bonnet, you must switch off the ignition, check
that the READY indicator lamp is off on the
instrument panel and disconnect the charging
nozzle if it is plugged in.
The location of the interior bonnet release lever prevents the bonnet being
opened when the left-hand front door is

Access to the kit
This kit is stowed in a tool box.
For more information on the Tool box,
refer to the corresponding section.
List of tools
These tools are specific to the vehicle and may
vary according to the level of equipment. Do not
use them for any other purpose.


1. 12 V compressor.
Contains a sealant cartridge for the
temporary repair of a tyre and can also be
used for adjusting tyre pressures.
2. Towing eye.
For more information on Towing, please
refer to the corresponding section.
Tyre inflation pressures are indicated on this label.
For more information on Identification
markings, particularly this label, refer to the
corresponding section.
Composition of the kit

In the event of a breakdown

E.Compartment housing a cable with an
adaptor for a 12
V socket.
F. Sealant cartridge.
G. White pipe with cap for repair and inflation.
H. Speed limit sticker.
The vehicle's electrical system allows the
connection of the compressor for long
enough to inflate a tyre after a puncture
repair.
Only use the two 12 V sockets, located at the
front, to connect your compressor.
Repair and sealing
procedure
► Park the vehicle without obstructing any
traffic and apply the parking brake.
►

Follow the safety instructions (hazard
warning lamps, warning triangle, wearing high
visibility vest, etc.) according to the legislation in
force in the country where you are driving.
► Switch off the ignition.► Turn the selector A to the "Repair"
position.
►

Check that switch
B is in position " O".
Avoid removing any foreign bodies which
have penetrated the tyre.


► Uncoil the white pipe G fully.
► Unscrew the cap from the white pipe.
►

Connect the white pipe to the valve of the
tyre to be repaired.
►


Connect the compressor's electrical plug to
the vehicle's 12 V socket.
► Affix the speed li mit sticker.
The speed limit sticker must be secured
to the interior of the vehicle in the driver's
field of vision, to remind you that a wheel is in
temporary use.
► Start the vehicle and leave the engine
running.
Do not start the compressor before
connecting the white pipe to the tyre
valve: the sealant product would be expelled
through the pipe.
►

Switch on the compressor by moving switch
B

to position I until the tyre pressure reaches
2.0 bars. 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 seven minutes this
pressure is not reached, this indicates
that the tyre is not repairable; contact a
PEUGEOT dealer or a qualified workshop for
assistance.
►

Remove the kit and screw the cap back on
the white pipe.

Take care to avoid contaminating
the vehicle with traces of fluid. Keep the kit to
hand.
Take care, 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 PEUGEOT dealer
or an authorised waste disposal site.
