In the event of a breakdown
8► Tighten the spare wheel fixing screw by a few
turns.
After changing a wheel
The temporary spare wheel is only intended for temporary emergency use,
until the conventional wheel can be repaired
or replaced.
Continuous use of this spare can result in tire
failure and loss of control. Always observe
these precautions when using this spare:
–

Y

our vehicle will respond differently with
this temporary spare.
–

Do not exceed 80 km/h speed.
–


Replace this spare with a standard tire and
wheel as soon as possible.
–


Use of this spare will reduce ground
clearance.
–


Set the specified tire pressure indicated
on the tire information label located on the
driver's door lock pillar

.
–

Do not use tire chains on the temporary
spare. If you must use tire chains, rearrange
the wheels so standard tires and wheels are
fitted to the front axle.
–


The temporary spare wheel has a much
shorter tread life than the conventional

wheels
on your vehicle. Replace the tire as soon as
possible as the tread wear indicator appears.
The inflation pressure of the temporary spare
wheel should be checked at least monthly. At
the same time, check that the tire is stored
securely. If it is not, tighten it.
Note that two or more temporary spare
wheels should not be used on one vehicle
simultaneously.
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.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
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.

Changing a fuse
Access to the tools

The puller is located inside the engine fuse box.
► Open the bonnet.
►

Disengage the cover completely
.
►

T
ake the puller from its housing.
Changing a fuse
Before changing a fuse:
► Identify the cause of the fault and fix it.
►

Switch off all power consumption.
►


Identify the defective fuse using the current
allocation tables and diagrams.
T

o replace a fuse, it is essential to:
►

Use the special puller to extract the fuse
from its housing and check the condition of its
filament.
► Always replace the failed fuse with a fuse of
the same rating (same colour); use of a different
rating may cause malfunctions - risk of fire!
If the fault recurs soon after replacing a fuse,
have the electrical system checked by a
CITROËN dealer
.
The fuse allocation tables and the corresponding diagrams are available
from a CITROËN dealer.
The replacement of a fuse not shown in the allocation tables may cause a serious
malfunction of the vehicle. Contact a
CITROËN dealer.

12 V battery
Lead-acid starter batteries
These batteries contain harmful
substances (sulphuric acid and lead).
They must be disposed at authorized dealer/
battery shop in accordance with regulations
and must never under any circumstances be
discarded with household waste.
Take used remote control batteries and
vehicle batteries to a special collection point.
Protect your eyes and face before
handling the battery.
Use goggles and gloves while working with
the battery. Diluted sulphuric acid spilled from
battery can cause blindness or severe burns.
Flush eyes or body with ample water and get
medical care immediately if suffered.
Keep batteries out of the reach of children.
All operations on the battery must be carried
out in a well ventilated area and away from
naked flames and sources of sparks, so as to
avoid any risk of explosion or fire.
Wash your hands afterwards.
If the battery fails (after warranty
coverage), replace it with a battery of the
same specification as the one used in the
vehicle.
Access to the battery
The battery is located under the bonnet.
Naturally Aspirated engine version

(+) Positive terminal.
(-) Negative terminal.
Turbo engine version

(+) Positive terminal.
(-) Negative terminal.
A remote earth point is located near the battery.
Starting using another
battery
If the vehicle's battery is flat/drain/discharged,
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

57
In the event of a breakdown
8at 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.
During jump start, extra care should be taken
to ensure right terminals are connected. If
terminal connections are reversed, it will
lead to failure of alternator & other electrical,
electronic components.
Never power electrical or electronic
components directly from battery terminals
as it will lead to poor battery charging, poor
performance of components and battery
sensor malfunction, which will impact fuel
economy. For Naturally Aspirated engine version

► Lift the cover on the (+) terminal, if the vehicle
has one.
►
Connect the red cable to the (+) terminal
of flat battery

A, 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 (-) terminal of flat battery

A.
►

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:
first remove (-) terminal then (+) terminal.
► Refit the 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.
For Turbo engine version

The negative cable must be connected to the car ground (not to the battery
negative terminal) so that the battery sensor
can detect all charging and discharging
currents.
►

Lift
the 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
