Under-inflation detection
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
Driving with under-inflated tyres
increases fuel consumption. Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for
1
hour or after a journey of less than
6
miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the pressures
shown on the label.

Under-inflation alertReinitialisation
This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and, depending on
equipment, the display of a message. It is necessary to reinitialise the system every
time one or more tyre pressures are adjusted,
and after changing one or more wheels.

F

I
n the event of a puncture, use the
temporary puncture repair kit or the spare
wheel (depending on equipment).
The loss of pressure detected does not
always cause visible bulging of the tyre.
Do not satisfy yourself with just a visual
check. The alert is maintained until the system
is reinitialised.
Snow chains
The system does not have to be
reinitialised after fitting or removing
snow chains. Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation alert can only
be relied on if the reinitialisation of
the system has been done with the
pressures in the four tyres correctly
adjusted.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.

For more information on snow chains, contact a
CITROËN dealer or a qualified workshop. Use only chains designed to be fitted the type
of wheel on your vehicle:
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking. The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of your
vehicle.
F

F

provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised. Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

Important: if your vehicle's AdBlue®
tank is completely empty - which is
confirmed by the alert messages and
the impossibility of starting the engine,
you must add at least 3.8 litres of fluid. Important:
when topping-up after
running out of AdBlue®, signalled
by the message "Top-up AdBlue:
Starting prevented", you must wait
for approximately 5 minutes before
switching on the ignition, without
opening the driver's door, unlocking
the vehicle, placing the key of the
"Keyless Entr y and Star ting" system
inside the vehicle or inser ting the
electronic key in the reader.
Switch on the ignition, wait for
10

seconds, then start the engine.
If any fluid is spilt or splashed, wash
immediately with cold water or wipe with
a damp cloth.
If the fluid has crystallised, clean it off
using a sponge and hot water.
