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 instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
screen locating the wheel
concerned.
Stop immediately, avoiding any sudden
movement of the steering wheel and
the brakes.
Change the damaged wheel (punctured
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 perform-
ance 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 distribution (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 multifunction 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, accom-
panied by an audible 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 either case, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations. 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.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing on the brakes of the driving wheels
and on the engine.
The electronic stability programme acts
on the brake of one or more wheels
and on the engine to keep the vehicle
on the trajectory required by the driver. Deactivation
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.


Press the "ESP OFF" button, located
in the centre of the dashboard.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated.
This is indicated by fl ashing
of this warning lamp on the
instrument panel.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. Intelligent Traction Control
system *
Your vehicle has a system to help
driving on snow.
This automatic system continuously
checks for situations of diffi cult sur-
face adhesion that could make it dif-
fi cult to move off or make progress
on deep fresh snow or compacted
snow.
In these situations, the system takes
over from the
ASR system by opti-
mising the amount of wheel slip to
provide the best traction and trajec-
tory control, even without snow tyres
and with or without chains.
In extremely severe conditions (snow
on top of ice, sand, deep mud…), it
can be useful to deactivate the ESP/
ASR systems to allow a degree of
wheel spin and so recover grip.
* Depending on engine type.

Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).


Press the "ESP OFF" button again to reactivate them manually.
Operating fault If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer. The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.

SEAT BELTS
Front seat belts
The front seat belts are fi tted with a
pretensioning system and force limiter.
This system improves safety in the front
seats in the event of a front impact.
Depending on the seriousness of the
impact, the pretensioning system in-
stantly tightens the seat belt against
the body of the occupant. Fastening

 Pull the belt down in front of you
in a steady movement, making
sure that it does not become
twisted.

 Press the fastening into its buckle.

 Check that it is properly secured
and that the automatic locking
mechanism operates correctly
by pulling sharply on the belt
strap.

 The lap strap should be posi-
tioned as low down as possible in
the lap and as tight as possible.

 The diagonal strap should be
positioned across the chest and
away from the neck.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant. Height adjustment
The pretensioning seat belts are ac-
tive when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
his protection.
When correctly adjusted, the seat
belt shoulder strap falls over the
middle of the shoulder.

 To adjust the belt, squeeze the
control and slide it in the direction
required.
Unfastening

 To unfasten the belt, press on
