– 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).
–


Front end of the vehicle modified (for
example by adding long-range headlamps or
painting the front bumper).
–


Obstructed radar and/or camera.
Malfunction
In the event of a malfunction,
dashes are displayed instead of
the speed setting.
This warning lamp comes on, accompanied by a message and an
audible signal, to confirm the malfunction.
Have it checked by a CITROËN dealer or a
qualified workshop.
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)

124
Driving
All operating conditions are met; the system is
active.
(orange)
System malfunction.
If the driver no longer wishes to use the system
for some time, they can deactivate it by pressing
the button again (confirmed when the symbol
disappears).
The system status is saved when the ignition is switched off.
Operating conditions
– Adaptive cruise control active.
– ESC system operational.
–

ASR system activated.
–


No trailer detected.
–


No 'space-saver' spare wheel in use.
–


V
ehicle not subject to strong lateral g-forces.
–

Direction indicators not activated.
Regulation
The driver must hold the steering wheel
properly.
When regulation is activated, the symbols are
displayed in green: with small steering inputs,
the system steers the vehicle and keeps it in the
position chosen by the driver in the traffic lane.
This position is not necessarily the centre of the
lane.
The driver can feel movements in the steering
wheel.
At any time, the driver can change the position of
the vehicle by intervening on the steering wheel
and maintaining the position until the system has
taken it into account. If the chosen position is too
off-centre, an automatic re-centering manoeuvre
can occur. The system adjusts to the newly
defined position.
Pausing/Suspending the
system
The driver must act promptly if they believe that the traffic conditions or the
state of the road surface require their
intervention, by moving the steering wheel to
temporarily suspend system operation. Any
action on the brake pedal that causes the
Adaptive cruise control
system to be paused
will also cause the system to be paused.
If the system detects that the driver is not
holding the wheel firmly enough, it
triggers a series of gradual alerts and then
deactivates itself if there is no response from
the driver.
If the function is suspended due to the
prolonged release of the force holding
the steering wheel, the system must be
reactivated by pressing the button again.
Automatic suspension
Suspension of the system is accompanied by a
specific audible signal.
–

T
riggering of the ESC system.
–

Insufficient lane detection. In this case, the
Lane keeping assist function can take over

,
and the system will reactivate itself once the
operating conditions are met again.
Paused by the driver
– Travelling outside the lane limits.
– T oo tight a grip on the steering wheel or
dynamic action on the steering wheel.
–

Action on the brake pedal (resulting in a pause
until cruise control is reactivated) or accelerator
pedal (suspension for as long as the pedal is
depressed).
–


Pausing of the
Adaptive cruise control system.
–

Deactivation of the
ASR system.

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).
–

In roadworks or toll booth areas.
–


Driving on racing circuits.
–


Driving on a rolling road.
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

129
Driving
6correction necessary to restore the vehicle to its
original lane.
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 firmly holding the steering wheel
(e.g.
during an emergency manoeuvre).
The correction is interrupted immediately if
the direction indicators are operated. While the direction indicators are activated and
for a few seconds after switching them off, the
system considers that a change of trajectory is
intentional and no correction is triggered during
this period.
Driving situations and related alerts
The table below describes the alerts and messages displayed in different driving situations.
The actual order of display of these alerts may be different.
