Repair procedure
Do not remove any foreign bodies (e.g.
nail, screw) which have penetrated into
the tyre.
►

Park the vehicle without obstructing traffic
and apply the parking brake.
►


Follow the safety instructions (hazard
warning lamps, warning triangle, high visibility
jacket, etc.) according to the legislation in force
in the country in which you are driving.
►


Switch the ignition off.
►


Uncoil
the pipe stowed under the compressor.


► Connect the pipe from the compressor to the
bottle of sealant.


► Turn the bottle of sealant over and secure it
in the notch provided on the compressor.
►

Remove the valve cap from the tyre to be
repaired, and place it in a clean place.

141
In the event of a breakdown
8Checking/adjusting tyre
pressures
The compressor can be used, without injecting
sealant, to check and, if necessary, adjust the
tyre pressures.
►

Remove the valve cap from the tyre and keep
it in a clean place.
►


Uncoil
the pipe stowed under the compressor.
►

Screw the pipe onto the valve and tighten
firmly

.
►

Check that the compressor switch is in
position " O

".
►

Fully uncoil the electric cable stowed under
the compressor

.
►

Connect the compressor's electric plug to the
vehicle's 12

V socket.
►

Switch the ignition on.
►


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.
►


Refit the cap on the valve.
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.
Spare wheel
Scan the QR Code on page 3 to view
explanatory videos.
For more information on the Tool kit,
refer to the corresponding section.
Accessing the spare wheel
The spare wheel is stored in the boot, under the
floor.
To access the spare wheel, first refer to the
Tool
kit
section.
Depending on version, the spare wheel
may be a standard steel or 'space-saver'
wheel.
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

.
►

T
ake 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 set to automatic mode, and switch
off the ignition.

142
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.
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.


– 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
easily admit the spare (not punctured) wheel.
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 on the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
injury!

the boot; use a cover to protect the inside of
the boot.
Fitting a wheel
Fitting a steel or "space-saver" type
spare wheel
If the vehicle is fitted with alloy wheels, the
washers A do not make contact with the steel
or "space-saver" type spare wheel. The wheel

In the event of a breakdown
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
Opening the bonnet/Accessing the
bulbs
Proceed with caution when the engine is hot -
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:
– Front foglamps.
– Daytime running lamps/sidelamps.
– Dipped beam headlamps.
– Main beam headlamps.
– Direction indicator side repeaters.
– Third brake lamp.
– Number plate lamps.
Putting the spare wheel
back in place
The punctured wheel cannot be put
under the boot 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.
►


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

Stow the tools in the bag or storage box
(depending on equipment).
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) or the maximum
distance of 50 miles (80 km).
Driving with more than one "space-saver"
type spare wheel is prohibited.
Visit 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.
