CITROËN DS4 Owner's Handbook Manual page 248

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).
Tyre under-infl ation detection
If the vehicle is fitted with tyre under-
inflation detection, the under-inflation
warning lamp will remain on after the
wheel has been repaired until the
system is reinitialised by a CITROËN
dealer or a qualified workshop.
Do not start the compressor before
connecting the white pipe to the tyre
valve: the sealant product would be
expelled through the pipe.
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.
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 15 and 35 mph [20 and
60 km/h]), to plug the puncture.
Stop to check the repair and the tyre
pressure using the kit.
