The
system uses engine braking to slow your vehicle and then hold it at the speed of
t
he vehicle in front so as to maintain the programmed inter-vehicle time.
The
regulation range is limited to a maximum difference of 20 mph (30 km/h)

When the active 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
y
our vehicle the new cruise speed setting, rather than by pressing button 4 (on/pause) which reactivates the cruise control using the old cruise
s
peed setting, which may be very different from the current speed of your vehicle.

The active cruise control uses only engine braking to slow the vehicle. Consequently the
v
ehicle looses speed slowly, as when releasing
t
he accelerator pedal.
The
system is paused automatically:
-
i
f the vehicle in front slows down to much
o
r too suddenly, and the driver does not
b
rake,
-
i
f a vehicle comes between your vehicle
a
nd the vehicle in front,
-
i
f the system does not slow the vehicle
e
nough to continue to maintain a safe
d
istance, for example when descending a
s
teep hill.
Limits of operation
As the radar's field of view is quite narrow, it is possible that the system may not detect:
The
cruise control does not take account of:
-
s
tationary vehicles,
-
v
ehicles driving in the opposite direction.
-
v
ehicles of reduced width, such as
m
otorcycles, for example,
-
v
ehicles not running in the middle of
t
he
lane, -
v
ehicles entering a corner,
-
v
ehicles changing lane at the last moment.

In the event of a fault with the active cruise
control, you are alerted by an audible signal
a
nd display of the message message "Driving
a
id functions fault".
Have
the system checked by a CITROËN
d
ealer or a qualified workshop. When
the cruise control is working, take
c
are if making a maintained press on
o
ne of the cruise control programmed
s
peed modification buttons: this can
l
ead to a very quick change in the
s
peed of your vehicle.
do n
ot use the active cruise control on
slippery
sur faces or in heavy traffic.
When
descending a steep hill, the
c
ruise control may not be able to
p
revent the vehicle from exceeding the
pro
grammed
s
peed.
When
ascending a steep hill or when
t
owing, it might not be possible to attain
o
r maintain the programmed speed.
The
use of mats not approved by
C
ITROËN may inter fere with the
o
peration of the cruise control.
To
avoid any risk of jamming the pedals:
-
e
nsure that mats are secured
c
o r r e c t l y,
-
n
ever fit one mat on top of another.
Operating fault
The operation of the radar, located in the front bumper, may be disturbed by
a
ccumulations of grime (dust, mud...) or
i
n certain weather conditions
(snow,
i
ce...).
The
message "SYSTEM INACTIVE:
V
isibility reduced" is displayed to signal
t
hat the system has been put into
s
t a n dby.
Clean
the front bumper regularly.

The change from one level of alert to the next takes place if the driving
c
onditions do not change (speed
u
nchanged, no change of lane...)
Severe
weather conditions (very heavy
r
ain, accumulation of snow in front
o
f the radar) may inter fere with the
o
peration of the system, resulting in
t
he display of the message "System
inactive: Reduced visibility ".
The

ystem remains unavailable until the

If
the speed of your vehicle is too high
w
hen approaching another vehicle, the
f
irst level of alert may not be displayed:
t
he level 2 alert may be displayed
d
i r e c t l y.
On
the other hand, the level 1 alert
i
s never displayed with the triggering
t
hreshold 3 (close).
Alerts
According to the collision risk detected by the system and the alert threshold chosen, three
l
evels of alert can be triggered.
Level 1 :
visual alert only (orange)
i
ndicating that the vehicle in front is
v
ery close. The message "Vehicle
close "
is displayed.
Level 2 :
visual (red) and audible
a
lerts indicating that a collision is
i
mminent. The message "Brake! " is
displayed.
This
level of alert is based on the inter-vehicle
t
ime between your vehicle and the one in front.
This
level of alert is based on a time before
c
ollision. It takes account of the vehicle
d
ynamics, the speed of your vehicle and
t
he speed of the vehicle in front, the driving
c
onditions, the situation with your vehicle
(
cornering, pedals pressed, etc.) to trigger the
a
lert at the right moment. Level 3
: an increase in t
he tension of the driver's
s
eat belt, to hold the driver
a
gainst the backrest of their
sea
t.
The
3
rd level of alert is not triggered or i
s
interrupted in the event of an impact
b
etween the two vehicles.
The increase in the tension of the
driver's
seat belt is intended only as an
a
lert:
it
does not in any circumstances
a
ssure
the function of driver safety.
The
triggering of this alert does not act
o
n
the
safety functions provided by the
s
eat
belts.

operation of the radar, located in

a
ccumulations of grime (dust, mud...) or
i

This system indicates the proximity of an obstacle (person, vehicle, tree, gate, etc.)
w
hich comes within the field of detection of
s
ensors located in the bumper.
Certain
types of obstacle (stake, roadworks
c
one, etc.) detected initially will no longer be
d
etected at the end of the manoeuvre due to
t
he presence of blind spots.
Parking sensors
This function cannot, in any
circumstances, take the place of the
v
igilance of the driver. The
system is switched on by engaging reverse
g
ear. This is accompanied by an audible signal.
The system is switched off when you come out
o
f reverse gear.
Audible assistance
The proximity information is given by an i
ntermittent audible signal, the frequency of w
hich increases as the vehicle approaches the
obstacle.
The
sound emitted by the speaker (right or left)
i
ndicates the side on which the obstacle is located.
When
the distance between the vehicle and
t
he obstacle becomes less than approximately
t
hirty centimetres, the audible signal becomes
c
ontinuous.
Rear parking sensors
Visual assistance
This supplements the audible signal by d isplaying bars in the screen or the instrument
p
anel which move progressively nearer to
t
he vehicle. When the obstacle is near, the
"
Danger" symbol is displayed.
