allocation tables and diagrams.
T
o replace a fuse, it is essential to:
►

Use the special tweezers to extract the fuse
from its housing and check the condition of its
filament.
►


Always replace the failed fuse with a fuse of
the same rating (same colour); use of a different
rating may cause malfunctions - risk of fire!
If the fault recurs after replacing a fuse, have
the electrical system checked by a PEUGEOT


dealer or a qualified workshop.
The fuse allocation tables and the corresponding diagrams are available
from a PEUGEOT dealer or from a qualified
workshop.
The replacement of a fuse not shown in the allocation tables may cause a serious
malfunction of your vehicle. Contact a
PEUGEOT dealer or a qualified workshop.

12 V battery
Procedure for starting the engine using another
battery or charging a discharged battery.
Lead-acid starter batteries
These batteries contain harmful
substances (sulphuric acid and lead).
They must be disposed of in accordance
with regulations and must never under any
circumstances be discarded with household
waste.
Take used remote control batteries and
vehicle batteries to a special collection point.
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, to avoid
any risk of explosion or fire.
Wash your hands afterwards.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery with
special technology and specifications.
It should only be replaced by a PEUGEOT
dealer or a qualified workshop.
Before doing any work
Immobilise the vehicle: apply the parking
brake, put the gearbox in neutral, then switch
off the ignition.
Check that all electrical equipment is switched
off.
Access to the battery

The battery is located under the bonnet.
To access them:
►

Open the bonnet using the interior release
lever

, then the exterior safety catch.

170
In the event of a breakdown
► Secure the bonnet stay.
► Remove the plastic cover on the (+) terminal.
The battery (-) terminal is not accessible.
A
remote earth point is located on the engine.
Starting using another
battery
If your vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24
V or higher battery booster.
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.
Switch off all electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►

Connect the red cable to the (+) terminal of
flat battery

A (at the metal elbow), then to the
(+) terminal of the backup battery
B or of the
booster.
►

Connect one end of the green or black cable
to the (-) terminal of the backup battery

B or of
the booster (or to an earth point on the assisting
vehicle).
►

Connect the other end of the green or black
cable to the earth point


C
.
►

Start the engine on the assisting vehicle 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 immediately, switch
off the ignition and wait a few moments before
trying again.
►

W
ait for it to return to idle.
►

Disconnect the jump leads in reverse order.
►


Refit the plastic cover to the (+) terminal, if
the vehicle has one.
►


Allow the engine to run for at least
30

minutes, with the vehicle stationary, so that
the battery reaches an adequate state of charge.
Drive cautiously during the first 30
minutes after starting the engine.
With an automatic gearbox, never try to
start the engine by pushing the vehicle.
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:
–

When using the vehicle mainly for short
journeys.
–


If the vehicle is to be taken off the road for
several weeks.
Contact a PEUGEOT

dealer or a qualified
workshop.

171
In the event of a breakdown
8Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
►

Switch the ignition off.
►


Switch off all electrical consumers (audio
system, lighting, wipers, etc.).


► 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.
► 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.
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components
connected to the Stop & Start system.
24V
12V
Never try to charge a frozen battery - risk
of explosion!
If the battery has frozen, have it checked by a
PEUGEOT 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.
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).
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:
►

Close all openings (doors, boot, windows,
roof).
►


Switch off all electrical consumers (audio
system, wipers, lighting, etc.).
►


Switch off the ignition and wait for 4
minutes.
At the battery, it is only necessary to disconnect
the (+) terminal.

172
In the event of a breakdown
Quick-release terminal clamp
Disconnecting the (+) terminal

► Depending on equipment, lift the plastic cover
on the (+) terminal.
►

Raise lever

A
fully to release clamp
B
.
►

Remove clamp

B
by lifting it off.
Reconnecting the (+) terminal

► Raise lever A fully.
► Refit the open clamp B on the (+) terminal.
► Push clamp B fully down.
► Lower lever A to lock clamp B.
►

Depending on equipment, lower the plastic
cover on the

(+) terminal.
Do not force the lever, as it will not lock
in place if the clamp is not positioned
correctly; start the procedure again.
Following reconnection
After reconnecting the battery, turn on the
ignition and wait 1 minute before starting the
engine, to enable the electronic systems to
initialise.
If minor problems nevertheless persist following
this operation, contact a PEUGEOT dealer or a
qualified workshop.
Referring to the relevant section, reinitialise
certain equipment:
–

Remote control key
.
–

Electric blind.
–


Electric windows.
–


Date and time.
–


Preset radio 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 exterior temperature and the
state of charge of the battery (up to about 8
hours).Towing the vehicle
