TYRE UNDER-INFLATION DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Flat tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punc-
tured or very defl ated tyre), and
have the tyre pressure checked as
soon as possible.
Sensor(s) not detected or faulty
The service warning
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
the need to have the tyre pres-
sure checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic performance
of the vehicle is maintained and
prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (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 detection
system may experience temporary
interference due to radio-electric
emissions on a frequency close to
that used by the system.
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.
The spare wheel is not fi tted with a
sensor.

BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- anti-lock braking system (ABS),
- electronic brake force distribu-tion (EBFD),
- emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the
stability and manoeuvrability of your
vehicle 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
When braking in an emergency,
press very fi rmly without releasing
the pressure. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multi-function screen,
it indicates a malfunction of the anti-
lock braking system which could re-
sult in loss of control of the vehicle
when braking.
If this warning lamp comes
on, together with the STOP
and ABS warning lamps,
accompanied by an audi-
ble signal and a message on the
multifunction screen, it indicates a
malfunction of the electronic 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.
In both cases, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to
the manufacturer's recommenda-
tions. Emergency braking assistance
System which, in an emergency,
enables 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.
When braking in an emergency,
press fi rmly without releasing the
pressure.

for vehicle identifi cation and searches.
The vehicle type identifi cation
number is also indicated on the reg-
istration document.

Tyre pressures
Located on the driver's door interior
pillar.
Use the tyre pressures recom-
mended by CITROËN.
Check the tyre pressures when the
tyres are cold, on a frequent basis.
Never reduce the pressure of a hot
tyre.
If replacing your tyres, it is essen-
tial to use the tyre sizes that are
recommended for your vehicle.

If after around 5 to 7 minutes the
pressure is not attained, this indi-
cates that the tyre is not repaira-
ble; contact a CITROËN dealer for
assistance.

 Switch on the compressor by
moving the switch B to position

"1" until the tyre pressure rea-
ches 2.0 bars.

 Remove the kit, taking care to
avoid to avoid staining your vehi-
cle with traces of fl uid. Keep the
kit to hand.

 Drive immediately for approxima-
tely three miles (fi ve 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.

 Turn the selector A to the AIR
position.

 Connect the black pipe D to the
valve of the wheel.

Take care, this product is
harmful (e.g. ethylene-gly-
col, colophony, ethanediol...)
if swallowed and causes ir-
ritation to the eyes. Keep it out of
reach of children.
The expiry date of the fl uid is indi-
cated on the cartridge.
The sealant cartridge is designed
for single use; even if only partly
used, it must be replaced.
To remove the cartridge, unscrew it
completely at its cap and pull off.
After use, do not discard the car-
tridge 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.

 Connect the compressor's elec-
tric plug to the vehicle's 12 V
socket.

 Start the vehicle again and leave
the engine running.

 Adjust the pressure using the
compressor (to infl ate: switch B
in position "1" ; to defl ate:
switch B in position "0" and
press button E ), in accordance
with the vehicle's tyre pressure
label (located on the left hand
door aperture).
A loss of pressure indicates that the puncture has not been fully
plugged; contact a CITROËN
dealer for assistance.

 Remove and stow the kit.

 Drive at reduced speed (50 mph
[80 km/h] max) limiting the dis-
tance travelled to approximately
120 miles (200 km).
 Go to a CITROËN dealer
as soon as possible.
Have the tyre inspected by a
technician, who can then ad-
vise you whether it can be re-
paired or should be replaced. You can also use this kit for the
routine check and adjustment of
the tyre pressures on your vehicle
and to infl ate other items such as a
ball or bicycle tyre.
