In the event of a breakdown
8After changing a wheel
Store the punctured wheel in the boot or,
depending on version, remove the central cover
first to store it beneath the floor in place of the
spare wheel.


With a "space-saver" type spare wheel
Deactivate certain driving aid functions
(Active Safety Brake, etc.).
Do not exceed the maximum authorised
speed of 50 mph (80
km/h).
Driving with more than one “space-saver”
type spare wheel is prohibited.
Visit a CITROËN dealer or a qualified
workshop as soon as possible to have
the tightness of the bolts and the pressure of
the spare wheel 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.
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.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Opening the bonnet / Accessing the
bulbs
With the engine warm, proceed with caution -
risk of burns!
Take care with objects or clothing that could
be caught in the blades of the cooling fan -
risk of strangulation!
Halogen bulbs (Hx)
To ensure good quality lighting, check
that the bulb is correctly positioned in its
housing.
After changing a bulb
To refit, carry out the fitting operations in
reverse order.
Close the protective cover very carefully to
guarantee the sealing of the lamps.
Light-emitting diode (LED)
headlamps and lamps
Depending on version, the affected types of
headlamps / lamps are:

In the event of a breakdown

For access to the (+) terminal:
► release the bonnet using the interior lever ,
then the exterior safety catch,
►

lift the bonnet, then fix it in place with its stay
.
(+) Positive terminal.
It has a quick-release clamp.
(-) Negative terminal.
The battery (-) terminal is not accessible, use the
engine mounting.
Starting using another
battery
When your vehicle's battery is discharged, the
engine can be started using a backup battery
(external or from another vehicle) and jump
leads or a battery booster.
Never try to start the engine by
connecting a battery charger.
Never use a 24 V or higher battery booster.
Check beforehand that the back-up 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 the electrical consumers on both
vehicles (audio system, wipers, lighting, etc.).
Make sure that the jump leads are not close
to moving parts of the engine (fan, belts, etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if
your vehicle has one.
►

Connect the red cable to the positive terminal
(+) of flat battery A

(at the metal elbow) then to
the positive terminal (+) of back-up battery B or
the booster.
►

Connect one end of the green or black cable
to the negative terminal (-) of back-up battery B


or the booster (or the earth point on the other
vehicle).
►
Connect the other end of the green or black
cable to earth point C

on the broken down
vehicle.
►

Start the engine of the vehicle with the good
battery 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 straight away

, switch
off the ignition and wait a few moments before
trying again.
►

W
ait until the engine returns to idle then
disconnect the jump lead cables in the reverse
order.
►

Refit the plastic cover to the (+) terminal, if
your vehicle has one.
►


Allow the engine to run for at least 30
minutes, by driving or with the vehicle stationary

,
so that the battery reaches an adequate state of
charge.
Some functions, including Stop & Start,
are not available if the battery is not
sufficiently charged.
Charging the battery using a
battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.

123
In the event of a breakdown
8In 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 CITROËN 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.).


► 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
CITROËN 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.
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.
