AUTOMATIC ADJUSTMENT OF THE XENON HEADLAMPS
In order to avoid causing a nuisance
to other road users, this system cor-
rects the height of the xenon head-
lamps beam automatically and when
stationary, in relation to the load in
the vehicle. If a malfunction occurs,
this warning lamp is
displayed on the in-
strument panel, ac-
companied by an audible signal and a
message on the multifunction screen.
The system then places your head-
lamps in the lowest position.
If a malfunction occurs, do not
touch the xenon bulbs. Contact a
CITROËN dealer.
DIRECTIONAL LIGHTING
When the dipped or main beam
headlamps are on, this function ena-
bles the light beam to follow the di-
rection of the road.
The use of this function, coupled
with the xenon headlamps only,
considerably improves the quality of
your lighting when cornering.

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.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting 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.
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. This is indicated by fl ashing
of this warning lamp on the
instrument panel. 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, lo-
cated in the centre of the dash-
board. 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" but-
ton again to reactivate them
manually.
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. 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.

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 invert the seat belt buckles
as they will not fulfi l their role fully.
The seat belts are fi tted with an in-
ertia reel permitting automatic ad-
justment of the length of the strap
to your size. The seat belt is stored
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 rapidly on the strap
and releasing it. In order to be effective, a seat belt:
- must be tightened as close to the
body as possible,
- must restrain one person of adult size only,
- must not bear any trace of cuts or fraying,
- must be pulled in front of you with a smooth movement, checking
that it does not twist,
- must not be altered or modifi ed to avoid altering its performance. 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 accordance with current safety
regulations, all repairs and checks
must be carried out by a CITROËN
dealer who guarantees that the work
is carried out correctly.
Have your seat belts checked regularly
by a CITROËN dealer and 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.
Depending on the nature and
seriousness of the impacts
, the
pre-tensioning device may be trig-
gered before and independently
of the airbags. Triggering of the
pre-tensioners is accompanied
by a slight discharge of harmless
smoke and a noise, due to the acti-
vation 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.

Deactivation
This warning lamp comes on
in the instrument panel when
the ignition is on and until the
airbag is reactivated.
To guarantee the safety of your
child, it is imperative that the pas-
senger airbag is deactivated when
you install a "rearwards-facing" child
seat on the front passenger seat.
Otherwise, the child would risk be-
ing seriously injured or killed if the
airbag were triggered. Reactivation
When you remove the child seat,
turn switch
1 to the "ON" position to
reactivate the airbag and so guaran-
tee the safety of your front passen-
ger in the event of an impact.
Operating fault
Only the front passenger’s airbag
can be deactivated:

 with the ignition off
, insert the
key in the passenger airbag de-
activation switch 1 ,

 turn it to the "OFF" position,

 then, remove the key keeping
the switch in this position.
If this warning lamp comes on
in the instrument panel, accom-
panied by an audible warning
and a message on the multi-
function screen, contact a CITROËN
dealer to have the system checked. The
airbags may no longer be triggered in
the event of a serious impact.
If this warning lamp fl ashes,
contact a CITROËN dealer.
If both airbag warning lamps come
on continuously, do not install a
"rearwards-facing" child seat on
the front passenger seat.
Have it checked by a CITROËN
dealer.
