night, in fog or moderate rainfall.
However, it is strongly recommended
that you always adapt your speed and
your safety distance from vehicles ahead
according to the driving conditions, the
weather and the road surface.
Use the cruise control only where
the driving conditions allow running
at a
constant speed and keeping an
adequate safety distance.
Do not activate the cruise control in urban
areas where pedestrians are likely to
cross the road, in heavy traffic, on winding
or steep roads, on slippery or flooded
roads, when there is snowfall, if the front
bumper is damaged or when the brake
lamps have failed.

Malfunction
If the cruise control
malfunctions, dashes are
displayed instead of the
cruise control speed setting.
If this warning lamp comes
on, accompanied by an
alert message and an
audible signal, this confirms
a


malfunction.
The adaptive cruise control deactivates
automatically if the use of a "space-saver"
type spare wheel is detected or if there is
a

malfunction on the lateral brake lamps or
trailer brake lamps (for approved trailers).
The following situations may interfere with
the operation of the system or prevent it
from working:
-

Collision Risk Alert
It warns the driver if their vehicle is at risk of
collision with the vehicle in front or a pedestrian
present in their traffic lane.
Modifying the alert trigger
threshold
This threshold determines how you wish
to be alerted of the presence of a moving
or stationary vehicle in front of you, or
a
pedestrian present in your traffic lane.
The current threshold can only be
modified via the touch screen's
Driving menu.
You can select one of three predefined
thresholds:
-
"Distant ",
-
"Normal ",
-
"Close ".
The last threshold selected is kept in memory
when the ignition is switched off.
Operation
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.
Clean the windscreen regularly,
particularly the area in front of the camera.
The internal sur face of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.
Do not allow snow to accumulate on the
bonnet or roof of the vehicle as this could
conceal the detection camera.
Clean the front bumper, especially around
the radar, removing mud, snow, etc.

Driving

169
The driver can maintain control of the
vehicle at any time by sharply turning
the steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for
1
to 2 seconds.
Malfunction
In the event of a fault with the
s ystem, you are alerted by the
illumination of this warning lamp,
accompanied by the display of
a


message and an audible signal.
Lane Departure Warning
System
Using a camera located at the top of the
w indscreen to identify lane markings on the
ground, the 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.
Conditions for operation
The speed of the vehicle must be between
40 mph and 112 mph (65 km/h and 180 km/h).
The driver must hold the steering wheel with
both hands.
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must be activated and fault-
free. This system is a
driving aid that cannot,
in any circumstances, replace the
driver's own vigilance. The driver must
remain in control of the vehicle under 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
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
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 inter vene
(if lane markings disappear, for example).
It is necessary to obser ve the driving
regulations and take a break every two
hours.Operation
Once the system identifies a risk of the vehicle
i nvoluntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory required to return the vehicle to its
initial path.
The driver will notice a
turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
Contact a

CITROËN dealer or a

qualified
workshop to have the system checked.
6
Driving

170
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.
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 Detection 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.
For more information on the Blind Spot
Detection , 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.
Driving situations and
associated alerts
To benefit from all necessary information on
the instrument panel, you must previously
select the "DRIVING" display mode.
The table below describes the alerts and

Active Blind Spot
Monitoring System
(depending on version)
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 Detection,
-
L

ane Departure Warning System.
The speed of the vehicle must be between
40
and 87 mph (65 and 140 km/h) inclusive.
Fatigue detection system
Take a break as soon as you feel tired or at
l east every two hours.
Depending on version, the function relies either
on the "Driver Attention Warning" system alone
or combined with the "Driver Attention Alert"
system.
These systems cannot in any circumstances
replace the need for vigilance on the part
of the driver who must remain in control
of their decisions. In no case can these
systems keep the driver awake or prevent
them from falling asleep at the wheel.
It is the driver's responsibility to stop if they
feel tired.
Activation/Deactivation
These functions are activated and
deactivated in the Driving menu of
the touch screen.
The state of the system stays in the memory
when the ignition is switched off.
Driver Attention 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 is issued via 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 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
minutes,
-
t
he driver's seat belt is unfastened and their
door is open.
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).
Driver Attention Alert
Depending on version, the "Driver Attention
Warning" may be combined with the "Driver
Attention Alert".
