozzle so as to push in themetal non-return flap B.
)Make sure that the nozzle is pushed in as
far as possible before star ting to refuel(risk of blowback).)Maintain this position while refuelling.)Push the fuel flap to close it.

Access
Quality of the fuel used for
Diesel engines

The Diesel engines are per fectly compatible
with biofuels which conform to current andfuture European standards (Diesel fuel which complies 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 ser vicing conditions. Contact a CITROËN dealer or a qualified
workshop.
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).


















Misfuel prevention (Diesel) * 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.
When a petrol filler nozzle is introduced into the
fuel filler neck of
your Diesel vehicle, it comesinto contact with the flap. The system remains closed and prevents filling. Do not persist but introduce a Diesel typefiller nozzle.
Operation
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 themisfuel prevention device and pour slowly.

151Fittings
230 V/50 Hz power socket

A 230 V/50 Hz socket (maximum power: 120 W)
is fitted to the centre console.
To use the socket:)lift the front armrest cover for access to itscompartment,)check that the warning lamp is on green, )connect your multimedia or other electricaldevice (telephone charger, laptop computer,CD-DVD player, baby food warmer...).
This socket works with the engine running, as
well as in ST
OP mode on Stop & Star t.
In the event o
f a fault with the socket, the green
warning lamp flashes.
Have it checked by a CITROËN dealer or a qualified workshop.
Connect only one device at a time to the socket (no extension or multi-wayconnector).Connect only devices with class IIinsulation (shown on the device). As a safety measure, when electricalconsumption is high and whenrequired by the vehicle's electrical system (particular weather conditions, electrical overload...), the current
supply to the socket will be cut off;the green warning lamp goes off.







12 V accessory
socket
) To connect a 12 V accessory (max power: 120 W), lift the cover and connect a suitable adaptor.

179Safety
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.

Activation

It is triggered by the speed at which the brake pedal is pressed.
The effect of this is a reduction in theresistance of the pedal and an increase in
braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.

















Trajectory control systems (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.The electronic stability control 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.

Activation
These systems are activated automaticallyeach time the vehicle is started.
They come into operation in the event of a gripor trajectory problem.
This is indicated b
y flashing of this
warning lamp in the instrument panel.

Intelligent traction control
s
ystem ("Snow motion")
Your vehicle has a system to help driving on snow: intelligent traction control.
This system detects situations of difficult surface adhesion that could make it difficult to
move off or make progress on deep fresh snowor compacted snow.
In these situations, the intelligent tractioncontrol limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly recommended on surfaces offering low levels of adhesion.

Safety

When the ignition is switched on, with the
engine running or when the vehicle is moving at less than 12 mph (20 km/h), the corresponding warning lamps 3, 4 and 5
come on in red for approximately 30 seconds, if the seat belt is not
fastened.
When the vehicle is moving at more than 12 mph (20 km/h), the corresponding warning lamps 3,4and 5come on in red, accompanied by anaudible signal and a message in the screen, if a rear passenger has unfastened their seat belt. From approximatel
y 12 mph (20 km/h),
this warning lamp flashes for two minutes
accompanied by an audible signal of increasingvolume. Once these two minutes have elapsed,
this warning lamp remains on until the one or more rear passengers fasten their seat belt.

Electric parking brake
The electric parking brake combines
2 operational modes:- Automatic Application/ReleaseApplication is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),-Manual Application/ReleaseThe parking brake can be applied/releasedmanually by pulling control lever A.

Do not place any object (packet of cigarettes, telephone...) between thegear lever and the electric parkingbrake control lever.


It is recommended that you do notapply the parking brake in very coldconditions (ice) and during towing (breakdown, caravan...). Deactivate the automatic functions and release the parking brake manually.
If this warnin
g lamp comes on in
the instrument panel, the automatic
m
ode is deactivated.
Programming the mode

Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release whenyou press the accelerator can be deactivated.

Activation/deactivation is done
using the vehicle configurationmenu; refer to the section covering
the configuration of your vehicle'ssystems.

The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible si
gnal and a message is
displayed if the brake is not applied.
