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 ASSISTANCE
SYSTEMS
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.



Anti-lock braking system
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
signal and a message in the
screen, it indicates a malfunc-
tion of the anti-lock braking system
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 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.











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.

TRAJECTORY CONTROL
SYSTEMS (ESP)

Anti-slip regulation (ASR) and
electronic stability control
(ESC)

The anti-slip regulation (also known as
traction control) optimises traction to pre-
vent skidding of the wheels, by acting on
the brakes of the driving wheels and on
the engine.
The electronic stability control acts on
the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver, within
the limits of the laws of physics.

Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
This is indicated by fl ashing of
this warning lamp in the instru-
ment panel.








Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving
on snow: intelligent traction control.
This system detects situations of diffi -
cult surface adhesion that could make it
diffi cult to move off or make progress on
deep fresh snow or compacted snow.
In these situations, the intelligent trac-
tion control
limits the amount of wheel
slip to provide the best traction and tra-
jectory control for your vehicle.

Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), if you are un-
able to make progress, it may be ad-
visable to temporarily deactivate these
systems, so that the wheels can spin
freely and allow the vehicle to move.


)
Press the "ESP OFF"
button, located
near the steering wheel.

If this warning lamp comes on in the in-
strument panel and the indicator lamp
in the button comes on, this indicates
that these systems are deactivated.

The use of snow tyres is strongly
recommended on surfaces offer-
ing low levels of adhesion.

It is recommended that the systems be
reactivated as soon as possible.

SAFETY
139
The trajectory control systems
offer increased safety in normal
driving, but this should not en-
courage the driver to take extra
risks or drive at high speed.
The correct functioning of these
systems is assured provided
that manufacturer's recommen-
dations are observed on:


- wheels (tyres and rims),

- braking components,

- electronic components,

- assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.

Reactivation
These systems are reactivated automati-
cally 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.

If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, this indicates a fault
with these systems.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.

SEAT BELTS

Front seat belts


The front seat belts are fi tted with a pre-
tensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side im-
pact. Depending on the severity of the
impact, the pretensioning system in-
stantly tightens the seat belts against
the body of the occupants.
The pretensioning seat belts are active
when the ignition is on.
The force limiter reduces the pressure
of the seat belt on the chest of the oc-
cupant, so improving their protection.











Fastening


)
Pull the strap, then insert the tongue
in the buckle.

)
Check that the seat belt is fastened
correctly by pulling the strap.


Unfastening


)
Press the red button on the buckle.

)
Guide the seat belt as it reels in.
The corresponding warning lamp 1
or 2

comes on in red on the seat belt and pas-
senger's front airbag warning lamps dis-
play, accompanied by an audible signal
and a message in the screen, if the seat
belt is not fastened or is unfastened.

From approximately 12 mph (20 km/h)
this warning lamp fl ashes for two min-
utes accompanied by an audible signal
of increasing volume. Once these two
minutes have elapsed, this warning
lamp remains on until the driver and/or
the front passenger fastens their seat
belt.

The driver must ensure that passen-
gers use the seat belts correctly and
that they are all restrained securely
before setting off.
Wherever you are seated in the ve-
hicle, always fasten your seat belt,
even for short journeys.
Do not interchange the seat belt
buckles as they will not fulfi l their role
fully.
The seat belts are fi tted with an inertia
reel permitting automatic adjustment
of the length of the strap to your size.
The seat belt is stowed automatically
when not in use.
Before and after use, ensure that the
seat belt is reeled in correctly.
The lower part of the strap must be
positioned as low as possible on the
pelvis.
The upper part must be positioned in
the hollow of the shoulder.
The inertia reels are fi tted with an au-
tomatic locking device which comes
into operation in the event of a colli-
sion, emergency braking or if the ve-
hicle rolls over. You can release the
device by pulling fi rmly on the strap
and releasing it so that it reels in
slightly. In order to be effective, a seat belt
must:


- be tightened as close to the body
as possible,

- be pulled in front of you with a
smooth movement, checking that
it does not twist,

-
be used to restrain only one person,


- not bear any trace of cuts or fraying,


- not be converted or modifi ed to
avoid affecting its performance.
In accordance with current safety
regulations, for all repairs on your ve-
hicle, go to a qualifi ed workshop with
the skills and equipment needed,
which a CITROËN dealer is able to
provide.
Have your seat belts checked regu-
larly by a CITROËN dealer or a
qualifi ed workshop, particularly if the
straps show signs of damage.
Clean the seat belt straps with soapy
water or a textile cleaning product,
sold by CITROËN dealers.
After folding or moving a seat or rear
bench seat, ensure that the seat belt
is positioned and reeled in correctly.
Recommendations for children
Use a suitable child seat if the pas-
senger is less than 12 years old or
shorter than one and a half metres.
Never use the same seat belt to se-
cure more than one person.
Never allow a child to travel on your
lap.

In the event of an impact

Depending on the nature and se-
riousness of the impact
, the pre-
tensioning device may be deployed
before and independently of the
airbags. Deployment of the preten-
sioners is accompanied by a slight
discharge of harmless smoke and
a noise, due to the activation of the
pyrotechnic cartridge incorporated in
the system.
In all cases, the airbag warning lamp
comes on.
Following an impact, have the seat
belts system checked, and if neces-
sary replaced, by a CITROËN dealer
or a qualifi ed workshop.

Deactivation
Only the passenger's front airbag can
be deactivated:


)
insert the key in the passenger air-
bag deactivation switch,

)
turn it to the "OFF"
position,

)
then, remove the key keeping the
switch in the new position.
According to version, this warn-
ing lamp comes on in the in-
strument panel and/or in the
seat belt and passenger's front
airbag warning lamps display when the
ignition is on and until the airbag is re-
activated. To assure the safety of your child,
the passenger's front airbag
must be deactivated when you
install a "rear facing" child seat
on the front passenger seat.
Otherwise, the child would risk
being seriously injured or killed if
the airbag were deployed.

Reactivation
When you remove the child seat, turn
the switch to the "ON"
position to re-
activate the airbag and so assure the
safety of your front passenger in the
event of an impact.
With the ignition on, this warn-
ing lamp comes on in the seat
belt and passenger's front air-
bag warning lamps display for
approximately one minute, if the pas-
senger's front airbag is activated.
Operating fault
If this warning lamp comes on
in the instrument panel, accom-
panied by an audible warning
and the display of a message,
contact a CITROËN dealer or a qualifi ed
workshop to have the system checked.
The airbags may no longer be deployed
in the event of a serious impact.
If this warning lamp fl ashes in
the instrument panel and/or in
the seat belt and passenger's
front airbag warning lamps dis-
play, contact a CITROËN dealer or a
qualifi ed workshop. The passenger's
front airbag may no longer be deployed
in the event of a serious impact.
If even one of the two airbag
warning lamps comes on contin-
uously, do not install a child seat
on the front passenger seat.
