normal or fast.  
electrical installation you want to use  
meets standards* and is compatible  
with the rating of your charging unit.  
If in doubt, call upon a professional  
installer.  
Normal charging should be favoured; it is done  
from a domestic mains power point.  
Fast charging is done at a compatible fast  
charging station.  
There are sockets available that are  
specially designed for charging electric  
vehicles.  
For sockets dedicated to charging an  
electric vehicle, refer to the installation  
instructions for the socket.  
In all cases, it is recommended that  
that you first have an initial check  
and then regular checks carried out  
on your installation by a qualified  
electrician.

the vehicle, charging cable, charging  
unit or charging point, even for a short  
time.  
It is also important that you take advice  
from your doctor on the precautions to  
take and observe.  
In most European countries, CITROËN  
has established a partnership with a  
specialist company that can check and  
bring your electrical installation up to  
standard. For more information, contact  
a CITROËN dealer.

interrupts the charging procedure. It will  
then be necessary to disconnect and  
reconnect the charging cable plug to  
continue charging.  
If the 12 V battery is discharged, it is not  
possible to charge the main battery.  
This type of control unit that has a system for  
recognising the type of power point (depending  
on country). It detects the power rating of your  
domestic power point and is able to support  
and select the best current rating to ensure  
safe charging:

the main battery, never touch liquids  
coming from this component.  
In the event of contact with your body,  
wash abundantly with water and contact  
a doctor without delay.  
Vehicle out of use for a long  
period  
When your vehicle is going to be out  
of use for a long period, charge the  
main battery completely every three  
months (following the normal charging  
procedure).  
Before charging, check that the  
12 V battery is not disconnected or  
discharged. If this is the case, refer  
to the "12 V battery" section for  
reconnecting or charging the battery.  
To optimise the service life of the  
main battery, recharge it completely  
every 2 weeks.  
After removing the charging plug from  
the vehicle's socket, do not leave  
the cable connected to the electric  
power point (risk of short circuit or  
electrocution if there is contact or  
immersion in water).  
For a complete charge, follow the  
normal charging procedure (domestic  
power point) without interruption, until it  
stops automatically (charging warning  
lamp goes off in the instrument panel).  
In addition, every 3 months, carry  
out this complete recharge of the  
main battery from a state of charge  
of 2 bars or less.  
In the event of an accident or an impact  
to the underbody of the vehicle (contact  
with a raised kerb, a bollard, street  
furniture, etc.), the electric circuit or the  
main battery may be damaged. Have  
your vehicle checked by a CITROËN  
dealer or a qualified workshop.

Practical information  
The charging warning lamp in the instrument  
panel goes off when charging is complete.  
F
Check that the charging warning  
lamp in the instrument panel is  
on fixed.  
If the exterior temperature is  
below 0 °C, the charging time may be  
longer.

If this is not the case, charging has not started;  
check the operating instructions for the  
charging station.  
F
During fast charging, the vehicle's air  
conditioning may start automatically,  
if needed to cool the main battery. It is  
therefore perfectly normal to hear the  
noise of a fan running from outside the  
vehicle and to see a puddle of water  
form under the vehicle.  
As a safety measure, the motor will  
not start when the charging cable is  
connected to the vehicle's socket.  
Also, any attempt to start the motor  
interrupts the charging procedure. It  
will then be necessary to disconnect  
and reconnect the charging cable to  
the vehicle's socket, then to restart the  
charging following the instructions for  
using the charging station.  
Vehicle out of use for a long  
period  
When your vehicle is going to be out  
of use for a long period, charge the  
main battery completely every three  
months (following the normal charging  
procedure).  
Before charging, check that the  
12 V battery is not disconnected or  
discharged. If this is the case, refer  
to the "12 V battery" section for  
reconnecting or charging the battery.  
Fast charging stops automatically  
when the main battery is around 80%  
charged. It is possible to attain a charge  
of 100% by restarting the procedure.
