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 distribution (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 multifunction 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 audible
signal and a message on the multi-
function screen, it indicates a mal-
function 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 either case, 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.

SEAT BELTS
Front seat belts
The front seat belts are fi tted with a
pretensioning system and force limiter.
This system improves safety in the front
seats in the event of a front impact. Fastening

 Pull the belt down in front of you
in a steady movement, making
sure that it does not become
twisted.


Press the fastening into its buckle.

 Check that it is properly secured
and that the automatic locking
mechanism operates correctly
by pulling sharply on the belt
strap.

 The abdominal part of the strap
should be positioned as low
down as possible in the lap and
as tight as possible.

 The chest part should be posi-
tioned if possible in the channel
of the shoulder.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant.
Depending on the seriousness of the
impact, the pretensioning system in-
stantly tightens the seat belt against
the body of the occupant.
The pretensioning seat belts are
active when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
their protection.

Storing the seat belt
(3-door model)
Raise then lock part A , to retain the
seat belt buckle when it is unfas-
tened.
It is necessary to remove the seat
belt from the buckle retainer before
moving the seat to access the rear
seat positions.
As a safety measure, these operations
should only be done when stationary.
Seat belt height adjustment
(5-door model)
Correct adjustment of the upper
mounting places the diagonal belt at
mid-shoulder level.

 To adjust the belt, squeeze the
control and slide it in the direc-
tion required.
Unfastening

 To unfasten the belt, press on
the red button in the buckle.
The belt retracts automatically when
not in use. Rear seat belts
Each rear seat is fi tted with a three-
point inertia reel 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 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
automatic locking device which
comes into operation in the event
of a collision, emergency braking or
if the vehicle rolls over. You can re-
lease the device by pulling fi rmly on
the strap and releasing it so that it
re-winds 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. 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 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 reeled in correctly. In the event of an impact

Depending on the nature and se-
riousness of the impacts , the pre-
tensioning device may be triggered
before and independently of the
airbags. Triggering of the pre-ten-
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.

as required.

 Check, in the instrument panel,
the position engaged.

 Gradually release the brake pedal
and accelerate.

 To avoid a difference between
the position of the selector and
the actual position of the gear-
box, only exit from position P
with the ignition on and the brake
pedal pressed.
Park Reverse gear
This position of the selector is used
to prevent the vehicle from moving
when you are stationary.

 To select position P , move the
selector back to the highest po-
sition (towards R ), then push it
forwards and then to the left. Only engage this position when
the vehicle is stationary. To prevent
snatching, do not accelerate too
soon after selection.
Neutral
Never select position N if the vehicle
is moving.
Never select positions P or

R if the vehicle is not sta-
tionary.
If, while the vehicle is moving, po-
sition N is engaged inadvertently,
allow the engine to idle before en-
gaging position D or M .
Otherwise, when the ignition is on or
the engine is running:


reposition the selector in position P ,

 put your foot on the brake pedal
and then select the gear you want. Automatic operation

 Move the selector to position D .
The gearbox constantly selects the gear that is best suited to the
following conditions:
- driving style,
- road profi le,
- vehicle load.
The gearbox is then operating in

auto-adaptive mode, without re-
quiring any action on your part.
For certain manoeuvres (for exam-
ple overtaking), you can obtain ma-
ximum acceleration by pressing the
accelerator pedal down hard, which
then produces an automatic change
down to a lower gear.
When braking, the gearbox may
change down automatically in order
to provide effective engine braking.
If you lift your foot off the accelerator
abruptly, the gearbox will not change up.

 To exit position P , move the se-
lector to the right and then to the
position you want.

 Only engage this position when
the vehicle is completely sta-
tionary. In this position, the front
wheels are locked. Make sure
that the selector is correctly po-
sitioned.

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING SENSORS
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking sensors are
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward gear,
- when the vehicle has been station- ary for more than three seconds in
forward gear.
The parking sensor system cannot,
in any circumstances, replace the
need for vigilance and responsibility
on the part of the driver.
The parking sensors are
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and display of the vehicle on
the multifunction screen.
The proximity information is indica-
ted by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres, the
audible signal becomes continuous
and/or the "Danger" symbol appears,
depending on the multifunction screen
version.
