In the event of a breakdown
Ancillaries battery
All of the electrical components on your vehicle
(with the exception of the electric motor, the
heating and the air conditioning) are powered
by the ancillaries battery.
It is located in the front compartment under
the bonnet and is charged by the main battery
during phases of operation ("Ready" lamp on in
the instrument panel) and charging.
If the ancillaries battery is discharged,
the electric motor cannot be started and
charging of the main battery is no longer
possible.
It is not recommended to disconnect the
battery.
However, during a prolonged period of
more than one month without using your
vehicle, it may be necessary, in winter,
to disconnect the battery and store it to
prevent the electrolyte freezing.
After prolonged disconnection of the
battery, you must consult a CITROËN
dealer or a qualified workshop in order to
have the electronic computer reset.
