► Put the spare wheel back in place in its
housing.
►

Slacken the nut on the bolt by a few turns.
►


Position the fastening device (nut and bolt) in
the middle of the wheel.
►


T
ighten the central nut sufficiently to retain
the wheel correctly.

Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does
not obstruct traffic: the ground must be level,
stable and non-slippery.
With a manual gearbox, engage first gear
to lock the wheels, apply the parking brake,
unless it is set to automatic mode, and switch
off the ignition.
With an automatic gearbox, select mode P
to lock the wheels, apply the parking brake,
unless it is set to automatic mode, and switch
off the ignition.
Check that the parking brake indicator lamps
on the instrument panel are on fixed.
The occupants must get out of the vehicle
and wait where they are safe.
If necessary, place a chock under the wheel
diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel , refit the wheel
trim, starting by placing its aperture in line
with the valve and then pushing it into place
all round its edge with the palm of your hand.




► To remove the wheel bolt cover on each of
the bolts, use tool 7 (alloy wheels).
►

Fit security socket
2 on wheelbrace

► Place the foot of jack 6 on the ground and
ensure that it is directly below the front A or
rear
B jacking point on the underbody, whichever
is closest to the wheel to be changed.

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, Adaptive Cruise Control,
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.
Go to a CITROËN 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.
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.
Halogen bulbs
To ensure good quality lighting, check
that the bulb is correctly positioned in its
housing.
Light-emitting diode (LED)
headlamps and lamps
Depending on version, the affected types of
headlamps/lamps are:
–

Full LED technology headlamps.
–


Daytime running lamps/sidelamps.
–


Direction indicator side repeaters.
–


Direction indicators.
–


Side spotlamps.
–


3D rear lamps.
–


Third brake lamp.
–


Number plate lamps.
If you need to replace this type of bulb,
you must contact a CITROËN dealer or a
qualified workshop.
Do not touch the "Full LED" technology
headlamps or lamps - risk of electrocution!

With an automatic gearbox, never try to
start the engine by pushing the vehicle.
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.
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 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.
►


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.

196
In the event of a breakdown
► At the end of the charging operation, switch
off charger B
before disconnecting the cables
from battery A.
If this label is present, use only a 12 V
charger to avoid causing irreversible
damage to the electrical components
connected to the Stop & Start system.
24V
12V
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.

In this case, the system will only be
available again after a continuous period of
immobilisation of the vehicle, a period which
depends on the exterior temperature and the
state of charge of the battery (up to about 8
hours).
Accessory battery (Rechargeable hybrid)
The rechargeable hybrid system has two
accessory batteries: one at the front and one at
the rear of the vehicle.
The batteries contain harmful substances (sulphuric acid and lead).
