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 need for the
driver to be vigilant or to drive
responsibly. Puncture
The service warning light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display 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 light
comes on on the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction
display 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 light
comes on on the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display 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
install a wheel which is not detect-
ed 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
features" section) to ensure that the
optimum dynamic performance of
the vehicle is maintained and pre-
vent premature wear of the tyres,
particularly in arduous driving con-
ditions (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 radioelectric
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:
- the anti-lock braking system (ABS),
- the electronic brake force distri- bution (EBFD),
- the emergency braking assis- tance (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 light comes
on, accompanied by an au-
dible signal and a message
on the multi-function display,
it indicates a malfunction of the anti-
lock braking system which could
result in loss of control of the vehicle
when braking.
If this warning light comes on,
together with the STOP and

ABS warning lights, accom-
panied by an audible signal
and a message on the multifunction
display, 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 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 optimises
traction 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 light on the
instrument panel. Disarming
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground, ...), it may
be advisable to disarm 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 fascia. 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.
If this warning light comes
on on the instrument panel
and the indicator light on the
button comes on, this indi-
cates that the ASR and ESP
systems are disarmed. Operating fault
If this warning light comes
on, accompanied by an au-
dible signal and a message
on the multifunction display,
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
vehicle, 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 rolled up 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 col-
lision, emergency braking or if the
vehicle 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 transformed or modi- fi ed to avoid altering its perfor-
mance. Recommendations for children
Use a suitable child seat if the pas-
senger is less than 12 years old or
shorter than one metre fi fty.
Never use the same seat belt to secure
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 regu-
larly by a CITROËN dealer and par-
ticularly 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 rolled up correctly.
Depending on the nature and
seriousness of the impacts
, the
pre-tensioning device may be trig-
gered before and independently of
the air bags. Triggering of the pre-
tensioners 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 air bag warning light
comes on.
Following an impact, have the seat
belts system checked, and if neces-
sary replaced, by a CITROËN dealer.

Deactivation
This warning light comes
on on the instrument panel
when the ignition is on and
until the air bag is re-armed.
To guarantee the safety of your child,
it is imperative that the passenger
air bag is disarmed 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
air bag were triggered. Reactivation
When you remove the child seat,
turn switch
1 to the "ON" position to
re-arm the air bag and so guarantee
the safety of your front passenger in
the event of an impact.
Operating fault
Only the front passenger's air bag
can be disarmed:

 with the ignition off , insert the
key in the passenger air bag dis-
arming switch 1 ,

 turn it to the "OFF" position,

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