Advice
The incorrect installation of a child seat in
a vehicle compromises the protection of
the child in the event of an accident.
Ensure that there is no seat belt or seat
belt buckle under the child seat, as this
could destabilise it.
Remember to fasten the seat belts or the
child seat harnesses keeping the slack
relative to the child's body to a
minimum,
even for short journeys.
When installing a


child seat using the seat
belt, ensure that the seat belt is tightened
correctly on the child seat and that it
secures the child seat firmly on the seat
of your vehicle. If your passenger seat is
adjustable, move it forwards if necessary.
The head restraint must be removed
before installing a
child seat with
a
backrest on a passenger seat.
Ensure that the head restraint is stored or
attached securely to prevent it from being
thrown around the vehicle in the event
of sharp braking. Refit the head restraint
when the child seat is removed. Children at the rear
At rear seating positions, always leave
sufficient space between the front seat
and:
-

a "
rear ward facing" child seat,
-

t
he child's feet for a child seat fitted
"forward facing".
To do this, move the front seat for wards
and, if necessary, straighten its backrest.
For optimal installation of the "forward
facing" child seat, verify that its backrest is
as close as possible to the backrest of the
vehicle seat, if possible in contact with it.
Children at the front
The legislation on carrying children on the
front passenger seat is specific to each
country. Refer to the legislation in force in
the country in which you are driving.
Deactivate the front passenger airbag
when a "rear ward facing" child seat is
installed on the front passenger seats.
Other wise, there is a
risk of serious or
fatal injury to the child if the airbag is
deployed.
Safety

131
Switching the ignition on
(without starting)
With the electronic key in the reader or the
Keyless Entry and Starting key inside the
vehicle, pressing the "START/STOP" button,
with no action on the pedals, allows the
ignition to be switched on.
F

P
ress the "START/STOP" button, the
instrument panel comes on but the engine
does not start.
F

P
ress the button again to switch off the
ignition and allow the vehicle to be locked.
With the ignition on, the system
automatically changes to energy economy
mode when required to maintain an
adequate state of charge of the battery.
On certain versions with the automatic gearbox
(EAT6/EAT8), the steering column does not
lock.
Electric parking brake
The technology adopted for the electric
parking brake does not allow the fitment of
15-inch wheels.
Indicator lamp
This indicator lamp comes on in the
instrument panel and in the control
lever to confirm the application of
the parking brake. It goes off to confirm the release of the parking
brake.
The indicator lamp in the control lever flashes
during manual application or release.
After applying the parking brake, the
simultaneous flashing of the indicator lamps
in the instrument panel and in the control lever
warns you to secure the immobilisation of the
vehicle by engaging a
gear (with a manual
gearbox or by placing the selector at position
P with an automatic gearbox or by placing
a chock against one of the wheels (e.g. parking
on a very steep slope or a steep slope with
a weak battery).
In the event of a battery failure, the
electric parking brake no longer works.
As a safety measure, if the parking brake
is not applied, immobilise the vehicle by
engaging a

gear (with a

manual gearbox)
or placing a chock against one of the
wheels.
Call a CITROËN dealer or a qualified
workshop.
The system provides, in automatic operation,
the application of the parking brake on
switching off the engine and release as the
vehicle moves off.
The driver can take over at any time to apply
or release the parking brake, by operating the
control lever:
-

b

y briefly pulling
the control lever to apply
the brake,
-

b

y briefly pushing
the control lever, while
pressing the brake pedal, to release it.
Automatic mode is activated by default.

The speed limit units (mph or km/h)
depend on the country you are driving in.
This should be taken into account in order
to obser ve the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in.
The automatic reading of road signs is
a driving assistance system and does not
always display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system cannot in any circumstances
replace the need for vigilance on the part
of the driver.
The driver must observe the driving
regulations and must adapt the speed of
the vehicle to suit the weather and traffic.
The system may not display the speed
limit if it does not detect a
speed limit sign
within a
preset period.
The system is designed to detect signs
that conform to the Vienna Convention on
road signs. To maintain correct operation of the
system: regularly clean the area in front of
the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Activation/Deactivation
Activation and deactivation of the system is
done in the touch screen's Driving
menu.
Select the " Vehicle settings " tab, then
" Security "/ "Safety " and "Recommended
speed display ".
Displays in the instrument panel
1.Detected speed limit indication.
or
2. Indication of the end of the speed limit. The system is active but is not detecting speed
limit information.
On detection of speed limit information, the
system displays the value.
Operating limits
The legislation on speed limits is specific to
each country.
The system does not take account of reduced
speed limits in the following cases:
-

p
oor weather (rain, snow),
-
a

tmospheric pollution,
-
w

hen towing,
-

d

When the cruise control is switched on, be
careful if you maintain the pressure on one
of the programmed speed modification
buttons: this may result in a very rapid
change in the speed of your vehicle.
Do not use the cruise control on slippery
roads or in heavy traffic.
When descending a


steep hill, the cruise
control system cannot prevent the vehicle
from exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached
or maintained.
The use of mats not approved by
CITROËN may inter fere with the operation
of the cruise control.
To avoid any risk of jamming of the pedals:
-

e
nsure that mats are secured correctly,
-

n
ever fit one mat on top of another.Adaptive cruise control
The system allows the speed of
your vehicle to be maintained at the
setting you have made, and also to
respect the inter-vehicle time that
you have selected between your
vehicle and the one in front, when
the situation permits it.
Switching between the
types of cruise control
The choice between "adaptive" and "standard"
cruise control is made in the Driving menu.
F

n the Driving menu, select the Driving
functions tab and then Active cruise
control to activate or deactivate adaptive
cruise control.
For more information on the Cruise
control , refer to the corresponding
section.
Principles of operation
Using radar with a range of about 100 metres,
l ocated at the front of the vehicle, this system
detects a
vehicle travelling in front of your
vehicle.
It automatically adapts the speed of your
vehicle to that of the vehicle in front.
If the vehicle in front is travelling more slowly,
the system progressively reduces the speed of
your vehicle using just engine braking (as if the
driver had pressed the " -" b u t to n).
If your vehicle is too close to the vehicle in
front or is approaching it too quickly, adaptive
cruise control is automatically deactivated.
The driver is then alerted by an audible signal
accompanied by a


message.
If the vehicle in front accelerates or changes
lane, the adaptive cruise control gradually
accelerates your vehicle to return to the
programmed speed.
If the driver operates the direction indicator to
the left (left-hand drive) or to the right (right-
hand drive), to overtake a
slower vehicle, the
adaptive cruise control allows your vehicle to
temporarily approach the vehicle in front to
assist the overtaking manoeuvre, though never
exceeding the programmed speed.
The adaptive cruise control operates
by day and at night, in fog or moderate
rainfall.

change in the speed of your vehicle.
Do not use adaptive cruise control on
slippery sur faces or in heavy traffic.
When descending a


steep hill, the cruise
control system cannot prevent the vehicle
from exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached
or maintained.

n
ever fit one mat on top of another. Operation of the radar, located in the
front bumper, may be impaired by the
accumulation of dirt (dust, mud, etc.) or in
certain weather conditions (snow, frost,
e t c .) .
The message "SYSTEM INACTIVE:
Reduced visibility". is displayed to indicate
that the function is in standby.
Clean the front bumper regularly.
If the front bumper is to be repainted or
retouched, contact a
CITROËN dealer
or a
qualified workshop. Certain types of
paint could inter fere with the operation of
the radar.
Adaptive cruise control

mph (30 km/h)
Function until vehicle is stopped : with
automatic gearbox
Function until 19
mph (30 km/h): with manual
gearbox This system provides the following
functions:
-

A
utomatically maintains the
vehicle at the speed set by the
driver.
-
A
utomatic adjustment of the
distance between your vehicle
and the one in front.
Cruise control remains active after
changing gear regardless of the gearbox
type.
It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system. With an automatic gearbox, automatic
adjustment of the distance can cause your
vehicle to come to a complete stop.
For this purpose there is a radar installed in the
front bumper.

that you always adapt your speed and
your safety distance from vehicles ahead
according to the driving conditions, the
weather and the road surface.
Use the cruise control only where
the driving conditions allow running
at a
constant speed and keeping an
adequate safety distance.
Do not activate the cruise control in urban
areas where pedestrians are likely to
cross the road, in heavy traffic, on winding
or steep roads, on slippery or flooded
roads, when there is snowfall, if the front
bumper is damaged or when the brake
