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.

153
Pausing/Suspension of the
system
The driver must inter vene as soon as
they believe that the traffic conditions or
the state of the road sur face make this
necessary, by moving the steering wheel
to suspend the system temporarily. Any
action at the brake pedal which results in
the cruise control being paused will also
cause the system to be paused.
If the system detects that the driver is
not holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no reaction
from the driver.
After suspension due to the prolonged
release of the force holding the steering
wheel, you must reactivate the function by
pressing the button again. Automatic pausing:
-

T
riggering of the ESC.
-

Malfunctions
(orange
colour) A system malfunction is indicated
by the Ser vice warning lamp
coming on and this (orange) symbol,
accompanied by an alert message
and an audible signal.
Active Safety Brake with
Collision Risk Alert and
Intelligent emergency
braking assistance
Refer to the General recommendations on
the use of driving and manoeuvring aids
.
This system allows:
-

t
he driver to be warned that their vehicle is
at risk of collision with the vehicle in front,
a pedestrian or, depending on version, a
cyclist,
-

a c
ollision to be prevented, or its severity to
be limited, by reducing the vehicle's speed.
Driving

157
The system also takes motorcyclists and
animals into account; however, animals
below 0.5 m tall and objects on the road
are not necessarily detected.
This system is comprised of three functions:
-

C
ollision Risk Alert,
-
I

ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
The vehicle has a
multifunctional camera
located at the top of the windscreen, and,
depending on version, a radar located in the
front bumper. 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.
This system can be deactivated or
activated via the Driving /Vehicle
menu of the touch screen.
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 DSC/ASR systems must not be
deactivated.
All passenger seat belts must be fastened.
Driving at a steady speed on roads with few
bends is required. In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
-

t
owing a trailer,
-
c
arrying long objects on roof bars or roof
rack,
-
w
ith snow chains fitted,
-
b
efore using an automatic car wash, with
the engine running,
-
b
efore placing the vehicle on a rolling road
in a workshop,
-
t
owed vehicle, engine running,
-
d
amaged front bumper (version with radar),
-
f
ollowing an impact to the windscreen close
to the detection camera.
The system is automatically deactivated
after the use of certain "space-saver"
type spare wheels is detected (smaller
diameter).
The system is automatically deactivated
after detection of a fault with the brake
pedal switch or with at least two brake
lamps.
It is possible that warnings are not given,
are given too late or seem unjustified.
Consequently, always stay in control of
your vehicle and be prepared to react at
any time to avoid an accident.

158
Collision Risk Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or
a
pedestrian or cyclist present in your traffic
lane.
The current threshold can be
modified via the Driving /Vehicle
menu of the touch screen.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, several different levels
of alert may be triggered and displayed in the
instrument panel.
They take account of the vehicle dynamics, the
speed of your vehicle and the one in front, the
environmental conditions and the operation of
the vehicle (cornering, actions on the pedals,
etc.) to trigger the alert at the best moment.
Level 1 (orange) : visual alert only,
signalling to you that the vehicle in
front is very close.
The " Vehicle close " message is
displayed.
Level 2 (red) : visual and audible
alert, warning you that a
collision is
imminent.
The message " Brake!" is displayed.
Level 3 : finally, in some cases, a
haptic alert in the form of micro-
braking can be given, confirming the
risk of collision. Where the speed of your vehicle is too
high when approaching another vehicle,
the level 2
alert may be displayed
immediately.
Important: the level 1
alert is never
displayed for a
stationary obstacle or
when the " Close" trigger threshold has
been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid
a collision, this system will supplement the
braking, within the limits of the laws of physics.
This assistance will only be provided if you
press the brake pedal.
After an impact, the function automatically
stops operating. Contact a

CITROËN
dealer or a

qualified workshop to have the
system checked.

159
Active Safety Brake
Operation
- The vehicle's speed does not exceed 50 mph (80 km/h) when a stationary vehicle
or a
cyclist is detected.
-

T
he vehicle's speed is above 6 mph
(10
km/h) (versions with camera and radar)
or between 6
mph and 53 mph (10 km/h and
85
km/h) (versions with camera alone) when
a
moving vehicle is detected.If the camera and/or radar have
confirmed the presence of a
vehicle,
a pedestrian or a
cyclist, this
warning lamp flashes (for about
10
seconds) when the function is
acting on the vehicle's brakes.
With an automatic gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, keep the brake
pedal pressed down to prevent the vehicle from
starting off again.
With a
manual gearbox, in the event of
automatic emergency braking until the vehicle
comes to a
complete stop, the engine may stall.
The driver can control the vehicle at any
time by making a
deliberate movement
of the steering wheel and/or pressing the
accelerator pedal. Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a
complete stop,
the automatic braking is maintained for
1
to 2 seconds.
Malfunction
In the event of a fault with the
s ystem, you are alerted by the
continuous illumination of this
warning lamp, accompanied by the
display of a
message and an audible
signal.
Contact a
CITROËN dealer or
a
qualified workshop to have the
system checked.
This function, also called automatic emergency
braking, inter venes following the alert if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid
a

frontal collision by your vehicle where the
driver fails to react.
The system operates under the following
conditions:
-

T

he vehicle's speed does not exceed
37

mph (60

km/h) when a

pedestrian is
detected.
Fatigue detection system
Refer to the General recommendations on
the use of driving and manoeuvring aids .
Take a
break as soon as you feel tired or at
least every two hours.
The function comprises the "Coffee Break
Alert" system combined with the "Driver
Attention Alert" system.
