System which reduces fuel consumption by advising the driver to change up.
The system intervenes only when driving
economically.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one or more gears. You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. In fact, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal
moderately. The information appears in the instrument
panel in the form of an arrow accompanied by
the suggested gear.
Gear shift indicator*
In the case of driving which makes
particular demands on the per formance
of the engine (firm pressure on the
accelerator pedal, for example, when
overtaking...), the system will not
recommend a gear change.
The system never suggests:
-

e
ngaging first gear,
-
enga

ging reverse gear,
-

e
ngaging a lower gear.
Operation
* Depending on engine. -
T
he system may suggest that you engage
a higher gear, if appropriate.
With an electronic or automatic
gearbox, the system is only active in
manual mode.

Stop & Start
Operation
- with an electronic gearbox, at speeds
below 4 mph (6 km/h), press the brake
pedal or put the gear lever in position N .
Going into engine STOP
mode
The "ECO" warning lamp comes
on in the instrument panel and the
engine goes into standby:
If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It rests itself
to zero every time the ignition is
switched on with the key.
Special cases: STOP mode not
available
In this case, the "ECO" warning
lamp flashes for a few seconds then
goes
off.
This operation is perfectly normal. STOP mode is not invoked when:
-

t

he driver's door is open,
-

t

he driver's seat belt is not fastened,
-

t

he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start using
the key,
-

t

he electric parking brake is applied or
being applied,
-

t

he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d

emisting is active,
-

s

ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
The Stop & Start

system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
The

engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key. For your comfort, during parking
maoeuvres, STOP mode is not
available for a few seconds after
coming out of reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as for
example, braking, power steering...

Reactivation
In the event of a fault with the system,
the "ECO OFF" switch warning lamp flashes
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 the instrument panel
warning lamps come on. It is then necessary
to switch off the ignition and start the engine
again using the key.
Operating fault Maintenance
This system requires a 12 V battery with a
special specification and technology (reference
numbers available from CITROËN dealers).
Fitting a battery not listed by
CITROËN
introduces the risk of malfunction of
the system.
To charge the battery, use a 12 V charger and
observe the polarity. Before doing anything under the
bonnet, deactivate the Stop & Start
system to avoid any risk of injury
resulting from automatic operation of
START mode.
The Stop & Start system makes use of
advanced technology. For any work on
the system go to a qualified workshop
with the skills and equipment required,
which a CITROËN dealer is able to
provide.
The system is reactivated automatically
at every new start using the key.
Press the "ECO OFF" switch again.
The system is active again; this is confirmed
by the switch warning lamp going off and a
message in the screen.

Overriding 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 (e.g. on a steep
descent or under excessive acceleration).
To reactivate the speed limiter, release the

"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

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.

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.
