In the event of a breakdown

The replacement of a fuse by a third party

could cause a serious malfunction of the

vehicle.

Installing electrical accessories

The vehicle's electrical system is

designed to operate with standard or optional

equipment.

Before fitting other electrical equipment or

accessories to your vehicle, contact a dealer or

a qualified workshop.

►ꢀ Using the opening tool, unclip the cover of

the access flap on the rear screw thread of the

towing eye, then pull it towards you.

►ꢀ Disconnect the harness.

The Manufacturer accepts no

responsibility for the cost incurred in

repairing the vehicle or for rectifying

malfunctions resulting from the installation of

accessories not supplied or not approved by it

and not installed in accordance with its

specifications, in particular when the

combined power consumption of all of the

additional equipment connected exceeds 10

milliamperes.

For each lamp:

►ꢀ Turn the bulb holder a quarter turn anti-

clockwise and remove it.

In the event of a breakdown

Lead-acid starter batteries

For access to the (+) terminal:

►ꢀ Release the bonnet by pulling the internal

release lever, then the external safety catch.

►ꢀ Raise the bonnet.

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.

(+) 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.

Take used remote control batteries and vehicle

batteries to a special collection point.

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

vehicle has one.

Protect your eyes and face before

handling the battery.

Starting using another battery

If the 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.

►ꢀ 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).

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.

Never start the engine by connecting a

battery charger.

Wash your hands afterwards.

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.

Accessing the battery

The battery is located under the bonnet.

►ꢀ 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.

Switch off all electricity-consuming equipment

on both vehicles (audio system, wipers,

lighting, etc.).

If the engine does not start immediately, switch

off the ignition and wait a few moments before

trying again.

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.

►ꢀ Wait 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.

192

In the event of a breakdown

►ꢀ Allow the engine to run for at least 30 minutes,

with the vehicle stationary, so that the battery

reaches an adequate state of charge.

Follow the instructions provided by the

manufacturer of the charger.

►ꢀ At the end of the charging operation, switch

off charger B before disconnecting the cables

from battery A.

Never reverse polarities.

Driving immediately without having

reached a sufficient level of charge may

affect some of the vehicle's functionalities.

If this label is present, use only a 12 V

charger to avoid causing irreversible

damage to the electrical components.

It is not necessary to disconnect the

battery.

►ꢀ Switch the ignition off.

►ꢀ Switch off all electrical consumers (audio

system, lighting, wipers, etc.).

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.

Never try to charge a frozen battery - risk

of explosion!

If the battery has frozen, have it checked by

a 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.

In some circumstances, it may be necessary to

charge the battery:

– When using the vehicle mainly for short

journeys.

►ꢀ Switch off charger B before connecting

the cables to the battery, so as to avoid any

dangerous sparks.

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

several weeks.

Some functions, including Stop & Start,

are not available if the battery is not

sufficiently charged.

Contact a dealer or a qualified workshop.

►ꢀ Ensure that the charger cables are in good

condition.

To charge the vehicle's battery yourself,

use only a charger compatible with

lead-acid batteries with a nominal voltage of

12 V.

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

vehicle has one.

Disconnecting the battery

►ꢀ Connect the cables of charger B as follows:

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

of battery A,

In order to maintain an adequate state of

charge for starting the engine, we recommend

disconnecting the battery if the vehicle is to be

unused for an extended period.

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

the vehicle.

193

In the event of a breakdown

Before disconnecting the battery:

►ꢀ Close all openings (doors, boot, windows,

roof).

Reconnecting the (+) terminal

Referring to the relevant section, reinitialise

certain equipment:

– Electronic key.

►ꢀ Switch off all electricity-consuming devices

(audio system, wipers, lamps, etc.).

►ꢀ Switch off the ignition and wait for 4 minutes.

After accessing the battery, it is only necessary to

disconnect the (+) terminal.

– Sunroof and electric blind.

– Electric windows.

– Date and time.

– Preset radio stations.

After reconnecting the battery, the

message "Collision risk detection system

fault" is displayed on the instrument panel

when the ignition is switched on. This

operation is perfectly normal. The message

will disappear while driving.

Quick-release terminal clamp

Disconnecting the (+) terminal

►ꢀ Raise lever A fully.

►ꢀ Refit 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.

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).

Do not force the lever when pressing on it,

as if the clamp is not positioned correctly,

locking will then not be possible. Start the

procedure again.

►ꢀ 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.

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.

Accessory battery

(Rechargeable hybrid)

The rechargeable hybrid system has two

accessory batteries: one at the front and one at

the rear of the vehicle.

If minor problems nevertheless persist following

this operation, contact a dealer or a qualified

workshop.
