etection of a vehicle that is too close or running at a speed lower than your

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)
b
etween the speed setting and the speed of the vehicle ahead.

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

In the event of a fault with the active cruise
control, you are alerted by an audible signal

the system checked by a CITROËN
d
ealer or a qualified workshop. When
the cruise control is working, take

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,

Collision risk alert
System providing a warning to the driver that their vehicle is at risk of collision with the vehicle in front.
T he collision risk alert system can be activated
o
r deactivated by the driver.
From
the secondary page of the "Driving
assistance "
menu:
F
s
elect the "Vehicle settings "
menu,
F
c
heck the "Collision risk alert "
line and
c
onfirm.
This
system has been designed to
i
mprove driving safety.
It
is the responsibility of the driver to
k
eep a constant check on the state of
t
he traffic, to assess the relative speed
a
nd distance of other vehicles.
The
collision risk alert system can never
r
eplace the need for vigilance on the
p
art of the driver.
This
system operates from 20 mph
(
30 km/h), only when other vehicles are
r
unning in the same direction as your
v
ehicle; the system does not detect
s
tationary objects. A radar is fitted at
t
he front of the vehicle. The
alert thresholds determine how you want to
b
e alerted to the presence of a vehicle running
i
n front of you.
You
can choose from three thresholds:
-
1
: "Distant", to be given an early alert
(
cautious
d
riving).
-
2
: "Normal".
-
3
: "Close", to be given a later alert
(sporty
driving).
Setting the thresholds for
the alert
This function can be deactivated permanently by a CITROËN dealer or a
q
ualified
w
orkshop.
From
the secondary page of the "Driving
assistance "
menu:
F

menu,
F

to memorise the threshold and

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
s
ystem remains unavailable until the
m
essage
d
isappears.
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

n
the
safety functions provided by the
s
eat
belts.

Lane departure warning system
System which, using a camera which recognises solid or broken lines, detects the
i
nvoluntary crossing of longitudinal traffic lane
m
arkings on the ground.
To
provide safe driving, the camera analyses
t
he image then, if the driver's attention drops,
t
riggers a warning if the vehicle drifts over
a
lane marking (speed higher than 50 mph
(
80 km/h)).
This
system is particularly useful on motor ways
a
nd main roads. Activation
and deactivation of the function is
d
one in the "
Driving assistance " menu of the
t
ouch screen tablet.
Activation / deactivation
The driver is alerted by vibration of the seat belt (
at the level of the reel).
No
warning is transmitted while the direction
i
ndicator is active and for approximately
2
0 seconds after the direction indicator is
s
witched off.

t
he need for vigilance and responsibility
o
