2016 Citroen DS4 Valve

Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres.Driving with under-inflated tyres
increases fuel consumption.The tyre pressures for your vehicle
can be found on the tyre pressure
label (see the "Identification markings"
section).
The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Other wise, add 0.3 bar to the values
indicated on the label.
This system does not avoid the need
to check the tyre pressures regularly
(including the spare wheel) and before
a long journey.
Driving with under-inflated tyres
adversely affects road holding,
extends braking distances and causes
premature tyre wear, particularly under
arduous conditions (vehicle loaded,
high speed, long journey).
The tyre under-inflation detection system is an
aid to driving which does not replace the need
for vigilance on the part of the driver.

pressure using the kit.
Do not start the compressor before
connecting the white pipe to the tyre
valve: the sealant product would be
expelled through the pipe.
Tyre under-inflation 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.
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.

2. Inflation
F 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).

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.

Checking tyre pressures /
inflating accessories
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. You can also use the compressor, without
injecting any product, to:
-
c heck or adjust the pressure of your tyres,
