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
vest, etc.) according to the legislation in force in
the country of driving.

These tools are specific to the vehicle and may vary according to the level of
equipment.
Do not use them for any other purpose.
The jack must only be used to change a wheel with a damaged or punctured tyre.
Do not use any jack other than the one
supplied with the vehicle.
If the vehicle does not have its original jack,
contact a CITROËN dealer or a qualified
workshop to obtain the one that was intended
by the manufacturer.
The jack meets European standards, as
defined in the Machinery Directive 2006/42/
CE.
The jack does not require any maintenance.
Temporary puncture repair kit
Scan the QR Code on page 3 to view
explanatory videos.
Made up of a compressor and a sealant
cartridge, it allows you to carry out a temporary
repair of the tyre so that you can drive to the
nearest garage.
It is designed to repair most punctures located
on the tyre tread.
For more information on the Tool kit,
refer to the corresponding section.

142
In the event of a breakdown
The tyre inflation pressures are given on this label.


► Switch on the ignition.

► Switch on the compressor by moving the switch to position " I" until the tyre pressure
reaches 2 bar. The sealant product is injected
under pressure into the tyre; do not disconnect
the pipe from the valve during this operation (risk
of blowback).
If after approximately 7 minutes, the
pressure of 2 bar is not reached, this
indicates that the tyre is not repairable;
contact a CITROËN dealer or a qualified
workshop for assistance.
► Move the switch to position "O".► Disconnect the compressor's electric plug from the vehicle's 12 V socket.► Refit the cap on the valve.► Remove the kit.► Remove and store the bottle of sealant.
The sealant product is harmful if swallowed and causes irritation to the
eyes.
Keep this product out of the reach of children.
The use-by date of the fluid is marked on the
bottle.
After use, do not discard the bottle in
standard waste, take it to a CITROËN dealer
or an authorised waste disposal site.
Do not forget to obtain a new bottle of
sealant, available from a CITROËN dealer or
a qualified workshop.


► Drive immediately for approximately 3 miles (5 kilometres) at reduced speed (between
12 and 37 mph (20 and 60 km/h)) to plug the puncture.► Stop to check the repair and the tyre
pressure using the kit.
With a tyre repaired using this type of kit, do not exceed a speed of 50 mph (80 km/h) and do not drive more than 125 miles (200 km).Contact a CITROËN dealer or a qualified
workshop to have the tyre changed.
Checking / 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 on the ignition.
Only the 12 V socket located at the front
of the vehicle can be used to power the
compressor .

143
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.
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.
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.

146
In the event of a breakdown
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.
