Description of the kit
The speed limit sticker H must be affixed to the vehicle's steering wheel to remind you that a wheel is in temporary use.
Do not exceed a speed of 50 mph (80 km/h) when driving with a tyre repaired using this type of kit.

In the event of a breakdown
 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 electric plug to the vehicle's 12 V socket.  Start the vehicle and leave the engine running.
Take care, this product is harmful if swallowed and causes irritation to the eyes. Keep this product out of the reach of children.
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 the switch B to position "I" until the tyre pressure reaches 2.0 bars. The sealant is injected into the tyre under pressure; do not disconnect the pipe from the valve during this operation (risk of splashing).
If after around 5 to 7 minutes the pressure is not attained, this indicates that the tyre is not repairable; contact a CITROËN dealer or a qualified workshop for assistance.

As soon as possible, go to a CITROËN dealer or a qualified workshop. You must inform the technician that you have used this kit. After inspection, the technician will advise you on whether the tyre can be repaired or if it must be replaced.
 Remove the kit and screw the cap back on the white pipe. Take care to avoid staining your vehicle with traces of fluid. Keep the kit to hand.  Drive immediately for approximately three miles (five 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.

Removing the pipe and cartridge
 Turn the pipe assembly 2 to the left until it contacts the unit.  Disconnect the union 1 from the cartridge by turning it a quarter turn anti-clockwise.  Extract the pipe assembly 2 , then disconnect the union 3 from the air delivery pipe by turning it a quarter turn anti-clockwise.  Remove the pipe assembly 2 .  Support the compressor vertically.  Unscrew the cartridge 4 from the bottom. To fit the new cartridge and new pipe, carry out these operations in reverse order.
Beware of discharges of fluid. The expiry date of the fluid is indicated on the cartridge. The sealant cartridge is designed for single use; even if only partly used, it must be replaced. After use, do not discard the cartridge into the environment, take it to an authorised waste disposal site or a CITROËN dealer. Do not forget to obtain a new sealant cartridge, available from CITROËN dealers or from a qualified workshop.
 Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to deflate: switch B in position "O" and press button C ), in accordance with the vehicle's tyre pressure label (located on the left-hand door aperture). A loss of pressure indicates that the puncture has not been fully plugged; contact a CITROËN dealer or qualified workshop for assistance.  Remove and stow the kit.  Drive at reduced speed (50 mph [80 km/h]
max) limiting the distance travelled to approximately 120 miles (200 km).

Checking / adjusting tyre pressures
You can also use the compressor without injecting any product, to check and if necessary adjust your tyre pressures.
 Turn the selector A to the "Air" position.  Uncoil the white pipe G fully.
 Connect the compressor's electrical connector to the vehicle's 12 V socket.  Start the vehicle and let the engine run.  Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to deflate: switch B in position "O" and press button C ), according to the vehicle's tyre pressure label.  Remove the kit then 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 Under-inflation detection , refer to the corresponding section.
 Connect the pipe to the tyre valve.
