deactivation switch.
12 V accessory sockets

► Always use the correct adapter to connect a
12 V accessory (max. power: 120 W).
Observe the maximum power rating to
avoid damaging your accessory.
The connection of an electrical device not approved by CITROËN, such as a
USB charger, may adversely affect the
operation of vehicle electrical systems,
causing faults such as poor radio reception or
interference with displays in the screens.
Wireless smartphone
charger



It allows wireless charging of a portable device
such as a smartphone, using the magnetic
induction principle, in accordance with the Qi 1.1
standard.
The portable device to be charged must be
compatible with the Qi standard, either by design
or by using a compatible holder or shell.
The charging area is identified by the Qi symbol.
The charger works with the engine running and
with the Stop & Start system in STOP mode.
Charging is managed by the smartphone.
With Keyless Entry and Starting, the charger’s
operation may be briefly disrupted when a door
is opened or the ignition is switched off.
Charging
► With the charging area clear , place a device in its centre.

When the portable device is detected, the
charger’s indicator lamp lights up green. It
remains lit for the whole time that the battery is
being charged.
The system is not designed to charge
multiple devices simultaneously.


Do not leave any metal objects (coins,
keys, vehicle remote control, etc.) in the
charging area while a device is being
charged, due to the risk of overheating or
interrupting the charging process.
Operating check
The state of the indicator lamp allows the
operation of the charger to be monitored.

Safety
Front airbags

This system protects the driver and front
passenger in the event of a serious front impact,
in order to limit the risk of head and chest
injuries.
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 to the corresponding section.
Lateral airbags

In the event of a serious side impact, this system
protects the driver and front passenger to
mitigate the risk of injury to the chest between the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest
frame, 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 hip and
shoulder 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
If this warning lamp comes on in the instrument panel, you must contact a
CITROËN dealer or a qualified workshop to have
the system checked.
The airbags may no longer be deployed in the
event of a serious impact.
In the event of a minor impact or bump at
the side of the vehicle or if the vehicle
rolls over, the airbags may not be deployed.
In the event of a rear or front collision, none of
the lateral airbags are deployed.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose.

Front airbags
Do not drive holding the steering wheel
by its spokes or resting your hands on the
centre part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fix or attach anything to the steering
wheel or dashboard, as this could cause
injuries when the airbags are deployed.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment of the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, contact a
CITROËN dealer.
Do not fix or attach anything to the seat
backrests (clothes, etc.), as this could cause
injuries to the thorax or arm when the lateral
airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary.
The vehicle's front door panels include side
impact sensors.
A damaged door or any unauthorised or
incorrectly executed work (modification or
repair) on the front doors or their interior trim
could compromise the operation of these
sensors - risk of malfunction of the lateral
airbags!
Such work must only be done by a CITROËN
dealer or a qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof,
as this could cause head injuries when the
curtain airbag is deployed.
Do not remove the grab handles installed on
the roof, as they play a part in securing the
curtain airbags.
Child seats
The regulations on carrying children are specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please observe the
following recommendations:
– In accordance with European regulations, all
children under the age of 12 or less than 4
ft 11” (150 cm) tall must travel in approved
child seats suited to their weight , on seats
fitted with a seat belt or ISOFIX mountings.
– Statistically, the safest seats in your
vehicle for carrying children are the rear
seats.
– Children weighing less than 9 kg must
travel in the "rear facing" position, whether in
the front or rear of the vehicle.

Frequently asked
questions
The following information groups together the answers to the most frequently asked questions
concerning your audio system. With the engine off, the audio system
switches off after a few minutes of use.
When the engine is switched off, the audio
system operating time depends on the state of
charge of the battery.
The switch-off is normal: the audio system
switches to economy mode and switches off to
avoid discharging the vehicle's battery.
► Start the vehicle’
s engine to increase the charge of the battery.
The message "the audio system is
overheated" is displayed onscreen.
To protect the installation if the ambient
temperature is too high, the audio system
switches to an automatic thermal protection
mode, in which the volume may be decreased or
the CD player stopped.
► Switch the audio system off for a few minutes to allow the system to cool.
Radio
There is a difference in sound quality
between the different audio sources (radio,
CD, etc.).
For optimal listening quality, the audio settings
(Volume, Bass, Treble, Ambience and Loudness)
can be adjusted to different audio sources,
resulting in audible differences when switching
between sources (radio, CD, etc.).
► Check that the audio settings (V olume, Bass, Treble, Ambience and Loudness) are appropriate
to the sources being listened to. We recommend
setting the audio functions (Bass, Treble, Fr-Re
