No vehicle detected:
the system operates as a
standard cruise control.
Detection of a
vehicle, at the limit of the range of the radar:
the system operates as a
standard cruise control.
"SPEED
ADJUSTED" Detection of a
vehicle that is too close or running at a speed lower than your vehicle's
cruise speed setting.
The system uses engine braking to slow your vehicle and then hold it at the speed of the
vehicle in front so as to obser ve the programmed inter-vehicle time.
The regulation range is limited to a
maximum difference of 19 mph (30 km/h) between the
cruise speed setting and the speed of the vehicle in front.
"SPEED
ADJUSTED" When the adjusted speed reaches the limit of regulation (speed setting – 19
mph
(30
km/h)), the adjusted speed flashes together with the speed setting to signal that
automatic deactivation of the system is imminent.
"Cruise control
paused". If the system exceeds the limit of speed adjustment that it can make and in the absence of
any reaction by the driver (operation of the direction indicator, change of lane, reduction in
the speed of the vehicle), the system is automatically paused.
The display of the deactivation message is accompanied by an audible signal.

The adaptive cruise control uses only engine
braking to slow the vehicle. Consequently the
vehicle loses speed slowly, as when releasing
the accelerator pedal.
The system is paused automatically:
-
i
f the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
-

i
f a vehicle comes between your vehicle and
the vehicle in front.
The regulation range is limited to a maximum
d ifference of 19 mph (30 km/h) between the
cruise speed setting and the speed of the
vehicle in front. Above this, the system goes into
pause if the safety distance becomes too short.
Poor weather conditions (very heavy
rain, accumulation of snow in front of the
radar) may hinder the operation of the
system, with the display of the operating
fault message "SYSTEM INACTIVE:
Reduced visibility". The function remains
unavailable until the message disappears.
Since the radar detection range is relatively
narrow, it is possible that the system cannot
detect:
-

v
ehicles of reduced width, such as
motorcycles, for example, -

v
ehicles not running in the middle of the
lane,
When the adaptive cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored. The message "Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the function be
reactivated by pressing button 2

or 3,

which will make the current speed of your
vehicle the new cruise speed setting,
rather than by pressing button 4 (on /
pause) which reactivates the cruise control
using the old cruise speed setting, which
may be very different from the current
speed of your vehicle.
Operating limits
- if the system does not slow the vehicle enough to continue to maintain a safe
distance, for example when descending
a
steep hill.
-
v

ehicles entering a

corner,
-

v
ehicles changing lane at the last moment.
The cruise control does not take account of:
-
s

tationary vehicles,
-

v
ehicles driving in the opposite direction.
Malfunction
In the event of a malfunction of the adaptive
c ruise control system, you are warned by an
audible signal and the display of the message
"Driving aid functions fault".
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
Driving

157
When the cruise control is working, take
care if keeping pressed one of the cruise
control programmed speed change
buttons: this can lead to a very rapid
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.
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. 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
until vehicle is stopped/
until 19
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.

Driving

158
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.
