Lighting and visibility
Automatic windscreen wipers
In AUTO mode, the front wipers work
automatically and adapt to the intensity of
precipitation depending on the sensitivity of the
sensor selected.
The rainfall detection function uses a rain/
sunshine sensor located at the top centre of the
windscreen, behind the rear view mirror.
In certain weather conditions (e.g. fog,
frost, snow , projections on salty roads),
the driver may have to return to manual
wiping.
Switching on/off
To switch on:
► Put the wiper control stalk in the AUT
O
position.
►

T
urn the ring to adjust the sensitivity of the
sensor.
A wiping cycle, accompanied by the display of
a message, confirms that the request has been
taken into account.
►

T
o switch off, put the wiper control stalk in
another position or in the 0 position.
Adjusting the sensitivity

The first position (upper) corresponds to the
lowest sensitivity of the sensor.
The last position (lower) corresponds to the
highest sensitivity of the sensor.
The higher the sensitivity, the faster the system
reacts and increases the wiping frequency.
A rotation of the ring from a higher position to a
lower position triggers a confirmation wiping.
After the ignition has been switched off
for more than 1 minute with the wiper
control stalk in the AUTO position, when the
ignition is switched on again:
–

the system works, depending on the
volume of rain detected, as soon as the
vehicle exceeds 6 mph (10 km/h), if the
outside temperature is below +3°C.
–


the system works immediately
, depending
on the volume of rain detected, if the outside
temperature is above +3°C.
Do not cover the rain/sunshine sensor.
When using an automatic car wash,
switch off the automatic wipers and the
ignition.
In winter, wait until the windscreen is
completely clear of ice before activating the
automatic wipers.
Malfunction
If a fault occurs with the automatic wipers, the
wipers operate in intermittent mode.
Have it checked by a CITROËN dealer or a
qualified workshop.
Special position of the
windscreen wipers
This maintenance position is used while cleaning
or replacing the wiper blades. It can also be
useful, in wintry weather (ice, snow), to release
the wiper blades from the windscreen.
To maintain the effectiveness of the flat wiper blades, it is advisable to:
–

handle them with care.
–


clean them regularly using soapy water
.
–

avoid using them to hold cardboard on the
windscreen.
–


replace them at the first signs of wear
.

Driving
6blow-out. This is because analysis of the
values read by the wheel's speed sensors
can take several minutes.
The alert may be delayed at speeds below
25 mph (40 km/h), or when adopting a sporty
driving mode.
The alert is kept active until the system is reinitialised.
Reinitialisation
► The system must be reinitialised after any
adjustment to the pressure of one or more tyres,
and after changing one or more wheels.
Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
With the vehicle stationary, the system
can be reinitialised via the Driving touch
screen menu.
With MyCitroën Drive
With the vehicle stationary, the system
can be reinitialised via the Vehicle touch

signal.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have it checked by a CITROËN dealer or a
qualified workshop.
Non-standard or 'space-saver' spare
wheel
The use of this type of spare wheel may
suspend tyre pressure monitoring.
In this case, the malfunction warning lamp
comes on and disappears once the wheel
has been replaced by one of uniform size (the
same as the others), the pressure readjusted
and the reinitialisation carried out.
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.

11 0
Driving
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 (e.g.
inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(e.g. headlamps of an oncoming vehicle, low
sun, reflections on a damp road, leaving a
tunnel, alternating shade and light) can also
impair detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
terrain.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors, as well as
any associated functions, may be disrupted
by noise pollution such as that emitted by
noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30
cm away
from the radar, sensors and cameras.
Mats/Pedal trims
The use of mats or pedal trims not
approved by CITROËN may interfere with
the operation of the speed limiter or cruise
control.
To avoid any risk of jamming the pedals:
–

Ensure that the mat is secured correctly
.
–

Never fit one mat on top of another
.

Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The system may be temporarily disturbed by certain weather conditions (e.g. rain,
hail).
In particular, driving on a wet road or going
from a dry to a wet area can cause false
alerts (e.g.
presence of a cloud of water
droplets in the blind spot interpreted as a
vehicle).
In bad or wintry weather, ensure that the
sensors are not covered by mud, ice or snow.
Take care not to cover the warning zone in
the door mirrors, or the detection zones on
the front and rear bumpers with adhesive
labels or other objects; they may hamper
correct operation of the system.
