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

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 (+)

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.
