B or the booster (or to an earth point on the
assisting vehicle).
Never start the engine by connecting
a battery charger.
Never use a 24 V or higher battery

Check beforehand that the backup
battery has a nominal voltage of 12 V and
a capacity at least equal to that of the
discharged battery.
The two vehicles must not be in contact
with each other.
F Connect the other end of the green or black
cable to earth point C on the broken down
vehicle.
For access to the (+) terminal:

Charging the battery using
a battery charger
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
would mean a risk of toxic and corrosive
acid leaking.
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
-
-
using the vehicle mainly for short journeys,
if the vehicle is to be taken off the road for
several weeks.
Contact a CITROËN dealer or a qualified
workshop.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
To charge the vehicle's battery yourself,
use only a charger compatible with lead-
acid batteries with a nominal voltage of
12 V.
F Switch off charger B before connecting the
cables to the battery, so as to avoid any
dangerous sparks.
F Ensure that the charger cables are in good
condition.
Disconnecting the battery
F If the vehicle has one, lift the plastic cover
on the (+) terminal.
F Connect the cables of charger B as follows:
In order to maintain an adequate state
of charge for starting the engine, it is
recommended that the battery be disconnected
if the vehicle is taken out of service for a long
period.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
-
the positive (+) red cable to the (+)
terminal of battery A,
-
the negative (-) black cable to earth point
C on the vehicle.
Before disconnecting the battery:
F close all openings (doors, tailgate, windows,
sunroof),
F switch off all electrical consumers (audio
system, wipers, lighting, etc.),
It is not necessary to disconnect the
battery.

F At the end of the charging operation, switch
off charger B before disconnecting the
cables from battery A.
217
In the event of a breakdown
F switch off the ignition and wait for four
minutes.
At the battery, it is only necessary to
disconnect the (+) terminal.
Reconnecting the (+) terminal
After reconnecting the battery
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting
the engine, in order to enable the electronic
systems to initialise.
Quick-release terminal clamp
Disconnecting the (+) terminal
If minor problems nevertheless persist
following this operation, contact a CITROËN
dealer or a qualified workshop.
Referring to the corresponding section, you
must reinitialise certain systems yourself, such
as:
-
the key with remote control or electronic key
(depending on version),
F Raise the lever A fully.
F Replace the open clamp B on the (+)
terminal.
F Push the clamp B fully down.
F Lower the lever A to lock the clamp B.
F Depending on equipment, lower the plastic
cover on the (+) terminal.
-
-
-
-
the sunroof and its electric blind,
the electric windows,
the date and time,
the preset radio stations.
F Depending on equipment, lift the plastic
cover on the (+) terminal.
F Raise the lever A fully to release the clamp B.
F Remove the clamp B by lifting it off.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous
period of immobilisation of the vehicle,
a period which depends on the exterior
temperature and the state of charge of the
battery (up to about 8 hours).
Do not apply force when pressing the
lever, as if the clamp is not positioned
correctly, locking will be impossible; start
the procedure again.
