The 400
V traction battery 2 uses Lithium-Ion
technology. It stores and supplies the energy
required for the operation of the electric motor,
air conditioning and heating. Its charge level is
represented by an indicator and a reserve power
warning lamp on the instrument panel.
The 12
V accessory battery 3 powers the
vehicle’s conventional electrical system. It is
recharged automatically by the traction battery
via the on-board charger.
The heat pump
4 provides passenger
compartment heating and regulates traction
battery and on-board charger cooling.
The on-board charger 5 manages the domestic
charging
(mode 2) and accelerated charging
(mode 3) of the traction battery as well as the
recharging of the 12
V accessory battery.
The electric motor
6 provides propulsion in
accordance with the selected driving mode and
driving conditions. It recovers energy during
vehicle braking and deceleration
phases.

Safety
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 and upright sitting position.
Fasten your seat belt and position it correctly.
Do not place anything between the occupants
and the airbags (e.g.
child, animal, object), do
not fix or attach anything near or in the path of
the airbags, as this could cause injuries when
they are deployed.
Never modify the original definition of the
vehicle, particularly in the area directly around
the airbags.
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 bag inflates
almost instantly (within a few milliseconds)
then deflates within the same time,
discharging the hot gas via openings provided
for this purpose.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
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 seat covers
compatible with the deployment of these
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 (e.g.
clothing) as this could cause
injuries to the chest or arm when the 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!
All work must be carried out only 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.
Child seats
The legislation on carrying children is 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 one
and a half metres 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.
–

in the "rearward facing" position both in the
front and in the rear.

When fitting an ISOFIX child seat to the
left-hand rear seat of the bench seat,
before fitting the seat, first move the centre
rear seat belt towards the middle of the
vehicle, so as to avoid the seat interfering
with the operation of the seat belt.
An incorrectly installed child seat in a vehicle compromises the child's safety in
the event of an accident.
Strictly observe the fitting instructions
provided in the user guide supplied with the
child seat.
For information about the options for
fitting ISOFIX child seats in your vehicle,
refer to the summary table.
