Limits of operation
In the following cases, it is recommended
that the system be deactivated in the vehicle
configuration menu:
-
w
hen towing a trailer or caravan,
-

w
hen carrying long objects on roof bars or
a roof rack,
-

b
efore using an automatic car wash, with
the engine running,
-

b
efore placing the vehicle on a rolling road
in a workshop,
-

w
hen the vehicle is being towed, with the
engine running,
-

w
hen a "space-saver" type spare wheel is
fitted (depending on version),
-

f
ollowing impact damage to the windscreen
close to the detection camera,
-

i
f the front bumper has been damaged,
-

i
f the brake lamps are not working.Because of limits in the operation of the
system, it is possible that warnings are
not given, are given too late or seem
unjustified.
Consequently, the driver must always
remain attentive and able to react at any
time to avoid an accident. Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed:
the level 2 alert may be displayed
di r e c t l y.
Important
: the level 1 alert is never
displayed if the " Close" threshold has
been selected.
Collision Risk Alert
Depending on the degree of risk of collision
detected by the system and the alert threshold
chosen by the driver, different levels of alert can be
triggered and displayed in the instrument panel.
Level 1: visual alert only, signalling
to you that the vehicle in front is very
close.
The message " Vehicle close" is
displayed.
This level of alert is based on the inter-vehicle
time between your vehicle and the vehicle in
front.
Level 2: visual and audible alert,
warning you that a collision is
imminent.
The message " Brake!" is displayed.
This level of alert is based on the time before
collision. It takes account of the vehicle
dynamics, the speed of your vehicle and the
one in front, the environmental conditions, the
operation of the vehicle (cornering, pedals
pressed, etc.) to trigger the alert at the best
moment.
Modifying the alert trigger
threshold
This threshold determines how you wish to be
warned of the presence of a vehicle moving
or stationary in front of you, or a pedestrian
present in your traffic lane.
The current threshold can be modified only via
the Driving menu in the touch screen.
You can select one of three thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.

the bonnet or roof of the vehicle as this
could mask the camera's view.
Clean the front bumper, removing mud,
snow, ... There may be inter ference in the
operation of the camera or it may not
work at all in the following situations:
-

p
oor visibility (inadequate street
lighting, falling snow, heavy rain,
dense fog, ...),
-

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.

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
