Do not disconnect the (+) terminal while the

engine is running.

► Connect the other end of the green or black

cable to earth point C on the broken down

vehicle.

► Start the engine of the vehicle with the good

battery and leave it running for a few minutes.

► Operate the starter on the broken down

vehicle and let the engine run.

engine mounting.

► Reﬁt the plastic cover to the (+) terminal, if

your vehicle has one.

► Allow the engine to run for at least 30

minutes, by driving or with the vehicle stationary,

so that the battery reaches an adequate state of

charge.

Starting using another

battery

When your vehicle's battery is discharged, the

engine can be started using a backup battery

(external or from another vehicle) and jump

leads or a battery booster.

Some functions, including Stop & Start,

are not available if the battery is not

suﬃciently charged.

the positive terminal (+) of back-up battery B or

the booster.

Never try to start the engine by

connecting a battery charger.

Charging the battery using a

battery charger

For optimum service life of the battery, it is

essential to maintain an adequate state of

charge.

Never use a 24 V or higher battery booster.

Check beforehand that the back-up battery

has a nominal voltage of 12 V and a capacity

at least equal to that of the discharged

battery.

► Connect one end of the green or black cable

to the negative terminal (-) of back-up battery B

In the event of a breakdown

In some circumstances, it may be necessary to

charge the battery:

– if the vehicle is to be taken oﬀ the road for

several weeks.

24v

12v

Contact a CITROËN dealer or a qualiﬁed

workshop.

If this label is present, use only a 12 V

charger to avoid causing irreversible

damage to the electrical components related

to the Stop & Start system.

To charge the vehicle's battery yourself,

use only a charger compatible with

lead-acid batteries with a nominal voltage of

12 V.

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.

Follow the instructions provided by the

manufacturer of the charger.

Never reverse polarities.

► Switch oﬀ charger B before connecting

the cables to the battery, so as to avoid any

dangerous sparks.

► Ensure that the charger cables are in good

condition.

It is not necessary to disconnect the

battery.

► Lift the plastic cover on the (+) terminal, if the

vehicle has one.

► Connect the cables of charger B as follows:

• the positive (+) red cable to the (+) terminal

of battery A,

• the negative (-) black cable to earth point C

on the vehicle.

► At the end of the charging operation, switch

oﬀ charger B before disconnecting the cables

from battery A.

► Switch oﬀ the ignition.

► Switch oﬀ all electrical consumers (audio

system, lighting, wipers, etc.).

Disconnecting the battery

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
