Collision Risk Alert and Active Safety Brake
This system includes three functions:
- C ollision Risk Alert (alert if there is a risk of
collision),
-

I
ntelligent emergency braking assistance,
-

A
ctive Safety Brake (automatic emergency
b r ak ing).
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.
Intelligent emergency braking assistance:
it completes the braking action taken by the
driver if this is inadequate.
Active Safety Brake: it intervenes following
the alert if the driver does not react quickly
enough and does not operate the vehicle's
brakes.
If the driver fails to act, the system
contributes towards avoiding a collision or
limiting its severity by reducing the speed
of your vehicle. 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.
This system does not avoid the need for
vigilance on the part of the driver.
The vehicle is fitted with a radar located in the front bumper and a camera at the top of the
windscreen.
Conditions for activation and operation
The system is active from about 4 mph (7 km/h)
and is deactivated below about 3 mph (5 km/h).
It takes account of:
-

v
ehicles running in the same direction or
stationary,
-

p
edestrians present in the traffic lane
(bicycles, motorcycles, animals and objects
on the road are not necessarily detected).

Assisted Lane Departure Warning System
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this system corrects the trajectory of the vehicle while
alerting the driver if it detects a risk of involuntary crossing of a line.
This system is particularly useful on motor ways and main roads.This system is a driving aid which cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
The driver remains responsible for the
vehicle in all circumstances. The system
helps the driver only when there is a risk
of the vehicle involuntarily wandering
from the lane it is being driven on. It does
not manage the safe driving distance, the
speed of the vehicle or the brakes.
The driver must hold the steering wheel in
a way that allows control to be taken back
in circumstances where the system is not
able to intervene (where there are no lane
markings, for example).
It is necessary to observe the driving
regulations and take a break every two
hours.
Operation
Conditions for operation
The speed of the vehicle must be between 40
and 112 mph (65 and 180 km/h).
The carriageway must have at least one lane
marking (solid or broken) on the ground.
The driver must hold the wheel with both
hands.
The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated. Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory necessary to return the vehicle to its
initial path.
The driver will then notice a turning movement
of the steering wheel.
This warning lamp flashes during
trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, they can
prevent the correction by keeping a firm
grip on the wheel (during an avoiding
manoeuvre, for example).
The correction is interrupted if the
direction indicators are operated.

However, with the "Blind Spot Monitoring
System" activated, if the driver starts changing
lane and another vehicle is detected in the
vehicle's blind spot, the system will correct
the trajectory of the vehicle even though the
direction indicators are on.
For more information on the Blind Spot
Monitoring System, refer to the corresponding
section. If the system detects that the driver is
not holding the wheel firmly enough
during an automatic correction of
trajectory, it interrupts the correction.
An alert is triggered to encourage
the driver to take back control of the
vehicle.
Activation / Deactivation
Activation / deactivation of the system is done
in the Driving
menu of the touch screen.
Select the " Driving functions " tab then
" Lane


assist".
The state of the system stays in memory when
the ignition is switched off.
While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory
is voluntary and no correction is triggered
during this period.

Blind Spot Monitoring System
Activation / Deactivation
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a vehicle slowly.
This system warns the driver of the presence of
another vehicle in the blind spot angle of their
vehicle (areas masked from the driver's field
of vision), as soon as this presents a potential
danger. Sensors fitted in the front and rear bumpers
monitor the blind spots.
The state of the system remains in memory on
switching off the ignition.
This system is designed to improve safety when driving and is in no circumstances a
substitute for the use of the interior rear view mirror and door mirrors. It is the driver's
responsibility to constantly check the traffic, to assess the distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
This system is a driving aid that cannot, in any circumstances, replace the need for
vigilance on the part of the driver. Activation and deactivation of the system is
done in the Driving
menu of the touch screen.
Select the " Driving functions " tab, then
" Blind spot sensors ".
This indicator lamp comes on in the
instrument panel.
To deactivate the system, select " Blind spot
sensors " again in the " Driving functions " tab.
The indicator lamp goes off.
The system is automatically deactivated
when towing with a towbar approved by
CITROËN.

In the event of a fault, this warning
lamp flashes for a few moments in
the instrument panel, accompanied
by illumination of the Service warning
lamp and the display of a message.
Operating fault
Contact a CITROËN dealer or a qualified
workshop to have the system checked.The system may suffer temporary
interference in certain weather
conditions (rain, hail, etc.).
In particular, driving on a wet sur face
or moving from a dry area to a wet area
can cause false alerts (for example, the
presence of a fog of water droplets in
the blind spot angle is interpreted as a
vehicle).
In bad or wintry weather, ensure that
the sensors are not covered by mud, ice
or snow.
Take care not to cover the warning zone
in the door mirrors or the detection
zones on the front and rear bumpers
with adhesive labels or other objects;
they may hamper the correct operation
of the system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.In addition to the fixed warning lamp in the door
mirror on the side in question, a correction of
trajectory will be felt if you cross a lane marking
with the direction indicators on, to help you
avoid a collision.
Conditions for operation
The following systems must be activated:
-
B lind Spot Monitoring System,
-

A
ssisted Lane Departure Warning System.

Front parking sensors
The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.The system will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fitted on
a towbar (vehicle fitted with a towbar
installed in line with the manufacturer's
recommendations).In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.
As an 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 remains below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The parking sensors can be deactivated in the
touch screen.

Reversing camera
Clean the reversing camera regularly
using a soft, dry cloth.
The reversing camera is activated automatically
when reverse gear is engaged.
Depending on version, the image is displayed
in the touch screen or the instrument panel.
The superimposed representation of guide
lines helps with the manoeuvre.The blue lines represent the general direction
of the vehicle (the difference corresponds to
the width of your vehicle without the mirrors).
The red lines represent a distance of about
30 cm beyond the edge of your vehicle's rear
b u m p e r.
The green lines represent distances of
about

1 and 2 metres beyond the edge of your
vehicle's rear bumper.
The turquoise blue curves represent the
maximum turning circle.
The reversing camera cannot in any
circumstances replace the need for
vigilance on the part of the driver. Opening the tailgate causes the display
to disappear.
The reversing camera function may be
supplemented by parking sensors.
High pressure jet washing
When washing your vehicle, do not
direct the lance within 30 cm of the
camera lens. They are represented by lines marked
"on the ground" and do not allow the
position of the vehicle to be determined
relative to tall obstacles (e.g. other
vehicles).
Some deformation of the image is normal.
It is normal to be able to see part of the
number plate at the bottom of the screen.

360 Vision
This system provides a view in the instrument
panel of the near surroundings of your vehicle,
using cameras mounted at the front and rear of
your vehicle and under the door mirrors.
Depending on the angle of view chosen (front
view, rear view or 360° panoramic view),
360 Vision provides special visual assistance
in particular driving conditions such as when
entering a blind junction or manoeuvring in
areas of reduced visibility.
Once activated, this function operates up to
9
mph (15 km/h). Above 18 mph (30 km/h), the
function is deactivated automatically. This system is a visual aid which in no
circumstances can replace the need for
vigilance on the part of the driver.
The images provided by the cameras
may be deformed by the relief. The
presence of areas in shade, in sunny
conditions, or of low ambient light may
darken the image and reduce contrast.Forward vision
The camera located in the front bumper is
activated and views of the areas located at
front left and front right appear simultaneously
in the instrument panel.
Rear vision
The camera located in the tailgate is activated
and the view of the area behind your vehicle is
displayed in the instrument panel and behaves
like a reversing camera, whatever the position
of the gear selector lever.
The blue lines represent the width of your
vehicle (excluding mirrors): they move
according to the position of the steering wheel.
The red line represents a distance of 30 cm
from the rear bumper, and the two green
lines, 1 m and 2 m from the rear bumper,
respectively.
Rear vision is displayed automatically
when engaging reverse, regardless of
the state of the system.
