Opening the bonnet
Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid the risk of injury related
to an automatic change to START
mode.
Driving on flooded roads
Before driving through a flooded road,
it is strongly recommended that you
deactivate the Stop & Start system.
For more information on Driving
advice, particularly on flooded roads,
refer to the corresponding section.
At any time, press the "ECO OFF"

switch to
deactivate the system.
This is confirmed by the switch warning lamp
coming on, accompanied by the display of a
message.
Press the "ECO OFF" switch again.
The system is active again; this is
confirmed by the switch warning lamp
going off and the display of a message.
In certain circumstances, such as the need
to maintain a comfortable temperature in the
passenger compartment, it may be useful to
deactivate the Stop & Start system.
The system can be deactivated at any time,
once the ignition is on.
Deactivation / Manual reactivation
If the engine is in STOP mode, it then
restarts.
The Stop & Start system is
automatically reactivated every time the
ignition is switched on.

Operating fault
In the event of a malfunction with the system,
the "ECO OFF" switch warning lamp flashes
for a few seconds, then comes on continuously.
Have it checked by a CITROËN dealer or a
qualified workshop.In the event of a fault in STOP
mode, the vehicle may stall. All of
the instrument panel warning lamps
come
on.
Depending on version, an alert
message may also be displayed
asking you to put the gear selector into
position

N and to put your foot on the
brake pedal.
It is then necessary to switch off the
ignition, then restart the engine using
the key.
The Stop & Start requires the use of a
12 V battery of special technology and
characteristics.
All work on this type of battery must
only be carried out by a CITROËN
dealer or a qualified workshop.
For more information on the
12
V batter y, refer to the corresponding
section.

F Press button 4 to select "LIMIT" speed limiter
mode.
The selection is confirmed by the display of the
" LIMIT " function in zone A of the instrument panel.
Activation
F Press button 3 when the desired maximum
speed is displayed.
The information "ON" then appears in zone A
of the instrument panel.
When the function is selected, the
last memorised speed and the
information
"

PAUS E " are displayed.
With the engine running, you can adjust the
memorised maximum speed, displayed in
zone

A , by pressing:
F

Button 1 to increase the memorised
maximum speed.
F

Button 2 to decrease the memorised
maximum speed.
Successive presses will modify the limit
speed setting in steps of 1 mph (km/h) and a
continuous press in steps of 5 mph (km/h).
Programming
F Press button 3 .
This action causes the information " PAUS E " to

The accelerator pedal has a stiff point at the
end of its travel. To exceed the maximum speed
setting at any time, you can press the pedal

driving Operating fault
If there is a fault, a message is displayed
accompanied by an audible signal and
illumination of the SERVICE
warning lamp.
Have it checked by a CITROËN dealer or a
qualified workshop.
Exceeding the programmed
speed
In the event of a steep descent or
under excessive acceleration, the
speed limiter (which does not act
on the brakes) may not be able to
prevent the vehicle from exceeding the
programmed speed.
Use of a floor mat other than that
recommended by CITROËN may affect
the normal operation of the accelerator
pedal and hamper the operation of the
speed limiter.
Floor mats approved by CITROËN
are fitted with a 3rd fixing located in
the pedal area to avoid any risk of
inter ference with the pedals.
The speed will also flash if the speed limiter is
not able to prevent the vehicle from exceeding
the programmed speed setting (e.g. on a steep
descent or under excessive acceleration).
To reactivate the speed limiter, release the
accelerator to slow to a speed lower than the
programmed speed. F

Lane departure warning system
This system is particularly useful on motor ways
and main roads.
Activation
F When switching the ignition on or with the engine running, press this button; the
indicator lamp comes on.
Deactivation
F Press this button again, the indicator lamp goes off.
The status of the system remains in the
memory when the ignition is switched off.
Detection
You are warned by the vibration of the driver's
seat cushion:
-

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

o
n the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted 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 (e.g. arrow) or non-standard marking
(e.g. graffiti) is crossed.
Operating fault
In the event of a malfunction, the service
warning lamp comes on, accompanied by an
audible signal and a message in the screen.
Contact a CITROËN dealer or a qualified
workshop.
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)).
The detection may be impeded:
-
i
f the sensors are dirty (mud, snow...),
-
i

f the markings on the ground are
worn,
-
i

f there is little contrast between the
markings on the ground and the road
sur face.
The lane departure warning system
cannot in any circumstances replace
the need for vigilance on the part of the
driver.
It is necessary to observe driving
regulations and take a break every
two

hours.

"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.

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 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.
The use of snow tyres is strongly
recommended on sur faces with low
adhesion.
