When the cruise control is paused,
it can only be reactivated when all of
the safety conditions are met. The
message "Activation not possible,
conditions unsuitable" is displayed while
reactivation is not possible.
Wait until the speed of the vehicle
is close to the speed setting before
reactivating the system - by pressing
button 2 or 3 - in order to set your
current speed as the new speed setting.

As a precaution, it is recommended that
you select a cruise speed setting close
to the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.

Modification of the inter-vehicle distance setting
Three predefined inter-vehicle distance settings
are offered:
-
"
Distant" (3 dashes),
-

"
Normal" (2 dashes),
-

"
Close" (1 dash). Engine running and cruise control selected
(grey), you can modify the inter-vehicle
distance setting:
F

p
ress button 6 to display the selection
screen for inter-vehicle distance,
F
p
ress button 6 repeatedly to cycle through
the predefined settings.
The selection screen closes after a
few seconds.
The modification is then taken into account.
This setting remains in memory, whatever the
state of the system and when the ignition is
switched off.
It is possible to exceed the speed setting
temporarily by depressing the accelerator
pedal.
The cruise control no longer manages the
braking system during this period.
Simply release the accelerator pedal to return
to the programmed speed.
If the programmed speed setting is exceeded,
the display of the speed setting disappears
and a message "Cruise control suspended"
is displayed until the accelerator pedal is
released.

IndicatorDisplay Associated messageComment
+ "Take back control of the
vehicle"
The driver should take control of the vehicle by accelerating or
braking, depending on the circumstances.
+ "Take back control of the
vehicle"
The system cannot manage the critical situation alone
(emergency braking of the target vehicle, rapid insertion of
another vehicle between the two vehicles).
The driver must immediately take back control of the
vehicle.
or "Activation not possible,
conditions unsuitable"
The system refuses to activate the cruise control (speed outside
the operating range, winding road).
or according to the inter-vehicle
distance selected and the actual
distance from the target vehicle "Cruise control paused"
(for a few seconds)
The system has brought the vehicle to a complete stop and is
holding it immobilised.
The driver should accelerate to move off again.
The cruise control remains paused until the driver reactivates it
with the speed of the vehicle above 18 mph (30 km/h).

Operating fault
In the event of a fault with the cruise
control, you are alerted by the
illumination of this warning lamp
and the display of a message in the
instrument panel, accompanied by an
audible signal.
The cruise control operates by day and at night, in fog or moderate rainfall.
However, it is strongly recommended that you always keep a safe distance from vehicles
ahead, depending on the driving conditions, the weather and the road sur face.
Use the cruise control only where the driving conditions allow running at a constant speed
and at an adequate safe distance.
Do not use the cruise control in urban areas, heavy traffic, on winding or steep roads, on
slippery or flooded sur faces, in snow, if the front bumper is damaged or if the brake lamps
are faulty.
In certain circumstances, it may not be possible for the speed setting to be maintained or
even attained: loaded vehicle, ascending a steep hill, etc.
The system is not intended for the following situations:
-

t

he front end of the vehicle has been modified (addition of driving lamps, paint on the
bumper),
-

d

riving on a racing circuit,
-

r

unning on a rolling road,
-

u

se of snow chains, non-slip covers or studded tyres. Have the system checked by a CITROËN
dealer or a qualified workshop.
The operation of the radar, located in the front bumper, may be disturbed by accumulations
of grime (dust, mud...) or in certain weather conditions (snow, ice...).
The message "SYSTEM INACTIVE: Visibility reduced" is displayed to signal that the system
has been put into standby.
Clean the front bumper regularly.
When painting or touching up the paint on the front bumper, consult a CITROËN dealer or a
qualified workshop. Certain types of paint could hinder the operation of the radar. The use of mats not approved by CITROËN may inter fere with the operation of the cruise
control.
To avoid any risk of jamming the pedals:
-

e

nsure that mats are secured correctly,
-

n

ever fit one mat on top of another.

Limits of operation
In the following cases, it is recommended
that the system be deactivated in the vehicle
configuration menu:
-
w
hen towing a trailer or caravan,
-

w
hen carrying long objects on roof bars or
a roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling road
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-

f
ollowing impact damage to the windscreen
close to the detection camera,
-

i
f the front bumper has been damaged,
-

i
f the brake lamps are not working.Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified.
Consequently, the driver must always
remain attentive and able to react at any
time to avoid an accident. Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed:
the level 2 alert may be displayed
di r e c t l y.
Important
: the level 1 alert is never
displayed if the " Close" threshold has
been selected.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of alert can be
triggered and displayed in the instrument panel.
Level 1: visual alert only, signalling
to you that the vehicle in front is very
close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.
Modifying the alert trigger
threshold
This threshold determines how you wish to be
warned of the presence of a vehicle moving
or stationary in front of you, or a pedestrian
present in your traffic lane.
The current threshold can be modified only via
the Driving menu in the touch screen.
You can select one of three thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.

braking assistance
If the driver brakes, but not sufficiently to
avoid a collision, this system will complete the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
Deactivation / Activation
By default, the system is automatically
activated at every engine start.
The system can be deactivated or activated in
the vehicle settings menu in the screen. Deactivation of the system is
signalled by the illumination of this

Operating fault
In the event of a fault, you are alerted
by the illumination of this warning
lamp, accompanied by the display of
a message and an audible signal.
If the front bumper is to be repainted,
contact a CITROËN dealer or a
qualified workshop. Certain types of
paint could inter fere with the operation
of the radar. Clean the windscreen regularly,
particularly the area in front of the
camera.
Do not allow snow to accumulate on
the bonnet or roof of the vehicle as this
could mask the camera's view.
Clean the front bumper, removing mud,
snow, ... There may be inter ference in the
operation of the camera or it may not
work at all in the following situations:
-

p
oor visibility (inadequate street
lighting, falling snow, heavy rain,
dense fog, ...),
-

approaching vehicle on the other
side of the road, low sun, reflection
on a wet road, leaving a tunnel,
alternating between light and
shade, ...),
-

c
amera or radar masked (mud,
frost, snow, ...).
In these situations, detection
per formance may be reduced.
Check that the sensors (camera and radar) are
not covered by dirt, mud, frost, snow...
If the problem persists, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
