Changing a fuse

The 2 fuseboxes are located below the dashboard and under the bonnet.

Replacing a fuse

Before replacing a fuse, you must:
-

ascertain the cause of the fault and have it
remedied,

-  switch off all electrical consumers,
-  park the vehicle and switch off the ignition,
-  identify the failed fuse using the allocation

tables and diagrams presented on the
following pages.

Good

Failed

Tweezer

If the fault recurs soon after replacing the
fuse, have the electrical system checked by a
CITROËN dealer or a qualified workshop.

When replacing a fuse, it is essential to:
-

use the special tweezer, located on the
cover close to the fusebox, to extract
the fuse from its housing and check the
condition of its filament,

always replace a failed fuse with one of
equivalent rating (same colour); using a
different rating could cause a malfunction
(risk of fire).

The replacement of a fuse not
mentioned in the tables below may
cause a serious malfunction on your
vehicle. Contact a CITROËN dealer or a
qualified workshop.

CITROËN will not accept any
responsibility for the costs incurred
in repairing your vehicle or for the
malfunctions resulting from the
installation of auxiliary accessories
which were not supplied or
recommended by CITROËN and which
were not installed in accordance with
its instructions, in particular where
the current consumption of all of
the additional equipment connected
exceeds 10 milliamps.

Installation of electrical
accessories

Your vehicle's electrical system is
designed to operate with standard or
optional equipment.
Before installing other electrical
equipment or accessories on your
vehicle, contact a CITROËN dealer or a
qualified workshop.

12 V battery

Access to the battery

The battery is located under the bonnet.
For access to the (+) terminal:
F

release the bonnet using the interior lever,

then the exterior safety catch,

raise the bonnet and secure it with its stay.

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.
Wash your hands afterwards.

If your vehicle has an automatic
gearbox, do not try to start the engine
by pushing the vehicle.

Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out
only by a CITROËN dealer or a qualified
workshop.

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

General points

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.

Lead-acid starter batteries

(+)

Positive terminal.

It has a quick-release clamp.

(-)

Negative terminal.

As the battery negative terminal is not
accessible, a remote earth point is located
close to the battery.

In the event of a breakdown

236

C5_en_Chap08_en-cas-de-panne_ed01-2016

Starting using another battery

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 or a battery booster.

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.

Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery
booster.
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.
The two vehicles must not be in contact
with each other.
Switch off the electrical consumers on
both vehicles (audio system, wipers,
lighting, ...).
Ensure that the jump lead cables do
not pass close to moving parts of the
engine (cooling fan, belts, ...).
Do not disconnect the (+) terminal when
the engine is running.

Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.

Raise the plastic cover on the (+) terminal,

if your vehicle has one.

F Connect the red cable to the positive

terminal (+) of the flat battery A (at
the metal elbow) then to the positive
terminal (+) of the slave battery B or the
booster.

Connect one end of the green or black

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

or the booster (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.

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.

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.

In the event of a breakdown

237

C5_en_Chap08_en-cas-de-panne_ed01-2016

Charging the battery using a battery charger

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:
-

if you use your vehicle essentially for short
journeys,

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

several weeks.

Contact a CITROËN dealer or a qualified
workshop.

If you envisage charging your vehicle's
battery yourself, use only a charger
compatible with lead-acid batteries of a
nominal voltage of 12 V.

Never try to charge a frozen battery.
If the battery has been frozen, 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.

It is not necessary to disconnect the
battery.

Follow the instructions for use provided
by the manufacturer of the charger.
Never reverse polarities.

If this label is present, it is essential
to use only a 12 V charger, to avoid
causing irreversible damage to the
electrical components related to the
Stop & Start system.

Switch off the ignition.

Switch off all electrical consumers (audio

system, lighting, wipers, ...).

Switch off the 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.

F Raise the plastic cover, if your vehicle has

one, on the (+) terminal.

Connect the charger B cables as follows:

- the positive (+) red cable to the (+)

terminal of the battery A,

- the negative (-) black cable to the earth

point C

on the vehicle.

At the end of the charging operation, switch

off the charger B before disconnecting the
cables from the battery A.

In the event of a breakdown

238

C5_en_Chap08_en-cas-de-panne_ed01-2016

Disconnecting the (+) terminal
F Raise the lever A

fully to release the clamp B.

Remove the clamp B by lifting it off.

Quick-release terminal clamp*

Reconnecting the (+) terminal
F Raise the lever A

fully.

Refit the open clamp B on the (+) terminal.

Push the clamp B fully down.

F Lower the lever A

to lock the clamp B.

Do not force the lever as locking will
not be possible if the clamp is not
positioned correctly; start the procedure
again.

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 taken out of service for a long
period.
Before disconnecting the battery:
F

close all openings (doors, boot, windows),

switch off all electrical consumers (audio

system, wipers, lighting, ...),

switch off the ignition and wait for

four minutes.

Having exposed the battery, it is only
necessary to disconnect the (+) terminal.

Following reconnection of the
battery

After reconnecting the battery, switch on the
ignition and wait 1 minute before starting the
engine to allow initialisation of the electronic
systems.
However, if minor problems persist following
this operation, contact a CITROËN dealer or a
qualified workshop.
Referring to the corresponding section, you
must yourself reinitialise or reset certain
systems, such as:
- the remote control,
-

the electric windows,

-  the panoramic sunroof blind,
-  the date and time in the audio system,
-  the radio preset stations.

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 ambient
temperature and the state of charge of
the battery (up to about 8 hours).

* Depending on version.
