Access to the battery

Procedure for starting the engine using another
battery or charging a discharged battery.

The presence of this label, in particular
with the Stop & Start system, indicates
the use of a 12 V lead-acid battery with
special technology and specification;
the involvement of a CITROËN dealer or
a qualified workshop is essential when
replacing or disconnecting the battery.

After refitting the battery, the Stop & Start
system will only be active after a continuous
period of immobilisation of the vehicle,
a period which depends on the climatic
conditions and the state of charge of the
battery (up to about 8 hours).

In the event of a breakdown

266

C4-2_en_Chap08_en-cas-de-panne_ed02-2015

When your vehicle's battery is discharged, the
engine can be started using a slave battery
(external or on another vehicle) and jump lead
cables.

Starting using another
battery

First check that the slave battery has a
nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
Do not try to start the engine by
connecting a battery charger.
Do not disconnect the (+) terminal when
the engine is running.

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.

If the engine does not start straight away,
switch off the ignition and wait a few
moments before trying again.

Remove the plastic cover from

the (+) terminal, if your vehicle has one.

F Connect the red cable to the positive

terminal (+) of the flat battery A, then to the
positive terminal (+) of the slave battery B.

Connect one end of the green or black

cable to the negative terminal (-) of the
slave battery B

(or earth point on the other

vehicle).

Connect the other end of the green or black

cable to the earth point C

on the broken

down vehicle (or on the engine mounting).

Wait until the engine returns to idle then

disconnect the jump lead cables in the
reverse order.

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

your vehicle has one.

Charging the battery using
a battery charger

Disconnect the battery from the vehicle.

F Follow the instructions for use provided by

the manufacturer of the charger.

Connect the battery starting with the

negative terminal (-).

Check that the terminals and connectors

are clean. If they are covered with sulphate
(whitish or greenish deposit), remove them
and clean them.

Reinitialisation after
reconnection

After any reconnection of the battery, switch on
the ignition and wait at least one minute before
starting, to allow time for the initialisation of the
electronic systems.
By referring to the corresponding sections, you
should set or initialise the following systems
yourself:
-

one-touch electric windows,

- time and date,
- audio and navigation system settings.
Check that no alert message or warning lamp
comes on after switching on the ignition.
However, if minor problems persist after
carrying out these operations, contact a
CITROËN dealer or a qualified workshop.

Reconnecting the (+) cable

Position the open clamp E of the cable on

the positive post (+) of the battery.

Press vertically on the clamp E to position

it correctly on the battery.

Lock the clamp by spreading the

positioning lug and then lowering the tab D.

Disconnecting the (+) cable

Raise the locking tab D fully to release the

cable terminal clamp E.

Do not apply excessive force on the
tab as locking will not be possible if the
clamp is not positioned correctly; start
the procedure again.

With Stop & Start, the battery does not
have to be disconnected for charging.

Before disconnecting the battery

Wait 2 minutes after switching off the ignition
before disconnecting the battery.
Close the windows and the doors before
disconnecting the battery.

In the event of a breakdown

268

C4-2_en_Chap08_en-cas-de-panne_ed02-2015

Protect your eyes and face before
handling the battery.
All operations on the battery must be
carried out in a well ventilated area and
away from naked flames and sources
of sparks, so as to avoid the risk of
explosion or fire.
Do not try to charge a frozen battery;
the battery must first be thawed out to
avoid the risk of explosion. If the battery
has been frozen, before charging have
it checked by a CITROËN dealer or a
qualified workshop who will check that
the internal components have not been
damaged and the casing is not cracked,
which could cause a leak of toxic and
corrosive acid.
Do not reverse the polarity and use only
a 12 V charger.
Do not disconnect the terminals while
the engine is running.
Do not charge the batteries without
disconnecting the terminals first.
Wash your hands afterwards.

Do not push the vehicle to start the
engine if your vehicle has an automatic
gearbox.

Some functions are not available if the
battery is not sufficiently charged.

It is advisable to disconnect the battery if
the vehicle is to be left unused for more
than one month.

The batteries contain harmful substances
such as sulphuric acid and lead. They
must be disposed of in accordance
with regulations and must not, in any
circumstances, be discarded with household
waste.
Take used remote control batteries and
vehicle batteries to a special collection point.
