emergency call is made automatically.
The eCall (SOS) system is a public
service of general interest and is
free-of-charge.

78
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.

System that protects the driver and front
passenger in the event of a serious front impact,
limiting the risk of head and chest injury.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger airbag is
fitted in the dashboard above the glove box.
Deployment
They deploy, except the front passenger airbag
if it is deactivated*, in the event of a serious front
impact to all or part of the front impact zone A.
The front airbag inflates between the thorax and
head of the front occupant of the vehicle and the
steering wheel, driver's side, and the dashboard,
passenger's side, to cushion their forward
movement.
* For more information on Deactivating the front passenger airbag, refer t\
o the corresponding section.
Lateral airbags

This system protects the driver and front
passenger in the event of a serious side impact,
limiting the risk of injury to the chest, between
the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, on the door side.
Deployment
The lateral airbags are deployed on one side in
the event of a serious side impact applied to all
or part of the side impact zone B.
The lateral airbag inflates between the chest of
the vehicle's occupant and the corresponding
door panel.
Curtain airbags
System contributing towards greater protection
for the driver and passengers (with the exception
of the rear centre passenger) in the event of a
serious side impact in order to limit the risk of
injury to the side of the head.
Each curtain airbag is built into the pillars and
the upper passenger compartment area.
Deployment
It deploys simultaneously with the corresponding
lateral airbag in the event of a serious side
impact applied to all or part of the side impact
zone B.
The curtain airbag inflates between the front
and rear occupants of the vehicle and the
corresponding windows.
Malfunction
In the event of a malfunction,
these warning lamps light up on
the instrument panel. Contact a CITROËN dealer
or a qualified workshop to have the system
checked.
The airbags may not be deployed in the event of
a serious impact.

Driving
Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when
driving, the driver must pay particular attention.
When manoeuvring, the driver must always
check the vehicle's immediate surroundings.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during
charging to cool the on-board charger and the
traction battery.
On the inside
During use, you may hear certain perfectly
normal noises specific to electric vehicles, such
as:
–

T
raction battery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
–

Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer , observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
►

Reduce speed and lower the engine speed to
limit the amount of heating produced.
►


Pay constant attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the
vehicle and switch off the engine as soon as
possible.
Brakes
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
