Under-inflation detection
The tyre under-inflation detection system
is a driving aid which does not replace the
need for vigilance on the part of the driver.This system does not relieve you of
the monthly check of the tyre inflation
pressures (including the spare) and before
a


long journey.
Driving with under-inflated tyres impairs
handling, extends braking distances and
causes premature tyre wear, particularly
in adverse conditions (heavy loads, high
speeds, long journeys).
Driving with under-inflated tyres
increases fuel consumption.
The tyre pressure specifications for your
vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked 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 values
indicated on the label.
For more information on Identification
markings , including in particular the tyre
pressure label, refer to the corresponding
section. The tyre pressure measurement unit can be
configured with the MODE
button: in the "Tyre
pressure measurement" menu, select "psi/bar/
k Pa".
For more information on Vehicle
configuration , refer to the corresponding
section.
Under-inflation warning
This warning is indicated by
continuous illumination of this lamp,
an audible signal and, depending on
the equipment installed, a message
displayed on the screen.
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 as soon as it
detects a

drop in the inflation pressure of one
or more tyres. In the event of a
problem with one of the tyres,
depending on equipment the symbol or the
message appears to identify it.

Temporary puncture
repair kit
This temporary puncture repair kit is kept
in a bag and stowed in one of the front door
pockets.
It consists of:
-

a c
artridge A , containing the sealant fluid,
equipped with:
•

a f
illing hose B ,
•

a
n adhesive sticker C showing "max.
50
mph (80 km/h)" that the driver
must apply in a
visible place (on the
dashboard) after having repaired the tyre,

F If a pressure of at least 3 bar is not
reached within 5 minutes, disconnect the
compressor from the valve and the power
socket, then move the vehicle for ward by
approximately 10
metres to distribute the
sealant fluid inside the tyre.

i
f a pressure of at least 3 bar is not
reached within 10
minutes, switch off your
vehicle: the tyre has suffered too much
damage and it could not be repaired.

CITROËN dealer or a qualified
workshop.

If it is necessary to deflate the tyre, connect the
hose I to the tyre valve and press the yellow
button, placed in the centre of the switch on the
compressor.

The cartridge contains ethylene glycol, a
product which is harmful if swallowed and
which causes irritation to the eyes.
It must be kept out of the reach of children. After use, do not discard the cartridge
into the environment, take it to an
authorised waste disposal site or
a
CITROËN dealer.

5 - Put away the wheel to be
repaired
You must always place the wheel to be repaired
or the spare wheel under the vehicle to secure
the carrier system.
Check that it is properly secured in its
compartment below the floor.
If the wheel is not correctly in position, it
could be dangerous.
F

R
eplace the wheel at the rear of the vehicle.
Have the tightness of the bolts and the
pressure of the spare wheel checked by
a
member of the dealer network or a qualified
workshop without delay.
Have the punctured wheel repaired and
replace it on the vehicle as soon as possible.
