Parking space sensor
System which measures the parking space
available between two vehicles or obstacles. It
measures the size of the space and gives you
information on:
-
t
he possibility of fitting into a free space,
depending on the dimensions of your
vehicle and the distances necessary for
your manoeuvring,
-

t
he level of difficulty of the manoeuvre to
be performed.
The system does not measure spaces which
are clearly much smaller or larger than the size
of the vehicle. The parking space sensor function warning
lamp can have three different states:
-

o
ff: the function is not selected,
-

o
n fixed: the function is selected but the
conditions for measuring are not yet met
(direction indicator not operating, speed too
high) or the measurement is terminated.
-

f
lashing: measurement is in progress or
the message is being displayed. You can select the "parking space sensor"
function by pressing button A
. The fixed
illumination of the warning lamp indicates that
the function is selected.
During the measurement, the message
"Measurement in progress - Vmax 20 km/h
(12 mph)" is displayed in the instrument panel
screen.Displays in the instrument panel

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.
When the speed of the vehicle is below about
6 mph (10 km/h), some sources of noise
(motorcycle, lorry, pneumatic drill, ...) may
trigger the audible parking sensor signals.
Reactivation
Deactivation

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

"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.

Automatic adjustment of directional
headlamps
The system then places your headlamps in the
lowest position. If a fault occurs, this warning lamp
comes on in the instrument panel,
accompanied by an audible signal
and a message in the instrument
panel screen.
Initial setting is position "0" .To avoid causing a nuisance to other road
users, this system corrects the height of the
xenon headlamp beams automatically and
when stationary, depending on the load in
the

vehicle. Do not touch the xenon bulbs. Contact
a CITROËN dealer or a qualified
workshop.
Travelling abroad
If planning to use your vehicle in a
country that drives on the other side
of the road, we recommend that
you contact a CITROËN dealer or a
qualified workshop to check whether
the headlamps need to be adjusted to
avoid dazzling on-coming drivers.

Programming
The function is activated or deactivated via the
instrument panel screen "Main Menu".
To do this, select " Vehicle parameters \
Lighting \ Directional headlamps".
Operating fault
If a fault occurs, this warning lamp
flashes in the instrument panel,
accompanied by a message in the
multifunction screen.
Directional headlamps
function
When the dipped or main beam headlamps are
on, this function, associated with the "cornering
lighting" function, enables the light beam to
follow the direction of the road.
The use of this function, linked with the xenon
headlamps only, considerably improves the
quality of your lighting when cornering.

When stationary or moving at very low
speed or when reverse gear is engaged,
the function is inactive.
The status of the function remains in the
memory when the ignition is switched off.

Braking assistance systems
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in particular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, it indicates a fault with
the anti-lock braking system which could result
in loss of control of the vehicle when braking.
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an
audible signal and a message in the
instrument panel screen, it indicates a fault with
the electronic brake force distribution which
could result in loss of control of the vehicle
when braking.
You MUST stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.
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.
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-

a

nti-lock braking system (ABS),
-

e

lectronic brake force distribution (EBFD),
-

e

mergency braking assistance (EBA).
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.When braking in an emergency, press
firmly without releasing the pressure.
When braking in an emergency,
press very firmly without releasing
the

pressure.

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.

Reactivation
Operating fault

accompanied by an audible signal
and a message, indicate a fault with
the system.
Deactivation

grip permits.F

P
ress this button.
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.
