Assisted Lane Departure Warning System
Using a camera placed at the top of the windscreen to identify lane markings on the ground, this system corrects the trajectory of the vehicle while
alerting the driver if it detects a risk of involuntary crossing of a line.
This system is particularly useful on motor ways and main roads.This system is a driving aid which cannot,
in any circumstances, replace the need
for vigilance on the part of the driver.
The driver remains responsible for the
vehicle in all circumstances. The system
helps the driver only when there is a risk
of the vehicle involuntarily wandering
from the lane it is being driven on. It does
not manage the safe driving distance, the
speed of the vehicle or the brakes.
The driver must hold the steering wheel in
a way that allows control to be taken back
in circumstances where the system is not
able to intervene (where there are no lane
markings, for example).
It is necessary to observe the driving
regulations and take a break every two
hours.
Operation
Conditions for operation
The speed of the vehicle must be between 40
and 112 mph (65 and 180 km/h).
The carriageway must have at least one lane
marking (solid or broken) on the ground.
The driver must hold the wheel with both
hands.
The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated. Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory necessary to return the vehicle to its
initial path.
The driver will then notice a turning movement
of the steering wheel.
This warning lamp flashes during
trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, they 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.

However, with the "Blind Spot Monitoring
System" activated, if the driver starts changing
lane 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.
For more information on the Blind Spot
Monitoring System, 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.
Activation / Deactivation
Activation / deactivation of the system is done
in the Driving
menu of the touch screen.
Select the " Driving functions " tab then
" Lane


assist".
The state of the system stays in memory when
the ignition is switched off.
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.

Blind Spot Monitoring System
Activation / Deactivation
A warning lamp appears in the door mirror on
the side in question:
-
i
mmediately, when being overtaken,
-

a
fter a delay of about one second, when
overtaking a vehicle slowly.
This system warns the driver of the presence of
another vehicle in the blind spot angle of their
vehicle (areas masked from the driver's field
of vision), as soon as this presents a potential
danger. Sensors fitted in the front and rear bumpers
monitor the blind spots.
The state of the system remains in memory on
switching off the ignition.
This system is designed to improve safety when driving and is in no circumstances a
substitute for the use of the interior rear view mirror and door mirrors. It is the driver's
responsibility to constantly check the traffic, to assess the distances and relative speeds of
other vehicles and to predict their movements before deciding whether to change lane.
This system is a driving aid that cannot, in any circumstances, replace the need for
vigilance on the part of the driver. Activation and deactivation of the system is
done in the Driving
menu of the touch screen.
Select the " Driving functions " tab, then
" Blind spot sensors ".
This indicator lamp comes on in the
instrument panel.
To deactivate the system, select " Blind spot
sensors " again in the " Driving functions " tab.
The indicator lamp goes off.
The system is automatically deactivated
when towing with a towbar approved by
CITROËN.

The alert is given by a warning lamp which
comes on in the door mirror on the side in
question as soon as a vehicle - car, lorry,
bicycle - is detected.
The following conditions must be met for this:
-
a
ll vehicles are moving in the same
direction and in adjacent lanes,
-

t
he speed of your vehicle is between 7 and
87 mph (12 and 140 km/h),
-

y
ou overtake a vehicle with a speed
difference of less than 6 mph (10 km/h),
-

a v
ehicle overtakes you with a speed
difference of less than 16 mph (25 km/h),
-

t
he traffic is flowing normally,
-

i
n the case of an overtaking manoeuvre,
if this is prolonged and the vehicle being
overtaken remains in the blind spot,
-

y
ou are driving on a straight or slightly
curved road,
-

y
our vehicle is not pulling a trailer, a
caravan, etc. No alert will be given in the following situations:
-

i
n the presence of non-moving objects
(parked vehicles, barriers, street lamps,
road signs, etc.),
-

w
ith vehicles moving in the opposite
direction,
-

d
riving on a winding road or a sharp corner,
Operation
- when overtaking (or being overtaken by) a very long vehicle (lorry, coach, etc,) which
is at the same time detected at the rear
in the blind spot angle and present in the
driver's for ward field of vision,
-

i
n very heavy traffic: vehicles detected in
front and behind are confused with a lorry
or a stationary object,
-

w
hen overtaking quickly.

In the event of a fault, this warning
lamp flashes for a few moments in
the instrument panel, accompanied
by illumination of the Service warning
lamp and the display of a message.
Operating fault
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 sur face
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 angle is 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 the correct operation
of the system.
High pressure jet wash
When washing your vehicle, direct the
lance at least 30 cm away from the
sensors.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 cross a lane marking
with the direction indicators on, to help you
avoid a collision.
Conditions for operation
The following systems must be activated:
-
B lind Spot Monitoring System,
-

A
ssisted Lane Departure Warning System.
Assisted Blind Spot
Monitoring System*

Monitoring System and the Assisted Lane

Fatigue detection system
It is recommended that you take a break as soon as you feel tired or at least every two hours.
Depending on version, the function either has the "Driving time warning" only, or this combined with the "Fatigue detection system".
Driving time warning
The system triggers an alert once 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 takes the form of the display of a
message encouraging you 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 cannot in any
circumstances replace the need for
vigilance on the part of the driver.
Do not take the wheel if you are tired.
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).
The system resets itself if one of the following
conditions is met:
-

e
ngine running, the vehicle has been
stationary for more than 15 minutes,
-

t
he ignition has been switched off for a
few
m

inutes,
-

t
he driver's seat belt is unfastened and
their door is open.
The system is activated or deactivated in the
touch screen tablet.
Activation / Deactivation
In the Driving
menu, select the " Vehicle
settings " tab, then " Security" and "Fatigue
Detection System ".
