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.
Access to the battery
The battery is located under the bonnet.

For access to the (+) terminal:
► Release the bonnet by pulling the internal
release lever , then the external safety catch.
►

Raise the bonnet.
(+)

Positive terminal.
This terminal has a quick-release clamp.
(-) Negative terminal.
As the battery's negative terminal is not
accessible, a remote earth point is located near
the battery.
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.

190
In the event of a breakdown
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:
–

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.
To charge the vehicle's battery yourself, use only a charger compatible with
lead-acid batteries with a nominal voltage of
12

V.
Follow the instructions provided by the
manufacturer of the charger.
Never reverse polarities.
It is not necessary to disconnect the
battery.
►

Switch off the ignition.
►


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

191
In the event of a breakdown
8

► 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.

24v 12v
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.
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.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
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.
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.

192
In the event of a breakdown
► 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 locking will be
impossible if the clamp is not positioned
correctly; start the procedure again.
After 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, reset certain
equipment:
–

Electronic key
.
–

Sunroof and electric sun blind.
–


Electric windows.
–


Date and time.
–


Preset radio stations.
After reconnection of the battery, the “Collision risk detection system fault”
message is displayed on the instrument panel
when the ignition is switched on. This
operation is perfectly normal. The message
will disappear while driving.
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 with the
vehicle immobilised, the duration of which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
Accessories batteries (Hybrid)
The hybrid system has two accessory batteries:
one at the front and one at the rear of the
vehicle.
The batteries contain harmful substances (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.
Protect your eyes and face before
handling batteries.
All operations on the batteries 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.
For the replacement of batteries, contact a
PEUGEOT dealer or a qualified workshop.
