Get In the event of a breakdown -> 12 V battery / Accessory battery Guide for Peugeot 2008 SUV Second Generation (2019-2025)

In the event of a breakdown

Precautions before working on the

accessory battery

Select mode P, switch oﬀ the ignition, check

that the instrument panel is oﬀ and that the

vehicle is not being charged.

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.

12 V battery / Accessory

battery

Procedure for starting the engine using another

battery or for charging a discharged battery.

Lead-acid starter batteries

Jump-starting another vehicle

Do not use the accessory battery to

jump-start another vehicle or to charge

another vehicle's battery.

Never start the engine by connecting a

battery charger.

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.

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.

Accessing the battery

The battery is located under the bonnet.

Take used remote control batteries and

vehicle batteries to a special collection point.

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.).

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.

Do not disconnect the (+) terminal while the

engine is running.

For access to the (+) terminal:

► Release the bonnet by pulling the internal

release lever, then the external safety catch.

► Raise the bonnet.

Wash your hands afterwards.

Electric motor

(+) Positive terminal.

Flat accessory battery

This terminal has a quick-release clamp.

(-) Negative terminal.

It is no longer possible to start the motor

or recharge the traction battery.

As the battery's negative terminal is not

accessible, a remote earth point is located facing

the battery.

173

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.

Never reverse polarities.

Driving immediately without having

reached a suﬃcient level of charge may

aﬀect some of the vehicle's functions.

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.

► 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.

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.

Consult a PEUGEOT dealer or a qualiﬁed

workshop.

► 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,

If the engine does not start immediately, switch

oﬀ the ignition and wait a few moments before

trying again.

To charge the vehicle's battery yourself,

use only a charger compatible with

lead-acid batteries with a nominal voltage of

12 V.

► 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.

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

on the vehicle.

174

In the event of a breakdown

Reconnecting the (+) terminal

► At the end of the charging operation, switch

oﬀ charger B before disconnecting the cables

from battery A.

► 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.

If this label is present, use only a 12 V

charger to avoid causing irreversible

damage to the electrical components.

Quick-release terminal clamp

Disconnecting the (+) terminal

24V

12V

► Raise lever A fully.

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

► Push clamp B fully down.

Never try to charge a frozen battery - risk

of explosion!

► Lower lever A to lock clamp B.

► Depending on equipment, lower the plastic

cover on the (+) terminal.

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.

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.

Disconnecting the battery

Following reconnection

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.

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.

Before disconnecting the battery:

► Close all openings (doors, boot, windows,

roof).

175

In the event of a breakdown

Referring to the relevant section, reinitialise

certain equipment:

– Remote control key or electronic key

(depending on version).

– Sunroof.

– Electric windows.

– Date and time.

– Preset radio stations.

– Not possible to put the gearbox into neutral,

unlock the steering, or release the parking

brake.

– Not possible to tow a vehicle with an

automatic gearbox, with the engine running.

– Towing with only two wheels on the ground.

– Four-wheel drive vehicle.

Towing the vehicle

General recommendations

Observe the legislation in force in the

country where you are driving.

Ensure that the weight of the towing vehicle is

higher than that of the towed vehicle.

The driver must remain at the wheel of the

towed vehicle and must have a valid driving

licence.

When towing a vehicle with all four wheels on

the ground, always use an approved towing

arm; rope and straps are prohibited.

The towing vehicle must move oﬀ gently.

When the vehicle is towed with its engine

oﬀ, there is no longer braking and steering

assistance.

– No approved towbar available.

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).

Before towing the vehicle, it is essential

to put the vehicle in free-wheeling mode.

For more information on Free-wheeling, refer

to the corresponding section.

Electric motor

An electric vehicle cannot under any

circumstances be used to tow another

vehicle.

A professional towing service must be

called if:

However, it may be used, for example, to exit

a rut.

– Broken down on a motorway or main road.
