Locking the vehicle with exterior perimeter monitoring only

Deactivate the interior volumetric and
anti-tilt monitoring to avoid unwanted
triggering of the alarm in certain cases
such as:


- leaving a pet in the vehicle,

- leaving a window partially open,

- washing your vehicle,

- changing a wheel,

- having your vehicle towed,

- transport by sea.

Deactivation of the interior
volumetric and anti-tilt monitoring


)
Switch off the ignition.

)
Within ten seconds, press the but-
ton until the indicator lamp is on
continuously.

)
Get out of the vehicle.

Tr iggering of the alarm


This is indicated by sounding of the siren
and fl ashing of the direction indicators
for thirty seconds.
The monitoring functions remain active
until the alarm has been triggered eleven
times in succession.
When the vehicle is unlocked using the
remote control, rapid fl ashing of the in-
dicator lamp in the button informs you
that the alarm was triggered during your
absence. When the ignition is switched
on, this fl ashing stops immediately.

Failure of the remote control

To deactivate the monitoring functions:



)
Unlock the vehicle using the key in
the driver's door lock.

Children under the age of 10 must
not travel in the "forwards-facing"
position on the front passenger seat,
unless the rear seats are already oc-
cupied by other children, cannot be
used or are absent.
Deactivate the passenger airbag
when a "rearwards-facing" child seat
is installed on the front seat.
Otherwise, the child would risk being
seriously injured or killed if the airbag
were to infl ate.

ADVICE ON CHILD SEATS

As a safety precaution, do not leave:


- a child or children alone and un-
supervised in a vehicle,

- a child or an animal in a vehicle
which is exposed to the sun, with
the windows closed,

- the keys within reach of children
inside the vehicle.
To prevent accidental opening of the
doors and rear windows, use the
"Child lock".
Take care not to open the rear win-
dows by more than one third.
To protect young children from the
rays of the sun, fi t side blinds on the
rear windows.


Installing a booster seat
The chest part of the seat belt must
be positioned on the child's shoulder
without touching the neck.
Ensure that the lap part of the seat
belt passes correctly over the child's
thighs.
CITROËN recommends the use of a
booster seat which has a back, fi tted
with a seat belt guide at shoulder level. The incorrect installation of a child
seat in a vehicle compromises the
child's protection in the event of an
accident.
Remember to fasten the seat belts or
the child seat harnesses keeping the
slack relative to the child's body to a
minimum, even for short journeys.
When installing a child seat using the
seat belt, ensure that the seat belt is
tightened correctly on the child seat
and that it secures the child seat fi rmly
on the seat of your vehicle. Move the
seat forwards if necessary.
For optimum installation of the "for-
wards-facing" child seat, ensure that
the back of the child seat is in contact
with the back of the vehicle's seat
and that the head restraint does not
cause any discomfort.
If the head restraint has to be re-
moved, ensure that it is stored or
attached securely to prevent it from
being thrown around the vehicle in
the event of sharp braking.

SAFETY
132
BRAKING ASSISTANCESYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:


- anti-lock braking system (ABS),

- electronic brake force distribution
(EBFD),

- emergency braking assistance (EBA).

When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.

and electronic brake force distribution

Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle 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
If this warning lamp comes on,
accompanied by an audible sig-
nal and a message in the mul-
tifunction screen, it indicates a
malfunction of the anti-lock braking sys-
tem which could result in loss of control
of the vehicle when braking.
If this warning lamp comes on,
together with the STOP
and
ABS
warning lamps, accompa-
nied by an audible signal and a
message in the multifunction screen, it
indicates a malfunction of the electron-
ic 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.

Emergency braking assistance

System which, in an emergency, en-
ables 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.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.
