– When a vehicle cuts in sharply between your
vehicle and the one in front.
Some vehicles on the road may be
poorly perceived or interpreted by the
camera and/or the radar (e.g.
truck), which
can lead to an incorrect evaluation of
distances and result in inappropriate
acceleration or braking of the vehicle.
Pay particular attention:
– When motorcycles are present and
when there are vehicles staggered across the
traffic lane.
–

When entering a tunnel or crossing a
bridge.
If any of the following malfunctions
occurs, do not use the system:
–

Following an impact on the windscreen
close to the camera or on the front bumper
(versions with radar).
–


Brake lamps not working.
If the vehicle has undergone any of the
following modifications, do not use the
system:
–

Carrying long objects on roof bars.
–


Towing.
–

Use of the "space-saver" type spare wheel
(depending on version).
–

Lane positioning assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .


The system identifies the edges of the traffic lane
and steers the vehicle to keep it inside this lane
and maintain the lateral position chosen by the
driver.
To do this, the system uses a camera placed on
the upper part of the windscreen.
This system is particularly suited to driving on
motorways and main roads.
Activation/Deactivation
The Lane positioning assist system is
automatically activated, after selecting Highway
Driver Assist mode.
For more information on the Highway Driver
Assist system, refer to the corresponding
section.
The selection is confirmed by the display of
the symbols on the instrument panel or on the
head-up display (if fitted), representing the
steering wheel and the side lines.
The colour of the symbols depends on the
operating state of the system:
(grey)
One or more operating conditions is not
met; the system is paused.
(green)

Operating limits
The system may issue an alert when the vehicle is travelling on a long, straight
road with smooth road surface even if the
driver thinks they are holding the steering
wheel correctly.
The system may not operate or may produce
unsuitable corrections to the steering in the
following situations:
–

Poor visibility (insufficient road lighting,
snowfall, rain, fog).
–


Dazzle (headlamps of an oncoming vehicle,
low sun, reflections on a wet road surface,
leaving a tunnel, alternating light and shade).
–


Windscreen area in front of the camera
dirty

, misted up, frost-covered, snow-covered,
damaged or covered by a sticker.
–

Lane markings eroded, partially hidden (snow
,
mud) or multiple (roadworks, surface joints).
–

T

ravelling in a tight bend.
–

Winding roads.
–


Presence of a tarmac joint on the road.
Risk of undesirable operation
The system should be deactivated in the following situations:
–

Driving with a "space-saver" type spare
wheel.
–


When towing or with a bicycle carrier
attached to a towing device, particularly when
a trailer is not connected or the trailer is not
an approved type.
–

Adverse weather conditions.
–


Driving on slippery road surfaces (risk of
aquaplaning, snow

, ice).
–

Malfunction
In the event of a malfunction, the
Service warning lamp comes on
and this (orange) symbol appears on the
instrument panel, accompanied by the display of
a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Lane keeping assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.


Operating conditions
– Vehicle speed between 40 and 112 mph (65
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 braking.
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
As soon as the system identifies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g.
grass verge), it performs the trajectory

"Hold the steering
wheel" or "Stay in lane" (depending on version) If, while correcting the trajectory, the system determines that the correction will not be
enough and that a solid line will be crossed: the driver is warned that \
they must provide
additional trajectory adjustment.
If the steering wheel is not held properly, an audible warning sounds, accompanied by
a message, until the trajectory correction is completed or the driver ha\
s grasped the
steering wheel correctly.
The duration of audible warnings will increase if multiple corrections a\
re performed
in quick succession. The warning will become continuous, persisting until the driver
responds.
Operating limits
The system goes into standby automatically in
the following cases:
–

ESC deactivated or operation triggered.
–

Collision Risk Alert
This function warns the driver if there is a risk
of collision with the preceding vehicle, or with a
pedestrian or cyclist.
Modifying the alert trigger threshold
The trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The selected threshold is memorised when the
ignition is switched off.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The threshold is set via the Driving touch screen menu.
►

Select one of the three pre-defined
thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive
The threshold is set via the Vehicle touch screen menu.
►

thresholds: "

Far", "Normal" or "Close".
With MyCitroën Drive Plus
The threshold is set via the ADAS touch screen application.
► Select one of the 3 preset thresholds: " Far ",
"Medium" or "Near".
Operation
Depending on the collision risk detected by the
system and the alert trigger threshold chosen
by the driver, different levels of alert may be
triggered and displayed on the instrument panel.
The system takes into account the vehicle
dynamics, the difference speed of the own
vehicle and the object identified for the
collision risk, and the operation of the vehicle
(e.g.
actions on the pedals, steering wheel) to
trigger the alert at the most relevant moment.
(orange)
Level 1: visual alert only, warning that the
preceding vehicle is very close.
The message "Vehicle close" is displayed.
(red)
Level 2: visual and audible alert, warning
that a collision is imminent.
The message "Brake! " is displayed.
Level 3: a micro-braking may be given,
confirming the risk of collision (optional).
While approaching a vehicle too quickly,
the level 2 alert may be displayed
directly.
Important: the level 1 alert depends on the
trigger threshold selected. It reacts only on
moving vehicles. It is disabled automatically
at lower speed.

Driving
Adjusting the audible signal
(With MyCitroën Drive or MyCitroën
Drive Plus)
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 that represent 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 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.
Side parking sensors

Using four additional sensors located on the
sides of the bumpers, the system records the
position of obstacles during the manoeuvre and
indicates them when they are located alongside
the vehicle.
Only fixed obstacles are indicated
correctly. Moving obstacles detected at
the beginning of the manoeuvre may be
indicated mistakenly, while moving obstacles
that appear alongside the vehicle but were
not previously recorded will not be indicated.
Objects memorised during the
manoeuvre will no longer be stored after
switching off the ignition.
