In the event of a breakdown
8Do not exceed the maximum authorised
speed of 50 mph (80 km/h) or the maximum
distance of 50 miles (80 km).
Driving with more than one "space-saver"
type spare wheel is prohibited.
Go to a PEUGEOT dealer or a qualified
workshop.
Have the tightening of the spare wheel's bolts
and its tyre pressure checked.
Have the punctured tyre examined. After
inspection, the technician will advise you on
whether the tyre can be repaired or if it must
be replaced.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Never look too closely at the light beam
of LED technology lamps - risk of serious
eye injury!


The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.

In the event of a breakdown
8Fuses
Changing a fuse
All work must be carried out only by a
PEUGEOT dealer or a qualified workshop
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
PEUGEOT dealer or a qualified workshop.
PEUGEOT 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 recommended by PEUGEOT and not
installed in accordance with its
recommendations, in particular when the
combined power consumption of all of the
additional equipment connected exceeds 10
milliamperes.
12 V battery/Accessory
batteries
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.
Dispose of used batteries at a designated
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.
Electronic control units/LED
technology headlamps
Never connect the negative jump lead to the
metal part of the electronic control units or at
the back of the headlamps.
Risk of destroying the electronic control units
and/or headlamps!
Connect to the remote earth point provided
for this purpose.
Frozen battery
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 could lead to a risk of
leakage of toxic and corrosive acid.
Automatic gearbox
Never try to start the engine by pushing
the vehicle.
Symbols
No sparks or naked flames, no smoking.
Always protect your eyes. Explosive gases can cause blindness and injury.
Keep the vehicle's battery out of the reach
of children.
The vehicle's battery contains sulphuric acid which can make you go blind or
cause severe burns.
For more information, refer to the
handbook.
Explosive gases can be present close to
the battery.

In the event of a breakdown
Accessing 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 with a quick-release
terminal.
(-) 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 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.
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.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions (e.g.
Stop & Start).
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. CarM an uals 2 .c o m

In the event of a breakdown
8Consult 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 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.

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).
