TYRE UNDER-INFLATION DETECTION
System which automatically and continu-
ously checks the pressure of the tyres
while driving.
Sensors fi tted in each valve trigger a
warning in the event of problem (speed
above 12 mph (20 km/h)).
This warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal,
to identify the wheel concerned.

Under-infl ated tyre
The STOP
warning lamp
comes on and/or this warn-
ing lamp is displayed on the
instrument panel, accompa-
nied by an audible signal and
a message in the screen iden-
tifying the wheel concerned.


)
Stop as soon as it is safe to do so,
avoiding any sudden movement of
the steering wheel and the brakes.

)
Repair or change the damaged
wheel (punctured or very defl ated
tyre), and have the tyre pressure
checked as soon as possible.

Puncture

Sensor(s) not detected or faulty
A message appears in the screen, ac-
companied by an audible signal, to
identify the wheel or wheels which are
not detected or to indicate a malfunc-
tion in the system.
Contact a CITROËN dealer or a quali-
fi ed workshop to replace the faulty
sensor(s).
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired)
or when one or more wheels
without a sensor are fi tted.
If your vehicle is equipped with
a spare wheel, this is not fi tted
with a sensor. All repairs and changing of tyres
on a wheel fi tted with this sys-
tem must be carried out by a
CITROËN dealer or a qualifi ed
workshop.
If, when changing a tyre, you
install a wheel which is not de-
tected by your vehicle (example:
fi tting of snow tyres), you must
have the system reinitialised by
a CITROËN dealer or a qualifi ed
workshop.
The tyre under-infl ation detec-
tion system is an aid to driving
which does not replace the need
for the driver to be vigilant or to
drive responsibly. This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the ve-
hicle is maintained and prevent
premature wear of the tyres, par-
ticularly in arduous driving condi-
tions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detec-
tion system may experience
temporary interference due to
electro-magnetic emissions on a
frequency close to that used by
the system.


)
Check the tyre pressures as soon
as possible.
This check must be carried out when
the tyres are cold.

BRAKING ASSISTANCESYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:


- anti-lock braking system (ABS),

- electronic brake force distribution
(EBFD),

- emergency braking assistance (EBA).

When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.

and electronic brake force distribution

Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.

Activation
The anti-lock braking system comes
into operation automatically when there
is a risk of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal.
Operating fault
If this warning lamp comes on,
accompanied by an audible sig-
nal and a message in the mul-
tifunction screen, it indicates a
malfunction of the anti-lock braking sys-
tem which could result in loss of control
of the vehicle when braking.
If this warning lamp comes on,
together with the STOP
and
ABS
warning lamps, accompa-
nied by an audible signal and a
message in the multifunction screen, it
indicates a malfunction of the electron-
ic brake force distribution which could
result in loss of control of the vehicle
when braking.

You must stop as soon as it is safe
to do so.

Emergency braking assistance

System which, in an emergency, en-
ables you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.

Activation
It is triggered by the speed at which the
brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase
in braking effi ciency.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.

Tyre under-infl ation detection

If the vehicle is fi tted with tyre under-
infl ation detection, the under-infl ation
warning lamp will remain on after the
wheel has been repaired until the
system is reinitialised by a CITROËN
dealer or a qualifi ed workshop.


If after around 5 to 7 minutes the
pressure is not attained, this indi-
cates that the tyre is not repairable;
contact a CITROËN dealer or a
qualifi ed workshop for assistance.
)
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).
)
Remove the kit and screw the cap
back on the white pipe.
Take care to avoid staining your ve-
hicle with traces of fl uid. Keep the
kit to hand.

)

Drive immediately for approximately
three miles (fi ve kilometres), at re-
duced speed (between 15 and 35 mph
[20 and 60 km/h]), to plug the punc-
ture.

)
Stop to check the repair and the tyre
pressure using the kit.
