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
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. 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.

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.

Maximum application is essential:
- in the case of a vehicle towing a caravan or a trailer, if the au-
tomatic functions are activated
but you are applying the parking
brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a ferry, in a lorry, during towing),
- in the case of towing, a loaded vehicle or parking on a gradient,
turn the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer. Particular situations
In certain situations (e.g. starting
the engine), the parking brake can
automatically alter its force. This is
