Cruise control - Specific
recommendations
The cruise control function does not guarantee compliance with the maximum
authorised speed and the safety distance
between vehicles, the driver remains
responsible for their driving.
In the interest of public safety, only use cruise
control if the traffic conditions enable vehicles
to drive at a steady speed and maintain an
adequate safety distance.
Remain vigilant while cruise control is
activated. If you press and hold one of the
speed setting modification buttons, your
vehicle may change speed very abruptly.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the vehicle speed.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
–

In an urban area with the risk of
pedestrians crossing the road.
–


In heavy traffic (except versions with the
Stop & Go function).
–


On winding or steep roads.
–


On slippery or flooded roads.
–


In poor weather conditions.
–


In the event of restricted visibility for the
driver

.
–

Driving on a speed circuit.
–


Driving on a rolling road.
–

–

When using snow chains, non-slip covers
or studded tyres.
Cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and
to

Cruise control - particular
recommendations.
This system automatically maintains the vehicle’s speed at the value programmed
by the driver (speed setting), without the use of
the accelerator pedal.
Cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40

km/h).
With an automatic gearbox, mode

D
or second
gear or higher in mode

M
must be engaged.
Cruise control remains active after
changing gear on engines fitted with Stop

By default, these functions are activated; but
they can be deactivated.
For more information on these functions, refer to
the corresponding sections.
The availability of the system depends on the
country you are driving in.
This system is only to be used on eligible
motorways and main roads.
Selecting/Deselecting the
system
It is configured in the ADAS touch screen
application.
The system's status is saved when the ignition is
switched off.
Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and
to

Cruise control - particular
recommendations.
This system automatically maintains the vehicle
speed at a value set by the driver (speed
setting), while respecting a safety distance from
the vehicle in front (target vehicle) previously set
by the driver. The system automatically manages
the acceleration and deceleration of the vehicle.
With the Stop
& Go function, the system
manages braking until the vehicle comes to a
complete stop and the restarting of the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
The system is not operational in the event of
a brake lamp failure.


To do this, the system uses a camera fitted at the
top of the windscreen and a radar fitted in the
front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver activates the direction
indicator to overtake a slower vehicle,
cruise control may temporarily reduce the
distance to the target vehicle to facilitate
overtaking, without exceeding the speed
setting.

Driving
if the front camera or the front radar is covered
by dirt, snow, ice or anything preventing the
sensing.
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 and/or in the
warning lamp display for seat belts and front
passenger airbag 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 .
The function comprises the "Coffee Break Alert"
system 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
By default, the function is automatically activated
at every engine start.
It is configured in the ADAS touch screen
application.
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

The system assesses the driver's level of alertness, fatigue and distraction by
identifying trajectory changes in relation to the
lane markings.
To do this, the system uses a camera, placed on
the upper part of the windscreen.
This system is particularly suited to fast roads
(speed higher than 43 mph (70
km/h)).
At a first alert level, the driver is warned by
the message "Caution!“, accompanied by an
audible signal.
After three first-level alerts, the system triggers
a further alert with the message " Driving

Driving
6This system detects and signals the proximity of
obstacles (e.g. pedestrian, vehicle, tree, barrier)
using sensors located in the bumper.
Rear parking sensors
â–º Engage reverse gear to start the system
(confirmed by an audible signal).
The system is switched off when reverse gear is
disengaged.
Audible assistance

The system signals the presence of obstacles
which are both within the sensors’ detection zone
and in the vehicle path defined by the direction of
the steering wheel.


Depending on version, in the example shown,
only the obstacles present in the shaded area
will be signalled by the audible assistance.
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
When the distance between the vehicle and
the obstacle becomes less than about thirty
centimetres, the audible signal becomes
continuous.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
Adjusting the audible signalPressing this button in the touch
screen opens the window for
adjusting the volume of the audible signal.
Visual assistance

This supplements the audible signal, without
taking account of the vehicle's trajectory, by
displaying bars on the screen that represent the
distance between the obstacle and the vehicle
(white: more distant, orange: close, red: very
close).
When the obstacle is very close, the "Danger"
symbol is displayed on the screen.
Front parking sensors
Supplementing the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of the
vehicle is below 6 mph (10
km/h).
Front parking sensor operation is suspended if
the vehicle stops for more than three seconds in
forward gear, if an obstacle is no longer detected
or the vehicle speed exceeds 6
mph (10 km/h).
The sound emitted by the speaker (front or rear) locates the obstacle relative to
the vehicle, whether in front of or behind it on
its path.
Deactivation/Activation
It is configured in the ADAS touch screen
application.
If the function is deactivated, this indicator
lamp lights up on the instrument panel.
The system status is saved when the ignition is
switched off.

specific trade name, etc.) to ensure correct
operation of the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 53 litres
(Petrol) or 40 litres (Rechargeable hybrid).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp lights up on the instrument
panel, accompanied by the display of a message
and an audible signal. When it first comes on,
about 6 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by the message and the audible
signal. When driving, this message and audible
signal are repeated with increasing frequency as
the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
A small arrow by the warning lamp indicates on which side of the vehicle the
fuel filler flap is located.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Any addition of fuel must be in quantities of at
least 10 litres, in order to be registered by the
fuel gauge.
Opening the filler flap may create a noise caused
by an inrush of air. This vacuum is entirely
normal, resulting from the sealing of the fuel
system.
