Overview
– Domestic charging in mode 2 using a
domestic socket and associated charging cable
7
.
–

Accelerated charging in mode 3 using an
accelerated charging unit (W

allbox).
–

Superfast charging in mode 4 using a fast
public charger

.
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
General safety
recommendations
Do not remove the labels attached in
different places on your vehicle. They
include safety warnings as well as
identification information for the vehicle.
For all work on your vehicle, use a
qualified workshop that has the technical
information, skills and equipment required, all
of which a CITROËN dealer is able to
provide.
Depending on country regulations,
certain safety equipment may be
mandatory: high visibility safety vests,
warning triangles, breathalysers, spare bulbs,
spare fuses, fire extinguisher, first aid kit, mud
flaps at the rear of the vehicle, etc.
Installing electrical accessories:
– The fitting of electrical equipment or
accessories not approved by CITROËN may
cause excessive current consumption and
faults and failures with the electrical system
of your vehicle. Contact a CITROËN dealer
for information on the range of approved
accessories.
–

As a safety measure, access to the
diagnostic socket, used for the vehicle's
electronic systems, is reserved strictly for
CITROËN dealers or qualified workshops,
equipped with the special tools required (risk
of malfunctions of the vehicle's electronic
systems that could cause breakdowns or
serious accidents). The Manufacturer cannot
be held responsible if this advice is not
followed.
–

Any modification or adaptation not intended
or authorised by CITROËN or carried out
without meeting the technical requirements
defined by the Manufacturer will result in the
suspension of the commercial warranty

.
Installation of accessory radio
communication transmitters
Before installing a radio communication
transmitter with an external aerial, you must
without fail contact a CITROËN dealer for
the specification of transmitters which can
be fitted (frequency, maximum power, aerial
position, specific installation requirements),
in line with the Vehicle Electromagnetic
Compatibility Directive (2004/104/EC).
Declarations of conformity for radio
equipment
The relevant certificates are available on the
brand website:
http://service.citroen.com/ACddb/
Hazard warning lamps



► Pressing this red button causes all the
direction indicators to flash.
They can work with the ignition switched off.
Automatic operation of hazard warning lamps
When braking in an emergency, depending on
the rate of deceleration, the hazard warning
lamps come on automatically. They switch off
automatically when you next accelerate.
They can be turned off by pressing the button
again.

In the event of a breakdown
8After changing a wheel
With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, Adaptive cruise control,
etc.).
Do not exceed the maximum authorised
speed of 50 mph (80 km/h).
Driving with more than one "space-saver"
type spare wheel is prohibited.
Visit a CITROËN dealer or a qualified
workshop.
Have the tightening of the spare wheel's bolts
and its tyre pressure checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.

Fuses
Changing a fuse
All work must be carried out only by a
CITROËN dealer or a qualified workshop
The replacement of a fuse by a third party
could cause a serious malfunction of the
vehicle.
Installing electrical accessories
The vehicle's electrical system is
designed to operate with standard or optional
equipment.
Before fitting other electrical equipment
or accessories to your vehicle, contact a
CITROËN dealer or a qualified workshop.
CITROËN accepts no responsibility for
the cost incurred in repairing the vehicle
or for rectifying malfunctions resulting from
the installation of accessories not supplied or
not recommended by CITROËN and not
installed in accordance with its
recommendations, in particular when the
combined power consumption of all of the
additional equipment connected exceeds 10
milliamperes.
12 V battery / Accessory
battery
Lead-acid starter batteries
These batteries contain harmful
substances (sulphuric acid and lead).
They must be disposed of in accordance
with regulations and must never under any
circumstances be discarded with household
waste.
Dispose of used batteries at a designated
collection point.
Protect your eyes and face before
handling the battery.
All operations on the battery must be carried
out in a well ventilated area and away from
naked flames and sources of sparks, to avoid
any risk of explosion or fire.
Wash your hands afterwards.
Frozen battery
Never try to charge a frozen battery - risk
of explosion!
If the battery has frozen, have it checked by a
CITROËN dealer or by a qualified workshop,
who will verify that the internal components
have not been damaged and that the case
has not cracked, which could lead to a risk of
leakage of toxic and corrosive acid.
