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.

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).

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.
