Driving
6first 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 "Near" 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 the driver
presses 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 subject to 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 or a cyclist
is detected.
– The 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 only) when a moving
vehicle is detected.
This warning lamp flashes (for approximately 10 seconds) as soon as
the function applies the vehicle’s brakes.
With an automatic gearbox, in the event of
automatic emergency braking bringing the
vehicle to a complete stop, keep the brake
pedal pressed down to prevent the vehicle from
moving off again.
With a manual gearbox, in the event of automatic
emergency braking bringing the vehicle to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may vibrate slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Malfunction
A fault in the system is signalled by the fixed illumination of this warning lamp,

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.

138

"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.

Blind Spot Monitoring
Refer to the General recommendations on the
use of driving and manoeuvring aids .


This system includes sensors, placed on the
sides of the bumpers, and warns the driver of
the potentially dangerous presence of another
vehicle (car, truck, motorcycle) in the blind spot
areas of their vehicle (areas hidden
from the
driver's field of vision).


The warning is given by a fixed warning lamp
that appears in the door mirror on the side in
question:
–

immediately
, when being overtaken;
–

after a delay of about one second, when
overtaking a vehicle slowly

.
Activation/Deactivation

.
–

In very heavy traffic: vehicles detected in
front and behind are confused with a lorry or a
stationary object.
–


If the Park
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.
For more information on the Active Lane
Departure Warning System and Blind Spot
Monitoring , refer to the corresponding sections.
Parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .

142
Driving
The rear parking sensors system will be deactivated automatically if a trailer or
bicycle carrier is connected to a towing device
installed in accordance with the
manufacturer's recommendations.
In this case, the outline of a trailer is displayed
at the rear of the image of the vehicle.
The parking sensors are deactivated while the
Park Assist function is measuring a space.
For more information on the Park Assist, refer
to the corresponding section.
When the vehicle is started, the visual
and audible aids will be available after
the touch screen has started up.
Operating limits
If the boot is heavily loaded, the vehicle may tilt,
affecting distance measurements.
Malfunction
In the event of a malfunction when
shifting to reverse, one of these
warning lamps comes on on the instrument
panel, accompanied by the display of a message
and an audible signal (short beep).
If the malfunction occurs while the parking
sensors are being used, it causes the function to
deactivate.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.

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
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
and the vehicle (white: more distant, orange:
close, red: very close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing 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).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6
mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, in front or behind it.
Deactivation/Activation
It is set via the Driving/Vehicle touch
screen menu.
The system status is memorised when the
ignition is switched off.
