malfunction (speed above 12 mph
(20 km/h)).
Flat tyre T h e t y r e u n d e r - i n fl a t i o n d e t e c t i o n
system is an aid to driving which
does not replace the need for the
driver to be vigilant or to drive re-
sponsibly. 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 instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function display locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
o r v e r y d e fl a t e d t y r e ) , a n d h a v e t h e t y r e
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning light
comes on on the instru-
ment panel, accompa-
nied by an audible signal
and a message on the
multifunction display lo-
cating 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
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
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
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
features" 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.

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 assist- ance (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,
p r e s s v e r y fi r m l y w i t h o u t r e l e a s i n g
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 re-
sult 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 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
i n c r e a s e i n b r a k i n g e f fi c i e n c y .
When braking in an emergency,
p r e s s fi r m l y w i t h o u t r e l e a s i n g t h e

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. T h i s i s i n d i c a t e d b y fl a s h i n g
of this warning light on the
instrument panel. Disarming
I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g 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.
T h e E S P / A S R s y s t e m s o f f e r e x -
ceptional safety in normal driving,
but this should not encourage the
d r i v e r t o t a k e e x t r a r i s k s o r d r i v e a t
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
a s t h e y w i l l n o t f u l fi l t h e i r r o l e f u l l y .
T h e s e a t b e l t s a r e fi t t e d w i t h a n
inertia 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.
T h e i n e r t i a r e e l s a r e fi t t e d w i t h a n
automatic locking device which
comes into operation in the event
of a collision, 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 e d t o a v o i d a l t e r i n g i t s p e r f o r m -
ance. Recommendations for children
Use a suitable child seat if the
passenger is less than 12 years old
o r s h o r t e r t h a n o n e m e t r e fi f t y .
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
w a t e r o r a t e x t i l e c l e a n i n g p r o d u c t ,
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 se-
riousness of the impacts
, the pre-
tensioning device may be triggered
before and independently of the air
bags. Triggering of the pre-tensioners
is accompanied by a slight dis-
charge 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.

safety of the occupants (with the
e x c e p t i o n o f t h e r e a r c e n t r e p a s -
senger) in the event of violent col-
lisions. It supplements the action of
the force-limiting seat belts.
If a collision occurs, the electronic
detectors record and analyse the
front and side impacts sustained in
the impact detection zones:
- in the case of a serious impact, the air bags are triggered instant-
ly and protect the occupants of
t h e v e h i c l e ( w i t h t h e e x c e p t i o n o f
the rear centre passenger); im-
mediately after the impact, the
a i r b a g s d e fl a t e r a p i d l y s o t h a t
they do not hinder visibility or the
e x i t o f t h e o c c u p a n t s ,
- in the case of a minor or rear im- pact or in certain roll-over con-
ditions, the air bags will not be
triggered; the seat belt alone is
s u f fi c i e n t t o p r o v i d e o p t i m u m
protection in these situations.
The air bags do not operate
when the ignition is switched
off.
This equipment will only operate
once. If a second impact occurs
(during the same or a subsequent
accident), the air bag will not operate. Impact detection zones
A. Front impact zone.
B. Side impact zone.
Triggering of the air bag(s) is ac-
companied by a slight emission of
harmless smoke and a noise, due
to the activation of the pyrotechnic
cartridge incorporated in the system.
This smoke is not harmful, but sen-
s i t i v e i n d i v i d u a l s m a y e x p e r i e n c e
slight irritation.
The noise of the detonation may
result in a slight loss of hearing for
a short time. Front air bags
System which protects the head and
chest of the driver and front passen-
ger in the event of a front impact.
The driver's air bag is incorporated
in the centre of the steering wheel;
the front passenger's air bag is in-
corporated in the fascia above the
g l o v e b o x .
Activation
The air bags are triggered simultane-
ously, unless the passenger's front
air bag is disarmed, in the event of
a serious front impact applied to all
or part of the front impact zone
A ,
in the longitudinal centreline of the
vehicle on a horizontal plane and di-
rected from the front to the rear of
the vehicle.
T h e f r o n t a i r b a g i n fl a t e s b e t w e e n
the front occupant of the vehicle and
the fascia to cushion his forward
movement.

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
If this warning light comes on on
the instrument panel, accompa-
nied by an audible warning and
a message on the multifunction
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.
I f t h i s w a r n i n g l i g h t fl a s h e s ,
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.
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.
