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.

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.

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),
-

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

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

Fatigue detection system
Depending on version, the "Driving time
warning" may be combined with the "Fatigue
detection system".
Using a camera placed at the top of the
windscreen, the system assesses the driver's
level of vigilance 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)).Once the system considers that the behaviour
of the vehicle suggests a certain level of fatigue
or inattention by the driver, it triggers the first
level of alert.
The driver is then alerted by the message
"
Ta k e c a r e ! ", accompanied by an audible
signal.
After three first level alerts, the system triggers
a new alert with the message " Take a break!",
accompanied by a more pronounced audible
signal. In certain driving conditions (poor road
sur face or strong winds), the system
may give alerts independent of the
driver's level of vigilance.
The following situations may inter fere
with the operation of the system or
prevent it working:
-
p
oor visibility (inadequate lighting
of the roadway, falling snow, heavy
rain, dense fog, ...),
- d azzle (headlamps of an oncoming
vehicle, low sun, reflections on
a damp road, leaving a tunnel,
alternating shade and light, ...),
-

w

of the camera: dirty, misted, frost-
covered, snow-covered, damaged
or covered by a sticker,
-

Front parking sensors
The sound emitted by the speaker (front
or rear) indicates whether the obstacle
is in front or behind.The system will be deactivated
automatically if a trailer is being
towed or a bicycle carrier is fitted on
a towbar (vehicle fitted with a towbar
installed in line with the manufacturer's
recommendations).In bad weather or in winter, ensure
that the sensors are not covered with
mud, ice or snow. When reverse gear is
engaged, an audible signal (long beep)
indicates that the sensors may be dirty.
Certain sound sources (motorcycle,
lorry, pneumatic drill, etc.) may trigger
the audible signals of the parking
sensor system.
As an addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle remains below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The parking sensors can be deactivated in the
touch screen.
