Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
On versions with camera alone, this message
indicates to you that the camera is obstructed:
"Driving aids camera: visibility limited, see
user guide".
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
During parking manoeuvres, STOP mode
is not available for a few seconds after

Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climactic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
check the traffic, to assess the relative
distances and speeds of other vehicles and to
anticipate their movements before indicating
and changing lane.
The systems cannot exceed the limits of the
laws of physics.
Driving aids
You should hold the steering wheel
with both hands, always use the interior and
exterior rear view mirrors, always keep the
feet close to the pedals and take a break
every two hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;

Driving
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is not displayed
when there is a stationary obstacle or when
the "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This threshold determines how you wish to be
warned of the presence of a moving or stationary
vehicle in front of you, or a pedestrian present in
your traffic lane.
The current threshold can be modified via the
vehicle configuration menu.
You can select one of three pre-defined
thresholds:
– "Distant",
– "Normal",
– "Close".
The last threshold selected is memorised when
the ignition is switched off.
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.
– warns the driver that their vehicle is at risk of
collision with the vehicle in front or a pedestrian.
–

reduces the vehicle's speed to avoid a
collision or limit its severity

.
This system is comprised of three functions:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a camera located at the top of
the windscreen.
This system does not avoid the need for vigilance on the part of the driver.
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.
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.
Operating conditions and
limits
The ESC system must not be faulty.
The ASR system 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:
–

towing a trailer
,
–

carrying long objects on roof bars or roof rack,
–


with snow chains fitted,
–


before using an automatic car wash, with the
engine running,
–


before placing the vehicle on a rolling road in
a workshop,
–


towed vehicle, engine running,
–


Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated after the use of the "space-saver" type
spare wheel is detected, or if a fault with the
lateral brake lamps is detected.
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.
After an impact, the function automatically stops operating. Contact a
CITROËN dealer or a qualified workshop to
have the system checked.
Collision Risk Alert
It warns the driver that their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different
levels of alert may be triggered and displayed on
the touch screen.
The system takes account of the vehicle
dynamics, the speed of your vehicle and the one
in front, the environmental conditions and the
operation of the vehicle (actions on the pedals,
the steering wheel, etc.) to trigger the alert at the
best moment.
Level 1 (orange): visual alert only,
indicating that the vehicle in front is very
close.
The message
"Vehicle close" is displayed.
Level 2 (red): visual and audible alert,
indicating that a collision is imminent.
The message "Brake! " is displayed.
Level 3: in some cases, a vibration alert in the
form of micro-braking can be given, confirming
the risk of collision.

the "Close" trigger threshold has been
selected.
Modifying the alert trigger threshold
This threshold determines how you wish to be

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.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts 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
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
–

The vehicle's speed does not exceed 37 mph
(60 km/h) when a pedestrian is detected.
–


The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function acts on the vehicle’s braking.
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 maintain control of the vehicle at any time by sharply turning the
steering wheel and/or sharply 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.
Deactivation / Activation
By default, the system is automatically activated
at every engine start.
It is set via the Driving / Vehicle touch
screen menu.

6or other objects; they may hamper correct
operation of the system.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids.


Using sensors located in the bumper, this
system signals the proximity of obstacles
(e.g.
pedestrian, vehicle, tree, barrier) present in
their field of detection.
Rear parking sensors
The system is switched on by engaging reverse
gear, which is confirmed by an audible signal.
The system is switched off when disengaging
reverse gear.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalWith CITROËN Connect Radio or
CITROËN Connect Nav, pressing
this button opens the window for adjusting the
volume of the audible signal.
Visual assistance

It supplements the audible assistance, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant obstacles, orange: close
obstacles, red: very close obstacles).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
In addition to the rear parking sensors, the front
parking sensors are triggered when an obstacle
is detected in front and the speed of the vehicle
is still below 6 mph (10
km/h).
