Electronic stability control
(ESC)
The electronic stability control programme includes the following systems:
–

Anti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–


Emergency braking assistance (EBA).
–


Post Collision Safety Brake (PCSB).
–


Anti-slip regulation (ASR).
–


Dynamic stability control (DSC).
Anti-lock braking system (ABS)/Electronic brake force
distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
Electronic brake force distribution (EBFD)
manages overall braking pressure on each
individual wheel.
►

When braking in an emergency
, depress
the pedal very firmly and maintain this
pressure.
Normal operation of the ABS may make
itself felt by slight vibrations of the brake
pedal.
The fixed illumination of this warning lamp signals that there is a fault with the ABS.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp, when lit together with the STOP and ABS warning lamps,
accompanied by a message and an audible
signal, indicates an EBFD malfunction.
You must stop the vehicle.
Stop as soon as it is safe to do so and switch off
the ignition.
Contact a CITROËN dealer or a qualified
workshop.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact
Have it checked by a CITROËN dealer or
a qualified workshop.
Post Collision Safety Brake
(PCSB)
If an accident is detected, the vehicle initiates
automatic post collision braking. The goal of this
system is to reduce the risk of further collisions if
the driver does not react.
The system is not operational if the capability
of the vehicle is to trigger and execute the

immediately share your photos and videos on
social networks or by email.
An audible signal confirms that the request has
been acknowledged.
Resetting the system
► Press and hold these 2 buttons
simultaneously to reset the
system.
This action erases all data recorded in the
camera and reinitialises the camera’s default
pairing code.
For safety reasons, the driver must not
use the ConnectedCAM Citroën
application from a smartphone while driving.
He or she must perform any action requiring
sustained attention when the vehicle is
stationary.
Malfunction
When a system fault occurs, the indicator
lamp in the button flashes.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Driving and manoeuvring
aids - General
recommendations
Driving and manoeuvring aids cannot, in
any circumstances, replace the need for
vigilance on the part of the driver.
The driver must comply with the Highway
Code, must remain in control of the vehicle in
all circumstances and must be able to retake
control of it at all times. The driver must adapt
the speed to climatic conditions, traffic and
the state of the road.
It is the driver's responsibility to constantly
monitor traffic conditions, assess the distance
and relative speed of other vehicles, and
anticipate their manoeuvres before using the
direction indicator and changing lanes.
These systems do not make it possible to
exceed the laws of physics.
Driving aids
You should hold the steering wheel with
both hands, always use the door and interior
mirrors, always leave your feet close to the
pedals and take a break every 2 hours.
Manoeuvring aids
The driver must always check the
surroundings of the vehicle before and during
the whole manoeuvre, in particular using the
mirrors.
Radar(s)
The operation of the radar(s), along with
any associated functions, may be affected
by the accumulation of dirt (e.g.
mud, ice),
in poor weather conditions (e.g.
heavy rain,
snow), or if the bumpers are damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar(s).


Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,

the displayed speed setting flashes.
►
Release the accelerator pedal to return to
below the speed setting.
When exceeding the speed is not due to the
driver's action (e.g.

in case of a steep slope), an
audible signal is triggered immediately.
On a steep descent or in the event of
sharp acceleration, the speed limiter will
not be able to prevent the vehicle from
exceeding the speed setting.
If necessary, apply the brakes to control your
vehicle’s speed.
When the vehicle speed returns to the speed
setting level, the speed limiter operates again:
the speed setting display becomes fixed again.
Off
► Press 1-LIMIT: the speed limiter information
display disappears.
Malfunction
In the event of a malfunction, dashes are
displayed flashing and then fixed instead of the
speed setting.
Have it checked by a CITROËN dealer or a
qualified workshop.
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
