Primarily designed for driving on main
roads and motor ways, this system only
works on moving vehicles, driving in the
same direction as your vehicle.
Principle of operation
The system automatically adapts the speed of
your vehicle to that of the vehicle in front, to
maintain a


constant distance.
If the vehicle in front is driving more slowly, the
system slows or even stops your vehicle, using
engine braking and the braking system (for
versions fitted with an automatic gearbox).
If the vehicle in front accelerates or changes
lane, the cruise control progressively
accelerates your vehicle to return to the
programmed speed.
If the driver operates a
direction indicator to
overtake a
slower vehicle, the cruise control
allows your vehicle to temporarily approach
the vehicle in front to assist the overtaking
manoeuvre, though never exceeding the
programmed speed.
The brake lamps illuminate as soon as
the braking system is activated with
deceleration of the vehicle. This system is a
driving aid that cannot,
in any circumstances, replace the need to
obser ve speed limits and safety distances,
nor the need for vigilance on the part of
the driver.
Some vehicles present on the road may
not be properly seen or may be poorly
interpreted by the camera and/or radar
(e.g. a lorry), which may lead to a poor
assessment of the distances and lead to
the vehicle inappropriately accelerating or
braking.
The driver must be ready at all times
to retake control of their vehicle by
permanently holding both hands on the
steering wheel and keeping their feet near
the brake and accelerator pedals.

km/h) by pressing button 2
, 3

or 4
.
If the driver takes no action following this
immobilisation, the electric parking brake is
applied automatically after a

while (approx. five
minutes).
As a precaution, it is recommended
that you select a
cruise speed close to
the current speed of your vehicle, so
as to avoid any sudden acceleration or
deceleration of the vehicle.
Modification of the programmed
inter-vehicle distance

through the predefined settings.
The selection screen closes after a
few
seconds.
The modification is then accepted.
This setting remains in memory, whatever the
state of the system and when the ignition is
switched off.
The selection also applies to the stopping
distance (versions with EAT6
and
EAT8
automatic gearbox).
Three threshold settings are suggested for the
inter-vehicle distance:
-
"
Distant " (3 dashes),
- "
Normal " (2 dashes),
- "
Close " (1 dash).

Exceeding the programmed
setting
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.

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.
Malfunction
If the cruise control
malfunctions, dashes are
displayed instead of the
cruise control speed setting.
If this warning lamp comes
on, accompanied by an
alert message and an
audible signal, this confirms
a


malfunction.
The adaptive cruise control deactivates
automatically if the use of a "space-saver"
type spare wheel is detected or if there is
a

malfunction on the lateral brake lamps or
trailer brake lamps (for approved trailers).
The following situations may interfere with
the operation of the system or prevent it
from working:
-
p
oor visibility (inadequate street
lighting, falling snow, heavy rain, dense
f o g , e t c .),
-

d

azzle (headlamps of an oncoming
vehicle, low sun, reflections on a

damp
road, leaving a

tunnel, alternating
shade and light, etc.),
-

c

amera or radar masked (mud, frost,
snow, condensation, etc.).
In these situations, detection performance
may be reduced.
The message "SYSTEM INACTIVE:
Reduced visibility". is displayed to indicate
that the function is in standby. Have the system checked by a
CITROËN
dealer or a

qualified workshop.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
The system allows:
- t he driver to be warned that their vehicle is
at risk of collision with the vehicle in front,
-

a c
ollision to be prevented, or its severity to
be limited, by reducing the vehicle's speed.
This system is a
driving aid that includes three
functions:
-

C
ollision Risk Alert (alert if there is a risk of
collision),
-
I

ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).

The vehicle has a camera located at the top of
t he windscreen, and, depending on the version,
a radar located in the front bumper.
This system is designed to assist the
driver and improve road safety.
It is the driver's responsibility to
continuously monitor the state of the
traffic, observing the driving regulations.
This system does not replace the need for
vigilance on the part of the driver.
As soon as the system detects a
potential
obstacle, it prepares the braking circuit in
case automatic braking is needed. This
may cause a
slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically
activated at every engine start.
The system can be deactivated or activated via
the vehicle settings menu.
Deactivation of the system is
signalled by the illumination of this
indicator lamp, accompanied by the
display of a
message.
Operating conditions and
limits
The ESC system must not be faulty.
The ASR must not be deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required. The following situations may interfere with
the operation of the system or prevent it
from working:
-

p
oor visibility (inadequate street
lighting, falling snow, heavy rain, dense
f o g , e t c .),
-
d
azzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
-
c
amera or radar obstructed (mud, frost,
snow, condensation, etc.).
On versions with camera alone, this
message indicates to you that the camera
is obstructed: " Driving aids camera:
visibility limited, see user guide ".
In these situations, detection performance
may be reduced.
