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
.

Safety
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 to trigger and execute the automatic
post collision braking is not available, as it can
occur in destructive accidents or in other specific
accident scenarios.
It is possible to override the automatic braking by
pressing the brake pedal or accelerator pedal.
Operating conditions
The system operates, if the following conditions
are met:
–

Airbags or pyrotechnic seat belt pretensioners
have been deployed by the collision.
–


Braking systems and electric functions remain
continuously operational during and after
collision.
–


Driver has not depressed the brake or
accelerator pedal.
Malfunction
In the event of a
malfunction, one of these warning lamps will come on fixed on the
instrument panel, accompanied by the Service
warning lamp, the display of a message and an
audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Emergency braking
assistance (EBA)
This system reduces the emergency stopping
distance, by optimising the braking pressure.
It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
/ Dynamic stability control
(DSC)
Anti-slip regulation (or traction control) optimises
traction by using engine braking and by applying
the brakes on the driving wheels to avoid one
or more wheels spinning. It also enhances the
vehicle's directional stability.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.

79
Safety
5These systems are activated automatically every
time the vehicle is started.
These systems are activated in the event of a problem with grip or trajectory
(confirmed by this warning lamp flashing on the
instrument panel).
Deactivation/Reactivation
In exceptional conditions (e.g. moving a vehicle
that is bogged down in mud, stuck in snow , on
loose soil), it may prove useful to deactivate the
ASR system, so that the wheels can move freely
and regain grip.
Reactivate the system as soon as the level of
grip permits.
With Touch screen BLUETOOTH audio
system or MyCitroën Play
The ASR system is deactivated/ reactivated in the Driving touch screen
menu.
With MyCitroën Drive
The ASR system is deactivated/ reactivated in the Vehicle touch screen
menu.
With MyCitroën Drive Plus
The ASR system is deactivated/ reactivated in the ADAS touch screen
application.
Deactivation of the ASR system is
indicated by this indicator lamp on the
instrument panel coming on and the display of a
message.
The ASR system is automatically reactivated
every time the ignition is switched off or at
speeds over 31 mph (50 km/h)
Reactivation is manual below 31 mph (50 km/h).
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.
ASR/DSC
These systems enhance safety during
normal driving, but should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels
(tyres and rims), braking and electronic
components, as well as the assembly and
repair procedures provided by CITROËN
dealers.
In order to ensure that these systems remain
effective in wintry conditions, the use of snow
or all-season tyres is recommended. All four
wheels must be fitted with tyres approved for
your vehicle.
All tyre specifications are listed on the
tyre/paint label. For more information
on Identification markings , refer to the
corresponding section.
Seat belts
Inertia reel
The seat belts are equipped with an inertia
reel which allows the strap length to adjust
automatically to the shape of the user. The seat
belt returns to its storage automatically when it
is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiting system

80
Safety
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Front seat belts
The front seat belts are fitted with a pyrotechnic
pretensioning system and a force limiting
system.
Rear seat belts

Each of the rear seats has a three-point seat belt
with inertia reel.
The outer seats are fitted with a pyrotechnic
pretensioning and force limiting system.
Fastening
► Pull the strap, then insert the tongue into the
buckle.
►

Check that the seat belt is fastened correctly
by pulling on the strap.
Unfastening
► Press the red button on the buckle.

Advice
The driver must ensure that passengers use the seat belts correctly and that they
are all fastened before setting off.
Wherever seated in the vehicle, you must
always fasten the seat belt, even for short
journeys.
Do not invert the seat belt buckles, as they
will not fulfil their role properly.
To ensure the proper functioning of the belt
buckles, make sure that there are no foreign
bodies present (e.g.
a coin) before fastening.
Before and after use, ensure that the seat belt
is reeled in correctly.
After folding or moving a seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly.
Installation
The lower part of the strap must be
positioned as low as possible over the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
At the front, adjusting the position of the
seat belt may require the seat height to be
adjusted.
In order to be effective, a seat belt must:
–

be tightened as close to the body as
possible.
–


be pulled in front of you with a smooth
movement, checking that it is not twisted.
–


must only be used to secure one person.
–


not show signs of tearing or fraying.
–


not be changed or modified, in order to
