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:
–
warns the driver that their vehicle is at risk of
collision with the vehicle in front, a pedestrian or
,
depending on version, a cyclist.
–

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

.
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:
–

Collision
Risk Alert.
–

Intelligent emergency braking assistance.
–


Active Safety Brake (automatic emergency
braking).


The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not replace 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 traffic conditions in accordance with
applicable driving regulations.

136
Driving
The following situations may interfere with the operation of the system or
prevent it from working:
– lane markings absent, worn, hidden (snow,
mud) or multiple (roadworks);
– close to the vehicle ahead (lane markings
not detected);
– roads that are narrow, winding, etc.
Active Lane Departure
Warning System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Using a camera located at the top of the
windscreen to identify lane markings on the road
and at the edges of the road (depending on
version), the system corrects the trajectory of the
vehicle while alerting the driver if it detects a risk
of unintentionally crossing a line or hard shoulder
(depending on version).
This system is particularly useful on motorways
and main roads.


accompanied by the display of a message and
an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
These warning lamps come on if the driver's seat belt and/or front
passenger seat belt (depending on version) are
not fastened.
Distraction detection
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Take a break if you are feeling tired or at least
every 2 hours.
The function consists of the "Coffee Break Alert"
system combined with the "Driver Attention
Warning" system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Activation/Deactivation
This function is set via the touch screen Driving/Vehicle menu.
The state of the system is memorised when the
ignition is switched off.
Coffee Break Alert
The system triggers an alert as soon as it detects that the driver has not taken a
break after two hours of driving at a speed above
40 mph (65
km/h).
This alert is issued via the display of a message
encouraging the driver to take a break,
accompanied by an audible signal.
If the driver does not follow this advice, the alert
is repeated hourly until the vehicle is stopped.
The system resets itself if one of the following
conditions is met:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 40 mph (65 km/h), the
system goes into standby.
The driving time is counted again once the
speed is above 40 mph (65
km/h).
Driver Attention Warning

Using a camera placed at the top of the
windscreen, the system assesses the
driver's level of vigilance, fatigue or distraction by
identifying variations in trajectory compared to
the lane markings.
This system is particularly suited to fast roads
(speed higher than 40 mph (65
km/h)).
At a first-level alert, the driver is warned by the
“Take care! ” message, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Dangerous
driving: take a break", accompanied by a more
pronounced audible signal.
In certain driving conditions (poor road
surface or strong winds), the system may
give alerts independent of the driver's level of
vigilance.

137
Driving
6The following situations may interfere with the operation of the system or
prevent it from working:
–

lane markings absent, worn, hidden (snow
,
mud) or multiple (roadworks);
–

close to the vehicle ahead (lane markings
not detected);
–


roads that are narrow
, winding, etc.
Active Lane Departure Warning System
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Using a camera located at the top of the
windscreen to identify lane markings on the road
and at the edges of the road (depending on
version), the system corrects the trajectory of the
vehicle while alerting the driver if it detects a risk
of unintentionally crossing a line or hard shoulder
(depending on version).
This system is particularly useful on motorways
and main roads.


Conditions for operation
– Vehicle speed between 43 and 112 mph (70
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
–


Direction indicators not activated.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or brakes.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the necessary trajectory
correction to return the vehicle to its initial path.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during trajectory correction.
The driver can prevent the correction by keeping a firm grip on the wheel (during
an avoiding manoeuvre, for example).
The correction is interrupted immediately if
the direction indicators are operated.


While the direction indicators are on and for
a few seconds after switching them off, the
system considers that any change of trajectory is
intentional and no correction is triggered during
this period.
However, with the Blind Spot Monitoring system
activated, if the driver starts changing lanes and
another vehicle is detected in the vehicle's blind
spot, the system will correct the trajectory even
though the direction indicators are on.
For more information on the Blind Spot
Monitoring , 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.

"Take control of the vehicle." –

If, while correcting the trajectory
, the system detects
that the driver has not held the steering wheel for a few
seconds, it stops correcting and returns control to the
driver.
– If, while correcting the trajectory , the system determines
that the correction will not be enough and that a solid line
will be crossed (orange line): the driver is warned that they
must provide additional trajectory adjustment.
The duration of audible warnings will increase if multiple
corrections are performed in quick succession. The
warning will become continuous, persisting until the driver
responds.
This message may also be displayed if you have your
hands on the steering wheel.
Operating limits
The system goes into standby automatically in
the following cases:
–

ESC deactivated or operation triggered.
–


Speed below 43 mph (70
km/h) or greater
than 112 mph (180
km/h),
–

Electrical connection of a trailer
.
–

Use of a"space-saver" spare wheel detected
(as detection is not immediate, deactivation of
the system is recommended).
–


Dynamic driving style detected, pressure on
the brake or accelerator pedal.
–


Driving where there are no lane markings.
–


Activation of the direction indicators.
– Crossing the inside line on a bend.
– Driving in a tight corner .
–

Inactivity by the driver detected during
correction.
The following situations may interfere with the operation of the system or
prevent it from working:
–

Insufficient contrast between the road
surface and the side of the road (e.g. shade).
–


Lane markings worn, hidden (snow
, mud)
or multiple (roadworks, etc.),
–

Assist function is activated.
Malfunction
If the event of a malfunction, this warning
lamp comes on in the instrument panel,
accompanied by the display of a message.
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 surface 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 can
be 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
correct operation of the system.
Active Blind Spot Monitoring System
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 attempt to cross
a lane marking with the direction indicator
activated, to help you avoid a collision.
This system is the combination of the Active
Lane Departure Warning System and Blind Spot
Monitoring.
These two functions must be activated and in
operation.
The speed of the vehicle must be between 40
and 87
mph (65 and 140 km/h).
These functions are especially suitable for
driving on motorways and main roads.

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
within the sensors’ detection zone.
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 signalDepending on version, with
CITROËN Connect Radio or
CITROËN Connect Nav, pressing this button
opens the window for adjusting the volume of
the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen whose location
represents the distance between the obstacle
and the vehicle (white: more distant, orange:
close, red: very close).
This supplements the audible signal by
displaying bars on the screen whose location
represents the distance between the obstacle
