"Hold the wheel". If, while correcting the trajectory, the system determines that the correction will not be
enough and that a solid line will be crossed: the driver is warned that \
they must provide
additional trajectory adjustment.
If the steering wheel is not held properly, an audible warning sounds, accompanied by
a message, until the trajectory correction is completed or the driver ha\
s grasped the
steering wheel correctly.
The duration of audible warnings will increase if multiple corrections a\
re performed
in quick succession. The warning will become continuous, persisting until the driver
responds.
Operating limits
The system goes into standby automatically in
the following cases:
–

ESC deactivated or operation triggered.
–


Speed below 40 mph (65
km/h) or greater
than 112 mph (180
km/h).
–

Electrical connection to a trailer
.
–

Use of a"space-saver" spare wheel detected
(as detection is not immediate, deactivation of
the system is recommended).
–


Dynamic driving style detected, pressure on
the brake or accelerator pedal.
–


Driving over lane markings.
–


Activation
of the direction indicators.
–

Crossing the inside line on a bend.
–


Driving on a tight bend.
–


Inactivity by the driver detected during
correction.
–


Narrow lane detected.
The following situations may interfere with the operation of the system or
prevent it from working:
–

Insufficient contrast between the road
surface and the side of the road (e.g. shade).
–


Lane markings worn, hidden (snow
, mud)
or multiple (roadworks, etc.),
–

Close proximity to the vehicle in front (lane
markings may not be detected).
–


Roads that are narrow
, winding.
Risk of undesirable operation
The system should be deactivated in the
following situations:
–
When changing a wheel or working near a
wheel.
–


T
owing or with a bicycle carrier on a towing
device, especially with trailer not plugged in or
not approved. –

Road in poor condition, unstable or with very
poor grip (risk of aquaplaning, snow
, ice).
–
Adverse weather conditions.
–

Driving on racing circuits.
–

Driving on a rolling road.
Deactivation/Activation

Driving

The vehicle has a multifunction camera located
at the top of the windscreen and, depending on
version, a radar located in the front bumper.
This system does not replace the need for vigilance on the part of the driver.
This system is designed to assist the driver
and improve road safety.
It is the driver's responsibility to continuously
monitor traffic conditions in accordance with
applicable driving regulations.
As soon as the system detects a potential obstacle, it prepares the braking
circuit in case automatic braking is needed.
This may cause a slight noise and a slight
sensation of deceleration.
Deactivation/Activation
By default, the system is automatically activated
at every engine start.
The settings are changed via the Driving/Vehicle touch screen menu.
Deactivation of the system is signalled by
the illumination of this warning lamp,
accompanied by the display of a message.
Operating conditions and
limits
Vehicle moving forward.
ESC system operational.
Seat belts fastened for all passengers.
Stabilised speed on roads with few bends.
In the following cases, deactivating the system
via the vehicle's configuration menu is advised:
–

T
owing a trailer.
–

Carrying long objects on roof bars.
–


V
ehicle with snow chains fitted.
–

Before using an automatic car wash, with the
engine running.
–


Before placing the vehicle on a rolling road in
a workshop.
–


T
owed vehicle, engine running.
–

Following
an impact to the windscreen close to
the detection camera.
The system is automatically deactivated when the use of certain types of
"space-saver" spare wheel (smaller diameter)
is detected, or if a fault with the brake pedal
switch or at least two brake lamps is detected.
It can be dangerous to drive if the brake
lamps are not in perfect working order.
It is possible that warnings are not given,
are given too late or seem unjustified.
The driver must always stay in control of the
vehicle and be prepared to react at any time
to avoid an accident.
Following an impact, the system is
automatically deactivated.
Have it checked by a CITROËN dealer or a
qualified workshop.
Collision Risk Alert
This function warns the driver that their vehicle
is at risk of a collision with the vehicle in front, or
with a pedestrian or cyclist present in their traffic
lane.
Modifying the alert trigger threshold
This trigger threshold determines the sensitivity
with which the function warns of the risk of
collision.
The threshold is set via theDriving/Vehicle touch screen menu.
►

Select one of the three pre-defined
thresholds: "Far", "Normal" or "Close".
The last threshold selected is memorised when
the ignition is switched off.
Operation
Depending on the degree of risk of collision
detected by the system and the alert trigger
threshold chosen by the driver, several different

125
Driving
6The driver can maintain control of the vehicle at any time by firmly turning the
steering wheel and/or firmly depressing the
accelerator pedal.
The brake pedal may vibrate slightly while the function is operating.
If the vehicle comes to a complete stop,
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message and
an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
These warning lamps light up on the instrument panel to indicate
that the driver's and/or front passenger's seat
belt is not fastened (depending on version). The
automatic braking system is deactivated until the
seat belts are fastened.
Distraction detection
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
Depending on version, the function consists of
either the "Coffee Break Alert" system alone or
combined with the "Driver Attention Warning"
system.
These systems are in no way designed to keep the driver awake or to prevent
the driver from falling asleep at the wheel.
It is the driver’s responsibility to stop if feeling
tired.
Take a break if you are feeling tired or at least
every 2 hours.
Activation/Deactivation
This function is set via the touch screen Driving/Vehicle menu.
The function is activated by default when the
ignition is switched on.
Coffee Break Alert
The system triggers an alert when it detects that the driver has not taken a
break after two hours of driving at a speed above
43 mph (70
km/h).
This alert is issued via the display of a message
encouraging the driver 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:
–

With the engine running, the vehicle has been
stationary for more than 15 minutes.
–


The ignition has been switched off for a few
minutes.
–


The driver's seat belt is unfastened and their
door is opened.
As soon as the speed of the vehicle drops below 43 mph (70 km/h), the
system goes into standby.
Driving time starts being counted again once
the speed reaches above 43
mph (70 km/h).
Driver Attention Warning
Depending on version, the Coffee Break Alert
system may be combined with the Driver
Attention Warning system.

172
In the event of a breakdown
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
Light-emitting diode (LED)

Depending on version, the affected types of
headlamps/lamps are:
–

"LED" technology headlamps.
–


Front foglamps.
–
