In the event of a breakdown
8The tyre inflation pressures are given on this label.


► Start the compressor by placing the switch at position " I" and adjust the pressure to the value
shown on the vehicle's tyre pressure label. To
deflate: press the black button located on the
compressor pipe, near the valve connection.
If after 7 minutes the pressure of 2 bar is
not reached, the tyre is damaged;
contact a CITROËN dealer or a qualified
workshop for assistance.
► Once the correct pressure is reached, put the switch in position " O".► Remove the kit and stow it.
Should the pressure of one or more tyres
be adjusted, it is necessary to reinitialise
the under-inflation detection system.
For more information on Tyre under-inflation
detection, refer to the corresponding section.

Access to the spare wheel

The spare wheel is installed in the boot, under
the floor.
Removing the spare wheel

► Unclip and remove the tool storage box or remove the polystyrene cover (depending on
version).
► Slacken the central nut.► Remove the fastening device (nut and bolt).► Lift the spare wheel towards you from the rear.► Take the wheel out of the boot.
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 programmed to be in automatic
mode, and switch off the ignition.

144
In the event of a breakdown

► Remove the bolts and store them in a clean place.► Remove the wheel.
Stowing the damaged wheel► To stow an alloy wheel , first remove
the wheel trim from the centre of the wheel so
that the fastening device (nut and bolt) can be
put in place.
► In the case of a "space saver" type
spare wheel, the damaged wheel cannot be
stowed under the floor. It must be placed in
the boot; use a cover to protect the inside of
the boot.

to lock the wheels, apply the parking brake,
unless it is programmed to be in automatic
mode, and switch off the ignition.
Check for the fixed illumination of the parking
brake indicator lamps in the instrument panel.
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.


– If the vehicle has steel wheels, remove the wheel trim.– If the vehicle has alloy wheels, remove the central bolt cover using tool 7.– If the vehicle is so equipped, fit security bolt socket 2 to wheelbrace 5 to slacken the security
bolt.
– Slacken the other bolts using the wheelbrace 5 only.

► 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.


► Extend jack 6 until its head comes into contact with jacking point A or B; contact area A
or B on the vehicle must be properly inserted
into the central part of the head of the jack.
► Raise the vehicle until there is sufficient space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area of the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!

Fitting a wheel

Fitting a steel or ‘space-saver’ type
spare wheel
If the vehicle is equipped with alloy wheels,
the washers do not make contact with the
steel or ‘space-saver’ type spare wheel. The
wheel is secured by the conical surface of
each bolt.


► Fit the wheel on the hub.► Screw in the bolts by hand as far as possible.► Pre-tighten the security bolt using the wheelbrace 5 equipped with a security socket 2.► Pre-tighten the other bolts using the wheelbrace 5 only.

► Lower the vehicle again fully .► Fold jack 6 and remove it.

► Tighten the security bolt using the wheelbrace 5 equipped with a security socket 2.► Tighten the other bolts using the wheelbrace 5 only.► Refit the bolt covers to each of the bolts (depending on equipment).► Store the tools.

Refitting the lamp unitsPerform 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.
Light-emitting diode (LED)
headlamps and lamps
Depending on version, the affected types of
headlamps / lamps are:
– Daytime running lamps / sidelamps.– Direction indicator side repeaters.– Third brake lamp.– Number plate lamps.
Putting the spare wheel
back in place
The punctured wheel cannot be placed in
the boot under the floor.


► 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.► Tighten the central nut sufficiently to retain the wheel correctly.► Put the tool box back in place in the middle of the wheel and clip it in place.► Clip the tool storage box or put the polystyrene cover back in place (depending on
version).
If there is no wheel in the well, the
fastening device (nut and bolt) cannot be
refitted.
After changing a 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.
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.

failed.
► Turn the bulb holder a eighth of a turn anti-clockwise and remove it.► Remove the bulb and replace it.
Amber coloured bulbs must be replaced by bulbs with identical specifications and
colour.
Dipped beam headlamps

► Remove the protective cover by unscrewing it.► Disconnect the bulb connector .► Pull out the bulb and replace it.
