In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle is
still below 6 mph (10 km/h).
The front parking sensors are interrupted if the
vehicle stops for more than three seconds in
forward gear, if no further obstacles are detected
or when the speed of the vehicle exceeds 6 mph
(10 km/h).

Front parking sensors

The function is deactivated by pressing this
button. The indicator lamp in the button
comes on.
Pressing this button again reactivates the
function. The indicator lamp in the button
goes off.

Operating fault

In the event of a malfunction of
the system, when reverse gear
is engaged this warning lamp is
displayed in the instrument panel
and/or a message appears in the
screen, accompanied by an audible
signal (short beep).
Contact a CITROËN dealer or a
qualified workshop.

The sound emitted by the speaker (front or
rear) indicates whether the obstacle is in front
or behind.

The function will be deactivated
automatically if a trailer is being towed
or a bicycle carrier is fitted (vehicle
fitted with a towbar or bicycle carrier
recommended by CITROËN).

In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.

Fuel

Capacity of the tank: approximately 60 litres.

When the low fuel level in the
tank is reached, 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, around
6 litres

of fuel remain in the tank.

Low fuel level

Additions of fuel must be of at least 5 litres to
be registered by the fuel gauge.
Opening the filler cap may result in an inrush of
air. This vacuum is entirely normal and results
from the sealing of the fuel system.

F Press control A

until the automatic opening

of the fuel flap is heard.

This control remains active for a few
minutes after switching off the ignition. If
necessary, switch the ignition on again to
reactivate it.

F

Take care to select the pump that delivers

the correct fuel for your vehicle.

If you are filling your tank to the top, do not
persist after the third cut-off; this could
cause your vehicle to malfunction.

F Introduce the nozzle so as to push in the

metal non-return flap B.

F

Make sure that the nozzle is pushed in as

far as possible before starting to refuel (risk
of blowback).

F

Maintain this position while refuelling.

F

Push the fuel flap to close it.

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.

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.
If you run out of fuel (Diesel), refer to the
corresponding section.

C4-2_en_Chap07_infos-pratiques_ed02-2015

Fuel used for petrol
engines

The petrol engines are compatible with
E10 bio-petrol (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.

Fuel used for Diesel
engines

The Diesel engines are compatible with
biofuels which conform to current and future
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).
B30 biofuel can be used in certain Diesel
engines. However, this use, even occasional,
requires strict application of the special
servicing 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).

The petrol or Diesel engine of your vehicle is
fitted with a catalytic converter, 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 a
collision.

If you have put in the wrong fuel for
your vehicle, you must have the tank
drained and refilled with the correct
fuel before you start the engine.

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.

* Depending on the country of sale.

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 CITROËN dealer network,
whether your vehicle is suitable for the
fuel pumps in the country in which you
intend to travel.

For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.

It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.

The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.

Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.

Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road surface. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.
