EnglishDriving -> Active Lane Departure Warning System for your Citroen C5 Aircross 2017-2025
Driving
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.
Operation
The following situations may interfere with
the operation of the system or prevent it
from working:
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory required to return the vehicle to its
initial path.
-
poor visibility (inadequate lighting of
the road, falling snow, heavy rain,
dense fog, etc.),
-
dazzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light, etc.),
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
-
-
windscreen area located in front of the
camera: dirty, misted up, frost-covered,
snow-covered, damaged or covered by
a sticker,
lane markings absent, worn, hidden
(snow, mud) or multiple (roadworks,
etc.),
The driver 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.
Conditions for operation
-
-
close to the vehicle ahead (lane
markings not detected),
roads that are narrow, winding, etc.
The speed of the vehicle must be between
40 and 112 mph (65 and 180 km/h).
The driver must hold the wheel with both
hands.
6
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must not be faulty.
The ASR/DSC systems must be activated.
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.
Active Lane Departure
Warning System
Refer to the General recommendations on
the use of driving and manoeuvring aids.
The system helps the driver only when
there is a risk of the vehicle involuntarily
wandering from the lane it is being driven
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.

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.
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
of the vehicle even though the direction
indicators are on.
ON
System active, conditions not met:
-
-
-
speed below 40 mph (65 km/h),
no lane marking recognised,
ASR/DSC systems deactivated
or regulation by ESC system in
progress,
-
"sporty" driving.
ON
Automatic deactivation/standby of the
system (e.g. detection of a trailer, use of
the "space-saver" spare wheel provided
with the vehicle).
For more information on the Blind Spot
Monitoring system, refer to the corresponding

If, during correction, the system
detects that the driver has not held
the steering wheel for a few seconds,
it interrupts the correction and returns
control to the driver.
During correction of the trajectory,

correction will not be enough and
that a solid line is crossed (orange

must complete the correction of the
trajectory.

Driving
The following situations may interfere with
The system is not intended for driving in the
following situations:
Malfunction
the operation of the system or prevent it
from working:
-
-
-
-
driving on a speed circuit,
driving with a trailer,
driving on a rolling stand,
driving on unstable surfaces.
-
conditions of poor visibility (inadequate
street lighting, snowfall, rain, fog),
dazzle (headlamps of an oncoming
vehicle, low sun, reflections on a damp
road, leaving a tunnel, alternating
shade and light),
-
In the event of a fault with the system, you are
alerted by the illumination of these warning
lamps in the instrument panel, accompanied by
the display of a message and an audible signal.
Have the system checked by a CITROËN
dealer or a qualified workshop.
Deactivation/Activation
The system is activated every time the ignition
is switched on.
-
windscreen area located in front of the
camera: dirty, misted, frost-covered,

a sticker,
-
-
lane markings worn, hidden (snow,
mud) or multiple (roadworks, etc.),
