"Hydractive III +" electronic suspension
The suspension automatically and instantly
adjusts to different driving styles and to
the profile of the road, providing the best
compromise between occupant comfort and
vehicle road holding.
The system alternates between soft and firm
suspension settings, maximising comfort at the
same time as constantly ensuring the highest
level of safety. It also automatically corrects
ride height, according to the vehicle load and
driving conditions.
In addition, the "Hydractive III +" system
allows you to choose between two modes of
suspension.
A change of suspension mode can be made
either when the vehicle is moving or when
stationary, by pressing button A.
Display in the instrument panel
The suspension mode selected is displayed in
the instrument panel screen.
Normal mode
This mode favours soft damping for
maximum comfort.
If the speed authorised for a
particular position is exceeded, the
vehicle reverts automatically to the
normal road position.
SPORT mode
This mode favours dynamic driving. T
he warning lamp on button A comes
on in addition to the message in the
instrument panel screen.
SPORT mode is retained when you
switch off the engine.
Vehicle positions
Position changes may only be made when
the engine is running.
The adjustable ground clearance meets all
types of situation. Apart from a few specific
situations, the vehicle should be in the Normal
position.

Lighting left on
When a front door is opened with the
ignition off and in manual lighting mode,
an audible signal warns the driver if the
vehicle's lighting is still on.
In this case, switching off the lighting
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, they will switch
off automatically after thirty minutes to
prevent discharging of the battery.* According to country.

Trajectory control systems
Anti-slip regulation (ASR) and dynamic stability control
(DSC)
Activation
This is indicated by flashing of this
warning lamp in the instrument panel.
Your vehicle has a system to improve traction
on snow: intelligent traction control
.
This system detects situations of low adhesion
that might make moving off and progress
difficult on deep fresh snow or compacted
snow.
In these situations the intelligent traction
control system regulates the amount of wheel
slip to optimise the traction and trajectory
control of your vehicle.
For vehicles with Hydractive III + suspension,
manual adjustment of ground clearance to
the intermediate position improves further the
ability to make progress in deep snow (see the
relevant paragraph).
The use of snow tyres is strongly
recommended on sur faces with low adhesion.
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.
Intelligent traction control
system ("Snow motion")
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.

Operating fault
Illumination of this warning lamp and
the lamp in the deactivation button,
accompanied by an audible signal
and a message, indicate a fault with
the system.
Deactivation

grip permits.F

Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The indicator lamp in the button comes on.
The DSC and ASR systems no longer act
on the operation of the engine and on the
brakes in the event of a involuntary change of
trajectory.
F

P
ress this button again.
The systems are reactivated automatically each
time the ignition is switched back on or from
30
mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate
them manually:
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate
the DSC and ASR, so that the wheels can turn
freely and regain grip.

Fuel tank
Capacity of the tank: approximately 71 litres*.
Low fuel level
When the minimum level
in the tank is reached, this
warning lamp comes on in the
instrument panel, accompanied
by an audible warning and a message in the
multifunction screen. When it first comes on,
there remains around 5 litres of fuel in the tank.
You must refuel to avoid running out of fuel.

While you are refuelling, the engine must be
stopped and the ignition switched off.
For a petrol engine with a catalytic
converter, unleaded fuel is compulsory.
Opening the fuel flap Refuelling
* 55 litres for Slovakia. Additions of fuel must be of at least
5 litres to be taken into account by the
fuel gauge.
The filler neck is narrower to ensure
that only unleaded petrol nozzles can
be put in.
Opening the filler cap may create a
noise of an inrush of air. This vacuum,
which is entirely normal, is caused by
the sealing of the fuel system.
With Stop & Start, never refuel with the
system in STOP mode; you must switch
off the ignition with the key.

Misfuel prevention (Diesel)*
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.
* According to 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
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
s l ow l y.

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).
Travelling abroad
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.
