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 comes
into contact with the flap. The system remains
closed and prevents filling.

Do not persist but introduce a Diesel type
filler nozzle.




Operation

It remains possible to use a fuel can to
fill the tank; this must be done slowly.
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.

This equipment will become available during
the year.

*
According to country of sale.


Tr a v e l l i n g a b r o a d

As Diesel fuel pump nozzles may be
different in other countries, the presence
of the misfuel prevention device may
make refuelling impossible.
Before travelling abroad, we recommend
that you check with the CITROËN dealer
network, whether your vehicle is suitable
for the fuel pumps in the country in
which you want to travel.

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 its
compartment,

)
check that the warning lamp is on green,

)
connect your multimedia or other electrical
device (telephone charger, laptop computer,
CD-DVD player, baby food warmer...).
This socket works with the engine running, as
well as in STOP mode on Stop & Start.
In the event of 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-way
connector).
Connect only devices with class II
insulation (shown on the device).
As a safety measure, when electrical
consumption is high and when
required 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.

Safety









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 the
resistance 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 automatically
each time the vehicle is star ted.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on
snow: intelligent traction control.

This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control
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 sur faces offering low
levels of adhesion.

Seat belt unfastened warning
lamp in the instrument panel
This warning lamp comes on in the
instrument panel when one or more rear
passengers unfasten their seat belt.
From approximately 12 mph (20 km/h),
this warning lamp flashes for two minutes
accompanied by an audible signal of increasing
volume. Once these two minutes have elapsed,
this warning lamp remains on until the one or
more rear passengers fasten their seat belt.

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
, 4
and 5
come on in red, accompanied
by an audible signal and a message in the
screen, if a rear passenger has unfastened
their seat belt.

Electric parking brake


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

Application is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),

- Manual Application/Release

The parking brake can be applied/released
manually by pulling control lever A
.
Do not place any object (packet of
cigarettes, telephone...) between the
gear lever and the electric parking
brake control lever.
It is recommended that you do not
apply the parking brake in very cold
conditions (ice) and during towing
(breakdown, caravan...). Deactivate the
automatic functions and release the
parking brake manually.

If this warning lamp comes on in
the instrument panel, the automatic
mode 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 when
you press the accelerator can be deactivated.
Activation/deactivation is done
using the vehicle configuration
menu; refer to the section covering
the configuration of your vehicle's
systems.
The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible signal and a message is
displayed if the brake is not applied.

193Driving
With the ignition on or the engine running, to
release the parking brake, press
on the brake

pedal
or the accelerator, pull then release

control A
.


Manual release


Before leaving the vehicle, ensure
that parking brake warning lamp in
the instrument panel is on fixed, not
flashing.



Manual application

With the vehicle stationary, to apply the parking
brake whether the engine is running or off, pull

control lever A
.
The application of the parking brake is
confirmed by:


- illumination of the braking warning
lamp and of the P
warning lamp in
the control lever A
,

- display of the message
"Handbrake on".
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case
of an automatic gearbox with the gear lever in
position P
. The full application of the parking brake is
confirmed by:


- the braking warning lamp and
the P
warning lamp in the control
lever A
going off,

- display of the message
"Handbrake off".

If you pull control lever A
without pressing
the brake pedal, the parking brake will
not be released and a warning lamp will
come on in the instrument panel.


Maximum application

If necessary, you can make a maximum
application
of the parking brake. This is
obtained by means of a long pull
on the control
lever A
, until you see the message "Handbrake
on maximum" and a beep is heard.

Maximum application is essential:



- in the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,

- when the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing),

In the case of towing, a loaded vehicle
or parking on a gradient, make a
maximum application of the parking
brake then turn the front wheels
towards the pavement and engage a
gear when you park.
After a maximum application, the
release time will be longer.
